Uric acid is the end-product of purine metabolism and a major antioxidant in humans. Most of the uric acid produced from the catabolism is readsorbed into the blood circulation system after primary filtration and partial secretion by the kidney. Uric acid levels in physiological fluids such as plasma and urine serve as valuable indicators for certain clinical conditions. An elevated uric acid in u...
A rapid reverse phase high performance liquid chromatographic method was developed for the estimation of Manidipine dihydrochloride in its pure form as well as in tablet dosage forms. Chromatography was carried out on an phenomenex C18 column (250´4.6mm, 5 µm), using a mixture of acetonitrile and water (80: 20 v/v) with pH adjusted to 3.5 with ortho phosphoric acid (0.1 % v/v) as the mobile ph...
One of the biggest challenges faced by pharmaceutical scientists is poor solubility and bioavailability of new chemical entities (NCEs). According to BCS classification; approximately 25% of all compounds are classified as highly soluble and permeable. Nearly 40% of the new chemical entities currently being discovered are lipophilic so poorly water soluble drugs. BCS Class II and Class IV have low...
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women. PCOS varies from a mild menstrual disorder to severe disturbance of reproductive and metabolic functions. Statins, 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitors with intrinsic antioxidant properties, exert profound and broad-reaching effects on various types of tissues. By blocking an early step of th...
ANTI-HYPERGLYCEMIC ACTIVITY OF SIMVASTATIN ALONE (THERAPEUTIC DOSE) AND COMBINATION OF SIMVASTATIN AND GLIPIZIDE (SUB THERAPEUTIC DOSES) ON ALLOXAN INDUCED HYPERGLYCEMIA IN ALBINO RATS
The present study was designed to evaluate anti-hyperglycemic activity of simvastatin alone and the combination of sub therapeutic doses of simvastatin and glipizide. Hyperglycemia was induced experimentally in albino rats by subcutaneous injection of alloxan in a dose of 175 mg/kg body weight. After 72 hours of alloxan treatment, rats showing hyperglycemia (blood glucose level of 400 mg/dl and ab...
FORMULATION OF RANITIDINE HYDROCHLORIDE GASTRO RETENTIVE FLOATING TABLET BY USING DIFFERENT RATIO OF POLYMERS
The aim of the present investigation was to develop a novel gastro retentive dosage form of Ranitidine hydrochloride (RHCl) to achieve prolong gastric retention, increase drug bioavailability and to modulate the release of RHCl in the stomach, by using various ratios of HPMC E-15, a low-density grade polymer and it was cheaper and easily available along with Carbopol 934, as gel former. Sodium bic...
Cardiospermum halicacabum L. var. microcarpum (Kunth) Blume and var. luridum (Blume) Adelb. (Sapindaceae) are used for various ailments in Indian traditional medicines. The present study evaluated the antiulcerogenic property of seed oils (Petroleum ether extracts) in animal model. Ethanol induced gastric ulcers was used for this study and analysed for gastric volume, ulcer score pH, free and tota...
Methanolic extracts of leaf, bark, stem and root of D. paniculata were screened for phytochemicals and antibacterial activity against ten different pathogens. Various phytochemicals such as terpenoids, flavonoids, coumarins, saponins and tannins were found to be present. Leaf and bark extract exhibited maximum antibacterial activity against S. aureus, P. vulgaris and E. coli with MIC value of 2.5 ...
Mycobacterium tuberculosis is a deadly infectious disease, there is rising death of humans every year because of this disease, availability of genome sequences of Mycobacterium tuberculosis has provided tremendous amount of information that can be useful in drug target and new vaccine development. Sequence similarity provides accurate annotation for genes in newly sequenced genomes. In this pres...
SPECTROFLUORIMETRIC DETERMINATION OF SOME H1 RECEPTOR ANTAGONIST DRUGS IN PHARMACEUTICAL FORMULATIONS AND BIOLOGICAL FLUIDS
A validated simple, economic, selective, and stability indicating spectrofluorimetric method was developed for the determination of some antihistaminic H1 receptor antagonist drugs namely ebastine (EBS), cetirizine dihydrochloride (CTZ), and fexofenadine hydrochloride (FXD). The method is based on the reaction of the cited drugs with 2-cyanoacetamide in alkaline medium to give highly fluoresce...
