What is Viraday used for?
Viraday tablets are a fixed dose combination treatment for Human Immunodeficiency Virus (HIV) infection in adults over age 18. Viraday tablets are used to treat HIV patients who have already received treatment with other HIV medications and have responded to all medications prescribed; they can also be used alone as monotherapy or in combination with other HIV medications. HIV impairs the immune system by attacking specific immune cells called CD4+ cells that are involved in fighting infection, which can lead to opportunistic life-threatening infection (infections that would not normally be harmful); also if too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS). Viraday tablets prevent or slow down the ability of HIV to replicate and spread, which keeps the amount virus down to a low level and this results in an increase in CD4 cell numbers, so that the immune system can recover, reducing the risk of disease progression.
How does Viraday work?
Viraday tablets contain a combination of three antiretroviral drugs, efavirenz, emtricitabine and tenofovir disoproxil fumarate, which are only effective against RNA viruses (retroviruses) like Human Immunodeficiency Virus (HIV). These three drugs each work by inhibiting the action of the viral-specific enzyme reverse transcriptase (RT) which is needed for the virus to be able to replicate.
