Zidine tablets are co administration with tablets which containing an active composition known as zidovudine as an anti-retroviral medications and is combine with other anti-retroviral drugs for better activity. Patients administrating Zidine tablets treatment should have better able to attach to multiple drug treatment drugs, thereby developing the compliance.

The mechanism of action of zidovudine is also similar to lamivudine, like prohibition of viral reverse transcriptase by zidovudine triphosphate which is an active molecule of zidovudine. At last viral DNA chain ends occurs.


Absorption: Quickly absorps and peak plasma level of Zidine is 0.5 to 1.5hours;
Distribution: Highly distributed in body. The fundamental of Zidine tablets are binding to human plasma protein with the range of <38% for zidovudine. The binding serum ratio of Zidine is less.
Metabolism :
Zidovudine is go through metabolism by glucoronide conjugation.
Excretion :
Route of elimination of zidovudine is urine 29%; excreted as zidovudine metabolite 45%. The zidovudine half life period of is 0.5 to 3 hours.

The possible adverse occurred during or after completion of therapy with Zidine.

Hematological toxic

In case of neutropenia or thrombocytopenia, Zidine treatment should be postponed. Periodic blood cells count should be taken.
Lactic acidosis or hepatomegaly with steatosis :
This condition may leads to produce fatal cases, majorly in women. The most common adverse effect is obesity In severe condition treatment should be discontinued.
Myopathy :
In HIV-1 infected patients who are receiving Duovir having a chance of getting myopathy. The prolonged use of zidovudine is responsible for onset of myopathy in patients.

Drugs which are opposing the activity of zidovudine; The interaction of zidovudine with some drugs produces antagonist effects, like Stavudine Doxorubicin Nucleoside analogues like ribavirin Concurrent use with ribavirin, Ganciclovir, interferon alfa or other drugs may elevate the hematological toxicity effect of zidovudine. Avoid this concomitant treatment. Zidine should not be interact with Zalcitabine which may changes or prohibits the intracellular phosphorylation of one another.


The patient are contraindicated to the component present in Zidine tablets then Anaphylactic reaction may occur


The over dosage of Zidine should be treated by undergoing hemodialysis. Hemodialysis helps to remove the content of zidovudine from the body. Provide supportive measures.
