There was no substantial difference in anti-depressive effectiveness among olanzapine, quetiapine, risperidone or ziprasidone in this clinically
One day after Eli Lilly and Company researchers reported finding olanzapine (Zyprexa) superior to risperidone (Risperdal) on some measures in
Because olanzapine is closely related in chemical structure to clozapine and shares many common receptor binding characteristics (binding affinities for D2, HT2a, HT2c, alpha2, M1 receptors) (Bymaster et al
Long-acting risperidone and paliperidone are well tolerated and half of the conventional dose may be effective in the case of paliperidone
30 A higher propensity to gain weight is also seen in patients with People allocated to risperidone were less likely to gain weight compared with those given olanzapine and the weight gain was often considerable and of quick onset (n=984, 2 RCTs, RR gain more than 7% of their baseline weight in short term 0
Olanzapine 80mg better than risperidone 15mg
Risperidone versus olanzapine
39% of reviewers reported a positive effect, while 38% reported a negative Olanzapine showed efficacy at lower mean chlorpromazine equivalents vs
For the outcome of relapse/rehospitalisation, people allocated olanzapine fared a little better than risperidone (NNT 13 CI 6 to 421)
To protect the blinding of treatment with the newer atypical antipsychotics, half of the patients randomly assigned to olanzapine and risperidone were assigned to twice a day and half to once a day dosing
Risperidone is an antipsychotic that relieves psychotic symptoms in people with schizophrenia or mania and is also used in the treatment of autistic disorder

No other atypical studied (risperidone, quetiapine, and ziprasidone) did better than the typical perphenazine on the measures used, During the 1990s, olanzapine, risperidone, and quetiapine were introduced, with ziprasidone and aripiprazole following in the early 2000s
