Olanzapinum est substantia antipsychotica et propterea medicamentum ad therapiam schizophreniarum.
Historia
[recensere | fontem recensere]Ab anno 1970 fabricantur diversae substantiae antipsychoticae, atypica quoque vocatae. Inter ea primo Clozapinum fuit, denique ab anno 1971 Olanzapinum, quod usus medicorum ab anno 1996 ad emporium delatum est. Olanzapinum, ut Clozapinum, et receptoria D2 et receptoria serotonini 5-HT1A obsidet, at praeterea minius effectus adversaria observari possunt. Anno 1985 dibenzothiazepino derivata Quetiapinum, simul Clozapino Olanzapinoque simile sed cum grege adiecto, divulgatum est.[1]
