ABSTRACT

The objective of the present investigation is to formulate gastroretentive dosage form of Nizatidine, a H2-receptor antagonist widely prescribed in gastric ulcers, duodenal ulcers. The short biological half-life (1 - 2 hours), maximum absorption in initial part of small intestine, colonic metabolism of Nizatidine favors’ development of gastro retentive floating dosage form. In the present study Nizatidine floating tablets were prepared by effervescence method using sodium bicarbonate as a gas generating agent. The tablets were formulated using direct compression technology by employing semi synthetic polymers like various grades of HPMC such as HPMC K4M, K15M, K100M and natural polymers like xanthan gum and kondagogu gum. drug-excipient compatible studies by FTIR and DSC , The FTIR and DSC study revealed that there is no drug-excipient interaction. The prepared tablets were evaluated for various physicochemical parameters such as flow properties, hardness, weight variation, friability, in vitro buoyancy (floating lag time, total floating time), swelling studies, drug content and in-vitro drug release. The in vitro drug release pattern of Nizatidine floating tablets was fitted to different kinetic models which showed highest regression for zero order kinetics with non fickian diffusion mechanism. Out of all formulations the one prepared with combination of HPMC K4M and K15M was optimized based on desired sustained release time (12hrs) and acceptable floating properties.

Abstract Acne is an inflammatory disease of sebaceous follicles of skin. The present study was conducted to formulate and evaluate the topical anti acne formulation of coriander oil and coriander aqueous extract with and without penetration enhancer. Then these formulations were compared with each other to establish the effect of penetration enhancer. The antibacterial activity of Coriander oil and aqueous extract against Propionibacterium acne (P.acne) and Staphylococcus epidermidis (S.epidermidis) was investigated by disc diffusion method and Minimum inhibitory concentration (MIC) by agar dilution method. The topical formulations were developed separately without penetration enhancer (menthol) and further two formulations were developed separately with penetration enhancer. These formulations were subjected to the drug content uniformity, invitro diffusion and skin permeation studies. The results showed that coriander oil possesses greater potency as compared to the aqueous extract as the MIC values of 1%v/v and 1.1%v/v were obtained for oil against P.acne and S. epidermidis respectively. The incorporation of penetration enhancer resulted in the formulations with increased drug content, invitro release and permeation. The statistical analysis showed that menthol incorporation led to the significant increase in the permeation of both types of formulations. All the formulations followed the first order release and higuchi model was found to be the most suitable one.

Abstract

Diabetes mellitus is a group of metabolic disorder in which a person has high blood sugar because either the body does not produce enough insulin or because cells do not respond to the insulin. Targeted drug delivery for the treatment of Diabetes using nanotechnology is one of the recent advances in nanomedicine. Polymeric nanoparticles, either natural or synthetic have been used as matrices for oral antidiabetic drug delivery. Natural polysaccharides, due to their outstanding merits, have received more and more attention in the field of drug delivery systems. In particular, polysaccharides seem to be the most promising materials in the preparation of nanometeric carriers. The natural polyelectrolyte polysaccharides polymers mainly used for oral anti diabetic drug delivery, positive polyelectrolyte polysaccrides is widely explored owing to its ease of chemical modification and favorable biological properties. In addition, many advantages such as safety, biodegradability, widespread availability and low cost justify the continuing development of promising hypoglycemic drug delivery system. This manuscript palpably discusses the polyelectrolyte polysccrides polymeric nanoparticles drug delivery systems in the treatment of diabetes.
