Experimental treatment approaches

Over the past two decades, HIV treatment has evolved from AZT (zidovudine, Retrovir) monotherapy to the current standard of care – highly active antiretroviral therapy (HAART) consisting of combination regimens that include three or more drugs from at least two different classes.
