In examination papers expelled late on Wednesday, FDA staff pronounced they were uncertain either Adasuve was protected for patients, nonetheless it successfully treated their agitation.
"The multiplication stays endangered that a loyal astringency and border of pulmonary toxicity in a dictated diagnosis race is unknown," one FDA reviewer wrote.
The FDA deserted a drug in Oct 2010 since of breathing-related side effects.
The lecture papers suggested group staff were doubtful a reserve problems had been addressed after a company's resubmission in August.
Three injectable drugs -- Bristol-Myers Squibb's Abilify, Eli Lilly's Zyprexa and Pfizer's Geodon -- are already authorized to ease down patients with a mental illnesses, though Alexza's drug would be a initial that is inhaled.
Adasuve is vaporized and delivered by a company's Staccato inhaler, so flitting by a lungs and into a blood tide faster than a standard pill. Patients were noticeably calmer within 15 minutes, a FDA said.
But in clinical trials, Adasuve was associated to lung problems including serious obstruction of a airway muscles, or bronchospasm, generally for people who had a story of asthma or lung disease.
To residence a reserve concerns, Alexza due screening patients for risks before treatment, and monitoring them in a sanatorium after they get a drug to make certain they do not have respirating problems.
But a FDA pronounced many patients with schizophrenia or bipolar commotion are smokers, and it might be formidable to observe respirating problems in people who are agitated.
"Acutely vibrated schizophrenic or bipolar patients presenting to an puncture room or other trickery might be uncooperative, psychotic, and exceedingly disorganized," wrote an FDA reviewer.
A row of outward experts that will accommodate on Monday was asked to cruise either a company's plan will residence a reserve issues, and will opinion on either to suggest capitulation of a drug.

Acute restlessness can means patients to turn uncomfortable, moving and nervous and if untreated, patients can turn melancholy and aroused as a restlessness intensifies, Alexza has said.
The FDA declined to approve Adasuve in Oct 2010 since of serious side effects associated to respirating seen in 3 early-stage reserve studies. The group also highlighted some production and engineering problems, that it pronounced on Wednesday a association had resolved with a resubmission.
Adasuve would be a company's initial FDA-approved product. Alexza pronounced it expects a FDA to make a final preference about a drug in early 2012.
