For 5 and 6 MeV, there are 1.7% and 1.5% discrepancies between TG 51 and TG 21, and -1.6% and 1.7% between TG 51 and JJG1026 91. Conclusions:The new protocol is more accurate and convenient because of its precise rationale and concise formulae.

Nevirapine ( NVP) is the first-generation non-nucleoside reverse transcriptase inhibitor, which is a front-line drug for the treatment of AIDS and the prevention of mother-to-child transmission of HIV-1. NVP is with poor solubility and low bioavailability. With the development of new dosage forms, such as solid dispersion, self-emulsifying, microparticles, micelles, sustained-release tab-lets and floating microspheres, the bioavailability of NVP can be increased and the adverse reactions can be decreased. Research pro-gress in the new dosage forms of NVP at home and abroad was reviewed through searching literatures in order to provide basis for the development of new dosage forms of NVP.
