ADASUVE is available only through the ADASUVE Risk Evaluation and Mitigation Strategy (REMS) Program. The healthcare facility must be enrolled in the ADASUVE REMS Program before you can be given ADASUVE.
ADASUVE may cause serious side effects, including:
- Narrowing of the airways (bronchospasm) that can cause you to have problems breathing or to stop breathing.

Adasuve, a typical antipsychotic, is an inhalation powder of loxapine supplied in a single-use, disposable inhaler containing 10 mg of loxapine base. Adasuve is a drug-device combination product.
Active Ingredient: Loxapine (base). Loxapine, a dibenzoxazepine compound, represents a subclass of tricyclic antipsychotic agents, chemically distinct from the thioxanthenes, butyrophenones, and phenothiazines. Chemically, it is 2-Chloro-11-(4-methyl-1-piperazinyl) dibenz [b,f] [1,4] oxazepine.
Adasuve is a single-use, drug-device combination product that provides rapid systemic delivery by inhalation of a thermally-generated aerosol of loxapine. Oral inhalation through the product initiates the controlled rapid heating of a thin film of excipient-free loxapine to form a thermally-generated drug vapor. The vapor condenses into aerosol particles that are dispersed into the airstream created by the patient inhaling through the mouthpiece.
Each product is packaged inside a sealed foil pouch. The product is a white to off-white plastic unit, with a mouthpiece on one end and a pull-tab protruding from the other end.
Removal of a pull-tab from the product renders it ready for use, as indicated by illumination of a green light. After inhalation through the mouthpiece, successful dosing is signaled by the green light turning off.
Under standardized in vitro test conditions, Adasuve, 10 mg delivers 9.1 mg of loxapine out of the mouthpiece.
The efficacy of Adasuve 10 mg in the acute treatment of agitation associated with schizophrenia or bipolar I disorder was established in two short-term (24-hour), randomized, double-blind, placebo-controlled, fixed-dose trials. Study 1 included 344 patients who met DSM-IV criteria for schizophrenia. Study 2 included 314 patients who met DSM-IV criteria for bipolar I disorder, manic or mixed episodes with or without psychotic features.
Patients were judged by the clinical investigators to be clinically agitated, with a level of agitation that met or exceeded a specific severity threshold as measured by the Positive and Negative Syndrome Scale-Excited Component (PEC). The PEC is an investigator-rated instrument consisting of 5 items: poor impulse control, tension, hostility, uncooperativeness, and excitement. Each item is scored on a scale from 1 to 7 (1 = absent, 4 = moderate, 7 = extreme). Thus, the total PEC score can range from 5 to 35. For enrollment in the studies, patients had to have a PEC score of ≥ 14, with at least one individual item score > 4.
Patients whose agitation was related to acute alcohol or drug intoxication were excluded. Patients with clinically significant acute or chronic pulmonary disease (e.g., asthma, COPD, chronic bronchitis, and emphysema) were excluded from the trials [See Contraindications (4)].
The primary efficacy endpoint in both trials was the mean change from baseline in the PEC score, assessed 2 hours following dosing. The key secondary endpoint was the mean Clinical Global Impression Improvement (CGI-I) Scale score at two hours. The CGI-I is an investigator-rated global assessment of symptom improvement, scored on a scale of 1 to 7: 1 = very much improved; 4 = no change from baseline; 7 = very much worse.
In both studies, mean baseline PEC scores were similar in all treatment groups, averaging 17.3 to 17.7 (Table 4), with individual patient scores ranging from 14 to 31, indicating predominantly moderate levels of agitation. The mean baseline Clinical Global Impression Severity Scale (CGI-S) score in both studies was 4 (moderately ill). In Study 2, 69% of patients had a current manic episode, and 31% had a mixed/manic episode.
In Studies 1 and 2, treatment with Adasuve was statistically significantly superior to placebo on the mean change in PEC score at 2 hours (Table 4). In both studies, the effect of Adasuve was apparent at 10 minutes following dosing (Figures 9 and 10).

b Least squares mean for the difference defined as the change from baseline at hour 2 in the drug group minus that in the placebo group.
Examination of population subsets (age, race, and gender) on the primary endpoint did not reveal any differential responsiveness on the basis of these subgroupings.
Figures 9 and 10 show the decreases in PEC score at each time point assessed in the trials. In both trials, the decrease in agitation with Adasuve was apparent at each time point tested (10, 20, 30, 45, 60, 90, and 120 minutes post-dose).
