Olanzapine
Aliases: Lanzac, Zyprexa, Olansek, Symbyax, Olanzapin
Summary
Community reports describe near-complete termination of LSD or psilocybin effects within ~30 min after a 5-10 mg orally-disintegrating dose, usually followed by deep sleep. Controlled studies show a single 10 mg IM injection quells acute agitation as effectively as haloperidol but with fewer extrapyramidal reactions. Orally-disintegrating formulations dissolve in under one minute and reach measurable plasma levels faster than standard tablets.
