CILOSTAZOL (Page 2 of 2)

Inhibitors of CYP3A4

Strong Inhibitors of CYP3A4: A priming dose of ketoconazole 400 mg (a strong inhibitor of CYP3A4), was given one day prior to coadministration of single doses of ketoconazole 400 mg and cilostazol 100 mg. This regimen increased cilostazol Cmax by 94% and AUC by 117%. Other strong inhibitors of CYP3A4, such as itraconazole, fluconazole, miconazole, fluvoxamine, fluoxetine, nefazodone, and sertraline, would be expected to have a similar effect (see DOSAGE AND ADMINISTRATION).

Moderate Inhibitors of CYP3A4:

  1. Erythromycin and other macrolide antibiotics: Erythromycin is a moderately strong inhibitor of CYP3A4. Coadministration of erythromycin 500 mg q 8h with a single dose of cilostazol 100 mg increased cilostazol Cmax by 47% and AUC by 73%. Inhibition of cilostazol metabolism by erythromycin increased the AUC of 4´-trans-hydroxy-cilostazol by 141%. Other macrolide antibiotics (e.g., clarithromycin), but not all (e.g., azithromycin), would be expected to have a similar effect (see DOSAGE AND ADMINISTRATION).
  2. Diltiazem: Diltiazem 180 mg decreased the clearance of cilostazol by ∼30%. Cilostazol Cmax increased ∼30% and AUC increased ∼40% (see DOSAGE AND ADMINISTRATION).
  3. Grapefruit Juice: Grapefruit juice increased the Cmax of cilostazol by ∼50%, but had no effect on AUC.

Inhibitors of CYP2C19: Omeprazole: Coadministration of omeprazole did not significantly affect the metabolism of cilostazol, but the systemic exposure of 3,4-dehydro-cilostazol was increased by 69%, probably the result of omeprazole’s potent inhibition of CYP2C19 (see DOSAGE AND ADMINISTRATION).

Quinidine: Concomitant administration of quinidine with a single dose of cilostazol 100 mg did not alter cilostazol pharmacokinetics.

Lovastatin: The concomitant administration of lovastatin with cilostazol decreases cilostazol Css, max and AUCτ by 15%. There is also a decrease, although nonsignificant, in cilostazol metabolite concentrations. Coadministration of cilostazol with lovastatin increases lovastatin and β-hydroxi lovastatin AUC approximately 70%. This is most likely clinically insignificant.

CLINICAL STUDIES:

The ability of cilostazol to improve walking distance in patients with stable intermittent claudication was studied in eight large, randomized, placebo-controlled, double-blind trials of 12 to 24 weeks’ duration using dosages of 50 mg b.i.d. (n=303), 100 mg b.i.d. (n=998), and placebo (n=973). Efficacy was determined primarily by the change in maximal walking distance from baseline (compared to change on placebo) on one of several standardized exercise treadmill tests.

Compared to patients treated with placebo, patients treated with cilostazol tablets 50 or 100 mg b.i.d. experienced statistically significant improvements in walking distances both for the distance before the onset of claudication pain and the distance before exercise-limiting symptoms supervened (maximal walking distance). The effect of cilostazol on walking distance was seen as early as the first on-therapy observation point of two or four weeks.

The following figure depicts the percent mean improvement in maximal walking distance at study end for each of the eight studies.

Across the eight clinical trials, the range of improvement in maximal walking distance in patients treated with cilostazol 100 mg b.i.d., expressed as the percent mean change from baseline, was 28% to 100%.

The corresponding changes in the placebo group were –10% to 41%.

The Walking Impairment Questionnaire, which was administered in six of the eight clinical trials, assesses the impact of a therapeutic intervention on walking ability. In a pooled analysis of the six trials, patients treated with either cilostazol 100 mg b.i.d. or 50 mg b.i.d. reported improvements in their walking speed and walking distance as compared to placebo. Improvements in walking performance were seen in the various subpopulations evaluated, including those defined by gender, smoking status, diabetes mellitus, duration of peripheral artery disease, age, and concomitant use of beta blockers or of calcium channel blockers. Cilostazol has not been studied in patients with rapidly progressing claudication or in patients with leg pain at rest, ischemic leg ulcers, or gangrene. Its long-term effects on limb preservation and hospitalization have not been evaluated.

A randomized, double-blind, placebo-controlled Phase IV study was conducted to assess the long-term effects of cilostazol, with respect to mortality and safety, in 1,439 patients with the intermittent claudication and no heart failure. The trial stopped early due to enrollment difficulties and a lower than expected overall death rate. With respect to mortality, the observed 36-month Kaplan-Meier event rate for deaths on study drug with a median time of 18 months was 5.6% ( 95% CI of 2.8 to 8.4%) on cilostazol and 6.8%( 95% CI of 1.9 to 11.5%) on placebo. These data appear to be sufficient to exclude a 75% increase in the risk of mortality on cilostazol, which s the a priori study hypothesis.

INDICATIONS AND USAGE

Cilostazol tablets are indicated for the reduction of symptoms of intermittent claudication, as indicated by an increased walking distance.

CONTRAINDICATIONS

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 tablets are contraindicated in patients with congestive heart failure of any severity.

Cilostazol tablets are contraindicated in patients with haemostatic disorders or active pathologic bleeding, such as bleeding peptic ulcer and intracranial bleeding. Cilostazol tablets inhibit platelet aggregation in a reversible manner.

Cilostazol tablets are contraindicated in patients with known or suspected hypersensitivity to any of its components.

PRECAUTIONS

Hematologic adverse reactions:
Rare cases have been reported of thrombocytopenia or leucopenia progressing to agranulocytosis when cilostazol was not immediately discontinued. The agranulocytosis, however, was reversible on discontinuation of Cilostazol.

Use with Clopidogrel:
There is limited information with respect to the efficacy or safety of the concurrent use of cilostazol and clopidogrel, a platelet-aggregation inhibiting drug indicated for use in patients with peripheral arterial disease. Although it cannot be determined whether there was an additive effect on bleeding times during concomitant administration with cilostazol and clopidogrel, caution is advised for checking bleeding times during coadministration.

Information for Patients:
Please refer to the patient package insert.
Patients should be advised:

  • to read the patient package insert for cilostazol carefully before starting therapy and to reread it each time therapy is renewed in case the information has changed.
  • to take cilostazol at least one-half hour before or two hours after food.
  • that the beneficial effects of cilostazol on the symptoms of intermittent claudication may not be immediate. Although the patient may experience benefit in 2 to 4 weeks after initiation of therapy, treatment for up to 12 weeks may be required before a beneficial effect is experienced.

Hepatic Impairment:
Patients with moderate or severe hepatic impairment have not been studied in clinical trials.

Special caution is advised when cilostazol is used in such patients.

Renal Impairment:
Patients on dialysis have not been studied, but, it is unlikely that cilostazol can be removed efficiently by dialysis because of its high protein binding (95-98%).

Special caution is advised when cilostazol is used in patients with severe renal impairment; estimated creatinine clearence, <25 ml/min.

Drug Interactions:
Since cilostazol is extensively metabolized by cytochrome P-450 isoenzymes, caution should be exercised when cilostazol is coadministered with inhibitors of CYP3A4 such as ketoconazole and erythromycin or inhibitors of CYP2C19 such as omeprazole. Pharmacokinetic studies have demonstrated that omeprazole and erythromycin significantly increased the systemic exposure of cilostazol and/or its major metabolites. Population pharmacokinetic studies showed higher concentrations of cilostazol among patients concurrently treated with diltiazem, an inhibitor of CYP3A4 (see CLINICAL PHARMACOLOGY, Pharmacokinetic and Pharmacodynamic Drug-Drug Interactions). Cilostazol does not, however, appear to cause increased blood levels of drugs metabolized by CYP3A4, as it had no effect on lovastatin, a drug with metabolism very sensitive to CYP3A4 inhibition.

Use with other anitplatelet agents:
Cilostazol inhibits platelet aggregation but in a reversible manner. Caution is advised in patients at risk of bleeding from surgery or pathologic processes. Platelet aggregability returns to normal within 96 hours of stopping cilostazol. Caution is advised in patients receiving both cilostazol and any other antiplatelet agent, or in patients with thrombocytopenia.

Cardiovascular Toxicity:
Repeated oral administration of cilostazol to dogs (30 or more mg/kg/day for 52 weeks, 150 or more mg/kg/day for 13 weeks, and 450 mg/kg/day for 2 weeks), produced cardiovascular lesions that included endocardial hemorrhage, hemosiderin deposition and fibrosis in the left ventricle, hemorrhage in the right atrial wall, hemorrhage and necrosis of the smooth muscle in the wall of the coronary artery, intimal thickening of the coronary artery, and coronary arteritis and periarteritis. At the lowest dose associated with cardiovascular lesions in the 52-week study, systemic exposure (AUC) to unbound cilostazol was less than that seen in humans at the maximum recommended human dose (MRHD) of 100 mg b.i.d. Similar lesions have been reported in dogs following the administration of other positive inotropic agents (including PDE III inhibitors) and/or vasodilating agents. No cardiovascular lesions were seen in rats following 5 or 13 weeks of administration of cilostazol at doses up to 1500 mg/kg/day. At this dose, systemic exposures (AUCs) to unbound cilostazol were only about 1.5 and 5 times (male and female rats, respectively) the exposure seen in humans at the MRHD. Cardiovascular lesions were also not seen in rats following 52 weeks of administration of cilostazol at doses up to 150 mg/kg/day. At this dose, systemic exposures (AUCs) to unbound cilostazol were about 0.5 and 5 times (male and female rats, respectively) the exposure in humans at the MRHD. In female rats, cilostazol AUCs were similar at 150 and 1500 mg/kg/day. Cardiovascular lesions were also not observed in monkeys after oral administration of cilostazol for 13 weeks at doses up to 1800 mg/kg/day. While this dose of cilostazol produced pharmacologic effects in monkeys, plasma cilostazol levels were less than those seen in humans given the MRHD, and those seen in dogs given doses associated with cardiovascular lesions.

Carcinogenesis, Mutagenesis, Impairment of Fertility:
Dietary administration of cilostazol to male and female rats and mice for up to 104 weeks, at doses up to 500 mg/kg/day in rats and 1000 mg/kg/day in mice, revealed no evidence of carcinogenic potential. The maximum doses administered in both rat and mouse studies were, on a systemic exposure basis, less than the human exposure at the MRHD of the drug. Cilostazol tested negative in bacterial gene mutation, bacterial DNA repair, mammalian cell gene mutation, and mouse in vivo bone marrow chromosomal aberration assays. It was, however, associated with a significant increase in chromosomal aberrations in the in vitro Chinese Hamster Ovary Cell assay.

Cilostazol did not affect fertility or mating performance of male and female rats at doses as high as 1000 mg/kg/day. At this dose, systemic exposures (AUCs) to unbound cilostazol were less than 1.5 times in males, and about 5 times in females, the exposure in humans at the MRHD.

Pregnancy:
Pregnancy Category C: In a rat developmental toxicity study, oral administration of 1000 mg cilostazol/kg/day was associated with decreased fetal weights, and increased incidences of cardiovascular, renal, and skeletal anomalies (ventricular septal, aortic arch, and subclavian artery abnormalities, renal pelvic dilation, 14th rib, and retarded ossification). At this dose, systemic exposure to unbound cilostazol in nonpregnant rats was about 5 times the exposure in humans given the MRHD. Increased incidences of ventricular septal defect and retarded ossification were also noted at 150 mg/kg/day (5 times the MRHD on a systemic exposure basis). In a rabbit developmental toxicity study, an increased incidence of retardation of ossification of the sternum was seen at doses as low as 150 mg/kg/day. In nonpregnant rabbits given 150 mg/kg/day, exposure to unbound cilostazol was considerably lower than that seen in humans given the MRHD, and exposure to 3,4-dehydro-cilostazol was barely detectable.

When cilostazol was administered to rats during late pregnancy and lactation, an increased incidence of stillborn and decreased birth weights of offspring was seen at doses of 150 mg/kg/day (5 times the MRHD on a systemic exposure basis).

There are no adequate and well-controlled studies in pregnant women.

Nursing Mothers:
Transfer of cilostazol into milk has been reported in experimental animals (rats). Because of the potential risk to nursing infants, a decision should be made to discontinue nursing or to discontinue cilostazol.

Pediatric Use:
The safety and effectiveness of cilostazol in pediatric patients have not been established.

Geriatric Use:
Of the total number of subjects (n = 2274) in clinical studies of cilostazol, 56 percent were 65-years-old and over, while 16 percent were 75-years-old 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. Pharmacokinetic studies have not disclosed any age-related effects on the absorption, distribution, metabolism, and elimination of cilostazol and its metabolites.

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 tablets (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.

The following adverse events have been reported spontaneously from worldwide post-marketing experience since launch of cilostazol in the US.

  • Blood and lymphatic system disorders:
    agranulocytosis, aplastic anemia, granulocytopenia, thrombocytopenia, leukopenia, bleeding tendency
  • Cardiac disorders:
    Torsades de pointes, QTc prolongation (Torsades 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

    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.)

OVERDOSAGE
Information on acute overdosage with cilostazol in humans is limited. The signs and symptoms of an acute overdose can be anticipated to be those of excessive pharmacologic effect: severe headache, diarrhea, hypotension, tachycardia, and possibly cardiac arrhythmias. The patient should be carefully observed and given supportive treatment. Since cilostazol is highly protein-bound, it is unlikely that it can be efficiently removed by hemodialysis or peritoneal dialysis. The oral LD50 of cilostazol is >5.0 g/kg in mice and rats and >2.0 g/kg in dogs.

DOSAGE AND ADMINISTRATION
The recommended dosage of cilostazol is 100 mg b.i.d. taken at least half an hour before or two hours after breakfast and dinner. A dose of 50 mg b.i.d. should be considered during coadministration of such inhibitors of CYP3A4 as ketoconazole, itraconazole, erythromycin and diltiazem, and during coadministration of such inhibitors of CYP2C19 as omeprazole.

Patients may respond as early as 2 to 4 weeks after the initiation of therapy, but treatment for up to 12 weeks may be needed before a beneficial effect is experienced.

Discontinuation of Therapy: The available data suggest that the dosage of cilostazol can be reduced or discontinued without rebound (i.e., platelet hyperaggregability).

Cilostazol Tablets 50 mg and 100 mg

Patient Information about cilostazol (sil-OS-tah-zol)

Please read this leaflet before you start taking cilostazol and each time you renew it in case anything has changed. This leaflet does not replace careful discussions with your doctor. You and your doctor should discuss cilostazol when you start taking it and at regular check-ups. You should follow your doctor’s advice about when to have check-ups.

What is cilostazol for?

Cilostazol may improve the symptoms of patients with a medical condition called intermittent claudication.

What is intermittent claudication?

Intermittent claudication is pain in the legs that occurs with walking and disappears with rest. It occurs because narrowing or blockage of the arteries decreases blood flow to the legs. The decreased blood flow does not supply enough oxygen to the leg muscles during walking, resulting in these painful leg cramps.

What treatments are available for intermittent claudication?

The three main treatments available for intermittent claudication are:

  • Exercise. Your doctor may advise an exercise program.
  • Medication. Your doctor may prescribe a medication such as cilostazol. (See Who should not take cilostazol?)
  • Surgery. Your doctor may recommend a surgical procedure to bypass the blocked segment of the artery. Another procedure is called a percutaneous transluminal angioplasty. In this procedure, a catheter (a flexible tube) is inserted into the artery to reduce the blockage and improve blood flow.

How does cilostazol work?

  • The exact way that many drugs work is not well understood. Although how cilostazol works is not completely clear, its main effects are to dilate (widen) the arteries supplying blood to the legs and to decrease the ability of platelets in the blood to stick together. Platelets are particles that circulate in the blood and play a role in clotting.
  • Cilostazol may reduce the leg pain that patients with intermittent claudication experience, allowing them to walk farther before their leg pain occurs.
  • Improvement in symptoms may occur as soon as 2 weeks, but could take up to 12 weeks. If you have not noticed any benefit from cilostazol after 12 weeks you and your doctor may wish to discuss other forms of treatment.
  • Sometimes blood vessel disease of the legs causes pain at rest or breakdown of skin in the leg. Cilostazol has not been shown to work in patients with these problems.

Who should not take cilostazol?

  • Patients who have congestive heart failure (CHF) must not take cilostazol.
    The most common symptoms of CHF are shortness of breath and swelling of the legs. However, other conditions may also cause these symptoms.
  • Patients who have bleeding problems, such as a bleeding peptic ulcer, must not take cilostazol.
    Cilostazol decreases the ability of blood particles, called platelets, to stick together and this can increase the risk of bleeding. It is important that you discuss with your doctor whether you have CHF or bleeding problems.
  • Over 1,300 patients took cilostazol in studies that lasted for 3 to 6 months. The mortality rate in these patients was similar to placebo (less than 1%). These studies were too small to be sure there is not some increased risk of dying with longer use or in patients sicker than those in the studies.

How should cilostazol be taken?

  • Follow your doctor’s advice about how to take cilostazol.
  • You should take cilostazol twice a day, at least one half-hour before or two hours after breakfast and dinner. Take cilostazol at about the same times each day.
  • Do not share cilostazol with anyone else. It was prescribed only for you.
  • Keep cilostazol and all drugs out of the reach of children.

Can cilostazol be taken with other drugs?

Certain drugs and foods can increase the amount of cilostazol in the blood. Because of this, your doctor may adjust your dose of cilostazol or even stop it if you are taking or are going to take one of the following medications.

Drugs Interacting With Cilostazol
Generic Name (Brand Name) Type of Drug
erythromycin (such as E.E.S.® , Erythrocin®) Antibiotic
ketoconazole (Nizoral®), itraconazole (Sporanox®) Antifungal
diltiazem (Cardizem®) Antihypertensive
omeprazole (Prilosec®) Gastric acid reducer

This list does not include every drug that may interact with cilostazol. Therefore, you should tell your doctor about all medications that you are taking, including vitamins, herbal supplements and over-the-counter drugs you can buy without a prescription. You should also check with your doctor before taking a new medication after you have begun cilostazol.

What are the possible side effects of cilostazol?

Cilostazol may cause side effects including headache, diarrhea, abnormal stools, increased heart rate, and palpitations.

You should discuss possible side effects with your doctor before taking cilostazol and any time you think you are having a side effect.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

This provides only a summary of information about cilostazol. If you have any questions about cilostazol, talk to your doctor.
