Viminol (marketed under the brandname Dividol) is a drug which is an opioid analgesic. It has an unusual chemical structure that is not similar to other opioids.[1][2]

Viminol has both antitussive (cough suppressing) and analgesic (pain reducing) effects. It has six different stereoisomers which have varying properties, with the 2-(R) isomer being a μ-opioid full agonist slightly more potent than morphine, while the 2-(S) isomer is an antagonist.[3] Since vimonol is supplied as a racemic mixture of isomers, the overall effect produces a mixed agonist-antagonist profile similar to that of opioids such as pentazocine, although with somewhat less side effects.[4]

Viminol has similar effects to other opioids, and produces analgesia, sedation and euphoria.

Side Effects

Side effects are similar to other opioids, and can include:

However, since viminol is supplied as a racemic mixture of agonist and antagonist isomers, the abuse potential and respiratory depression tends to be less than that of μ-opioid full agonist drugs.
