**Abstract** Nanocrystals have emerged as a transformative approach in HIV therapy, addressing key challenges in drug delivery and efficacy. These submicron particles enhance the solubility and bioavailability of poorly water-soluble antiretroviral drugs, improving therapeutic outcomes. Nanocrystals facilitate targeted delivery, ensuring sustained drug release and reducing dosing frequency, which can enhance patient adherence. Additionally, their ability to penetrate biological barriers, such as the blood-brain barrier, provides an advantage in eradicating latent HIV reservoirs. Recent studies demonstrate that nanocrystal formulations can minimize systemic toxicity and drug resistance by maintaining consistent drug levels in plasma and tissues. Their versatility allows for incorporation into oral, injectable, and topical formulations. Despite promising preclinical and clinical results, challenges such as large-scale production, stability, and regulatory considerations need to be addressed. This review highlights the potential of nanocrystals as a game-changing tool in HIV therapy, offering new avenues for improving treatment efficacy and quality of life for patients.
