Weight-loss pharmacotherapies could also be used to handle weight problems in HIV sufferers, nevertheless, healthcare suppliers ought to concentrate on the potential of lack of HIV viremia management when combining these medicines with antiretrovirals agents, in keeping with the findings of a current evaluate.
To analyze potential drug-drug interactions between anti-obesity medication and antiretroviral remedy (ART), research authors performed a search utilizing PubMed, MEDLINE, Google Scholar, and EMBASE to acquire literature revealed between October 2018 and September 2019 that analyzed the protection and efficacy of Meals & Drug Administration (FDA)-approved weight reduction medicines in individuals dwelling with HIV. They recognized and included a complete of two case studies, 2 case collection, 6 ART-specific pharmacokinetic research, 36 medical trials, and 13 package deal inserts of their evaluate.
“Individuals dwelling with HIV are incessantly not reported or included in medical trials for weight-loss medicines, nevertheless, remedy efficacy is probably going much like the final inhabitants,” the research authors reported. A number of case studies obtained throughout their search, nevertheless, did focus on the potential of HIV viral rebound in sufferers taking orlistat.
“A number of essential reported or theoretical drug-drug interactions exist between anti-obesity pharmacotherapy and antiretroviral remedy,” the authors said. The report highlighted a number of mechanisms by which anti-obesity medicines might work together with antiretroviral brokers, such because the change in absorption of a drugs (ie, concomitant use of orlistat and non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase inhibitors) and inhibition or induction of cytochrome P450 (CYP) enzymes (ie, inhibition of CYP2D6 by lorcaserin); normally, the authors really useful avoiding using orlistat in sufferers on ART. Liraglutide was famous to be one of many weight-loss medicines that had minimal drug interactions.
As for naltrexone-bupropion, elevated monitoring is really useful when the drug is co-administered with ritonavir-boosted protease inhibitors, efavirenz, nevirapine, or cobicistat-containing regimens. Whereas there seems to be a low danger of interplay between phentermine-topiramate and ART, elements comparable to prescription abuse and heart problems must be thought-about earlier than beginning remedy with this agent.
Based mostly on their findings, the authors concluded that along with life-style modifications, clinicians ought to take into account FDA-approved weight reduction medicines to handle and deal with weight problems in sufferers with HIV. “Every agent has its personal particular caveats, counseling factors, and monitoring parameters, which must be thought-about when mixed with ART,” they famous.
