How it works

From the US prescribing label for the same active substance (VERSACLOZ). It describes the substance, not this exact product.

The mechanism of action of clozapine is unknown.

However, it has been proposed that the therapeutic efficacy of clozapine in schizophrenia is mediated through antagonism of the dopamine type 2 (D 2 ) and the serotonin type 2A (5-HT 2A ) receptors.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Metabolism and Excretion VERSACLOZ is almost completely metabolized prior to excretion, and only trace amounts of unchanged drug are detected in the urine and feces.

How it leaves the body

Approximately 50% of the administered dose is excreted in the urine and 30% in the feces.

With food

When VERSACLOZ was administered after a high fat meal there was no effect on the AUC ss or C min, ss, however C max was reduced about 20%, and there was a slight delay in T max of 0.5 hour from a median T max of 2.0 hours under fasted conditions to 2.5 hours under fed conditions.
