Abstract

Over the recent past, many of the research groups are focusing their research on Fast Dissolving Dosage forms technology. However some patients, particularly pediatric and geriatric patients, have difficulty in swallowing or chewing solid dosage forms or willing to take these solid preparations due to fear of choking. The main advantages of FDOF'S are towards pediatric and geriatric patients population. Where the difficulty of swallowing a larger oral dose is a main problem. This technology has been used for local action, rapid release products and for bucoadhesive systems that are retained for longer period in the oral cavity to release drug in controlled fashion. FDOF offers an alternate platform for molecules that undergo first pass metabolism and for delivery of peptides.

The aim of this study was to develop an innovative Fast Dissolving oral film of (FDOF) of Perindopril. The new dosage form was obtained by solvent casting method using polymers such as Hydroxy propyl methyl cellulose and polyethylene glycol, chitosan. A various concentration of polymers was conducted in order to optimize API concentration of the new dosage form. The FDOF was characterized for weight, thickness, folding endurance and dissolution using invitro experimentations. The effect of HPMC and PEG on drug release profile and film forming properties was investigated. The prepared films exhibited satisfactory physic-chemical characteristics. Finally, it is concluded that Perindopril can be formulated with HPMC, chitosan and PEG polymers to achieve oral film formulation by using solvent casting method.

Abstract

A simple, fast, precise, selective and accurate RP-HPLC method was developed and validated for the simultaneous determination of Ketorolac tromethamine and olopatadine HCl from bulk and formulations. Chromatographic separation was achieved isocratically on a Inertsil ODS C18 column (250×4.6 mm, 5 μ particle size) using a mobile phase 0.1 M Sodium di hydrogen orthophosphate: Acetonitrile in the ratio of 55:45. The flow rate was 1 ml/min and effluent was detected at 235nm. The retention time of Ketorolac and olopatadine were 2.507 min and 4.933 min. respectively. Linearity was observed in the concentration range of 4-24μg/ml and 12-72μg/ml for Ketorolac and olopatadine respectively with correlation coefficient of 0.999 for both the drugs. Percent recoveries obtained for ketorolac and olopatadine were 100.03% and 100.04%, respectively. The method was validated according to the ICH guidelines with respect to specificity, linearity, accuracy, precision and robustness. The method developed can be used for the routine analysis of Ketorolac and olopatadine from their combined dosage form.

Abstract

A simple, fast and precise stability indicating RP - HPLC method was developed for the quantification of Memantine HCl in pure and pharmaceutical dosage form. The quantification was carried out using Intersil ODS C18 4.6 X 150mm, 5μm enhanced polar selectivity column and mobile phase comprised of 0.2M sodium dihydrogen phosphate&0.1M disodium hydrogen phosphate buffer of pH adjusted to 3 with orthophosphoric acid and Acetonitrile in proportion of ratio 50:50 and degassed under ultrasonication. The flow rate was 1ml/min and the effluent was monitored at 272nm. The retention time of Memantine HCl was found to be 3.337 min. The method was validated in terms of linearity, precision, accuracy, specificity, robustness, limit of detection and limit of quantitation in accordance with ICH guidelines. Linearity of Memantine was in the range of 20 - 120 μg/mL. The percentage recoveries of Memantine were 99.66% to 102.5% from the tablet formulation. The stability - indicating capability was established by forced degradation experiments. The proposed method is suitable for determination of Memantine HCl in pharmaceutical dosage form.
