Abstract This study aimed to develop a mucoadhesive polymeric excipient comprising curcumin for buccal delivery. Curcumin encompasses broad range of benefits such as antioxidant, anti-inflammatory, and chemotherapeutic activity. Hyaluronic acid (HA) as polymeric excipient was modified by immobilization of thiol bearing ligands. L-Cysteine (SH) ethyl ester was covalently attached via amide bond formation between cysteine and the carboxylic moiety of hyaluronic acid. Succeeded synthesis was...

The biopharmaceutical studies have undoubtedly proven that pharmacopoeial excipients based on polyethylene oxide, sodium carboxymethyl cellulose and apple pectin can release pharmacologically active substances and produce pharmacopoeial excipients in the form of ointments and pastes. The dynamics of diffusion of biologically active substances in agar gel within 6 hours of the experiment was practically the same in all samples. The least significant changes in samples consistency and...

The purpose of this study was to investigate the influence of different hydrophilic polymers on the swelling, bioadhesion and mechanical strength of hydrocolloid wound dressings (HCDs) in order to provide an appropriate composition for a hydrocolloid wound dressing system. In this study, the HCDs were prepared with styrene-isoprene-styrene copolymer (SIS) and polyisobutylene (PIB) as the base using a hot melting method. Additionally, numerous SIS/PIB-based HCDs were prepared with six...
