Description and Uses

Pentylenetetrazole (PTZ) is a central nervous system modulator that is used to experimentally induce seizures in animals. Subcutaneous PTZ has been used extensively to screen for compounds that block the production of nonconvulsive (absence or myoclonic) seizures. PTZ has diverse, site-specific effects in the brain. However, it is an antagonist of GABA_A receptors and some drugs that block PTZ-induced seizures, including benzodiazepines, act at the GABA_A receptor.

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