A drug dosage form is very important in delivering the drug in proper dose in most appropriate form. The capsule shell is an excellent barrier to air, and it also has some other advantages such as being easy to swallow and tasteless, flexibility of formulation etc. The use of the hard gelatin capsule dosage form may perhaps be an alternative to overcome the problem, which the hygroscopicity of the extracts may pose. Present study was envisaged to develop a polyherbal formulation as capsule. The results obtained by the thermo analytical techniques showed no chemical incompatibility between capsule shell and herbal extract. The results were further confirmed by IR spectroscopy. The herbal capsule was stored at different temperatures viz., 25 0C, 40 0C and 50 0C for shelf life evaluation. The percentage alkaloid content for day zero was taken as 100% and accordingly, the percentages were calculated for all the other days. The organoleptic properties of the herbal capsule remain unchanged at tested temperatures throughout the stability study. Likewise, pH...

Quality by Design [QbD] is a science based approach widely used in industry to continually monitor and improve the quality of product. It is a modern risk based strategic framework of all the aspects related to quality. ICH guidelines Q8 to Q11 summarizes all the different perspectives of quality by design system in required depth along with ways to implement it. This review in all focuses on the general terms of QbD its meanings and application along with different wide range applications of the QbD to pharmaceutical fields like Analysis, Formulation, Design and Technology development, Control Strategies etc. Also it includes a short view over the application of Various QbD tools like PAT, CAPA and HACCP in Pharmaceutical industry along with their importance in the Quality aspect of Pharmaceutical products. It also tries to cover the major aspects to be concerned while selecting the wide ranges of designs and statistical tools while employing QbD to a Particular aspect of Pharmaceutical...

This paper describes a new, simple, precise, and accurate HPTLC method for simultaneous estimation of Oxyclozanide and Levamisole hydrochloride as the bulk drug and in tablet dosage forms. Chromatographic separation of the drugs was performed on aluminium plates pre-coated with silica gel 60 F254 as the stationary phase and the solvent system consisted of Toluene: acetone: ammonia (5:5:0.04 v/v/v). Densitometric evaluation of the separated zones was performed at 225 nm. The two drugs were satisfactorily resolved with R F values 0.28± 0.007 and 0.49 ± 0.009 for Oxyclozanide and Levamisole hydrochloride, respectively. The accuracy and reliability of the method was assessed by evaluation of linearity (400-1200 ng/band for Oxyclozanide) and (200-600 ng/band for Levamisole hydrochloride), precision (intra-day % RSD was 1.20 and inter-day % RSD was 1.51 for Oxyclozanide, and intra-day % RSD was 1.22 and inter-day % RSD was 1.52 for Levamisole hydrochloride), accuracy (0.556 for Oxyclozanide and 1.31 for Levamisole hydrochloride), and specificity in accordance with ICH...

In recent years more people throughout world are turning to use medicinal plant products in healthcare system. Worldwide need of alternative medicine has resulted in growth of natural product markets and interest in traditional systems of medicine. Proper integration of modern scientific techniques and traditional knowledge is important. There is a growing focus on the importance of medicinal plants in the traditional health care system (viz. Ayurveda, Unani, Homoeopathy, Yoga) in solving health care problems. Systematic approach and well-designed methodologies for the standardization of herbal raw materials and herbal formulations are developed. The stability testing of herbal products check the quality of herbal products which varies with the time under the influence of environmental factors, such as temperature, humidity, light, oxygen, moisture, other ingredient or excipient in the dosage form, particle size of drug, microbial contamination, trace metal contamination, leaching from the container, etc. and also provide statistics for the determination of shelf lives. Therefore evaluation of the parameters based upon chemical, physical, microbiological, therapeutic and toxicological studies can...

Retinoids are the derivatives of Vitamin A and have similar action to that of Vitamin A. Sources of Vitamin A such as eggs and meat are known to contain a chemical, retin-A which is known to be useful for treating various dermatological disorders. Tretinoin, a first generation retinoid was first used orally for the treatment of acne in 1940s. Topical tretinoin was later developed as a result of potential adverse effects when given orally and it showed promising therapeutic effect for keratinizing disorders such as actinic keratosis and ichthyosis. Other systemic retinoids such as isotretinoin, acitretin and bexarotene were also studied consecutively which gained approval from US-Food and Drug Administration for a number of keratinisation disorders like acne vulgaris, psoriasis and mycosis fungoides respectively. Along with these disorders, systemic retinoid are widely used for various off label dermatological conditions but due their potentially serious adverse effects, their use has been contraindicated in a number of conditions, especially for pregnant women where it is reported to cause serious embryo-foetal abnormalities....
