The combined anti-HIV-1 activities of emtricitabine and tenofovir plus the integrase inhibitor elvitegravir or raltegravir show high levels of synergy in vitro.

abstract：:Because of the widespread occurrence of resistance to sulfonamides among Enterobacteriaceae, some researchers have suggested using trimethoprim (TMP) alone instead of the combination sulfamethoxazole-trimethoprim (SMX-TMP) in treating infections with TMP-susceptible organisms. To answer whether SMX-TMP suppresses the ...
