Polypharmacy, using multiple medications, poses risks for people with HIV (PLWH) due to increased medication interactions, adverse events, and frailty. This study proposes a framework to manage polypharmacy in lifelong combination antiretroviral therapy (ART).
Area of Science:
- Geriatrics
- Infectious Diseases
- Pharmacology
Background:
- Combination antiretroviral therapy (ART) is standard for HIV, often leading to polypharmacy (≥5 medications).
- Polypharmacy increases risks of nonadherence, adverse drug events, organ injury, hospitalization, geriatric syndromes, and mortality in people with HIV (PLWH).
- Existing polypharmacy literature needs adaptation for PLWH due to lifelong ART, higher comorbidity risk, and enhanced susceptibility to harm.
Purpose of the Study:
- To review the literature on polypharmacy in PLWH on chronic ART.
- To propose an adapted framework for managing polypharmacy in this population.
- To identify future research directions for addressing polypharmacy in PLWH.
Main Methods:
- Literature review of polypharmacy in HIV and non-HIV populations.
- Adaptation of existing polypharmacy frameworks for the unique context of lifelong ART.
- Identification of specific challenges and considerations for PLWH.
Main Results:
- Polypharmacy is a significant concern for PLWH, with risks amplified by age, frailty, and HIV-specific factors.
- Lifelong ART necessitates tailored approaches to polypharmacy management.
- PLWH may have increased vulnerability to polypharmacy harms due to chronic inflammation and immune dysfunction.
Conclusions:
- An adapted framework is proposed to address polypharmacy challenges in individuals on lifelong ART.
- Further research is needed to optimize polypharmacy management strategies for PLWH.
- Addressing polypharmacy is crucial for improving health outcomes and quality of life for aging PLWH.
