Drug interactions associated with methadone, buprenorphine, cocaine, and HIV medications: Implications for pregnant women.
Summary of "Drug interactions associated with methadone, buprenorphine, cocaine, and HIV medications: Implications for pregnant women."
Pregnancy in substance-abusing women with HIV/AIDS presents a complex clinical challenge. Opioid-dependent women need treatment with opioid therapy during pregnancy to protect the health of mother and developing fetus. However, opioid therapies, methadone and buprenorphine, may have drug interactions with some HIV medications that can have adverse effects leading to suboptimal clinical outcomes. Further, many opioid-dependent individuals have problems with other forms of substance abuse, for example, cocaine abuse, that could also contribute to poor clinical outcomes in a pregnant woman. Physiological changes, including increased plasma volume and increased hepatic and renal blood flow, occur in the pregnant woman as the pregnancy progresses and may alter medication needs with the potential to exacerbate drug interactions, although there is sparse literature on this issue. Knowledge of possible drug interactions between opioids, other abused substances such as cocaine, HIV therapeutics, and other frequently required medications such as antibiotics and anticonvulsants is important to assuring the best possible outcomes in the pregnant woman with opioid dependence and HIV/AIDS.

Among agents for treatment of opioid addiction, methadone is a full mu-opioid receptor agonist, whereas buprenorphine is a partial agonist. Both are long-acting. Buprenorphine has a superior safety pr...
Methadone maintenance treatment and buprenorphine maintenance treatment are the two main therapeutic options considered for opioid replacement therapy. This study was conducted to examine the effectiv...
Background: Methadone is widely accepted as the most effective treatment of opioid dependence. However, clinical observations indicate that the medication is less effective in individuals abusing coca...
Cocaine pharmacotherapy trials are often confounded by considerable variability in baseline cocaine-use levels, obscuring possible medication efficacy. Testing the feasibility of using a prerandomizat...
Buprenorphine maintenance treatment has been evaluated in randomised controlled trials against placebo medication, and separately as an alternative to methadone for management of opioid dependence.
The purpose of this study is to compare the effects of buprenorphine or methadone maintenance on cocaine taking and on the physiological and subjective effects of cocaine, including cocain...
We hypothesize that integrating Hepatitis C into methadone and buprenorphine treatment will improve Hepatitis C outcomes as well as drug treatment outcomes in patients who are addicted to...
The purpose of this study is to compare the clinical efficacy of maintenance on low and high doses of buprenorphine with methadone for cocaine abusing opiate addicts.
Buprenorphine is an important alternative to methadone in the maintenance treatment of heroin addiction. Transfer from methadone to buprenorphine requires a reduction of daily methadone do...
Concurrent dependence on cocaine occurs in up to 50% of the over one million opiate dependent patients in spite of methadone maintenance treatment being highly effective for opiate depende...
Medical and Biotech [MESH] Definitions
Medical treatment for opioid dependence using a substitute opiate such as METHADONE or BUPRENORPHINE.
An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Methadone is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)
The action of a drug that may affect the activity, metabolism, or toxicity of another drug.
The purified, alkaloidal, extra-potent form of cocaine. It is smoked (free-based), injected intravenously, and orally ingested. Use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. The slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.
