Atypical neuroleptic drugs
Pharmacology
Oleanz 10 mg is an antipsychotic agent and has affinities for serotonin 5HT2A/2C, 5HT3, 5HT6; dopamine D1, D2, D3, D4, D5; cholinergic muscarinic receptors M1-M5; α1 adrenergic; and histamine H1 receptors. The mechanism of action of Oleanz 10 mg, as with other drugs having efficacy in schizophrenia, is unknown. However, it has been proposed that this drug’s efficacy in schizophrenia is mediated through a combination of dopamine and serotonin type 2 (5HT2) antagonism. Oleanz 10 mg is well absorbed after oral administration, reaching peak plasma concentrations within 5 to 8 hours. The absorption is not affected by food. Oleanz 10 mg is not mutagenic or clastogenic as well as not carcinogenic.
Dosage & Administration of Oleanz 10 mg
The recommended starting dose for Oleanz 10 mg is 10 mg/day, administered as a single daily dose without regard to meals. Daily dosage may subsequently be adjusted on the basis of individual clinical status within the range of 5-20 mg daily. An increase to a dose greater than the routine therapeutic dose of 10 mg/day i.e. to a dose of 15 mg/day or greater, is recommended only after appropriate clinical reassessment.When more than one factor is present which might result in slower metabolism (female gender, geriatric age, non-smoking status), consideration should be given to decreasing the starting dose. Dose escalation, when indicated, should be conservative in such patients.

Interaction of Oleanz 10 mg
Oleanz 10 mg may antagonize the effects of levodopa and dopamine agonists. Drugs that induce CYP1A2 or glucoronyl transferase enzymes e.g, Omeprazole and Rifampicin, may increase Oleanz 10 mg clearance. Inhibitors of CYP1A2 may potentially inhibit Oleanz 10 mg elimination. Carbamazepine may increase the clearance of Oleanz 10 mg. Concomitant administration of activated charcoal reduces the oral bioavailability of Oleanz 10 mg by 50-60%. Caution should be taken when Oleanz 10 mg is administered with centrally acting drugs and alcohol.
