A simple, precise and rapid RP-HPLC method was developed for the determination of doxazosin mesylate in pharmaceutical formulations. The method was carried out on a Chromolith RP-C18 column using a mixture of potassium phosphate buffer and methanol (40:60 v/v) and detection was done at 251 nm. The linearity range was 1-5 μg/ml. The retention time of the drug was 3.8 min. The LOD and LOQ were found to be 0.1 μg/ml and 0.5 μg/ml, respectively.
Background: There is an increase in the prevalence of hypertension all over the world, including India. Hypertension can be initially managed with non-pharmacological measures. This study aims to assess the knowledge of non-pharmacological measures to control hypertension and its application in a geriatric hypertensive population. Methods: The study was conducted at the Department of Physiology, SVU, Vadodara, India. A total 110 hypertensive patients were included in the study and a non-validated survey was conducted to examine knowledge of non-pharmacological measures to control hypertension in this group of patients. Frequencies, percentages, means and standard deviations were calculated and reported. Results: Only 10% of the respondents knew the normal values for blood pressure. Approximately 38% of the subjects did not measure their blood pressure regularly. A total of 24% subjects knew that body weight has a correlation with hypertension. About 27% said that there was no correlation between salt intake and hypertension, and 88% of the study population did not carry out any form of physical activity. Conclusion: Hypertension can be controlled by life style modifications such as exercise, weight management and a healthy diet. Public health and education measures targeting hypertensive population need to be taken to decrease the risk factors for cardiovascular diseases and, therefore, improve people's health and quality of life.
Background: Increased prevalence of hypertension in all over the world is well recognized. Hypertension affects almost all body organs and systems. It can be managed by using nonpharmacological measures as well. Objective: To assess knowledge of non-pharmacological measures to control of hypertension and its application in geriatric hypertensive population. Methods: The study was conducted in the
The aim of the investigation was to develop and validate a reversed-phase high pressure liquid chromatography (RP-HPLC) method for the simultaneous estimation of etodolac (ETD) and 5-FU in bulk and coated tablet dosage form. The method was validated in terms of linearity, precision, accuracy, and specificity, LOD, and LOQ according to ICH guidelines. The standard instrument parameters were optimized using C18 reverse phase Inertsil® ODS (250 × 4.6 mm, 5µ particle size) column with system equipped with photodiode array (PDA) detector. An optimized ratio of mobile phase in RP-HPLC under low pressure gradient mode comprising of 60:40 % v/v of acetonitrile and di-potassium hydrogen phosphate buffer (pH 6.4; 25 mM), provided sharp peaks (having adequate molar absorptivity at λmax of 280 nm) with short retention time of 4.3+/-0.2 and 11.5+/-0.3 min for 5-FU and etodolac, respectively. Results indicated the method was linear, precise, accurate, rugged and robust with RSD values <2%. The percentage recoveries of both the drugs were within the limits of 90-110% at various spiked concentrations. The proposed method was found to be highly effective and could be successfully employed for the quantification of 5-FU and ETD in bulk drug and tablet formulations for routine analysis.
