Atipamezole (brand name Antisedan, Pfizer) is a synthetic α₂ adrenergic receptor antagonist, indicated for the reversal of the sedative and analgesic effects of dexmedetomidine and medetomidine in dogs.^[1]

It has also been researched in humans as a potential anti-Parkinsonian drug.^[2]

Dosing[edit]

In a study using New Zealand white rabbits, the optimal dose for revival of sedation by a medetomidine-ketamine mixture was found to be equal to or double the dose of medetomidine.^[3]
