Hiv

Although several different types of drugs are used by patients with AIDS to treat their human immunodeficiency virus (HIV) infection (usually in combination), until recently no drug has received full approval from the FDA based on long-term results. In February 2000, Sustiva (efavirenz), manufactured by DuPont Pharmaceuticals, became the first anti-HIV drug to receive full FDA approval based on long-term data supporting its effectiveness in fighting HIV infection.
