The objective of the present study was to develop venlafaxine hydrochloride orodispersible tablet by using conventional techniques which are simple and cost effective such as use of superdisintegrant technology. In this, sodium starch glycolate and Crosscarmellose sodium crosspovidone and kyron-T-314 were used in the rapid disintegration of the tablets. In this various trials were conducted for the selection of optimum concentration of superdisintegrant. The optimized formula aids in the stabilization of final product. The blend and compressed tablets were evaluated for physical characteristics like bulk density, tapped density, angle of repose, hardness, friability, disintegration time, wetting time, water absorption ratio, In-vitro dispersion time and chemical characteristics like In-vitro dissolution, content uniformity and assay. The stability study was conducted for the optimized batch. This design of dosage form will open a new era for rapid disintegration tablets....

Introduction: This randomized double blind study was started with an objective of comparing two commonly used vasopressors – ephedrine and phenylephrine in infusion form with crystalloid co-hydration to reduce spinal anesthesia induced hypotension in elective caesarean section. Methods: One hundred patients were randomized into two groups to receive either 100 μg/ml phenylephrine (group-P, n=50) or 5mg/ml ephedrine (group-E, n=50). Immediately after spinal injection the study solution was started prophylactically in every patient at the rate of 60ml/hr. A predefined algorithm was used to adjust the infusion rate according to the systolic blood pressure (SBP). Results: Mean vasopressor required was significantly more in group-P than group-E (p<0.001). Incidence of hypotension were more in group-E than group P. Minimum systolic B.P and time to minimum systolic B.P. was lower in group-E compared to group-P (P value <0.001). Incidence of bradycardia was higher in group P and Incidence of nausea and vomiting was significantly higher in ephedrine group. Umbilical arterial pH and Umbilical Venous pH was lower in group-E and the difference was highly...

Human body is a perfect natural habitat for numerous microorganisms like bacteria, fungi, yeasts and some viruses which are termed as microflora of a body. Amongst its upper respiratory tract, is the most common infections in the world. Our study aimed at determining the antimicrobial resistance of bacterial strains against several antibiotics, isolated from the respiratory tract of the suspected patients. The study was confirmed using in vitro antimicrobial disk diffusion method. Total of 30 samples were studied. 20 bacterial strains were isolated of which 15 were Gram positive bacteria, including Staphylococcus aureus (7 strains), Staphylococcus epidermidis (4 strains) and Corynebacterium diphtheria (4 strains) whereas 5 strains of Gram negative bacteria, includes Neisseria meningitidis. The resistance determined by the antibiotics used as, amoxicillin, Staphylococcus aureus (87.71%), Staphylococcus epidermis (85.71%), Corynebacterium diphtheria (75%), erythromycin, Staphylococcus epidermidis (100%), Corynebacterium diphtheria (100%), Neisseria meningitidis (60%), Staphylococcus aureus (57.14%); tetracyclin, Staphylococcus epidermidis (50%), Corynebacterium diphtheria (50%), Neisseria meningitidis (40%), Staphylococcus aureus (29%); ciprofloxacin, Neisseria meningitidis (80%), Staphylococcus aureus (29%); penicillin showed 100 %...

High Blood pressure or hypertension is one of the most ubiquitous yet nettle some medical problems that physician and health care provider face in the office. In present study amlodipine and cilnidipine have been selected to evaluate and compare their efficacy and tolerability in mild to moderate essential hypertension. 60 patients of uncomplicated mild to moderate essential hypertension were evaluated for clinical efficacy, effect on biochemical parameters and side effects in 6 weeks of treatment. They were divided into 2 groups of 30 patients each, making a total of 60 patients. First group of 30 patients was given cilnidipine 5-20 mg/day and second group of 30 patients was given amlodipine in dose of 5-10 mg/day and dose was adjusted according to control of blood pressure. In the present study, it was clearly evident that cilnidipine and amlodipine both are effective antihypertensive drugs. Both the drugs were instrumental in decreasing systolic blood pressure significantly (p<0.05).. Both the drugs also decreased the diastolic blood pressure significantly (p<0.05). There was no significant...

Three N,N’-diacyl-2,6-diaminopyridines were synthesized with a saturated undecanoic acid or an unsaturated undecenoic acid in order to study the effect of the alkyl-chain on the nano architectures. The imaging studies showed that the compound possessing two unsaturated alkyl chains exhibited a tubular structure. On the other hand compound possessing two saturated alkyl chain showed poorly formed nanotubes and the compound with one saturated and one unsaturated alkyl chain formed nanosheets. These results indicate that the morphology is strongly dependent on the alkyl...
