• HIV-1 Infection

Zidolam N 300mg/150mg/200mg Tablet is a combination of three antiretroviral medicines. Lamivudine and Zidovudine work by inhibiting the reverse transcriptase enzyme of HIV, restricting viral genome replication, and reducing the production of new infectious viral particles. It mainly interferes with reverse transcription and inhibits the spread of HIV. Nevirapine directly binds to reverse transcriptase (RT) and blocks RNA-dependent and DNA-dependent polymerase activities by disrupting the enzyme.

Certain medications, including ganciclovir, interferon alfa, and ribavirin, may exacerbate the toxicity of zidovudine interaction with Zidolam N 300mg/150mg/200mg Tablet and reduce its effectiveness by causing undesirable side effects.
