Aim: The aim of the study is to assess effect of lifestyle modifications and implementation of DASH diet in daily life on blood pressure in hypertensive patients. Method: A prospective observational study was conducted for a period of six months from Dec- 2013 to May-2014. The data was collected by self prepared form and analyzed using descriptive statistics. Counselling on lifestyle changes and implementation of The DASH diet were given to the study population and post counseling changes were collected at visit 2. The significant difference in systolic and diastolic blood pressure was calculated by unpaired t-test. Results: A total of 186 patients were enrolled in the study, the mean (SD) age was 55.89(9.44), the percentage distribution of the study population showed that 103(55.37%) females and males 83(44.62%). The current study showed that overall effect of life style changes and implementation of the DASH diet in their daily life had a significant decrease in systolic (p<0.0001) and diastolic blood (P<0.0001) pressure of the study population. There was significant difference...

A simple, precise, and robust spectrophotometric method for the determination of Ceftriaxone sodium has been investigated and validated. The proposed chemical reaction involved involves the reaction primary amine of Ceftriaxone sodium with nitrite solution in acidic medium to form a diazotized product followed by the reaction of the diazotized product with suitable coupling reagent to obtained a colored product. Ceftriaxone sodium has shown λmax 510nm with absorbance of 0.126. The method obeys Beer Lambert law at concentration range of 1-20ppm by showing linearity curve between absorbance and concentration. In the method detection limits was observed 0.726ppm with quantification limit of 2.42ppm and standard deviation of 0.242. In the present work an attempt was made to develop a simple, less expensive and more reliable method for the determination of Ceftriaxone sodium in pure and pharmaceutical...

The objective of present study was to develop effervescent tablets of promethazine (PMZ) for the treatment of emesis. Effervescent tablets were prepared by direct compression method and were optimized using 32 full factorial design. Amount to sodium starch glycolate(X1) and amount of sodium bicarbonate (X2) were selected as independent variables, whereas disintegration time (Y1), amount of carbon dioxide (Y2) and drug release in 5 minutes (Y3) were selected as dependent variables. All the batches were also evaluated for general post compression evaluation of tablet such as- weight variation, thickness, friability and hardness. From the results of design batches, best batch was selected and evaluated for in vivo pharmacokinetic study in a rabbit model. The disintegration time ranged from 58.67±0.27sec to 228.67± 0.67sec while amount of carbon dioxide ranged from 0.1±0.082 gm to 0.29±0.061gm in all the design batches. From the results of design batches, batch F9 was selected as optimized batch due to higher amount of carbon dioxide released and faster drug release as compared to other batches. Batch...

Neuropathic pain is a persistent chronic pain caused by primary lesion or dysfunction of neurons which is primarily characterized by hyperalgesia, allodynia. There is some evidence that acamprosate might inhibit Ca2 influx through NMDA and voltage-dependent Ca2 channels. λ-carrageenan (0.1 ml of 1% w/v) into i.pl. region of the hind paw was injected to produce acute inflammation. Unilateral peripheral mononeuropathy was induced by sciatic nerve ligation. Thermal and mechanical hyperalgesia and cold allodynia were assessed. The extent of oxido-nitrosative stress was assessed by estimating the levels of thiobarbituric acid reactive substances, catalase and superoxide dismutase activity and nitrite levels in both sciatic nerve and dorso-lumbar spinal cord homogenate in CCI model. The one hour pre-treatment with acamprosate (100 and 200 mg/kg, p.o) was given. Then second dose acamprosate treatment at the 19 hr post-carrageenan given after first dose oral administration of acamprosate at a dose of 200 mg/kg., but not 100 mg/kg significantly reversed the established mechanical hyperalgesia without producing significant effect on thermal hyperalgesia. The two week repeated...

Dexmedetomidine, approved by the Food and Drug Administration (FDA) in 1999 as a sedative for use in the intensive care unit, is a potent and highly selective α2-adrenoceptor agonist with significant sedative, analgesic and anxiolytic effects mostly used in the intensive care units. This article describes validation for determination of related substances of dexmedetomidine (impurity-1) in dexmedetomidine hydrochloride injection by using a high performance liquid chromatography. The high performance liquid chromatography resolution was achieved on an Phenomenex Luna C18 (2) 150 x 4.6 mm, column with an isocratic elution at a flow rate of 1.0 mL/min using a mobile phase of75-25% of Buffer with Acetonitrile. The detection was performed by a photo diode array Detector. The method was validated in the concentration range of 0.003 ppm (Limit of quantification) to 0.06 ppm (150%). The intra and inter-day precision and accuracy were within Limit (10 % RSD). The overall mean recoveries of Dexmedetomidine were 97.5% for Limit of Quantitation and 95.6 % for 50% to...
