WebJan 10, 2024 · However, for the high-dose sustained-release preparations, solubilization strategies such as salt formation and nanotechnology should be applied to increase the solubility in the intestine. RS-carvedilol has lower solubility at pH 1.2–5.0 and higher solubility at pH 6.0–8.0 compared with S-carvedilol or R-carvedilol. WebSep 1, 2024 · For poorly soluble drugs, drug absorption can be limited by the dissolution rate or the solubility of the drug in gastrointestinal fluids (Amidon et al., 1995). If this is the case, in vitro release and dissolution testing can be used as surrogate for a drug's in vivo performance (Amidon et al., 1995).
