Abstract
Tablet is the most preferred oral dosage form, due to many advantages it offers to formulators as well as physicians and patients. However, the process of manufacturing tablets is complex. Hence, careful consideration has to be given to select right process, and right excipients to ultimately give a robust, high productivity and regulatory compliant product of good quality.

ABSTRACT
Solubility, the phenomenon of dissolution of solute in solvent to give a homogenous system, is one of the important parameters to achieve desired concentration of drug in systemic circulation for desired pharmacological response. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development. The insufficient dissolution rate of the drug is the limiting factor in the oral bioavailability of poorly water soluble compounds. This review discusses BCS classification, carriers for solubility enhancement and different techniques for solubility enhancement.Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include micronization, nanonization, sonocrystallization, supercritical fluid method, spray freezing into liquid and lyophilization, evaporative precipitation into aqueous solution, use of surfactant, use of co-solvent, hydrotropy method, use of salt forms, solvent deposition, solubilizing agents, modification of the crystal habit, co-crystallisation, complexation and drug dispersion in carriers.Selection of solubility improving method depends on drug property, site of absorption, and required dosage form characteristics.With the advent of combinatorial chemistry and a high throughput screening, the number of poorly water soluble compounds has increased solubility. A success of formulation depends on how efficiently it makes the drug available at the site of action.The purpose of this review article is to describe the techniques of solubilization for the attainment of effective absorption with improved bioavailability.

ABSTRACT
This paper describe a simple, precise and economical spectrophotometric method for the quantitative determination of Deflazacort(DFCT) in tablet dosage form. Method is based on the estimation of DFCT in aqueous acetonitrileat 246 nm. Beer’s law was obeyed in the concentration range of 4-14 µg/ml. The accuracy of the method was assessed by recovery studies and was found to be 99.38±0.15 for DFCT. Results of the analysis were validated statistically so that it can be used for routine analysis of DFCT in tablet dosage form.

ABSTRACT
A method for simultaneous estimation of Atorvastatin (ATVS) and Amlodipine (AMLD) in raw material and in combined tablet dosage form has been developed. The method employs the application of RP-HPLC. Chromatgraphy was carried out on a nucleosil C-18,250 x 4.6 mm column using a mixture of phosphate buffer and methanol  (50:50 v/v)  as the mobile phase at a flow rate of 1.3 ml/min.  Run time was 15 min.  Detection was done at 245 nm and retention time of ATVS was 6.97 min and 3.96 min of AMLD.³  This method produced linear responses in the concentration range 20-140 µg/ml and 10-70 µg/ml for ATVS and AMLD respectively. The accuracy of the method was assessed by recovery studies and was found to be 100.54± 0.19 and 100.08±0.80 for ATVS and AMLD respectively.The procedure was successfully applied for the simultaneous determination of both drugs in laboratory prepared mixture of raw material and in market available tablet dosage form. Results of the analysis were validated statistically so that it can be used for routine analysis of ATVS and AMLD in combined tablet dosage form.^4-6
