Viminol

Overview
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.

Viminol has both antitussive (cough suppressing) and analgesic (pain reducing) effects. It has six different stereoisomers which have varying properties, with the R2 isomer being a μ-opioid full agonist slightly more potent than morphine, while the S2 isomer is an antagonist. 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.

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

Side Effects
Side effects are similar to other opiods, and can include:
 * Itching
 * Nausea
 * Sedation
 * Respiratory depression - can be potentially life-threatening

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.
