Nanotechnology-based systems for the treatment and prevention of HIV/AIDS.
The HIV/AIDS pandemic is an increasing global burden with devastating health-related and socioeconomic effects. The widespread use of antiretroviral therapy has dramatically improved life quality and expectancy of infected individuals, but limitations of currently available drug regimens and dosage forms, alongside with the extraordinary adapting capacity of the virus, have impaired further success. Circumventing the escalating number of new infections can only be attained with effective and practical preventive strategies. Recent advances in the field of drug delivery are providing evidence that engineered nanosystems may contribute importantly to the enhancement of current antiretroviral therapy. Additionally, groundwork is also being carried out in the field on nanotechnology-based systems for developing preventive solutions for HIV transmission. This manuscript reviews recent advances in the field of nanotechnology-based systems for the treatment and prevention of HIV/AIDS. Particular attention is given to antiretroviral drug targeting to HIV reservoirs and the usefulness of nanosystems for developing topical microbicides and vaccines.
