ABSTRACT:
A simple, precise and accurate difference spectroscopic method has been developed for the estimation of Ciprofloxacin Hydrochloride in bulk drug form by difference spectrophotometric method. Ciprofloxacin Hydrochloride has exhibited maximum absorbance at about 272nm and 278nm in acidic and basic solution respectively. Beer’s law was obeyed in the concentration range of 2-10 µg/ml in both the cases. The regression of coefficient was found to be r²=0.9982. The LOD and LOQ value were found to be 0.5140ppm and 0.5577ppm respectively. The proposed method was successfully applied for the determination of Ciprofloxacin Hydrochloride in bulk drug. As per ICH guidelines the result of the analysis were validated statistically and were found to be satisfactory.

ABSTRACT
Introduction: Diabetes mellitus is on alarming rise in India. Drug utilization studies help to identify the adherence to standard guidelines and extent of drug use and to evaluate the rational drug usage.
Aims and objectives: To determine the drug utilization pattern and effectiveness of oral hypoglycemic agents among diabetes mellitus patients.
Materials and methods: It is a prospective observational study carried out for a period of six months at RIMS kadapa, and two others diabetic centers. The diabetic patients who visited the medicine outpatient department were included. After obtaining approval from institutional ethical committee, a structured data collection form was used to collect demographic data, complete prescription details and other relevant information required for the study. The drug utilization pattern was determined. The drugs were categorized by Anatomical therapeutic classification (ATC) and DDD/1000 inhabitants/day was calculated by using WHO guidelines. Among all oral hypoglycemic agents the most effective drug/combination in this region was identified.
RESULTS:  716 prescriptions were assessed out of which,401(56.0%) were females and 315(43.9%) were males, most of the patients were in the age group of 40-60 for males 175(55%) and females 205(51.1%). Hypertension was the most common co-morbid seen. The average number of drugs per prescription was 4.26 and anti-diabetics per prescription was 1.79. DDD/1000 inhabitants/day for metformin (A10BA02) was 10.5, glimiperide (A10BB12) was 9.3, glibenclamide (A10BB01) was 7.91, pioglitazone (A10BG03) was 7.25. Out of 716 patients 311(45.25%) patients were on Monotherapy, and 405 (56.5%) were on Combination therapy.A total of 200 newly diagnosed patients of diabetes mellitus were enrolled in the study out of which only 128 members were followed up successfully. The combinations of Metformin +Sulfonyl Ureas + Others showed a good control of fasting blood sugar when compared with only Metformin, only Sulfonyl Ureas or Metformin +Sulfonyl Ureas, Sulfonyl Ureas + Others.
Conclusion: Metformin was the most utilized drug followed by glimiperide. Combination therapy was most frequent when compared to monotherapy in which metformin+glimiperide was commonly prescribed one. so by understanding  the current prescribing patterns attempts can be made to improve rational prescribing. The combination of Metformin+Sulfonyl Ureas+Others is more effective combination.

ABSTRACT
We aimed at assessing the effect of methanolic extract of Streblus asper in human red blood cell (HRBC) membrane stabilization and insecticidal (on the stored grain pest, Trogoderma  granarium Everts) as studies. The membrane stabilizing activity was assessed by using erythrocyte in hypotonic solution and heat induced was compared with acetyl salicylic acid. The extract at the doses of  200, 400 and 800 μg/ml significantly inhibited heat induced lysis of the human red blood cell membrane with values of 46.53%, 56.52% and 65.14%, respectively. The results of hypotonic solution induced lysis showed that S. asper has significant reduction (P≤0.01) in inflammation i.e. 40.8 % (400 µg/ml) and 50.8 % (800 µg/ml) as compared to the standard drug, acetyl salicylic acid, which was 62.96 % in insecticidal assay the extract showed dose dependent paralyzing effect and mortality of T.  granarium Everts. All the doses of crude extracts exhibited concentration and time dependent insecticidal activity.

ABSTRCT
Simvastatin is a poorly soluble drug exhibiting poor dissolution pattern. Simvastatin, PEG 6000 & Poloxamer 407 solid dispersions were prepared with a view to study the influence of polymer on solubility and dissolution of this poorly soluble drug Simvastatin. Solid dispersions of Simvastatin were prepared using different ratios of PEG 6000 & Poloxamer 407 as carrier by, solvent evaporation method. They were evaluated for percentage yield, drug content, FTIR spectral studies, DSC, XRD, solubility, and in-vitro dissolution. The solubility profile indicated that there is increase in solubility of Simvastatin when polymer concentration is increased. The solid dispersion complex of drug (1:5:5 ratios) was giving better dissolution profile as compared to pure drug and other solid dispersions. This in turn can improve the bioavailability. FT-IR, DSC shows the compatibility of drug and carrier.
