Sample Use Guides

In Vivo Use Guide

In a clinical trial, glemanserin was given at a dose of 32 mg thrice daily.

Route of Administration: Oral

In Vitro Use Guide

Glemanserin (10(-7)-10(-6) M was incubated with guinea pig papillary muscle and dog Purkinje fiber. At that concentrations, the drug increased the action potential duration in both tissues with a maximum effective concentration of 10(-6) to 3 x 10(-6) M.
