Head-to-head evidence
Loxapine (Adasuve) vs Risperidone (Risperdal)
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Shared mechanism: Dopamine D2 and serotonin 5-HT2A receptors (antagonist) · full Schizophrenia pipeline
Loxapine (Adasuve)
Marketed by Lee's Pharmaceutical
NCT00628589 · Phase 3 · completed
The trial randomly assigned 344 participants to inhaled loxapine 5 mg, loxapine 10 mg, or placebo and used quadruple blinding of participants, care providers, investigators, and outcome assessors. Its primary clinical agitation measure was significantly improved with both loxapine doses compared with placebo (p=0.0004 and p<0.0001).
Risperidone (Risperdal)
Marketed by Johnson & Johnson
NCT00253136 · Phase 3 · completed
The study randomized 458 participants to double-blind risperidone or placebo, with change in the clinical PANSS score as the primary endpoint. Because the registry does not report whether this endpoint was met, the trial provides a well-controlled design but no assessable result.
Next expected readout: December 2026 · NCT06482554 (registry estimate)
