Nelfinavir, sold under the brand name Viracept, is an antiretroviral medication used in the treatment of HIV/AIDS. Nelfinavir belongs to the class of drugs known as protease inhibitors (PIs) and like other PIs is almost always used in combination with other antiretroviral drugs. Nelfinavir is an orally bioavailable human immunodeficiency virus HIV-1 protease inhibitor (Ki = 2 nM) and is widely prescribed in combination with HIV reverse transcriptase inhibitors for the treatment of HIV infection.It was patented in 1992 and approved for medical use in 1997. Toxicity
Common (>1%) side effects include insulin resistance, hyperglycemia and lipodystrophy.Nelfinavir can produce a range of adverse side effects. Flatulence, diarrhea, or abdominal pain are common (i.e. experienced by more than one in one hundred patients). Fatigue, urination, rash, mouth ulcers, or hepatitis are less frequent effects (experienced by one in one thousand to one in one hundred patients). Nephrolithiasis, arthralgia, leukopenia, pancreatitis, or allergic reactions may occur, but are rare (less than one in one thousand patients) . Other bioactivity
Antiviral
Nelfinavir inhibits maturation and export of the herpes simplex 1 virus and the Kaposis sarcoma virus. Anti-virulence activity
Nelfinavir and simple derivatives have been found to inhibit the production of the virulence factor streptolysin S, a cytolysin produced by the human pathogen Streptococcus pyogenes. Nelfinavir and these related molecules did not exhibit detectable antibiotic activity, but did also inhibit the production of other biologically active molecules, including plantazolicin (antibiotic), listeriolysin S (cytolysin), and clostridiolysin S (cytolysin), by other bacteria. Interactions
Nelfinavirs interaction profile is similar to that of other protease inhibitors.
Isoniazid/rifampicin, also known as isoniazid/rifampin, is a medication used to treat tuberculosis. It is a fixed dose combination of isoniazid and rifampicin (rifampin). It is used together with other antituberculosis medication. It is taken by mouth.It is on the World Health Organizations List of Essential Medicines. Adverse effects and safety
Side effects are those of the underlying medications. Common side effects include poor coordination, poor appetite, nausea, numbness, and feeling tired. More severe side effects include liver problems. Use is generally not recommended in children. It is unclear if use is safe in pregnancy. == References ==
