A simple, fast and precise reverse phase high performance liquid chromatographic method has been developed for the simultaneous determination of Fexofenadine hydrochloride (FEXO) and Montelukast Sodium (MONT). Efficient chromatographic separation was achieved on phenomenex C18 column (150mm x 4.6 mm, 5 μm) as stationary phase with a mobile phase comprising of 0.5% Orthophosphoric acid pH adjusted to 6 (tri ethyl amine): Acetonitrile(40:60 v/v) at a flow rate of 1.0mL min-1, column temperature of 25°C and UV detection at 240 nm. The retention time of and Fexofenadine hydrochloride and Montelukast Sodium were 2.7 min, and 4 min respectively .The linearity were found to be in the range of 72-120 μg/ml and 6-10 μg/ml Fexofenadine Hydrochloride and Montelukast Sodium respectively with correlation co efficient of 0.999. The proposed method was validated for linearity, accuracy, precision, sensitivity. All validation parameters were within the acceptable range. The developed method was successfully applied to estimate the amount of Fexofenadine hydrochloride and Montelukast Sodium in combined dosage...

In the present study, three algal species (Spirulina platensis, Chlorella pyrenoidosa and Nostoc muscorum (ATCC 2789) were used to investigate their antimicrobial and antioxidant properties against some human pathogenic bacteria and fungi (Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Micrococcus luteus and fungus Aspergillus luchuensis, Aspergillus niger, Fusarium oxysporum). Four different solvents namely methanol, acetone, n-hexane and water were used for extraction. The present investigation showed that methanolic extract was more effective against the pathogenic bacteria and fungi. Methanolic extract of C. pyrenoidosa and N. muscorum was found to be most effective against P. aeruginosa while methanolic extract of S. platensis showed maximum activity against S. aureus. S. platensis showed maximum antifungal activity in comparison to other algal extracts. Antioxidant activity was determined by free radical scavenging activity (Nitric oxide radical scavenging activity) and it was found that methanolic extract of S. platensis showed maximum antioxidant...

Chronic myeloid leukemia (CML) is a malignancy of hematopoietic stem cells associated with a t(9;22) translocation that forms the Philadelphia chromosome and creates a novel fusion gene, BCR-ABL. For those who are resistant or intolerant to imatinib, second-generation tirosino-kinase inhibitor, as dasatinib, has been shown to be efficacious in all phases of the disease. Once dasatinib is taken orally and the treatment has no defined end point, a complete follow up method, including a pharmacotherapy follow up, to monitor the CML patients is essential to define adherence and treatment safety. To systematically review follow up methods of CML patients treated with dasatinib in clinical trials (CT) either randomized (RCT), or not (NRCT) and prospective cohorts (PC) a sensitized research was performed on the databases Medline (Pubmed), Cochrane Library (OVID), Embase (Elsevier) and Lilacs. Four RCT, four NRCT and three PC were identified and contained data about patients follow up, which proved to be well established and structured. Adverse drug reactions grades III and IV description was in accordance with...

Tuberculosis (TB) is a growing international health concern and it is estimated that a third of the world’s population is currently infected with TB. The increasing prevalence of multidrug-resistant (MDR)-TB has greatly increased difficulties in its treatment and control. Therefore, the present study was perceived to check the status of tuberculosis at Kanpur, one of the largest city of Uttar Pradesh and oldest industrial townships of North India. Study was also aimed to understand the expectation and mindset of community/patients regarding the services of a pharmacist in the maintenance or restoration of health. The study was conducted on the TB patients attending different outpatient and or inpatient department of local and government hospital, clinics, in Kanpur city and necessary information had been collected through questionnaire by making couple of visit and follow-up counseling. It was amazing to know through the study that knowledge and awareness about such common and chronic diseases was either very poor or there was none implementation for prevention and control. The healthcare services of pharmacist...

Co(II), Ni(II) and Zn(II) complexes of Schiff bases derived from condensation of 4-anisaldehyde with anisidine, (AAN) or 2,4 dinitrophenylhydrazine ,(ADN) have been prepared in 1:2 molar ratio (metal:ligand). The compounds have been characterized using elemental analysis, electronic spectra, infrared and molar conductance measurements. The infrared data revealed that the ligand, AAN behaved as a tridentate ligand. It coordinated to the metal ions via the N and two O atoms of the ligand. ADN behaved as a bidentate ligand coordinating through the O and N atoms of the ligand. The electronic spectral data indicates that the compounds are six coordinate. The molar conductance values showed that the complexes are non-electrolytes. The compounds were screened in vitro for antibacterial activity against some pathogenic bacteria: Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Bacillus subtilis and Staphylococcus aureus using the agar-well diffusion method. The synthesized Schiff base complexes exhibit higher antibacterial activity against the tested pathogens compared to the free Schiff base because of...
