Spiriva Respimat

1 INDICATIONS AND USAGE SPIRIVA RESPIMAT is an anticholinergic indicated for: The long-term, once-daily, maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), and for reducing COPD exacerbations ( 1.1 ) The long-term, once-daily, maintenance treatment of asthma in patients 6 years of age and older ( 1.2 ) Limitation of Use: Not indicated for relief of acute bronchospasm ( 1.1 , 1.2 , 5.1 ) 1.1 Maintenance Treatment of Chronic Obstructive Pulmonary Disease SPIRIVA RESPIMAT (tiotropium bromide) is indicated for the long-term, once-daily, maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. SPIRIVA RESPIMAT is indicated to reduce exacerbations in COPD patients. Important Limitation of Use: SPIRIVA RESPIMAT is NOT indicated for the relief of acute bronchospasm. 1.2 Maintenance Treatment of Asthma SPIRIVA RESPIMAT is a bronchodilator indicated for the long-term, once-daily, maintenance treatment of asthma in patients 6 years of age and older . Important Limitation of Use: SPIRIVA RESPIMAT is NOT indicated for the relief of acute bronchospasm.

2 DOSAGE AND ADMINISTRATION To receive the full dosage of medication, SPIRIVA RESPIMAT must be administered as two inhalations once-daily. Do not take more than one dose (2 inhalations) in 24 hours. Prior to first use, the SPIRIVA RESPIMAT cartridge is inserted into the SPIRIVA RESPIMAT inhaler and the unit is primed. When using the unit for the first time, patients are to actuate the inhaler toward the ground until an aerosol cloud is visible and then repeat the process three more times. The unit is then considered primed and ready for use. If not used for more than 3 days, patients are to actuate the inhaler once to prepare the inhaler for use. If not used for more than 21 days, patients are to actuate the inhaler until an aerosol cloud is visible and then repeat the process three more times to prepare the inhaler for use [see Patient Counseling Information (17) ]. For oral inhalation only. To receive the full dose of medication, SPIRIVA RESPIMAT must be administered as two inhalations once-daily. Treatment of COPD: 2 inhalations of SPIRIVA RESPIMAT 2.5 mcg once-daily. ( 2 ) Treatment of asthma patients 6 years and older: 2 inhalations of SPIRIVA RESPIMAT 1.25 mcg once-daily. ( 2 ) 2.1 Chronic Obstructive Pulmonary Disease The recommended dosage for patients with COPD is 2 inhalations of SPIRIVA RESPIMAT 2.5 mcg per actuation once-daily; total dose equals 5 mcg of SPIRIVA RESPIMAT. 2.2 Asthma The recommended dosage for patients with asthma is 2 inhalations of SPIRIVA RESPIMAT 1.25 mcg per actuation once-daily; total dose equals 2.5 mcg of SPIRIVA RESPIMAT. In the treatment of asthma, the maximum benefits in lung function may take up to 4 to 8 weeks of dosing [see Patient Counseling Information (17) ]. 2.3 Special Populations No dosage adjustment is required for geriatric, hepatically-impaired, or renally-impaired patients. However, patients with moderate to severe renal impairment given SPIRIVA RESPIMAT should be monitored closely for anticholinergic effects [see Warnings and Precautions (5.6) , Use in Specific Populations (8.5 , 8.6 , 8.7) , and Clinical Pharmacology (12.3) ] .

5 WARNINGS AND PRECAUTIONS Not for acute use, i.e., not a rescue medication. ( 5.1 ) Immediate hypersensitivity reactions: Discontinue SPIRIVA RESPIMAT at once and consider alternatives if immediate hypersensitivity reactions, including angioedema, urticaria, rash, bronchospasm, or anaphylaxis, occur. ( 5.2 ) Paradoxical bronchospasm: Discontinue SPIRIVA RESPIMAT and consider other treatments if paradoxical bronchospasm occurs. ( 5.3 ) Worsening of narrow-angle glaucoma may occur. Use with caution in patients with narrow-angle glaucoma and instruct patients to consult a physician immediately if this occurs. ( 5.4 ) Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patient to consult a physician immediately if this occurs. ( 5.5 ) 5.1 Not for Acute Use SPIRIVA RESPIMAT is intended as a once-daily maintenance treatment for COPD and asthma and should not be used for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. In the event of an acute attack, a rapid-acting beta 2 -agonist should be used. 5.2 Immediate Hypersensitivity Reactions Immediate hypersensitivity reactions, including urticaria, angioedema (including swelling of the lips, tongue or throat), rash, bronchospasm, anaphylaxis, or itching may occur after administration of SPIRIVA RESPIMAT. If such a reaction occurs, therapy with SPIRIVA RESPIMAT should be stopped at once and alternative treatments should be considered. Given the similar structural formula of atropine to tiotropium, patients with a history of hypersensitivity reactions to atropine or its derivatives should be closely monitored for similar hypersensitivity reactions to SPIRIVA RESPIMAT. 5.3 Paradoxical Bronchospasm Inhaled medicines, including SPIRIVA RESPIMAT, may cause paradoxical bronchospasm. If this occurs, it should be treated immediately with an inhaled short-acting beta 2 -agonist such as albuterol. Treatment with SPIRIVA RESPIMAT should be stopped and other treatments considered. 5.4 Worsening of Narrow-Angle Glaucoma SPIRIVA RESPIMAT should be used with caution in patients with narrow-angle glaucoma. Prescribers and patients should be alert for signs and symptoms of acute narrow-angle glaucoma (e.g., eye pain or discomfort, blurred vision, visual halos or colored images in association with red eyes from conjunctival congestion and corneal edema). Instruct patients to consult a physician immediately should any of these signs or symptoms develop. 5.5 Worsening of Urinary Retention SPIRIVA RESPIMAT should be used with caution in patients with urinary retention. Prescribers and patients should be alert for signs and symptoms of urinary retention (e.g., difficulty passing urine, painful urination), especially in patients with prostatic hyperplasia or bladder-neck obstruction. Instruct patients to consult a physician immediately should any of these signs or symptoms develop. 5.6 Renal Impairment As a predominantly renally excreted drug, patients with moderate to severe renal impairment (creatinine clearance of <60 mL/min) treated with SPIRIVA RESPIMAT should be monitored closely for anticholinergic side effects [see Clinical Pharmacology (12.3) ] .

4 CONTRAINDICATIONS SPIRIVA RESPIMAT is contraindicated in patients with a hypersensitivity to tiotropium, ipratropium, or any component of this product [see Warnings and Precautions (5.2) ] . In clinical trials with SPIRIVA RESPIMAT, immediate hypersensitivity reactions, including angioedema (including swelling of the lips, tongue, or throat), itching, or rash have been reported [see Warnings and Precautions (5.2) ] . Hypersensitivity to tiotropium, ipratropium, or any component of this product. ( 4 )

7 DRUG INTERACTIONS Anticholinergics: May interact additively with concomitantly used anticholinergic medications. Avoid administration of SPIRIVA RESPIMAT with other anticholinergic-containing drugs. ( 7.2 ) 7.1 Concomitant Respiratory Medications SPIRIVA RESPIMAT has been used concomitantly with short-acting and long-acting sympathomimetic (beta-agonists) bronchodilators, methylxanthines, oral and inhaled steroids, antihistamines, mucolytics, leukotriene modifiers, cromones, and anti-IgE treatment without increases in adverse reactions. 7.2 Anticholinergics There is potential for an additive interaction with concomitantly used anticholinergic medications. Therefore, avoid coadministration of SPIRIVA RESPIMAT with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects [see Warnings and Precautions (5.4 , 5.5) and Adverse Reactions (6) ].

8.1 Pregnancy Risk Summary The limited human data with SPIRIVA RESPIMAT use during pregnancy are insufficient to inform a drug-associated risk of adverse pregnancy-related outcomes. There are risks to the mother and the fetus associated with poorly controlled asthma in pregnancy (see Clinical Considerations ) . Based on animal reproduction studies, no structural abnormalities were observed when tiotropium was administered by inhalation to pregnant rats and rabbits during the period of organogenesis at doses 790 and 8 times, respectively, the maximum recommended human daily inhalation dose (MRHDID). Increased post-implantation loss was observed in rats and rabbits administered tiotropium at maternally toxic doses 430 times and 40 times the MRHDID, respectively (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Poorly or moderately controlled asthma in pregnancy increases the maternal risk of preeclampsia and infant prematurity, low birth weight, and small for gestational age. The level of asthma control should be closely monitored in pregnant women and treatment adjusted as necessary to maintain optimal control. Data Animal Data In 2 separate embryo-fetal development studies, pregnant rats and rabbits received tiotropium during the period of organogenesis at doses up to approximately 790 and 8 times the maximum recommended human daily inhalation dose (MRHDID), respectively (on a mcg/m 2 basis at inhalation doses of 1,471 and 7 mcg/kg/day in rats and rabbits, respectively). No evidence of structural abnormalities was observed in rats or rabbits. However, in rats, tiotropium caused fetal resorption, litter loss, decreases in the number of live pups at birth and the mean pup weights, and a delay in pup sexual maturation at tiotropium doses of approximately 40 times the MRHDID (on a mcg/m 2 basis at a maternal inhalation dose of 78 mcg/kg/day). In rabbits, tiotropium caused an increase in post-implantation loss at a tiotropium dose of approximately 430 times the MRHDID (on a mcg/m 2 basis at a maternal inhalation dose of 400 mcg/kg/day). Such effects were not observed at approximately 5 and 95 times the MRHDID, respectively (on a mcg/m 2 basis at inhalation doses of 9 and 88 mcg/kg/day in rats and rabbits, respectively).

6 ADVERSE REACTIONS The following adverse reactions are described, or described in greater detail, in other sections: Immediate hypersensitivity reactions [see Warnings and Precautions (5.2) ] Paradoxical bronchospasm [see Warnings and Precautions (5.3) ] Worsening of narrow-angle glaucoma [see Warnings and Precautions (5.4) ] Worsening of urinary retention [see Warnings and Precautions (5.5) ] Because clinical trials are conducted under widely varying conditions, the incidence of adverse reactions observed in the clinical trials of a drug cannot be directly compared to the incidences in the clinical trials of another drug and may not reflect the incidences observed in practice. Since the same active ingredient (tiotropium bromide) is administered to COPD and asthma patients, prescribers and patients should take into account that the observed adverse reactions could be relevant for both patient populations independent of dosage strength. The most common adverse reactions in: COPD: (>3% incidence in the placebo-controlled trials with treatment durations of between 4 and 48 weeks) were pharyngitis, cough, dry mouth, and sinusitis. ( 6.1 ). Asthma: (>2% incidence in the placebo-controlled trials with treatment durations of between 12 and 52 weeks) were pharyngitis, headache, bronchitis, and sinusitis in adults. ( 6.2 ).

Two trials were four-week cross-over trials and eight were parallel group trials. The parallel group trials included a three-week dose-ranging trial, two 12-week trials, three 48-week trials, and two trials of 4-week and 24-week duration conducted for a different program that contained tiotropium bromide 5 mcg treatment arms. The primary safety database consists of pooled data from the 7 randomized, parallel-group, double-blind, placebo-controlled studies of 4-48 weeks in treatment duration. These trials included 6,565 adult COPD patients (75% males and 25% females) 40 years of age and older. Of these patients, 3,282 patients were treated with SPIRIVA RESPIMAT 5 mcg and 3,283 received placebo. The SPIRIVA RESPIMAT 5 mcg group was composed mostly of Caucasians (78%) with a mean age of 65 years and a mean baseline percent predicted post-bronchodilator FEV 1 of 46%. In these 7 clinical trials, 68.3% of patients exposed to SPIRIVA RESPIMAT 5 mcg reported an adverse event compared to 68.7% of patients in the placebo group. There were 68 deaths in the SPIRIVA RESPIMAT 5 mcg treatment group (2.1%) and 52 deaths (1.6%) in patients who received placebo [see Clinical Studies (14) Long-term Active-Controlled Mortality Trial: Survival ] . The percentage of SPIRIVA RESPIMAT patients who discontinued due to an adverse event were 7.3% compared to 10% with placebo patients. The percentage of SPIRIVA RESPIMAT 5 mcg patients who experienced a serious adverse event were 15.0% compared to 15.1% with placebo patients. In both groups, the adverse event most commonly leading to discontinuation was COPD exacerbation (SPIRIVA RESPIMAT 2.0%, placebo 4.0%) which was also the most frequent serious adverse event. The most commonly reported adverse reactions were pharyngitis, cough, dry mouth, and sinusitis (Table 1). Other adverse reactions reported in individual patients and consistent with possible anticholinergic effects included constipation, dysuria, and urinary retention. Table 1 shows all adverse reactions that occurred with an incidence of >3% in the SPIRIVA RESPIMAT 5 mcg treatment group, and a higher incidence rate on SPIRIVA RESPIMAT 5 mcg than on placebo.
