Drugs Supplied by NACO For Prevention of Mother to Child transmission
**Core Concept**
The prevention of mother-to-child transmission (PMTCT) of HIV involves the use of antiretroviral drugs to prevent the transmission of the virus from an HIV-positive mother to her child during pregnancy, childbirth, and breastfeeding. The National AIDS Control Organization (NACO) plays a crucial role in providing these drugs to pregnant women living with HIV in India.
**Why the Correct Answer is Right**
NACO supplies antiretroviral therapy (ART) regimens, specifically the Option B+ regimen, which consists of tenofovir, lamivudine, and nevirapine. This regimen is recommended for all pregnant women living with HIV, regardless of their CD4 count or WHO clinical stage. The use of ART during pregnancy significantly reduces the risk of mother-to-child transmission of HIV by reducing the viral load in the mother's blood.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because NACO does not supply AZT (zidovudine) as a single drug for PMTCT.
* **Option B:** This option is incorrect because NACO does not supply Lopinavir/Ritonavir as a standalone regimen for PMTCT.
* **Option C:** This option is incorrect because NACO does not supply Efavirenz as a first-line option for PMTCT.
**Clinical Pearl / High-Yield Fact**
The Option B+ regimen is a highly effective and recommended approach for PMTCT in resource-limited settings. It is essential for healthcare providers to be aware of the NACO guidelines and to ensure that pregnant women living with HIV receive the recommended ART regimen to prevent mother-to-child transmission of HIV.
**Correct Answer:** C.
