Substitute drugs for other forms of drug dependence have historically been less successful than opioid substitute treatment, but some limited success has been seen with drugs such as dexamphetamine to treat stimulant addiction, and clomethiazole to treat alcohol addiction. Bromocriptine and desipramine have been reported to be effective for treatment of cocaine but not amphetamine addiction.
Other pharmacological treatments for alcohol addiction include drugs like naltrexone, disulfiram, acamprosate and topiramate, but rather than substituting for alcohol, these drugs are intended to reduce the desire to drink, either by directly reducing cravings as with acamprosate and topiramate, or by producing unpleasant effects when alcohol is consumed, as with disulfiram. These drugs can be effective if treatment is maintained, but compliance can be an issue as alcoholic patients often forget to take their medication, or discontinue use because of excessive side effects. Additional drugs acting on glutamate neurotransmission such as modafinil, lamotrigine, gabapentin and memantine have also been proposed for use in treating addiction to alcohol and other drugs.
Opioid antagonists such as naltrexone and nalmefene have also been used successfully in the treatment of alcohol addiction, which is often particularly challenging to treat. These drugs have also been used to a lesser extent for long-term maintenance treatment of former opiate addicts, but cannot be started until the patient has been abstinent for an extended period, otherwise they can trigger acute opioid withdrawal symptoms.
