Loxapine (Adasuve) vs Ziprasidone
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.

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).
Ziprasidone
Marketed by Pfizer and partners
NCT00159770 · Phase 3 · completed
The study used randomization and active comparators but was open-label, with 290 participants, and its primary clinical endpoint was PANSS symptom change. No results are posted, so the primary endpoint cannot be classified as met or missed.
Next expected readout: February 2027 · NCT03781115 (registry estimate)
