MedKoo CAT#: 412420

CAS#: 136777-48-5 (HCl)

Description: Abacavir hydrochloride is the salt form of Abacavir (ABC), an antiretroviral medication used to prevent and treat HIV/AIDS. It is of the nucleoside analog reverse transcriptase inhibitor (NRTI) type. Viral strains that are resistant to zidovudine (AZT) or lamivudine (3TC) are generally, but not always, sensitive to abacavir. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system. It is available under the trade name Ziagen and in the combination formulations abacavir/lamivudine/zidovudine, abacavir/dolutegravir/lamivudine, abacavir/lamivudine.
