Long-Acting HIV Prevention refers to an injectable form of antiretroviral drugs that can provide protection against HIV for several weeks or months, thereby reducing the need for daily oral administration.
It addresses the adherence issue associated with daily oral PrEP (Pre-Exposure Prophylaxis), which is critical for maintaining efficacy but can be challenging for some individuals to adhere to consistently.
The injectables contain long-acting formulations of antiretrovirals which are slowly released over time. This sustained release allows for a single injection to deliver therapeutic levels of medication over an extended period, typically every few weeks or months depending on the specific formulation and regimen used.
The manufacturing process involves developing a stable, long-acting formulation of antiretrovirals that can be administered via injection. This includes optimizing drug release mechanisms and ensuring the injectable formulation remains effective over extended periods without degradation.
Development typically involves preclinical testing to assess safety and efficacy, followed by clinical trials to validate these findings in human subjects. The process also requires regulatory approval before widespread use can be implemented.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking processes required for certain formulations.
