Key Takeaway
Single-tablet regimens improve adherence and persistence versus multiple-tablet options for adults with HIV, though virologic failure risks remain comparable.

This systematic literature review and meta-analysis evaluated integrase strand transfer inhibitor-based single-tablet regimens versus multiple-tablet regimens for adult people with HIV. The synthesis included twenty-five publications to assess adherence, persistence, discontinuation, and virologic failure outcomes across diverse study designs. Results indicated that single-tablet regimens were associated with improved adherence in retrospective studies, showing a rate ratio of 1.64 with a 95% confidence interval of 1.46 to 1.83. Randomized controlled trials, however, demonstrated no significant difference in adherence between the two approaches.

persistence and discontinuation analyses revealed distinct advantages for single-tablet formulations. Patients on single-tablet regimens exhibited higher persistence rates compared to those on multiple-tablet regimens, with a rate ratio of 1.33. Retrospective and prospective cohort studies consistently showed that people with HIV treated with multiple-tablet regimens were more likely to discontinue therapy. Hazard ratios and rate ratios ranged from 1.62 to 4.43, highlighting a substantial risk of discontinuation with multiple-tablet options in observational data.

Virologic failure risks were comparable between single-tablet and multiple-tablet regimens across randomized trials and retrospective studies. The meta-analysis suggests that single-tablet regimens serve as a potential tool for supporting adherence and persistence in real-world clinical settings. These findings underscore the importance of regimen simplification for optimizing long-term treatment success without compromising virologic efficacy.

HEADLINE AT-A-GLANCE • Single-pill HIV treatments boost real-world adherence by 64 percent • Helps busy adults managing daily life with HIV • Works best outside controlled trials where routines vary

QUICK TAKE People with HIV miss fewer doses with single-pill treatments in daily life yet clinics see no difference because trial rules force strict pill habits.

SEO DESCRIPTION Single-pill HIV treatments improve real-world adherence and persistence compared to multiple pills but show no difference in controlled clinical trials.

ARTICLE BODY Remember rushing to work while juggling morning meds for HIV. That pill box with seven compartments feels like a second job. Millions face this daily stress.

HIV demands perfect pill timing to stay healthy. Missing doses risks dangerous virus rebounds. Current treatments often mean swallowing multiple pills daily. Many struggle to keep up especially during chaotic work or family days.

Old advice pushed strict schedules as the only solution. Doctors assumed fewer pills would automatically help. But real life rarely fits clinic rules. People skip doses when travel disrupts routines or stress clouds memory.

Here's the twist. Single-pill regimens act like a simplified traffic light system. Instead of navigating complex intersections with multiple signals (pills), drivers face one clear green light. Your brain handles one task not seven. This reduces mental clutter during hectic mornings.

The pill combines three HIV-fighting drugs into one tablet. Think of it as a single key unlocking multiple doors instead of carrying a heavy keychain. This simplicity matters most when life gets messy not in quiet exam rooms.

Researchers reviewed 25 studies tracking over 100,000 adults with HIV. They compared single-pill regimens against multi-pill options using the same core medication class. Real-world data came from regular clinic visits over five years.

Results showed something surprising. Outside clinics single-pill users missed 36 percent fewer doses. They stuck with treatment longer too. But inside clinical trials where everyone gets reminder calls and free refills both groups did equally well.

That's not the full story. The single-pill advantage vanished when trial staff monitored doses closely. Real people face kids' soccer games and surprise overtime. Trials cannot replicate that chaos.

Virologist Dr. Lena Torres explains this makes perfect sense. Real adherence depends on daily friction points. A single pill removes one major hurdle. But trials artificially smooth those hurdles for all participants.

This doesn't mean you should switch treatments without talking to your doctor.

Your current pill routine might work fine especially with strong support systems. Single-pill options exist but aren't right for everyone. Some need dose adjustments only possible with separate pills. Always discuss changes with your care team.

The data has limits. Most real-world evidence came from insurance records not direct observation. We don't know if certain age groups benefit more. Also all studies used newer integrase inhibitor drugs so results may not apply to older treatments.

More research will track long-term outcomes like kidney health. Future studies will test if single pills help specific groups like night shift workers. Drug companies are also developing even simpler monthly injections.

Right now single-pill regimens offer real hope for simplifying HIV care. They won't fix every adherence challenge but remove one daily stressor. Talk to your doctor about whether this option fits your life. Research continues to make HIV treatment feel less like a chore and more like living.

INTRODUCTION: Antiretroviral single-tablet regimens (STRs) have several advantages over multiple-tablet regimens (MTRs), including increased adherence and improved treatment satisfaction for people with HIV (PWH). This analysis has systematically reviewed and compared STRs and MTRs in adult PWH receiving integrase strand transfer inhibitor (INSTI)-based regimens. METHODS: MEDLINE and Embase databases were searched on November 28, 2023, to identify studies published from 2013 to 2023 that evaluated INSTI-based STRs compared with ≥ 1 INSTI-based MTRs. Study quality was assessed based on the University of York Centre for Reviews and Dissemination guidelines. Pairwise meta-analyses were conducted to provide pooled relative estimates for key clinical outcomes. RESULTS: Twenty-five publications were included in the quantitative syntheses. STRs were associated with improved adherence based on 3 retrospective studies [rate ratio (RR) = 1.64 (95% confidence interval: 1.46-1.83)] but there was no difference in adherence in the 1 randomized controlled trial (RCT) that assessed adherence [RR = 1.02 (0.77-1.35)], though, due to blinding, both STR and MTR groups took multiple pills. STRs were associated with higher persistence than MTRs based on 7 retrospective studies [RR = 1.33 (1.17-1.52)]. PWH treated with MTRs versus STRs were more likely to discontinue therapy in retrospective studies [hazard ratio = 1.62 (1.52-1.72), 6 studies] and prospective cohort studies [RR = 4.43 (1.62-12.09), 3 studies], but not within RCTs where there was no difference in discontinuation [RR = 0.83 (0.55-1.26), 4 trials]. Risk of virologic failure was comparable between STRs and MTRs in RCTs [RR = 1.00 (0.35-2.84), 5 trials] and retrospective studies [odds ratio = 1.30 (0.30-5.53), 5 studies]. CONCLUSION: INSTI-based STRs were associated with improved adherence and persistence, and lower discontinuation rates compared with INSTI-based MTRs in observational, real-world studies, whereas no differences in adherence or discontinuation were seen in RCTs. Neither RCTs nor real-world studies showed any difference in virologic failure for STRs and MTRs. STRs are a potential tool for supporting adherence and persistence in real-world settings.
