The aim of this review is to present the status of the BCS and discuss its future application in pharmaceutical product development. The proper understanding of the complex polyphasic systemhydrates–polymorphs–amorphous state needs several analytical methods. 3- Protection from gastric juice. Honmane, et al. H. Brittain, Physical Characterization of Pharmaceutical Solids, Marcel Dekker, Inc., 1995. For liquid It is essential to test the in vivo behavior of the new drug for successful formulation of a dosage from good bioavailability. This minireview summarizes some of the parameters and approaches that can be used to evaluate compounds in the early stages of drug discovery. This the issued observation of melting under a microscope equipped with a heated and lagged sample stage. The drug development bottlenecks of attrition and development time are being addressed by acquiring a profile of the candidate's physicochemical and physiological properties during early discovery phases. Some investigation of polymorphism and crystal habit of a drug substance as it relates to pharmaceutical processing is desirable during its Preformulation evaluation especially when the active ingredient is expected to constitute the bulk of the tablet mass. Preparation and Characterization of Liquisolid Compacts for Improved Dissolution of Telmisartan, Effect of Crystal Habit on Intrinsic Dissolution Behavior of Celecoxib Due to Differential Wettability, Impact of Crystal Habit on Biopharmaceutical Performance of Celecoxib, Impact of preformulation on drug development, Pharmaceutical Solids: A Strategic Approach to Regulatory Considerations, A Theoretical Basis for a Biopharmaceutic Drug Classification: The Correlation of In Vitro Drug Product Dissolution and In Vivo Bioavailability. These include microscopy (including hot stage microcopy), infrared spectrophotometry, single-crystal x-ray and x-ray power diffraction, thermal analysis, and dilalometry. Differential thermal analysis (DTA) measures the temperature difference between the sample and a reference as a function of temperature or time when heating at a constant rate differential scanning calorinetry (DSC) is similar to DTA except that the instrument measures the amount of energy required to keep the sample at the same temperature as the reference i.e. The characterization of amorphous solids reveals their structures, thermodynamic properties, and changes (crystallization and structural relaxation) in single- and multi-component systems. Over recent years, drug release/dissolution from solid pharmaceutical dosage forms has been the subject of intense and profitable scientific developments. Compared to CEL-A, CEL-P exhibited significantly faster dissolution kinetics in aqueous media and significantly higher Cmax and shorter Tmax in an oral bioavailability study. The physical, mechanical, and chemical properties of excipients affect various formulation parameters, such as disintegration, dissolution, and shelf lif … Excipient Stability in Oral Solid Dosage Forms: A Review AAPS PharmSciTech. Expert opinion: It was calculated that even for partially amorphous materials the apparent solubility enhancement (theoretical or measured) is likely to influence in-vitro and in-vivo dissolution behavior. Contamination by the alpha-polymorph (down to a level of 1.4% w/w of the formulation) could be detected. Physicochemical and biopharmaceutical characterization of NCEs is a decisive parameter during product development. Taste masking: Chloramphenicol is very bitter in taste so it is very difficult to make a paediatric liquid dosage form with chloramphenicol base. It is hoped that this review will lead to a more direct approach to the characterization of pharmaceutical solids and ultimately to faster approval of regulatory documents containing information on pharmaceutical solids. The salt form must fulfil the needs of the targeted formulation, In most of the cases the theoretical concept does not exist and some empirical equations have proved to be more appropriate.
