CONTRAINDICATION Cilostazol and several of its metabolites are inhibitors of phosphodiesterase III. Several drugs with this pharmacologic effect have caused decreased survival compared to placebo in patients with class III-IV congestive heart failure. Cilostazol is contraindicated in patients with congestive heart failure of any severity.

ADVERSE REACTIONS Adverse events were assessed in eight placebo-controlled clinical trials involving 2274 patients exposed to either 50 or 100 mg b.i.d. cilostazol (n = 1301) or placebo (n = 973), with a median treatment duration of 127 days for patients on cilostazol and 134 days for patients on placebo. The only adverse event resulting in discontinuation of therapy in ≥ 3% of patients treated with cilostazol 50 or 100 mg b.i.d. was headache, which occurred with an incidence of 1.3%, 3.5%, and 0.3% in patients treated with cilostazol 50 mg b.i.d., 100 mg b.i.d, or placebo, respectively. Other frequent causes of discontinuation included palpitation and diarrhea, both 1.1% for cilostazol (all doses) versus 0.1% for placebo. The most commonly reported adverse events, occurring in ≥ 2% of patients treated with cilostazol 50 or 100 mg b.i.d., are shown in the table (below). Other events seen with an incidence of ≥ 2%, but occurring in the placebo group at least as frequently as in the 100 mg b.i.d. group were: asthenia, hypertension, vomiting, leg cramps, hyperesthesia, paresthesia, dyspnea, rash, hematuria, urinary tract infection, flu syndrome, angina pectoris, arthritis, and bronchitis. Most Commonly Reported AEs (Incidence ≥ 2%) in Patients on Cilostazol 50 mg b.i.d. or 100 mg b.i.d. and Occurring at a Rate in the 100 mg b.i.d. Group Higher Than in Patients on Placebo Adverse Events (AEs) by Body System Cilostazol 50 mg b.i.d. (N = 303) % Cilostazol 100 mg b.i.d.

Body as a whole: Chills, face edema, fever, generalized edema, malaise, neck rigidity, pelvic pain, retroperitoneal hemorrhage.

Digestive: Anorexia, cholelithiasis, colitis, duodenal ulcer, duodenitis, esophageal hemorrhage, esophagitis, increased GGT, gastritis, gastroenteritis, gum hemorrhage, hematemesis, melena, peptic ulcer, periodontal abscess, rectal hemorrhage, stomach ulcer, tongue edema. Endocrine: Diabetes mellitus. Hemic and Lymphatic: Anemia, ecchymosis, iron deficiency anemia, polycythemia, purpura. Metabolic and Nutritional: Increased creatinine, gout, hyperlipemia, hyperuricemia. Musculoskeletal: Arthralgia, bone pain, bursitis. Nervous: Anxiety, insomnia, neuralgia. Respiratory: Asthma, epistaxis, hemoptysis, pneumonia, sinusitis. Skin and Appendages: Dry skin, furunculosis, skin hypertrophy, urticaria. Special Senses: Amblyopia, blindness, conjunctivitis, diplopia, ear pain, eye hemorrhage, retinal hemorrhage, tinnitus. Urogenital: Albuminuria, cystitis, urinary frequency, vaginal hemorrhage, vaginitis. Postmarketing Experience The following events have been reported spontaneously from worldwide postmarketing experience since launch of cilostazol in the U.S. Blood and lymphatic system disorders: Agranulocytosis, aplastic anemia, granulocytopenia, thrombocytopenia, leukopenia, bleeding tendency Cardiac disorders: Torsade de pointes, QTc prolongation ( t orsade de pointes and QTc prolongation occurred in patients with cardiac disorders, e.g., complete atrioventricular block, cardiac failure and bradyarrythmia, when treated with cilostazol. Cilostazol was used “off label” due to its positive chronotropic action ) Gastrointestinal disorders: Gastrointestinal hemorrhage General disorders and administration site conditions: Pain, chest pain, hot flushes Hepatobiliary disorders: Hepatic dysfunction/abnormal liver function tests, jaundice Injury, poisoning and procedural complications: Extradural hematoma and subdural hematoma Investigations: Blood glucose increased, blood uric acid increased, platelet count decreased, white blood cell count decreased, increase in BUN (blood urea increased), blood pressure increase Nervous system disorders: Intracranial hemorrhage, cerebral hemorrhage, cerebrovascular accident Respiratory, thoracic and mediastinal disorders: Pulmonary hemorrhage, interstitial pneumonia Skin and subcutaneous tissue disorders: Hemorrhage subcutaneous, pruritus, skin eruptions including Stevens-Johnson syndrome, skin drug eruption (dermatitis medicamentosa) Vascular disorders: Subacute thrombosis (these cases of subacute thrombosis occurred in patients treated with aspirin and “off label” use of cilostazol for prevention of thrombotic complication after coronary stenting)
