Sustained Release of Naltrexone from Poly(N‐Isopropylacrylamide) Microgels [PDF]

Journal of Pharmaceutical Sciences, 2014
The release of the opioid antagonist naltrexone from neutral poly(N-isopropylacrylamide) (PNIPAAM) microgels and negatively charged PNIPAAM microgels containing acrylic acid groups (PNIPAAM-co-PAA) has been studied at various microgel and drug concentrations. The release curves were found to be well represented by the Weibull equation.
