  | [[Atazanavir]] || Reyataz  || [[Bristol-Myers Squibb]] || - || The FDA approved it on June 20, 2003. Atazanavir was the first PI approved for once-daily dosing. It appears to be less likely to cause lipodystrophy and elevated cholesterol as side effects. It may also not be cross-resistant with other PIs.
  | [[Raltegravir]] || Isentress || [[Merck & Co.]] || - || also known as MK-0518. Raltegravir was approved by the FDA on October 12, 2007, for use with other anti-HIV agents in the treatment of HIV infection in adults. It is the first integrase inhibitor approved by the FDA.
|-
| [[Amprenavir]]  || Agenerase  || [[GlaxoSmithKline]] || {{US patent|5585397}} || The FDA approved it April 15, 1999, making it the sixteenth FDA-approved antiretroviral. It was the first protease inhibitor approved for twice-a-day dosing instead of needing to be taken every eight hours. The convenient dosing came at a price, as the dose required is 1,200 mg, delivered in eight very large gel capsules. Production was discontinued by the manufacturer December 31, 2004, as it has been superseded by fosamprenavir.

| [[Darunavir]]  || Prezista  || [[Tibotec]] || - ||  It was approved by the [[Food and Drug Administration]] (FDA) on June 23, 2006. Prezista is an [[OARAC]] recommended treatment option for treatment-naïve and  treatment-experienced adults and adolescents<ref name="oarac">Guidelines for the Use of Antiretroviral Agents in HIV-1-Infected Adults and Adolescents, November 3, 2008, Developed by the DHHS Panel on Antiretroviral Guidelines for Adults and Adolescents – A Working Group of the Office of AIDS Research Advisory Council (OARAC).

|  [[Fosamprenavir]]|| Lexiva, Telzir || [[GlaxoSmithKline]] || - || Is a [[prodrug]] of amprenavir. The FDA approved it October 20, 2003. The human body metabolizes fosamprenavir in order to form amprenavir, which is the active ingredient. That metabolization increases the duration that amprenavir is available, making fosamprenavir a [[slow-release]] version of amprenavir and thus reduces the number of pills required versus standard amprenavir.

| [[Indinavir]]  || Crixivan  || [[Merck & Co.]] || {{US patent|5413999}} || -

| [[Lopinavir]]  || Kaletra || [[Abbott Laboratories|Abbott]] || - || Is only marketed as a combination, with [[ritonavir]].

  | [[Nelfinavir]] || Viracept  || [[Agouron Pharmaceuticals]] || {{US patent|5484926}} || -
  | [[Elvitegravir]] || GS-9137 || [[Gilead Science]] || - || in experimental stages. Phase II studies of elvitegravir in people who are treatment experienced have been completed. Phase III studies in treatment experienced patients are ongoing. A phase II study of elvitegravir in people who have never taken antiretroviral therapy is underway. This study will also be evaluated a boosting agent in place of Norvir, currently called GS9350. Elvitegravir holds promise for HIV-positive patients who have taken other anti-HIV drugs in the past.
