Acetaminophen (4'-hydroxyacetanilide), a slightly bitter, white, odorless, crystalline powder, is a non-opiate, non-salicylate analgesic and antipyretic.

It has the following structural formula:

Caffeine (1,3,7-trimethylxanthine), a bitter, white crystalline powder, is a central nervous system stimulant. It has the following structural formula:

Dihydrocodeine Bitartrate (4,5a-epoxy-3-methoxy-17-methylmDihydrocodeine Bitartrate (4,5a-epoxy-3-methoxy-17-methylmDihydrocodeine Bitartrate (4,5a-epoxy-3-methoxy-17-methylmDihydrocodeine Bitartrate (4,5a-epoxy-3-methoxy-17-methylmorphinan-6a-ol (+)-tartrate), an odorless, fine white powder is an opioid analgesic. It has the following structural formula:

In addition, each tablet also contains the following inactive ingredients: crospovidone, magnesium stearate, microcrystalline cellulose, povidone, pregelatinized starch, stearic acid.

Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets contain dihydrocodeine which is a semisynthetic narcotic analgesic related to codeine, with multiple actions qualitatively similar to those of codeine; the most prominent of these involve the central nervous system and organs with smooth muscle components. The principal action of therapeutic value is analgesia.

This combination product also contains acetaminophen, a non-opiate, non-salicylate analgesic and antipyretic. This combination product contains caffeine as an analgesic adjuvant. Caffeine is also a central nervous system and cardiovascular stimulant.

Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets are indicated for the relief of moderate to moderately severe pain.

This combination product is contraindicated in persons with hypersensitivity to dihydrocodeine, codeine, acetaminophen, caffeine, or any of the inactive components listed above, or any situation where opioids are contraindicated including significant respiratory depression (in unmonitored settings or in the absence of resuscitative equipment), acute or severe bronchial asthma or hypercapnia, and paralytic ileus.

Dihydrocodeine:

The most frequently observed adverse reactions include light-headedness, dizziness, drowsiness, headache, fatigue, sedation, sweating, nausea, vomiting, constipation, pruritus, and skin reactions. With the exception of constipation, tolerance develops to most of these effects. Other reactions that have been observed with dihydrocodeine or other opioids include respiratory depression, orthostatic hypotension, cough suppression, confusion, diarrhea, miosis, abdominal pain, dry mouth, indigestion, anorexia, spasm of biliary tract, and urinary retention. Physical and psychological dependence are possibilities. Hypersensitivity reactions (including anaphylactoid reactions), hallucinations, vivid dreams, granulomatous interstitial nephritis, severe narcosis and acute renal failure have been reported rarely during dihydrocodeine administration.

Acetaminophen:

Acetaminophen in therapeutic doses rarely causes adverse reactions.

The most serious adverse reaction is hepatoxicity from overdosage (see OVERDOSAGE). Thrombocytopenia, leukopenia, pancytopenia, neutropenia, thrombocytopenic purpura, and agranulocytosis have been reported in patients receiving acetaminophen or p-aminophenol derivatives. Hypersensitivity reactions including urticarial or erythematous skin reactions, laryngeal edema, angioedema, or anaphylactoid reactions are rare.

Caffeine:

Adverse reactions associated with caffeine use include anxiety, anxiety neurosis, excitement, headaches, insomnia, irritability, lightheadedness, restlessness, tenseness, tremor, extrasystoles, palpitations, tachycardia, diarrhea, nausea, stomach pain, vomiting, diuresis, urticarcia, scintillating scotoma, and tinnitus.

This combination product is subject to the provisions of the Controlled Substance Act, and has been placed in Schedule III.

Dihydrocodeine can produce drug dependence of the codeine type and therefore has the potential of being abused.

Like other opioid analgesics, dihydrocodeine may produce subjective effects other than analgesia (e.g., euphoria, relaxation), which may contribute to abuse by some patients. Psychological dependence, physical dependence, and tolerance may develop upon repeated administration of dihydrocodeine, and It should be prescribed and administered with the same degree of caution appropriate to the use of other oral opioid analgesic medications.

Symptoms of dihydrocodeine withdrawal consist of irritability, restlessness, insomnia, diaphoresis, anxiety and palpitations.

Prolonged, high intake of caffeine may produce tolerance and habituation. Physical signs of withdrawal, such as headaches, irritation, nervousness, anxiety, and dizziness may occur upon abrupt discontinuation.

Following an acute overdosage with Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets, toxicity may result from the dihydrocodeine, acetaminophen, or, less likely, caffeine component. An overdose is a potentially lethal polydrug overdose situation, and consultation with a regional poison control center is recommended. A listing of the poison control centers can be found in standard references such as the Physician's Desk Reference®.

Signs and Symptoms and Laboratory Findings:

Toxicity from dihydrocodeine is typical of opioids and includes pinpoint pupils, respiratory depression, and loss of consciousness. Convulsions, cardiovascular collapse, and death may occur. A single case of acute rhabdomyolysis associated with an overdose of dihydrocodeine has been reported. With acetaminophen, dose-dependent potentially fatal hepatic necrosis is the most serious adverse effect. Renal tubular necrosis, hypoglycemic coma, and thrombocytopenia may occur. Early symptoms of hepatotoxicity include nausea, vomiting, diaphoresis, and general malaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours after ingestion. Acute caffeine poisoning may cause insomnia, restlessness, tremor, delirium, tachycardia, extrasystoles, and seizures.

Because overdose information on this combination product is limited, it is unclear which of the signs and symptoms of toxicity would manifest in any particular overdose situation.

Treatment:

Immediate treatment of an overdosage of Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets includes support of cardiorespiratory function and measures to reduce drug absorption. Vomiting should be induced with syrup of ipecac, if the patient is alert and has adequate laryngeal reflexes. Oral activated charcoal should follow. The first dose of charcoal should be accompanied by an appropriate cathartic. Gastric lavage may be necessary. Hypotension is usually hypovolemic and should be treated with fluids. Endotracheal intubation and artificial respiration may be necessary. Peritoneal or hemodialysis may be necessary. If hypoprothrombinemia occurs, Vitamin K should be administered.

A pure opioid antagonist, such as naloxone or nalmefene, is a specific antidote against respiratory depression which results from opioid overdose. Opioid antagonists should not be given in the absence of clinically significant respiratory or circulatory depression secondary to opioid overdose. They should be administered cautiously to persons who are known, or suspected to be, physically dependent on any opioid agonist including Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets. In such cases, an abrupt or complete reversal of opioid effects may precipitate an acute abstinence syndrome. The prescribing information for the specific opioid antagonist should be consulted for details of their proper use.

In adults and adolescents, regardless of the quantity of acetaminophen reported to have been ingested, acetylcysteine should be administered immediately if 24 hours or less have elapsed from the reported time of ingestion. It is not advisable to await the plasma concentration determination of acetaminophen before administering acetylcysteine. Serum liver enzyme levels should be measured. Therapy in children involves a similar treatment scheme; however, a regional Poison Control Center should be contacted. No specific antidote is available for caffeine. In addition to the supportive measures above, administration of demulcents such as aluminum hydroxide gel may diminish gastrointestinal irritation. Seizures may be treated with intravenous diazepam or a barbiturate.

The usual adult dosage is one (1) Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets orally every four (4) hours, as needed. Dosage should be adjusted according to the severity of the pain and the response of the patient. No more than one (1) tablet should be taken in a 4-hour period. No more than five (5) doses, or five (5) tablets should be taken in a 24-hour period.
