Orally disintegrating drug delivery is currently the gold standard in the pharmaceutical industry where it is regarded as the fastest, safest, convenient, and most economic method of drug delivery having the highest patient compliance and preferred over conventional tablets. The goal of this study was to formulate and evaluate oral disintegrating tablets (ODTs) of Metoclopramide hydrochloride to overcome swallowing difficulties. The key to developing successful ODT formulation by direct compression method is to select the right super disintegrant. Nine formulations were prepared using different super disintegrants such as sodium starch glycolate (SSG), croscarmellose sodium (CCS), and crospovidone (CP) at three concentrations i.e. 2.8 %, 4 %, and 4.8 %. The formulation was evaluate for pre and post-compression parameters like angle of repose, compressibility index, Hausner's ratio, uniformity of content, thickness, hardness, friability, drug content, wetting time, water absorption ratio, dispersion time, in-vitro disintegration time etc. Results revealed that among the 9 formulations, the formulation MHF9 containing 4.8 % of crospovidone was selected as the best formulation as its wetting time 28 second, disintegration and dispersion time 7 second and 18 seconds, percentage drug release after 15 minutes was 102.52 %.
Dry eye is ubiquitous but under diagnosed ocular morbidity. Many people didn't recognize or refuse this ocular morbidity due to inadequate knowledge, but now our understanding of DED has improved dramatically over the last 20 years with advancements in research .Dry eye disease is multifactorial disease of tear film and ocular surface that result in discomfort, visual disturbance and tear film instability with possible damage to ocular surface. Tear film is a complex mixture of substance secreted from the multiple sources on the ocular surface, including lacrimal gland, meibomian glands and goblet cells. As the population ages, the prevalence of dry eye is likely to increase, yet the condition is often underrecognized and undertreated. This comprehensive review article describes our current knowledge and understanding of the causes and interprets the detail information on definition, prevalence, etiology, classification, diagnostic test, and method of management of dry eye disease. This paper also discusses on ongoing researches, current challenge and future directions for advancing knowledge and treatment of the condition. Via this comprehensive review, in the light of our current understanding of DED, we aim to provide awareness among the patients, health care professionals, researchers, and especially among them who are at major risk for developing DED about diagnosis and treatment of DED and recent developments and future challenges in management of dry eye disease. Beside these, we have also stressed on lifestyle changes and dietary behaviors that may affect the tear dynamics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
