Abstract The synthesis of pectin-silica gels for controlled drug release in gastrointestinal tract (GIT) using low methoxyl (LM) and high methoxy (HM) pectins and tetraethoxysilane (TEOS) as precursor is described. The FTIR spectra of the pectin-silica gels show intense absorption bands at 1246 cm−1 and 802 cm−1 corresponding to the vibrations single bondCsingle bondOsingle bondSisingle bond bonds, which absent in the FTIR spectra of the native pectins that indicate the formation covalent...

We investigated the feasibility of highly branched cyclic dextrin (HBCD) as an excipient matrix in dry powder inhalers (DPIs). The fine particles of HBCD and HBCD/active pharmaceutical ingredients (API) were prepared by spray-drying an ethanol-aqueous solution containing HBCD. More
