Although rectal and vaginal routes of drug delivery are not common, Kalliopi Dodou examines the design of new formulations that allow easier insertion and retention The rectum and vagina are relatively uncommon routes for drug administration. However, they can be ideal sites for drug delivery when it comes to certain diseases and patient groups. These stability-indicating methods are suitable to investigate the physicochemical stability of dexamethasone, hydrochlorothiazide, phenytoin, or spironolactone in compounded preparations. Moreover, these methods, easy to implement and rapid to perform, may be routinely used for QC testing in order to perform a batch release of such compounded Author: Guillaume Binson, Karine Beuzit, Virginie Migeot, Léa Marco, Barbara Troussier, Nicolas Venisse, Ant.   EXCIEPIENTS- functions Impart weight, accuracy, & volume(its allow acccuracy of dose) Improve solubility Increase stability Enhance bioavailability Modifying drug release Assist pdt identification Increase patient acceptability Facilitate dosage form design .

SUMMARY. Two tablet formulations of mg metronidazole were evaluated for their bioequivalence in twenty three healthy male volunteers (metronidazole, from EMS-Sigma Pharma, Brazil, as the test formu-lations versusFlagyl®from Rhodia, Brazil, as the reference formulation). The Pharmaceutical Journal 7 JUN By Kalliopi Dodou and Hamde Nazar Innovations in the design of oral formulations are driven by the need to target the site and monitor the time required for drug release, enhance the bioavailability of poorly soluble drugs, minimise dose dumping and prevent intentional or accidental misuse by patients.
