Mier SIUUUIY, Accourm nWcti ra« FUU Husammc iwowunow. Sit PKOfllSIONAl INFORMATION ACCOLATE twice a day helps me control my asthma. ACCOLATE® (zafirlwkast) isn't just another medication, it's a new type of asthma therapy. ACCOLATE is an oral tablet available only by prescription, for the prevention and chronic treatment of asthma in adults and children 12 years of age and older. ACCOLAFE doesn't just treat your symptoms; it targets a cause - leukotrienes. ACCOLATE isn't a steroid or a theophylline. The way ACCOLATE works is simple, in people with asthma, the body produces natural chemicals known as leukotrienes. These lewkotrienes cause the muscles in the airways to contract and lung tissue to swell, resulting in difficulty breathing. Taken regularly, ACCOLATE can actually block the effects of these chemicals. The result? Improvement in your asthma condition reflected in fewer daytime symptoms and less frequent nighttime awakenings. ACCOLATE should not be used to treat an acute asthma attack. With ACCOLATE, you simply take one tablet in the morning, another in the evening - an hour before or two hours after eating. Improvement in symptoms usually occurs within one week of starting treatment fe Ask your doctor if ACCOLATE is right for you. As with all medicines, talk to your doctor before stopping or decreasing other medications. in over 4,000 people studied, ACCOLATE was generally well tolerated. 1 The most common side effects include headache, infection, 2 and nausea. Women who are breast-feeding should not take ACCOLATE, as the drug may be excreted through breast milk. Patients on oral warfarin therapy and ACCOLATE should have their pro- thrombin times monitored and anticoagulant dose adjusted accordingly. ACCOLATE is a simple, convenient way to help control asthma. So talk to your doctor. Please see important information on the right. ORAL, Att. ORAL, COLATE* ZAFIRLUKASTffi!

Infections were associated with coadministration of inhaled corticosteroids. The clinical significance of this finding is unknown.

ACCOLATE is not Indicated for use in the revmal ofbronchospasm In acute asthma attack], Including status asthmatlcus. Therapy wift ACCOLATE can be continued during acute exacerbations of asthma. Coadministration of zoflrtukast with warfarin results In a clinically significant Increase in pratrrrombin time (PT). Patients on oral warfarin anticoagulant therapy and ACCOLATE should have their prothrombln times monitored closely and anticoagulant dose adjusted accordingly. (See PRECAUTIONS, Drug Interactions.) MKMmOM >»iinjsUlll *r KsUnHJ ACCOLATE Is Indicated for the chronic treatment of asthma and should be taken regularly as prescribed, even during symptom-free periods. ACCOLATE Is not a bronchodilator and should not be used to treat acute episodes of asthma, patients receiving ACCOLATE should be Instructed not to decrease the dose or stop taking ory other antiasthma medication unless Instructed by a physician, women who are breastfeeding should be instructed not to take ACCOLATE (see PRECAUTIONS. Nursing Mothers). Alternative antiosthma medication should be considered In such patients. The UcmatlaUHty of ACCOLATE may be decreased when taken with food. Patients should be instructed to take ACCOLATE at least l hour before or 2 hours after meals. OHM MncttoK In a drug Interaction study m 16 healthy male volunteers, coadministration of multiple doses of zafWukast (160 mg/day) to steady state with a single 25-mg dose of warfarin resulted In a significant Increase In the mean AUC (* 63\) and halHife (»36!»l of S-warfarin.

AS ACCOLATE Is known to be an inhibitor of OP 3*4 in vitro. It is reasonable to employ appropriate dinical monitoring when these drugs are coodminlstered with ACCOLATE. In a drug interaction study in n asthmatic patients, coadmlrwtrauon of a single dose of zafirlukast (40 mg) with erythromycfn (500 mg three times aairy |br 5 days) to steady state resulted in decreased mean plasma levels of zafirlukast by approximately 40S due to a decrease In zafiriukast btovaikibilrly Coadministration of zafirlukast (80 jnolQofl at steady stale with a single (6 mg/kg) in 13 asthmatic patients resulted In decreased mean plasma levels of zajlnukast by approximately 30*. but no eject on plasma theopnytlne levels was observed. coadministration of zaflrlukast (40 mo/doy) with aspirin (6SO mg four times dairy) resulted In mean Increased plasma levels of zafirlukast by appraximatery4S!«. in a sinoitMnd, ponniekiroup, 3-wet* study in gheartby (em* subjects taking, oral contraceptive, 40 mg twice dairy of jorlrluluut had no slanifl- ' - ' ethlrr/l estrvdiol plasma r ccncweiitlut e|kacy: c«rcl»f»Mli, MvcMtmiii, mtulriiieirT sjf ftitWty: inlwo-year cartJnogenlcity studies, zufiriukast was aoMnrsund at oral dairy doses of K), 100. and 300 maM to mice arid 40, 400, aru 2000 mg/kg to rats.

The clinical significance of these findings for the long-term use of ACCOLATE is unknown. In mutaaenicity studies, there was no evidence of mutogenkT potential In reverse (5. typhlmurium and E. coll) or forward point mutation (CHO-HCPRT ana! mouse lymphonw) assays or in two assays for chromosomal aberrations (human peripheral blood rymphocyte clastogenlc assay and the rat bone marrow mkronucleus assay). rleproducdon and fertility studies In mB showed no effect on fertility due to zafirfukost at doses up to 2000 ma/kg (approximately 400 times the maximum recommended human dairy oral dose on mj/m'basis), in tne one-year toxicity studies In dogs, zafirlukast produced on increase In absolute and relative uterine and ovarian weights at an oral dose of ISO mg/kg. resultingTn appmfmatery is times the systemic exposure (AUC o.,ji.) in humans at the maximum recommended human oral dairy dose, frtf rwncy cnuory I: NO terato- genicity was observed at oral doses up n 1«B mo/kg/doy in mice (approximately 160 times the maximum recommended human dairy oral dose on a majnf basis), 2000 mg/kg/day in rats (approximately 400 times the maximum recommended human dairy oral dose on a mg/m 1 basis) and 2000 mg/kj/day In cynomolgus monkeys (opproumotely «oo times the maximum recommended human dally oral dose on a mg/m' basis).

The safety database for ACCOLATE consists of more than 4000 healthy volunteers and patients who received ACCOLATE, of which 172] were asthmatics enrolled In trials of 13 weeks duration or longer. A total of 671 patients received ACCOLATE for l year or longer. The majority of the patient! were 18 years of age or older; however. 222 patients between the age of 12 and 18 years received ACCOLATE.
