    ABSTRACT
    A novel stability-indicating RP-HPLC method has been develop and validated for quantitative analysis of Sitagliptin in the bulk drug and in its pharmaceutical dosage forms using Hypersil–BDS- C18 column (250x4.6mmi.d, 5µ particle size) with 10mM Phosphate buffer (PH-3.5): ACN 60:40%v/v as isocratic mobile phase enabled separation of the drug from its degradation products. UV detection was performed at 260 nm. The method was validated for linearity, accuracy (recovery), precision, sensitivity, ruggedness and robustness. The linearity of the method was excellent over the range 10–60μg/ml (correlation coefficient 0.999). The limits of detection and quantification were 0.21 and 0.640μg/ml, respectively. Recovery of Sitagliptinfrom the pharmaceutical dosage form ranged from 99.99 to 100.05%.

    Sitagliptin was subjected to stress conditions (Hydrolysis (acid, base), oxidation,thermal and photo degradation) and the stressed samples were analysed by use of the method. Degradation was observed in acid, base, and 30% H2O2. The drug was stable under the other stress conditions investigated. The degradation products were well resolved from main peak. The forced degradation studies prove the stability indicating power of the method.

    Abstract:
    Novel drug delivery systems have several advantages over conventional multi dose therapy. Recent trends indicate that microparticulate drug delivery systems are especially suitable for achieving controlled or delayed release oral formulations with low risk of dose dumping, flexibility of blending to attain different release patterns as well as reproducible and short gastric residence time. The release of drug from microparticles depends on a variety of factors including the carrier used to form the microparticles and the amount of drug contained in them. Consequently, microparticulate drug delivery systems provide tremendous opportunities for designing new controlled and delayed release oral formulations, thus extending the frontier of future pharmaceutical development. One such approach is using microspheres as carriers for drugs. Microencapsulation is a process where by small discrete solid particles or small liquid droplets are surrounded and enclosed by an intact shell. Microencapsulation is used to modify and delayed drug release form pharmaceutical dosage forms. A well designed controlled drug delivery system can overcome some of the problems of conventional therapy and enhance the therapeutic efficacy of a particular drug. It is the reliable means to deliver the drug to the target site with specificity, if modified, and to maintain the desired concentration at the site of interest without untoward effects. Microspheres received much attention not only for prolonged release, but also for targeting of anticancer drugs to the tumor. The intent of the paper is to highlight the potential of microencapsulation technique as a vital technique in novel drug delivery.

    ABSTRACT
    Alfuzosin is a non-subtype specific alpha(1)-adrenergic blocking agent that exhibits selectivity for alpha(1)-adrenergic receptors in the lower urinary tract. Inhibition of these adrenoreceptors leads to the relaxation of smooth muscle in the bladder neck and prostate, resulting in the improvement in urine flow and a reduction in symptoms in benign prostate hyperplasia. Alfuzosin also inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation. The alfuzosin of the present investigation is designed to retain in the stomach and deliver the drug alfuzosin for longer periods of time. The developed floating provides increased absorption of the alfuzosin at a rate such that effective plasma levels can be achieved and maintained for a prolonged duration. Formulations 6 displayed drug release considered in 0.1N HCL and Formulation 6 shows better drug release in dissolution profile.

    ABSTRACT
    Solving solubility problems is a major challenge for the pharmaceutical industry with developments of new pharmaceutical products, since nearly half of the active substances being identified are either insoluble or poorly soluble in water soluble. Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include Liquisolid technique, 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.The “Liquisolid” technique is a novel and capable addition towards such an aims for solubility enhancement and dissolution improvement, thereby it increases the bioavailability.Liquisolid technique is based upon the admixture of drug loaded solutions with appropriate carrier and coating materials. The use of non-volatile solvent causes improved wettability and ensures molecular dispersion of drug in the formulation and leads to enhance solubility. By using hydrophobic carriers (non-volatile solvents) one can sustained the release of drugs by this technique. Liquisolid compacts demonstrated a considerably higher drug dissolution rates than those of conventionally made capsules and directly compressed tablets. This was due to the increased wetting properties and surface of drug available for dissolution. By using this technique, solubility and dissolution rate of water insoluble drugs can be improved. This review paper highlights the advantages, disadvantages, mechanism of enhanced drug release, classification, evaluation and application of liquisolid technique to enhance the solubility and dissolution of water insoluble drugs.
