Indications & Uses

Daiza is indicated for:

Pharmacology

Diazepam binds to a specific site on the GABA receptor and boosts the effect of GABA, which works by opening chloride ion channels into cells. Taken by mouth, diazepam is absorbed rapidly and completely, with plasma levels peaking within 15-90 minutes. Its average plasma half-life is 30 hours, and it is 98-99% bound to plasma proteins. The liver metabolizes diazepam, and only traces of the unchanged drug appear in urine; a very small portion of its metabolites passes through the bile into the intestine and leaves the body in the feces. Given rectally as a suppository, diazepam is also well absorbed, with plasma levels peaking within 1.5-2 hours.
