Individuals with a substance use disorder who are infected with human immunodeficiency virus (HIV) provide physicians with challenging issues for both medical management and drug treatment. Using a case presentation format, we present an overview of some of the major issues involved in delivering effective primary care for these individuals. A detailed medical and substance use history is critical to sort common complaints that can be seen both in HIV infection and with drug use. Physicians must be able to recognize withdrawal syndromes and differentiate those signs and symptoms that may be attributed to specific drugs. A two-phase model of drug abuse treatment takes into account both detoxification and maintenance of abstinence. Primary care physicians should be able to initiate the process of substance abuse treatment and refer the patient to appropriate substance abuse programs when necessary. Pharmacological approaches to long-term abstinence with heroin addiction include methadone, LAAM, and naltrexone. While clinically challenging, HIV-infected substance users can be successfully managed using the general principles of primary care.

Injection drug users are frequently infected with human immunodeficiency virus (HIV) and receive opioid dependence pharmacotherapies and zidovudine (ZDV), the latter as a component of highly active antiretroviral therapy. We previously reported that methadone substantially increases ZDV concentrations. We now report on oral ZDV pharmacokinetics in 52 subjects receiving the opioid dependence pharmacotherapies l-alpha-acetylmethadol LAAM, buprenorphine, or naltrexone, and 17 non-opioid-treated controls. Relative to the area under the time-concentration curve (AUC) of ZDV in control subjects, no statistically significant differences in ZDV AUC were observed in participants treated with LAAM (p = .75), buprenorphine (p = .37), or naltrexone (p = .34). While methadone maintenance may result in ZDV toxicity and possibly require dose adjustments, other opioid pharmacotherapies should not produce ZDV toxicity.
