background & aim : the process of delivery, from physiologic point of view, is similar to long exercises and decrease in physical activities is so common during pregnancy which could cause disruptions in the process of delivery. the present study aimed to determine the effects of exercise on childbirth process among primigravid women. methods & materials : this single-blind randomized clinical ...

Natural polymers are widely used in pharmaceutical formulations. They are biodegradable and generally nontoxic in nature. In this review pharmaceutical application of rosin is characterized. Rosin is a natural non-volatile resinous mass obtained from Pinus palustris. Physico-chemical characteristics and ease of availability of rosin provide a platform to use it as a polymer for different drug d...

conclusions this study demonstrated that physicochemical properties, in vitro release and rat intestine permeability were dependent upon the contents of s/c, water and oil percentage in formulations. background self-emulsifying drug delivery system is an isotropic mixture of natural or synthetic oils, non-ionic surfactants or, one or more hydrophilic solvent and co-solvents/surfactant and polym...

This review deals with the targeting of drugs to the lower gastrointestinal tract i.e. colon. Colonic drug delivery becomes important for localized action as well as for improved systemic availability of peptide and proteins. Drugs which have absorption window in the colonic region have been targeted using different novel technologies. pH sensitive polymers and prodrug based formulation have be...
