ABSTRACT
* A simple, specific, accurate and stability-indicating reversed phase high performance liquid chromatographic method was developed for simultaneous estimation of Tadalafil and Dapoxetine HCL, Water Symmetry C-18 (150 x 4.6 mm),5 µ and a mobile phase composed of Buffer : Acetonitrile (65:35)

* The retention time of Tadalafil and Dapoxetine HCL were found to be10.08 and 4.45 min respectively. Linearity was established for Tadalafil and Dapoxetine HCL in the range of 8.0-60 μg/ml and 24.0-180.0 μg/ml respectively. The percentage recovery of Tadalafil and Dapoxetine HCL were found to be in the range of 99.7-100.6% and 98.07-99.09% respectively. The drug was subjected to acid and alkali hydrolysis, oxidation, dry heat and photolytic degradation. The degradation studies indicated, Tadalafil showed degradation in acid and alkali while it was found stable in H₂O_2, photolytic and in presence of dry heat and Dapoxetine showed degradation in thermal and peroxide while it was found stable in rest of parameters . The degradation products of Tadalafil and Dapoxetine HCL in acidic, alkaline conditions were well resolved from the pure drug with significant differences in their retention time values. This method can be successfully employed for the quantitative analysis of Tadalafil and Dapoxetine HCL in bulk drugs and formulations.

ABSTRACT
Medicinal chemistry involves chemical aspects of identification, and then systematic, thorough synthetic alteration of new chemical entities to make them suitable for therapeutic use. Indazoles have an important role in medicinal chemistry. Indazole  nucleus is an important class of nitrogen containing heterocyclic widely used as key building block for the synthesis of various pharmaceutically important agents. Indazole possess wide range of biological activities such as bactericidal, fungicidal, analgesic, antihypertensive, anti-inflammatory and antitumor. In the present study we have synthesized some novel 3,3a,4,5-tetrahydro-2-(substituted benzenesulphonyl)-3-(substituted phenyl)-2H-benzo[g]indazoles, by condensation of  1-tetralone with different substituted aromatic aldehydes and the resulted 2-(substituted benzylidene)-3,4,-dihydronaphtalen-1-ones on reaction with hydrazine hydrate in methanol followed by treatment with different substituted sulfonyl chlorides in pyridine gave the titled compounds.The synthesized compounds were characterized by IR, NMR and Mass spectral analysis. All newly synthesized derivatives were evaluated for antibacterial activity against  gram + ve and gram-ve bacteria B.cereus, S.aureus and E.coli respectivelyand antifungal activity againstC.albicans and all the synthesized compounds showed significant antibacterial and antifungal activity.

ABSTRACT
Venous thromboembolism (VTE) complicates approximately 1 to 2 of 1,000 pregnancies, with pulmonary embolism (PE) being a leading cause of maternal mortality and deep vein thrombosis (DVT) an important cause of maternal morbidity. The main reason for the increased risk of thromboembolism in pregnancy is hypercoagulability, which has likely evolved to protect women from the bleeding challenges of miscarriage and childbirth. Women are at a 4- to 5-fold increased risk of thromboembolism during pregnancy and the postpartum period compared with when they are not pregnant. Eighty percent of the thromboembolic events in pregnancy are venous, with an incidence of 0.61 to 1.72 per 1000 pregnancies.Includes a history of thrombosis, inherited and acquired thrombophilia, maternal age greater than 35, certain medical conditions, and various complications of pregnancy and childbirth.

Despite the increased risk of VTE during pregnancy and the postpartum period, most women do not require anticoagulation. The intensity of the anticoagulation will depend on the indication and the monitoring will depend on the intensity. At the time of delivery, anticoagulation should be manipulated to reduce the risk of bleeding complications while minimizing the risk of thrombosis. There are no large trials of anticoagulants in pregnancy, and recommendations are based on case series, extrapolations from nonpregnant patients and the opinion of experts. Nonetheless, anticoagulants are believed to improve the outcome of pregnancy for women who have, or have had, VTE.
