Clinicians who manage tuberculosis are quite familiar with the difficulties entailed in keeping an appreciable number of their patients on an uninterrupted, pro...

Acrylic type polymeric systems having degradable ester bonds linked to the 5-aminosalicylic acid (5-ASA), were synthesized and evaluated for colon targeted drug delivery. The obtained prodrug was characterized by FTIR,HNMR,Melting point and Rf value.In vitro drug release study was conducted at pH 1.2,7.4 and in rat fecal matter. Drug release in rat fecal matter at pH 7.4 was found to be most sa...

The reaction between the high-dose drug substance 5-aminosalicylic acid (5-ASA) and the excipient citric acid during storage of an experimental enema preparation has been studied and three isobaric reaction products, i.e., an ester and an amide with non-symmetrically substituted citric acid moieties and a symmetrical amide, were identified by combined use of HPLC-SPE-NMR and HPLC-MS. After stor...
