Information about Nelfinavir

Nelfinavir is an antiretroviral protease inhibitor used in the therapy and prevention of human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS).

Liver safety of Nelfinavir

Nelfinavir can cause transient and usually asymptomatic elevations in serum aminotransferase levels and is a rare cause of clinically apparent, acute liver injury. In HBV or HCV coinfected patients, hepatic injury during antiretroviral therapy that includes nelfinavir may be a result of exacerbation of the underlying chronic hepatitis B or C, rather than a direct effect of the medication.

Mechanism of action of Nelfinavir

Nelfinavir (nel fin' a vir) is a nonpeptidic protease inhibitor that acts by binding to the catalytic site of the HIV protease, thereby preventing the cleavage of viral polyprotein precursors into mature, functional proteins that are necessary for viral replication.

Nelfinavir was approved for use in the United States in 1997 for the therapy of HIV infection in both adults and children. Nelfinavir is available in tablets of 250 and 625 mg and as an oral suspension powder under the brand name Viracept.

Dosage and administration for Nelfinavir

The recommended dosage of nelfinavir for adults is 1250 mg twice or 750 mg three times daily.

Side effects of Nelfinavir

Common side effects include nausea, diarrhea, gastrointestinal upset, fatigue and, with long term use, hyperlipidemia and lipodystrophy.
