Stavudina Microsules
Stavudina Microsules Uses, Dosage, Side Effects, Food Interaction and all others data.
A dideoxynucleoside analog that inhibits reverse transcriptase and has in vitro activity against HIV.
Stavudina Microsules is a nucleoside reverse transcriptase inhibitor (NRTI) with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Stavudina Microsules is phosphorylated to active metabolites that compete for incorporation into viral DNA. They inhibit the HIV reverse transcriptase enzyme competitively and act as a chain terminator of DNA synthesis. The lack of a 3'-OH group in the incorporated nucleoside analogue prevents the formation of the 5' to 3' phosphodiester linkage essential for DNA chain elongation, and therefore, the viral DNA growth is terminated.

Uses
Stavudina Microsules is a dideoxynucleoside used in the treatment of HIV infection.
For the treatment of human immunovirus (HIV) infections.
Stavudina Microsules is also used to associated treatment for these conditions: Human Immunodeficiency Virus (HIV) Infections
How Stavudina Microsules works
Stavudina Microsules inhibits the activity of HIV-1 reverse transcriptase (RT) both by competing with the natural substrate dGTP and by its incorporation into viral DNA.
Toxicity
Side effects include peripheral neuropathy tingling, burning, numbness, or pain in the hands or feet), fatal lactic acidosis has been reported in patients treated with stavudine (ZERIT) in combination with other antiretroviral agents, severe liver enlargement, inflammation (pain and swelling) of the liver, and liver failure.
Food Interaction
- Avoid alcohol. Ingesting alcohol while taking stavudine may increase the risk of liver damage and pancreatitis.
- Take with or without food.
Stavudina Microsules Cholesterol interaction
[Major] The reverse transcriptase inhibitors, didanosine (ddI), zalcitabine (ddC), stavudine (d4T) and lamivudine (3TC), may cause pancreatitis.
The incidence is generally low but is approximately 7% with ddI, and up to 15% in pediatric patients given 3TC.
Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with these agents.
Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.
