Viral resistance emerges rapidly when delavirdine is used alone, so it is therefore used (as the methanesulfonic acid salt) with other antiretrovirals for combination therapy of HIV infection. It has a role as a HIV-1 reverse transcriptase inhibitor and an antiviral drug. It is a N-acylpiperazine, a sulfonamide, an aminopyridine and an indolecarboxamide."}]
