Patients with a major psychotic disorder should not be treated with INBRIJA ( 5.3 , 7.2 ) Impulse Control Disorders: consider dose reduction or stopping INBRIJA ( 5.4 ) May cause or exacerbate dyskinesia: adjustment of levodopa therapy may be considered, including stopping INBRIJA ( 5.5 ) Not recommended in patients with asthma, COPD, or other chronic underlying lung disease ( 5.6 )

5.1Falling Asleep During Activities of Daily Living and Somnolence

Patients treated with levodopa, the active ingredient in INBRIJA, have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes resulted in accidents. Although many of these patients reported somnolence, some reported no warning signs (sleep attack) and believed that they were alert immediately prior to the event. Some of these events have been reported more than 1 year after the initiation of treatment.

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Adverse Reactions in Study 1 Table 1 lists the adverse reactions that occurred in at least 2% of patients with Parkinson's disease who were treated with INBRIJA 84 mg and higher than placebo for OFF periods in Study 1 [see Clinical Studies (14) ].

Study 1 was a double-blind, placebo-controlled study, in which 114 patients received INBRIJA 84 mg (two 42 mg capsules) for an average of 2 doses per day, to a maximum of 5 times a day, and 112 patients received placebo. INBRIJA-treated patients were 45-82 years of age (mean 63.5 years of age) and were predominantly male (72%) and white (94%). All patients were also treated with oral carbidopa/levodopa. The most common adverse reactions (≥ 5% and higher than placebo) in Study 1 were cough, nausea, upper respiratory tract infection, and sputum discolored.

The most common of these adverse reactions was cough, which lead to discontinuation in 2% of patients in the INBRIJA 84 mg group and none in the placebo group.

6.2Postmarketing Experience

The following adverse reaction has been identified during post approval use of INBRIJA. Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: sensation of choking immediately following administration.
