Pharmacotherapy in addiction management utilizes medications to treat addiction's physiological and psychological aspects. Aversive agents like Disulfiram, agonists such as Methadone and Buprenorphine, and antagonists including Naltrexone, play distinct roles in recovery. These treatments, alongside psychosocial support, aim to reduce withdrawal symptoms, cravings, and the reinforcing effects of addictive substances, contributing to improved treatment outcomes.

Pharmacotherapy involves the use of medication to treat addiction, with three main types: aversive agents, agonists, and antagonists
Clinical evidence for aversive agents
Aversive agents have been shown to be effective in promoting abstinence when combined with behavioral therapies
Studies on agonist medications
Methadone and buprenorphine have been found to improve treatment retention and reduce illicit opioid use
Effectiveness of antagonist medications
Antagonists are most effective when used as part of a broader treatment strategy that includes behavioral interventions
Challenges such as side effects and ethical considerations must be addressed when using pharmacotherapy in addiction treatment
Aversive agents induce unpleasant effects to deter further use of addictive substances
Agonist medications alleviate withdrawal symptoms and reduce cravings by activating the same receptors as the abused substance
