fabrication of nanoparticles and thermosensitive hydrogel ...
Transporter-Targeted Prodrug Delivery to Improve Oral Bioavailability of Saquinavir
(2015-05-22)
Saquinavir (SQV) is the first antiretroviral protease inhibitor approved by Food and
Drug Administration in the United States for the treatment of HIV infection due to its
potent anti-HIV activity. However, some unfavorable ...
Novel in vitro cell culture models for studying pharmacokinetic drug-drug interactions following oral administration
(University of Missouri--Kansas City, 2011-09-21)
