Didanosine Aurobindo (Didanosine)
Didanosine Aurobindo (Didanosine) Uses, Dosage, Side Effects, Food Interaction and all others data.
A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. Didanosine Aurobindo (Didanosine) is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA by binding to reverse transcriptase; ddI is then metabolized to dideoxyadenosine triphosphate, its putative active metabolite.
Didanosine Aurobindo (Didanosine) is a nucleoside reverse transcriptase inhibitor (NRTI) with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Didanosine Aurobindo (Didanosine) is a hypoxanthine attached to the sugar ring, unlike other nucleoside analogues. Didanosine Aurobindo (Didanosine) 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. Didanosine Aurobindo (Didanosine) is effective against HIV, and usually used in combination with other antiviral therapy. Switching from long term AZT treatment to didanosine has been shown to be beneficial. Didanosine Aurobindo (Didanosine) has weak acid stability and therefore, it is often combined with an antacid.

Uses
Didanosine Aurobindo (Didanosine) is a reverse transcriptase inhibitor used to treat HIV.
For use, in combination with other antiretroviral agents, in the treatment of HIV-1 infection in adults.
Didanosine Aurobindo (Didanosine) is also used to associated treatment for these conditions: Human Immunodeficiency Virus Type 1 (HIV-1) Infection
How Didanosine Aurobindo (Didanosine) works
Didanosine Aurobindo (Didanosine) (ddI) is metabolized intracellularly by a series of cellular enzymes to its active moiety, dideoxyadenosine triphosphate (ddATP), which inhibits the HIV reverse transcriptase enzyme competitively by competing with natural dATP. It also acts as a chain terminator by its incorporation into viral DNA as 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.
Toxicity
Side effects include pancreatitis, peripheral neuropathy, diarrhea, hyperuricemia and hepatic dysfunction
Food Interaction
- Avoid alcohol.
- Take on an empty stomach. Take at least 1 hour before or 2 hours after meals.
[Moderate] ADJUST DOSING INTERVAL: Didanosine Aurobindo (Didanosine) bioavailability is decreased when administered with food.
Loss of efficacy may result.
MANAGEMENT: Didanosine Aurobindo (Didanosine) should be administered in the fasting state, at least 30 minutes before or more than 2 hours after eating.
Didanosine Aurobindo (Didanosine) 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.
Didanosine Aurobindo (Didanosine) Hypertension interaction
[Moderate] Didanosine Aurobindo (Didanosine) (ddI) formulations have a high sodium content.
There are 265 mg of sodium per tablet and 1380 mg per packet of powder for oral solution, which may be of concern in patients with conditions that may be adversely affected by excessive amounts of sodium, such as congestive heart failure, hypertension, and fluid retention.
Each tablet also contains 8.6 mEq of magnesium.
Patients with significant renal impairment may not tolerate these loads.

Didanosine Aurobindo (Didanosine) Disease Interaction
Major: renal dysfunction, bone marrow suppression, hepatotoxicity, pancreatitis, peripheral neuropathyModerate: hyperuricemia, PKU, sodium
Elimination Route
Rapidly absorbed (bioavailability 30-40%) with peak plasma concentrations appearing within 0.5 and 1.5 hrs.
Half Life
30 minutes in plasma and more than 12 hours in intracellular environment.
Elimination Route
Based on data from in vitro and animal studies, it is presumed that the metabolism of didanosine in man occurs by the same pathways responsible for the elimination of endogenous purines. Purines are eliminated by the kidneys.
