In recent years, performance measurement and metrics of organizations have received much attention from researchers and practitioners. The role of these measures and metrics in the success of an organization cannot be overstated because they affect strategic, tactical and operational planning and control. Performance measurement and metrics have an important role to play in setting objectives, evaluating performance and determining future courses of actions. Performance measurement and metrics pertaining to leagile supply chains have not received adequate attention from researchers or practitioners. In the area of supply chain management, application of MCDM methods is limited to supplier selection and transportation carrier selection.
In this paper, fifteen organizations involved in production of apparels in Telangana and Andhra Pradesh are considered for evaluation of supply chain strategies in leagile perspective using DEMATEL-AHP methodology. AHP frame work is developed with level 0 as goal of analyzing the leagile performance of the supply chains. Performance measures are considered in level 1. Level 2 contains enablers of the performance measures of leagile supply chains. Level 3 contains fifteen supply chain organizations. Weights of the performance enablers are determined through FPIR and FNIR approach without interdependence. DEMATEL is employed to determine the relative weights of the performance enablers from interdependence. DEMATEL is employed to determine the relative weights of the performance enablers from interdependence. Global weights of performance enablers are determined by successively multiplying the weights of performance measures with the weights respective enablers. Evaluation of supply chains in leagile perspective is done by finding out leagile index obtained by weighted sum of payoff of the enablers.

The objective of the present study was to develop an immediate release tablet of Dasatinib using different concentrations of cross carmelose sodium (CCS) as superdisintegrant with a view to gain rapid disintegration in gastric pH for treatment of chronic myeloid leukemia (CML) and acute myeloid leukemia (AML).Five different formulations of Dasatinib immediate release tablets were prepared using wet granulation method. Different pre compression and post compression characterization of tablet was carried out. In vitro drug release studies were carried out in USP II paddle type dissolution apparatus for different formulation and the batch containing 5% CCS gave maximum amount of drug release of 99.14%.Drug and excipients compatibility studies were carried out through FTIR spectroscopy. FTIR spectroscopy studies reveled that there is no interaction between drug and different excipients used in formulation. Short term stability studies (at 40±2°C/75±5% RH) on the best formulation indicated that there no significant changes in drug content.Keywords

The present work was aimed to develop controlled release tablets of aspirin. Direct compression technique was adopted for the preparation of all these formulations. The developed tablets were evaluated for pre compression parameters; post compression parameters, in vitro dissolution study. Among all the developed batches ASF3 showed highest drug release 96.14% at the end of 10 h. The optimized formulation was found to be stable up to 3 months when tested for stability study at 40±2ºC/ 75±5% RH.Keywords

Osmotic drug delivery system (ODDS) provides the drug dose and dosing interval in optimized manner to maintain drug concentration within therapeutic window thus ensuring efficacy and minimizing toxic effects. The objective of ODDS is to release pharmacologically active ingredients in a predetermined, predictable and reproducible manner to systemic circulation. ODDS delivers a drug to large extent is independent of the physiological factors of the gastrointestinal tract, pH. Hence it can be utilized for systemic as well as targeted delivery of drugs. The release of drugs from osmotic system controls the drug release by controlling various formulation factors such as solubility, osmotic pressure of the core components, size of the delivery orifice and nature of the rate controlling membrane. The design of osmotic system is achieved by optimizing formulation and processing factors to deliver drugs in preprogrammed rate and controlled manner. In present study is an update on osmosis, different types of osmotic systems, components of ODDS, key parameter sand some patents.Keywords

The current research involves the development of controlled porosity osmotic pump (CPOP) tablets of ritonavir for the treatment of HIV infection. Core tablets were prepared by wet granulation method using hydroxyl propyl methyl cellulose (HPMCE5LV) polymer, mannitol as osmogen, MCC as diluents and other additives. The CPOP tablets were coated with cellulose acetate as wall forming material, poly ethylene glycol as flux regulating agent, and sorbitol acts as pore forming material in SPM. The prepared tablets were evaluated for FTIR, DSC, precompression parameters, post compression parameters, in vitro drug release study and scanning electron microscopy study. The optimized formulation RM5 showed 94.83% at the end of 14 hrs with zero order drug release. The difference factor (f1) and similarity factor (f2) for RM5 were observed 14.61 and 75.12 respectively. Optimized formulation did not show any significant change on the pH and agitation intensity, but it depends on osmotic pressure of dissolution media indicated that mechanism of drug release was due to osmotic pressure. SEM micrographs confirmed that no pores were found before dissolution and after dissolution had shown the porous nature of the membrane. Short term stability study at 40 ± 2 °C/75 ± 5% RH for three months on the RM5 formulation indicated that there was no significant change weight variation, %friability, drug content and in vitro drug release.Keywords

The aim of the current study was to develop immediate release tablets (IRT) of topiramate using different concentrations of sodium starch glycolate (SSG) as super disintegrant. Four different formulations of IRT were prepared using wet granulation method. Different pre compression and post compression characterization of tablet was carried out. In vitro drug release studies were carried out in USP II paddle type dissolution apparatus for different formulation and the batch containing 7.5 mg of SSG per tablet gave maximum amount of drug release of 90.76% at the end of 50 mins. Drug and excipients compatibility studies were carried out through FTIR spectroscopy. FTIR spectroscopy studies revelled that there is no interaction between drug and different excipients used in formulation. Short term stability studies (at 40±2ºC/75±5% RH) on the best formulation indicated that there were no significant changes in release profile and drug content after a period of one to three month. Among all the formulations, F4 formulation was finally optimized.Keywords
