General description

Pentylenetetrazole (PTZ) is a tetrazole derivative and inhibitor of the γ aminobutyric acid (GABAA) and its receptor complex. PTZ is a convulsing agent used for inducing seizures. It can traverse the blood-brain barrier.

Application

Pentylenetetrazole has been used to induce seizures in zebra fish larvae, mice, and male wistar rats.

Packaging

25, 50, 100 g in poly bottle

Biochem/physiol Actions

Pentylenetetrazole is a non-specific central nervous system (CNS) stimulant and convulsant. PTZ induces oxidative stress and increases cortical malondialdehyde content and affects hippocampus, resulting in seizures.
