FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

Aspirin and extended-release dipyridamole capsules are indicated to reduce the risk of stroke in patients who have had transient ischemia of the brain or completed ischemic stroke due to thrombosis.

2 DOSAGE AND ADMINISTRATION

Aspirin and extended-release dipyridamole capsules are not interchangeable with the individual components of aspirin and dipyridamole tablets.

The recommended dose of aspirin and extended-release dipyridamole capsules is one capsule given orally twice daily, one in the morning and one in the evening. Swallow capsules whole without chewing. Aspirin and extended-release dipyridamole capsules can be administered with or without food.

2.1 Alternative Regimen in Case of Intolerable Headaches

In the event of intolerable headaches during initial treatment, switch to one capsule at bedtime and low-dose aspirin in the morning. Because there are no outcome data with this regimen and headaches become less of a problem as treatment continues, patients should return to the usual regimen as soon as possible, usually within one week.

3 DOSAGE FORMS AND STRENGTHS

25 mg/200 mg capsules with a red opaque cap and a yellow opaque body, filled with light yellow to yellow extended-release dipyridamole pellets and a white to off-white, round, film-coated, biconvex, unscored, plain aspirin tablet. The capsule is imprinted axially with “AN” in yellow ink on the cap and “596” in red ink on the body.

4 CONTRAINDICATIONS

4.1 Hypersensitivity

Aspirin and extended-release dipyridamole capsules are contraindicated in patients with known hypersensitivity to any of the product components.

4.2 Allergy

Aspirin, USP is contraindicated in patients with known allergy to nonsteroidal anti-inflammatory drug (NSAID) products and in patients with the syndrome of asthma, rhinitis and nasal polyps. Aspirin, USP may cause severe urticaria, angioedema or bronchospasm.

4.3 Reye Syndrome

Do not use aspirin, USP in children or teenagers with viral infections because of the risk of Reye syndrome.

5 WARNINGS AND PRECAUTIONS

5.1 Risk of Bleeding

Aspirin and extended-release dipyridamole increases the risk of bleeding. Risk factors for bleeding include the use of other drugs that increase the risk of bleeding (e.g., anticoagulants, antiplatelet agents, heparin, anagrelide, fibrinolytic therapy and chronic use of NSAIDs) [see Drug Interactions (7.1)] .

Intracranial Hemorrhage
In European Stroke Prevention Study-2 (ESPS2), the incidence of intracranial hemorrhage was 0.6% in the aspirin and extended-release dipyridamole group, 0.5% in the extended-release dipyridamole (ER-DP) group, 0.4% in the aspirin (ASA) group and 0.4% in the placebo groups.

Gastrointestinal (GI) Side Effects
GI side effects include stomach pain, heartburn, nausea, vomiting and gross GI bleeding. Although minor upper GI symptoms, such as dyspepsia, are common and can occur anytime during therapy, physicians should remain alert for signs of ulceration and bleeding, even in the absence of previous GI symptoms. Inform patients about the signs and symptoms of GI side effects and what steps to take if they occur.

In ESPS2, the incidence of gastrointestinal bleeding was 4.1% in the aspirin and extended-release dipyridamole group, 2.2% in the extended-release dipyridamole group, 3.2% in the aspirin group and 2.1% in the placebo groups.

Peptic Ulcer Disease
Avoid using aspirin in patients with a history of active peptic ulcer disease, which can cause gastric mucosal irritation and bleeding.

Alcohol Warning
Because aspirin and extended-release dipyridamole capsules contain aspirin, counsel patients who consume three or more alcoholic drinks every day about the bleeding risks involved with chronic, heavy alcohol use while taking aspirin.

5.2 Renal Failure

Avoid aspirin in patients with severe renal failure (glomerular filtration rate less than 10 mL/minute) [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)] .

5.3 Hepatic Insufficiency

Elevations of hepatic enzymes and hepatic failure have been reported in association with dipyridamole administration [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)] .

5.4 Pregnancy

Because aspirin and extended-release dipyridamole capsules contain aspirin, aspirin and extended-release dipyridamole capsules can cause fetal harm when administered to a pregnant woman. Maternal aspirin use during later stages of pregnancy may cause low birth weight, increased incidence for intracranial hemorrhage in premature infants, stillbirths and neonatal death. Because of the above and because of the known effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the fetal cardiovascular system (closure of the ductus arteriosus), avoid aspirin and extended-release dipyridamole in the third trimester of pregnancy [see Use in Specific Populations (8.1)] .

Aspirin has been shown to be teratogenic in rats (spina bifida, exencephaly, microphthalmia and coelosomia) and rabbits (congested fetuses, agenesis of skull and upper jaw, generalized edema with malformation of the head and diaphanous skin) at oral doses of 330 mg/kg/day and 110 mg/kg/day, respectively. These doses, which also resulted in a high resorption rate in rats (63% of implantations versus 5% in controls), are, on a mg/m 2 basis, about 66 and 44 times, respectively, the dose of aspirin contained in the maximum recommended daily human dose of aspirin and extended-release dipyridamole. Reproduction studies with dipyridamole have been performed in mice, rabbits and rats at oral doses of up to 125 mg/kg, 40 mg/kg and 1,000 mg/kg, respectively (about 1½, 2 and 25 times the maximum recommended daily human oral dose, respectively, on a mg/m 2 basis) and have revealed no evidence of harm to the fetus due to dipyridamole. When 330 mg aspirin/kg/day was combined with 75 mg dipyridamole/kg/day in the rat, the resorption rate approached 100%, indicating potentiation of aspirin-related fetal toxicity. There are no adequate and well-controlled studies of the use of aspirin and extended-release dipyridamole in pregnant women. If aspirin and extended-release dipyridamole is used during pregnancy, or if the patient becomes pregnant while taking aspirin and extended-release dipyridamole, inform the patient of the potential hazard to the fetus.

5.5 Coronary Artery Disease

Dipyridamole has a vasodilatory effect. Chest pain may be precipitated or aggravated in patients with underlying coronary artery disease who are receiving dipyridamole.

For stroke or TIA patients for whom aspirin is indicated to prevent recurrent myocardial infarction (MI) or angina pectoris, the aspirin in this product may not provide adequate treatment for the cardiac indications.

5.6 Hypotension

Dipyridamole produces peripheral vasodilation, which can exacerbate pre-existing hypotension.

5.7 General

Aspirin and extended-release dipyridamole capsules are not interchangeable with the individual components of aspirin and dipyridamole tablets.

6 ADVERSE REACTIONS

The following adverse reactions are discussed elsewhere in the labeling:

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The efficacy and safety of aspirin and extended-release dipyridamole was established in the European Stroke Prevention Study-2 (ESPS2). ESPS2 was a double-blind, placebo-controlled study that evaluated 6,602 patients over the age of 18 years who had a previous ischemic stroke or transient ischemic attack within ninety days prior to entry. Patients were randomized to either aspirin and extended-release dipyridamole, aspirin, ER-DP, or placebo [see Clinical Studies (14)] ; primary endpoints included stroke (fatal or nonfatal) and death from all causes.

This 24-month, multicenter, double-blind, randomized study (ESPS2) was conducted to compare the efficacy and safety of aspirin and extended-release dipyridamole with placebo, extended-release dipyridamole alone and aspirin alone. The study was conducted in a total of 6,602 male and female patients who had experienced a previous ischemic stroke or transient ischemia of the brain within three months prior to randomization.

Table 1 presents the incidence of adverse events that occurred in 1% or more of patients treated with aspirin and extended-release dipyridamole where the incidence was also greater than in those patients treated with placebo. There is no clear benefit of the dipyridamole/aspirin combination over aspirin with respect to safety.

    Other Adverse Events
    Adverse reactions that occurred in less than 1% of patients treated with aspirin and extended-release dipyridamole in the ESPS2 study and that were medically judged to be possibly related to either dipyridamole or aspirin are listed below.

    Body as a Whole: Allergic reaction, fever

    Cardiovascular: Hypotension

    Central Nervous System: Coma, dizziness, paresthesia, cerebral hemorrhage, intracranial hemorrhage, subarachnoid hemorrhage

    Gastrointestinal: Gastritis, ulceration and perforation

    Hearing and Vestibular Disorders: Tinnitus and deafness. Patients with high frequency hearing loss may have difficulty perceiving tinnitus. In these patients, tinnitus cannot be used as a clinical indicator of salicylism

    Heart Rate and Rhythm Disorders: Tachycardia, palpitation, arrhythmia, supraventricular tachycardia

    Liver and Biliary System Disorders: Cholelithiasis, jaundice, hepatic function abnormal

    Metabolic and Nutritional Disorders: Hyperglycemia, thirst

    Platelet, Bleeding and Clotting Disorders: Hematoma, gingival bleeding

    Psychiatric Disorders: Agitation

    Reproductive: Uterine hemorrhage

    Respiratory: Hyperpnea, asthma, bronchospasm, hemoptysis, pulmonary edema

    Special Senses Other Disorders: Taste loss

    Skin and Appendages Disorders: Pruritus, urticaria

    Urogenital: Renal insufficiency and failure, hematuria

    Vascular (Extracardiac) Disorders: Flushing

    Laboratory Changes

    Over the course of the 24-month study (ESPS2), patients treated with aspirin and extended-release dipyridamole showed a decline (mean change from baseline) in hemoglobin of 0.25 g/dL, hematocrit of 0.75% and erythrocyte count of 0.13x10 6/mm 3.

    6.2 Post-Marketing Experience

    The following is a list of additional adverse reactions that have been reported either in the literature or are from post-marketing spontaneous reports for either dipyridamole or aspirin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate reliably their frequency or establish a causal relationship to drug exposure. Decisions to include these reactions in labeling are typically based on one or more of the following factors: (1) seriousness of the reaction, (2) frequency of reporting, or (3) strength of causal connection to aspirin and extended-release dipyridamole.

    Body as a Whole: Hypothermia, chest pain

    Cardiovascular: Angina pectoris

    Central Nervous System: Cerebral edema

    Fluid and Electrolyte: Hyperkalemia, metabolic acidosis, respiratory alkalosis, hypokalemia

    Gastrointestinal: Pancreatitis, Reye syndrome, hematemesis

    Hearing and Vestibular Disorders: Hearing loss

    Immune System Disorders: Hypersensitivity, acute anaphylaxis, laryngeal edema

    Liver and Biliary System Disorders: Hepatitis, hepatic failure

    Musculoskeletal: Rhabdomyolysis

    Metabolic and Nutritional Disorders: Hypoglycemia, dehydration

    Platelet, Bleeding and Clotting Disorders: Prolongation of the prothrombin time, disseminated intravascular coagulation, coagulopathy, thrombocytopenia

    Reproductive: Prolonged pregnancy and labor, stillbirths, lower birth weight infants, antepartum and postpartum bleeding

    7 DRUG INTERACTIONS

    7.1 Drug Interaction Study Information Obtained From Literature

    Adenosine
    Dipyridamole has been reported to increase the plasma levels and cardiovascular effects of adenosine. Adjustment of adenosine dosage may be necessary.

    Angiotensin Converting Enzyme (ACE) Inhibitors
    Due to the indirect effect of aspirin on the renin-angiotensin conversion pathway, the hyponatremic and hypotensive effects of ACE inhibitors may be diminished by concomitant administration of aspirin.

    Acetazolamide
    Concurrent use of aspirin and acetazolamide can lead to high serum concentrations of acetazolamide (and toxicity) due to competition at the renal tubule for secretion.

    Anticoagulants and Antiplatelets
    Patients taking aspirin and extended-release dipyridamole in combination with anticoagulants, antiplatelets, or any substance impacting coagulation are at increased risk for bleeding. Aspirin can displace warfarin from protein binding sites, leading to prolongation of both the prothrombin time and the bleeding time. Aspirin can increase the anticoagulant activity of heparin, increasing bleeding risk.

    Anagrelide
    Patients taking aspirin in combination with anagrelide are at an increased risk of bleeding.

    Anticonvulsants
    Salicylic acid can displace protein-bound phenytoin and valproic acid, leading to a decrease in the total concentration of phenytoin and an increase in serum valproic acid levels.

    Beta Blockers
    The hypotensive effects of beta blockers may be diminished by the concomitant administration of aspirin due to inhibition of renal prostaglandins, leading to decreased renal blood flow and salt and fluid retention.

    Cholinesterase Inhibitors
    Dipyridamole may counteract the anticholinesterase effect of cholinesterase inhibitors, thereby potentially aggravating myasthenia gravis.

    Diuretics
    The effectiveness of diuretics in patients with underlying renal or cardiovascular disease may be diminished by the concomitant administration of aspirin due to inhibition of renal prostaglandins, leading to decreased renal blood flow and salt and fluid retention.

    Methotrexate
    Salicylate can inhibit renal clearance of methotrexate, leading to bone marrow toxicity, especially in the elderly or renal impaired.

    Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
    The concurrent use of aspirin with other NSAIDs may increase bleeding or lead to decreased renal function.

    Oral Hypoglycemics
    Moderate doses of aspirin may increase the effectiveness of oral hypoglycemic drugs, leading to hypoglycemia.

    Uricosuric Agents (probenecid and sulfinpyrazone)
    Salicylates antagonize the uricosuric action of uricosuric agents.

    8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Teratogenic Effects, Pregnancy Category D. [see Warnings and Precautions (5.4)].

    8.2 Labor and Delivery

    Aspirin can result in excessive blood loss at delivery as well as prolonged gestation and prolonged labor. Because of these effects on the mother and because of adverse fetal effects seen with aspirin during the later stages of pregnancy [see Warnings and Precautions (5.4)] , avoid aspirin and extended-release dipyridamole in the third trimester of pregnancy and during labor and delivery.

    8.3 Nursing Mothers

    Both dipyridamole and aspirin are excreted in human milk. Exercise caution when aspirin and extended-release dipyridamole capsules are administered to a nursing woman.

    8.4 Pediatric Use

    Safety and effectiveness of aspirin and extended-release dipyridamole in pediatric patients have not been studied. Due to the aspirin component, use of this product in the pediatric population is not recommended [see Contraindications (4.3)] .

    8.5 Geriatric Use

    Of the total number of subjects in ESPS2, 61 percent were 65 and over, while 27 percent were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology (12.3)] .

    8.6 Patients with Severe Hepatic or Severe Renal Dysfunction

    Aspirin and extended-release dipyridamole has not been studied in patients with hepatic or renal impairment. Avoid using aspirin containing products, such as aspirin and extended-release dipyridamole in patients with severe hepatic or severe renal (glomerular filtration rate < 10 mL/min) dysfunction [see Warnings and Precautions (5.2,5.3) and Clinical Pharmacology (12.3)] .

    10 OVERDOSAGE

    Because of the dose ratio of dipyridamole to aspirin, overdosage of aspirin and extended-release dipyridamole is likely to be dominated by signs and symptoms of dipyridamole overdose. In case of real or suspected overdose, seek medical attention or contact a Poison Control Center immediately. Careful medical management is essential.

    Based upon the known hemodynamic effects of dipyridamole, symptoms such as warm feeling, flushes, sweating, restlessness, feeling of weakness and dizziness may occur. A drop in blood pressure and tachycardia might also be observed.

    Salicylate toxicity may result from acute ingestion (overdose) or chronic intoxication. Severity of aspirin intoxication is determined by measuring the blood salicylate level. The early signs of salicylic overdose (salicylism), including tinnitus (ringing in the ears), occur at plasma concentrations approaching 200 mcg/mL. In severe cases, hyperthermia and hypovolemia are the major immediate threats to life. Plasma concentrations of aspirin above 300 mcg/mL are clearly toxic. Severe toxic effects are associated with levels above 400 mcg/mL. A single lethal dose of aspirin in adults is not known with certainty but death may be expected at 30 g.

    Treatment of overdose consists primarily of supporting vital functions, increasing drug elimination, and correcting acid-base disturbances. Consider gastric emptying and/or lavage as soon as possible after ingestion, even if the patient has vomited spontaneously. After lavage and/or emesis, administration of activated charcoal as a slurry may be beneficial if less than 3 hours have passed since ingestion. Charcoal absorption should not be employed prior to emesis and lavage. Follow acid-base status closely with serial blood gas and serum pH measurements. Maintain fluid and electrolyte balance. Administer replacement fluid intravenously and augment with correction of acidosis. Treatment may require the use of a vasopressor. Infusion of glucose may be required to control hypoglycemia.

    Administration of xanthine derivatives (e.g., aminophylline) may reverse the hemodynamic effects of dipyridamole overdose. Plasma electrolytes and pH should be monitored serially to promote alkaline diuresis of salicylate if renal function is normal. In patients with renal insufficiency or in cases of life-threatening intoxication, dialysis is usually required to treat salicylic overdose; however, since dipyridamole is highly protein bound, dialysis is not likely to remove dipyridamole. Exchange transfusion may be indicated in infants and young children.

    12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The antithrombotic action of aspirin and extended-release dipyridamole is the result of the additive antiplatelet effects of dipyridamole and aspirin.

    Dipyridamole
    Dipyridamole inhibits the uptake of adenosine into platelets, endothelial cells and erythrocytes in vitro and in vivo; the inhibition occurs in a dose-dependent manner at therapeutic concentrations (0.5 to 1.9 mcg/mL). This inhibition results in an increase in local concentrations of adenosine which acts on the platelet A 2-receptor thereby stimulating platelet adenylate cyclase and increasing platelet cyclic-3",5"-adenosine monophosphate (cAMP) levels. Via this mechanism, platelet aggregation is inhibited in response to various stimuli such as platelet activating factor (PAF), collagen and adenosine diphosphate (ADP).

    Dipyridamole inhibits phosphodiesterase (PDE) in various tissues. While the inhibition of cAMP-PDE is weak, therapeutic levels of dipyridamole inhibit cyclic-3",5"guanosine monophosphate-PDE (cGMP-PDE), thereby augmenting the increase in cGMP produced by EDRF (endothelium-derived relaxing factor, now identified as nitric oxide).

    Aspirin
    Aspirin inhibits platelet aggregation by irreversible inhibition of platelet cyclooxygenase and thus inhibits the generation of thromboxane A 2, a powerful inducer of platelet aggregation and vasoconstriction.

    12.2 Pharmacodynamics

    The effect of either agent on the other's inhibition of platelet reactivity has not been evaluated.

    12.3 Pharmacokinetics

    There are no significant interactions between aspirin and dipyridamole. The kinetics of the components are unchanged by their co-administration as aspirin and extended-release dipyridamole.

    Dipyridamole
    Absorption
    Peak plasma levels of dipyridamole are achieved 2 hours (range 1 to 6 hours) after administration of a daily dose of 400 mg aspirin and extended-release dipyridamole (given as 200 mg BID). The peak plasma concentration at steady-state is 1.98 mcg/mL (1.01 to 3.99 mcg/mL) and the steady-state trough concentration is 0.53 mcg/mL (0.18 to 1.01 mcg/mL).

    Effect of Food
    When aspirin and extended-release dipyridamole capsules were taken with a high fat meal, dipyridamole peak plasma levels (C max) and total absorption (AUC) were decreased at steady-state by 20% to 30% compared to fasting. Due to the similar degree of inhibition of adenosine uptake at these plasma concentrations, this food effect is not considered clinically relevant.

    Distribution
    Dipyridamole is highly lipophilic (log P=3.71, pH=7); however, it has been shown that the drug does not cross the blood-brain barrier to any significant extent in animals. The steady-state volume of distribution of dipyridamole is about 92 L. Approximately 99% of dipyridamole is bound to plasma proteins, predominantly to alpha 1-acid glycoprotein and albumin.

    Metabolism and Elimination
    Dipyridamole is metabolized in the liver, primarily by conjugation with glucuronic acid, of which monoglucuronide which has low pharmacodynamic activity is the primary metabolite. In plasma, about 80% of the total amount is present as parent compound and 20% as monoglucuronide. Most of the glucuronide metabolite (about 95%) is excreted via bile into the feces, with some evidence of enterohepatic circulation. Renal excretion of parent compound is negligible and urinary excretion of the glucuronide metabolite is low (about 5%). With intravenous (i.v.) treatment of dipyridamole, a triphasic profile is obtained: a rapid alpha phase, with a half-life of about 3.4 minutes, a beta phase, with a half-life of about 39 minutes, (which, together with the alpha phase accounts for about 70% of the total area under the curve, AUC) and a prolonged elimination phase λz with a half-life of about 15.5 hours. Due to the extended absorption phase of the dipyridamole component, only the terminal phase is apparent from oral treatment with aspirin and extended-release dipyridamole which, in Trial 9.123 was 13.6 hours.

    Special Populations
    Geriatric Patients: In ESPS2 [see Clinical Studies (14)] , plasma concentrations (determined as AUC) of dipyridamole in healthy elderly subjects (>65 years) were about 40% higher than in subjects younger than 55 years receiving treatment with aspirin and extended-release dipyridamole.

    Hepatic Dysfunction: No study has been conducted with aspirin and extended-release dipyridamole in patients with hepatic dysfunction.

    In a study conducted with an intravenous formulation of dipyridamole, patients with mild to severe hepatic insufficiency showed no change in plasma concentrations of dipyridamole but showed an increase in the pharmacologically inactive monoglucuronide metabolite. Dipyridamole can be dosed without restriction as long as there is no evidence of hepatic failure.

    Renal Dysfunction: No study has been conducted with aspirin and extended-release dipyridamole in patients with renal dysfunction.

    In ESPS2 patients [see Clinical Studies (14)] , with creatinine clearances ranging from about 15 mL/min to >100 mL/min, no changes were observed in the pharmacokinetics of dipyridamole or its glucuronide metabolite if data were corrected for differences in age.

    Aspirin
    Absorption
    Peak plasma levels of aspirin are achieved 0.63 hours (0.5 to 1 hour) after administration of a 50 mg aspirin daily dose from aspirin and extended-release dipyridamole (given as 25 mg BID). The peak plasma concentration at steady-state is 319 ng/mL (175 to 463 ng/mL). Aspirin undergoes moderate hydrolysis to salicylic acid in the liver and the gastrointestinal wall, with 50% to 75% of an administered dose reaching the systemic circulation as intact aspirin.

    Effect of Food
    When aspirin and extended-release dipyridamole capsules were taken with a high fat meal, there was no difference for aspirin in AUC at steady-state, and the approximately 50% decrease in C max was not considered clinically relevant based on a similar degree of cyclooxygenase inhibition comparing the fed and fasted state.

    Distribution
    Aspirin is poorly bound to plasma proteins and its apparent volume of distribution is low (10 L). Its metabolite, salicylic acid, is highly bound to plasma proteins, but its binding is concentration-dependent (nonlinear). At low concentrations (<100 mcg/mL), approximately 90% of salicylic acid is bound to albumin. Salicylic acid is widely distributed to all tissues and fluids in the body, including the central nervous system, breast milk and fetal tissues. Early signs of salicylate overdose (salicylism), including tinnitus (ringing in the ears), occur at plasma concentrations approximating 200 mcg/mL [see Adverse Reactions (6) and Overdosage (10)] .

    Metabolism and Elimination
    Aspirin is rapidly hydrolyzed in plasma to salicylic acid, with a half-life of 20 minutes. Plasma levels of aspirin are essentially undetectable 2 to 2.5 hours after dosing and peak salicylic acid concentrations occur 1 hour (range: 0.5 to 2 hours) after administration of aspirin. Salicylic acid is primarily conjugated in the liver to form salicyluric acid, a phenolic glucuronide, an acyl glucuronide and a number of minor metabolites. Salicylate metabolism is saturable and total body clearance decreases at higher serum concentrations due to the limited ability of the liver to form both salicyluric acid and phenolic glucuronide. Following toxic doses (10 to 20 g), the plasma half-life may be increased to over 20 hours.

    The elimination of acetylsalicylic acid follows first-order kinetics with aspirin and extended-release dipyridamole and has a half-life of 0.33 hours. The half-life of salicylic acid is 1.71 hours. Both values correspond well with data from the literature at lower doses which state a resultant half-life of approximately 2 to 3 hours. At higher doses, the elimination of salicylic acid follows zero-order kinetics (i.e., the rate of elimination is constant in relation to plasma concentration), with an apparent half-life of 6 hours or higher. Renal excretion of unchanged drug depends upon urinary pH. As urinary pH rises above 6.5, the renal clearance of free salicylate increases from <5% to >80%. Alkalinization of the urine is a key concept in the management of salicylate overdose [see Overdosage (10)] . Following therapeutic doses, about 10% is excreted as salicylic acid and 75% as salicyluric acid, as the phenolic and acyl glucuronides, in urine.

    Special Populations
    Hepatic Dysfunction: Avoid aspirin in patients with severe hepatic insufficiency.

    Renal Dysfunction: Avoid aspirin in patients with severe renal failure (glomerular filtration rate less than 10 mL/min).

    Aspirin and Extended-release Dipyridamole Capsules
    Drug Interaction
    A dedicated drug interaction study was conducted in 60 healthy volunteers to evaluate the effects of omeprazole 80 mg administered once daily on the pharmacokinetics (PK) of dipyridamole and the pharmacodynamics (PD) of acetylsalicylic acid when co-administered with aspirin and extended-release dipyridamole twice daily. Dipyridamole exposure (C max and AUC) at steady-state were similar with or without omeprazole co-administration. The pharmacokinetics of acetylsalicylic acid was not characterized. However, the antiplatelet activity as measured by arachidonic acid induced platelet aggregation was similar between the treatment arms at steady-state.

    13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis and Mutagenesis and Impairment of Fertility

    In studies in which dipyridamole was administered in the feed to mice (up to 111 weeks in males and females) and rats (up to 128 weeks in males and up to 142 weeks in females), there was no evidence of drug-related carcinogenesis. The highest dose administered in these studies (75 mg/kg/day) was, on a mg/m 2 basis, about equivalent to the maximum recommended daily human oral dose (MRHD) in mice and about twice the MRHD in rats.

    Combinations of dipyridamole and aspirin (1:5 ratio) tested negative in the Ames test, in vivo chromosome aberration tests (in mice and hamsters), oral micronucleus tests (in mice and hamsters) and oral dominant lethal test (in mice). Aspirin, alone, induced chromosome aberrations in cultured human fibroblasts. Mutagenicity tests of dipyridamole alone with bacterial and mammalian cell systems were negative.

    Combinations of dipyridamole and aspirin have not been evaluated for effects on fertility and reproductive performance. There was no evidence of impaired fertility when dipyridamole was administered to male and female rats at oral doses up to 500 mg/kg/day (about 12 times the MRHD on a mg/m 2 basis). A significant reduction in number of corpora lutea with consequent reduction in implantations and live fetuses was, however, observed at 1,250 mg/kg (more than 30 times the MRHD on a mg/m 2 basis). Aspirin inhibits ovulation in rats.

    14 CLINICAL STUDIES

    ESPS2 (European Stroke Prevention Study-2) was a double-blind, placebo-controlled, 24-month study in which 6,602 patients over the age of 18 years had an ischemic stroke (76%) or transient ischemic attack (TIA, 24%) within three months prior to entry. Patients were enrolled in 13 European countries between February 1989 and May 1995 and were randomized to one of four treatment groups: aspirin and extended-release dipyridamole 25 mg/200 mg; extended-release dipyridamole (ER-DP) 200 mg alone; aspirin (ASA) 25 mg alone; or placebo. The mean age in this population was 66.7 years with 58% of them being males. Patients received one capsule twice daily (morning and evening). Efficacy assessments included analyses of stroke (fatal or nonfatal) and death (from all causes) as confirmed by a blinded morbidity and mortality assessment group. There were no differences with regard to efficacy based on age or gender; patients who were older had a trend towards more events.

    Stroke Endpoint
    Aspirin and extended-release dipyridamole reduced the risk of stroke by 22.1% compared to aspirin 50 mg/day alone (p = 0.008) and reduced the risk of stroke by 24.4% compared to extended-release dipyridamole 400 mg/day alone (p = 0.002) (Table 3). Aspirin and extended-release dipyridamole reduced the risk of stroke by 36.8% compared to placebo (p <0.001).

    Over 24 months of Follow-Up

    Figure 1

    Combined Stroke or Death Endpoint
    In ESPS2, aspirin and extended-release dipyridamole reduced the risk of stroke or death by 12.1% compared to aspirin alone and by 10.3% compared to extended-release dipyridamole alone. These results were not statistically significant. Aspirin and extended-release dipyridamole reduced the risk of stroke or death by 24.2% compared to placebo.

    Death Endpoint
    The incidence rate of all-cause mortality was 11.3% for aspirin and extended-release dipyridamole, 11% for aspirin alone, 11.4% for extended-release dipyridamole alone and 12.3% for placebo alone. The differences between the aspirin and extended-release dipyridamole, aspirin alone and extended-release dipyridamole alone treatment groups were not statistically significant. These incidence rates for aspirin and extended-release dipyridamole and aspirin alone are consistent with previous aspirin studies in stroke and TIA patients.

    Patient Information

    Aspirin (AS-pir-in) and Extended-release Dipyridamole (dye-pir-ID-a-mole) Capsules

    Read this Patient Information before you start taking aspirin and extended-release dipyridamole capsules and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

    What are aspirin and extended-release dipyridamole capsules?
    Aspirin and extended-release dipyridamole capsules are a prescription medicine that contains aspirin and a medicine that is slowly released in your body, called dipyridamole. Aspirin and extended-release dipyridamole capsules are used to lower the risk of stroke in people who have had a “mini-stroke” (transient ischemic attack or TIA) or stroke due to a blood clot.

    It is not known if aspirin and extended-release dipyridamole capsules are safe and effective in children. See “Who should not take aspirin and extended-release dipyridamole capsules?”

    Who should not take aspirin and extended-release dipyridamole capsules?
    Do not take aspirin and extended-release dipyridamole capsules if you:

    • are allergic to any of the ingredients in aspirin and extended-release dipyridamole capsules. See the end of this leaflet for a list of ingredients in aspirin and extended-release dipyridamole capsules.
    • are allergic to non-steroidal anti-inflammatory drugs (NSAIDs)
    • have asthma in combination with runny nose and nasal polyps

    Do not give aspirin and extended-release dipyridamole capsules to a child or teenager with a viral illness. Reye syndrome, a life-threatening condition, can happen when aspirin (an ingredient in aspirin and extended-release dipyridamole capsules) is used in children and teenagers who have certain viral illnesses.

    What should I tell my doctor before using aspirin and extended-release dipyridamole capsules?

    Before taking aspirin and extended-release dipyridamole capsules, tell your healthcare provider if you:

    • have stomach ulcers
    • have a history of bleeding problems
    • have heart problems
    • have kidney or liver problems
    • have low blood pressure
    • have myasthenia gravis
    • have any other medical conditions
    • are pregnant or plan to become pregnant. Aspirin and extended-release dipyridamole capsules can harm your unborn baby, especially if you take it in the last (third) trimester of pregnancy. You should not take aspirin and extended-release dipyridamole capsules during pregnancy without first talking to your healthcare provider. Tell your healthcare provider right away if you become pregnant while taking aspirin and extended-release dipyridamole capsules.
    • are breast-feeding or plan to breast-feed. Aspirin and extended-release dipyridamole can pass into your milk and may harm your baby. Talk to your healthcare provider about the best way to feed your baby if you take aspirin and extended-release dipyridamole capsules.

    Tell your doctor about all the medicines you take, including, prescription and non-prescription medicines, vitamins and herbal supplements. Aspirin and extended-release dipyridamole capsules and other medicines may affect each other causing side effects. Aspirin and extended-release dipyridamole capsules may affect the way other medicines work, and other medicines may affect how aspirin and extended-release dipyridamole capsules works.

    Especially tell your healthcare provider if you take:

    • a medicine for high blood pressure, irregular heart beat, or heart failure
    • acetazolamide [Diamox ®]
    • any blood thinner medicines
    • warfarin sodium [Coumadin ®, Jantoven ®]
    • a heparin medicine
    • anagrelide [Agrylin ®]
    • a seizure medicine
    • a medicine for Alzheimer’s disease
    • a water pill
    • methotrexate sodium [Trexall ®]
    • aspirin or a non-steroidal anti-inflammatory drug (NSAIDs). You should not take NSAIDs during treatment with aspirin and extended-release dipyridamole. Using these medicines with aspirin and extended-release dipyridamole capsules can increase your risk of bleeding.
    • a medicine for diabetes
    • probenecid [Probalan ®, Col-Probenecid ®]

    Ask your healthcare provider or pharmacist if you are not sure if your medicine is one that is listed above.

    Know the medicines you take. Keep a list of them and show your healthcare provider and pharmacist when you get a new medicine.
