Dexibuprofen: Statistical assessment of drug release kinetics and investigative quality perspective

Healthcare professionals including physicians and pharmacists have been trying since long to come across and work out regarding the issue of generic alternatives, which is highly affected by factors like therapeutic efficacy, cost effectiveness, aesthetic and elegant appearance and implementation of packaging number over the drug product. However, the community pharmacist professionals are also facing difficulty in making decision regarding selection and dispensing the most efficacious brand to the patients. In this regard, the initiation of recent approaches for the development of amenable drug products has led to evolve the concept of generating new avenues for achieving higher patient compliance. Hence, the objective of this study was to evaluate the quality attributes and make comparisons regarding different brands of Dexibuprofen available in market of Karachi, Pakistan. The study is based on evaluation of physical chemical parameters of five different brands. Moreover, a comparative dissolution profile of selected brands of Dexibuprofen was also performed by applying numerous approaches. DEX-1was selected as reference while DEX-2-DEX-5was selected as test brands. Results of all the selected brands met all the compendial requirements. Interpretation of the entire aforementioned test was evaluated using model independent, model- dependent and one - way ANOVA. The work presented in this study has been designed to provide quality standard products easily accessible in Pakistani market

Assessment of predictor variables and clinical consequences associated with surgical site infection in tertiary care setting, Karachi, Pakistan

Among the well-known Health care-associated infections [HAIs], surgical site infections [SSIs] contribute to considerable high mortality and morbidity rate, substantial prolongation in hospitalization period and extra expenses in terms of treatment cost. This study was aimed to evaluate the predictive variables associated with surgical site infections, and their clinical consequences. This was a prospective, cross sectional study conducted in the surgical department of tertiary care setting in Karachi, Pakistan. Each patient was followed up from the time of admission until time of the discharge postoperatively for 30 days. A total of 554 surgical procedures were performed and 81 SSIs were identified. The predictor variable/risk factors significantly associated with the presence of SSI were age, gender, BMI, ASA score, co-morbid condition, surgical wound class, emergency surgeries, duration of surgery, type of anesthesia, prosthetic implant, pre operative length of stay and pre operative blood transfusion. Outcomes of such studies may be utilized in the design of a multi factorial practice to get better patient's safety and clinical outcomes

Spectrophotometric method development and validation for determination of chlorpheniramine maleate in bulk and controlled release tablets

Spectrophotometric technique is considered to be the simplest and operator friendly among other available analytical methods for pharmaceutical analysis. The objective of the study was to develop a precise, accurate and rapid UV-spectrophotometric method for the estimation of chlorpheniramine maleate [CPM] in pure and solid pharmaceutical formulation. Drug absorption was measured in various solvent systems including 0.1N HCl [pH 1.2], acetate buffer [pH 4.5], phosphate buffer [pH 6.8] and distil water [pH 7.0]. Method validation was performed as per official guidelines of ICH, 2005. High drug absorption was observed in 0.1N HCl medium with lambdamax of 261nm. The drug showed the good linearity from 20 to 60microg/mL solution concentration with the correlation coefficient linear regression equation Y= 0.1853 X + 0.1098 presenting R2 value of 0.9998. The method accuracy was evaluated by the percent drug recovery, presents more than 99% drug recovery at three different levels assessed. The % RSD value

Incidence of drug interactions in intensive care units in tertiary care settings: Classification, facts and measures

Drug-drug interactions [DDIs] are extremely significant concern, particularly in sensitive population including pediatric and geriatric. Propensity for the development of DDIs is high in patients admitted at intensive care units [ICU]. This study was conducted to evaluate the DDIs incidence, facts and measures in ICU. From a total of 150 cases studied for ICU patients, with the mean age of 56.37+/-12.45 years, 55.33% were male and the rest were female 44.66%. The demographic information like age, gender and main diagnosis details of study participants that were extracted from the patients' clinical record. A statistically significant association between the drug interaction and the number of drugs prescribed per prescription was observed [p <0.0001]. Concerning the onset of outcome, 52% of DDIs distinguished as delayed onset of effect [past 24 hours] and 35% were categorized as rapid onset [within 24 hours]. Despite the facts regarding patient safety and minimizing DIs error, polypharmacy is still frequent in critically ill patients admitted in ICU attributed high risk of adverse reactions due to use of multiple interventions to treat severity of disease condition. Such studies may be used to develop an effective tool for the diagnosis and management of DDIs
