Pool-data of clinical cases of inhaled loxapine (Adasuve)

Abstract

Introduction

Agitation is a psychiatric emergency that requires immediate assistance. Inhaled loxapine is a new option for achieving rapid tranquillisation avoiding coercive measures and over-sedation, which fits with patient's preferences and increases their satisfaction with treatment.

Objective

Review the experience of use of inhaled loxapine in clinical practice.

Methods

We included data from all reports of case series with 10 or more patients published by European prescribers.

Results

Ten posters were included that reported data on 116 patients, mostly diagnosed with psychotic or bipolar diseases. Among the 60 patients that were evaluated using PANSS-EC, baseline agitation intensity was above 20 in 45 of them (75%) and between 15 and 32 in 15 (25%). Regarding patients evaluated with the CGI-S scale, 17 patients had a score between 6 and 7 points and 4 had scores between 4 and 5. All patients were able to properly inhalate the drug. In some patients agitation receded as early as 2 minutes, and almost all of them were controlled within 10 minutes. Only 6 patients required the 2nd dose of loxapine within 24 hours. When patients were asked for, they showed a preference for inhaled administration instead of intramuscular one, manifested high levels of satisfaction with inhaled treatment, and in one report inhaled loxapine was stated to contribute to avoid mechanical restraint. Inhaled loxapine was well tolerated and no over-sedation was reported or any EPS, just a case of mild orthostatic hypotension.

Conclusion

This pool-data review of inhaled loxapine in real world clinical practice shows that it is an effective treatment, with a very rapid response, easy to administer and well tolerated, with a good acceptance from patients.
