"Improving HIV-1 Protease Inhibitor May Be Feasible"
Reuters Health Information services (01/15/98)
Researchers at Vanderbilt University claim that the
bioavailablity of HIV-1 protease inhibitors may be boosted by
inhibition of P-glycoprotein, a multidrug transporter. In the
January issue of the Journal of Clinical Investigations, the
researchers suggest that HIV-1 protease inhibitors, which have
limited oral absorption and variable tissue distribution, may be
P-glycoprotein substrates. Testing indinavir, nelfinavir, and
saquinavir in an in vitro system, the researchers found that all
three compounds are transported by P-glycoproteins. According
tothe researchers, targeted pharmacologic inhibition of
P-glycoprotein transport activity may allow for higher
concentrations of HIV-1 protease inhibitors.
