Polyelectrolyte Complexes of Partially Betainated Chitosan Derivatives Soluble in Weakly Alkaline Media
The design of biologically active dosage forms based on chitosan is significantly limited by its insolubility at pH values above 6.0–6.5 and worsening of its gastrointestinal absorption capacity upon transition to neutral and alkaline environmental conditions. The partial acylation of short-chain ch...
