A highly sensitive, simple, accurate and precise HPLC-ESI-MS/MS method was developed and validated for the quantitative determination of talazoparib in biological matrices. The present study describes the determination of Talazoparib using validated protein precipitation method from human plasma employing Talazoparib 13C D4 as internal standard by electron spray ionization technique. Combination of 0.1% v/v formic acid and methanol (25:75) % v/v was used as mobile phase. Ascentis Express C18 (50 mm × 4.6 mm, 2.7 µm) column was employed for the separation and the run time was 3 minutes. Flow rate was set at 0.6 ml/min and column oven temperature at 40°C for the chromatographic separation method. 10µl injection volume was selected for mass spectrometer to obtain good ionisation. Parent (Q1) and Product (Q3) ion mass transitions for Talazoparib and Talazoparib-13C-D4 were found at m/z 381.5®180.5 and 386.4®180.5 respectively. The linear regression data for the calibration plot showed a good relationship with high correlation coefficient. Correlation coefficient (r2) value from the standard curve (5-10000 pg/ml) found to be more...

Hydrophobic medications that are taken orally having poor bioavailability due to permeability issues. They experience a chemical and enzymatic breakdown in the digestive system and exhibit a significant amount of hepatic first-pass metabolism. Similar obstacles prevent the development of effective therapeutic molecule delivery systems and the discovery of new drugs. It has been revealing that curcumin, a key active lipophilic constituent of Curcuma longa (Zingiberaceae), has a variety of pharmacological properties, including cholagogues, anticancer, and anti-inflammatory properties. Based on its organoleptic characteristics, solubility, loss on drying, partition coefficient, infrared spectroscopy, and differential scanning calorimetry, Curcumin was physically and chemically characterized. The drug sample Curcumin was found to be genuine and pure based on the tests. For the purpose of determining in-vitro release and permeation study, an analytical method utilizing RP-HPLC was created and validated. Ionic gelation was used to create chitosan nanoparticles. The study includes the evaluation of various processing conditions, including surface morphology, particle size, particle size distribution, surface charge, percentage yield, entrapment efficiency, and drug loading, as...

Introduction: Adverse drug reactions (ADRs) poses an unforeseeable menace associated with all the prescribed medicines. Thus, ADRs are monitored and assessed on a large scale in our country by the Pharmacovigilance Programme of India through adverse drug reaction monitoring centres (AMCs). Objectives: This study was done to assess the pattern of ADRs reported in a tertiary care teaching hospital in Haryana by applying various aspects of ADR monitoring such as clinical presentation, causality, and severity assessment in various Inpatient departments at SHKM GMC. Material and Methods: A Prospective, Observational study was conducted in all the inpatient clinical departments of SHKM Govt. Medical College, Haryana for a duration of 12 months. ADRs were recorded in pre-designed proforma along with ADR reporting form “Version 1.3”. Processing & analysis of data was done using SPSS version 20. Results: A total of 189 ADRs among 120 patients were reported during the study period. Females were affected more than males. Maximum ADRs were reported in the age group of 19-60 years. ENT department had...

Actinomycetes are biotechnologically important microorganism as they produce many secondary metabolites and natural pigments, including a dark-brown pigment melanin. Melanin is produced in melanocytes that provides pigmentation to skin. Although many roles have been attributed to melanic pigments, the main role in nature seems to be photoprotection damage. Melanin possesses anti- UV radiation property by absorbing the electromagnetic spectrum and preventing optical damage in the living organisms. Melanoma is a malignant of melanocytes that controls the pigment melanin in the skin. The aim of the present study is to isolate the melanin producing actinomycetes from the agricultural soil and to assay the cytotoxicity using murine B16 melanoma cell line and normal mouse L929 fibroblast cell line. The results showed that the melanin obtained from the actinomycetes showed good anticancer activity against murine B16 melanoma cell line and nontoxic against normal mouse L929 fibroblast cell line. Hence it can be used as a photoprotective...

Introduction: Underreporting of adverse drug reactions (ADRs) in Pharmacovigilance programme of India (PvPI) may be due to lack of adequate knowledge, attitude and practice among healthcare professionals towards ADR reporting. Aim & Objective: Present study was planned to assess the knowledge, attitude and practices of ADR reporting amongst nursing staff of tertiary teaching hospital in Western Rural India. Methods: This was cross sectional, observational study in which about 527 Nursing staff from Tertiary teaching hospital in Western Rural India were participated. Study was conducted as per pre-validated google form questionnaire-based format to assess knowledge, attitude and practices of ADR reporting. Results: Out of total 527 nursing staff who filled the ADR survey questionnaire, 87.1% participants were aware of the term ADR and 82.5% were aware of the term Pharmacovigilance. Only 53.5% respondents have undergone training related to Pharmacovigilance & ADR reporting.54.8% nursing staff have faced ADR in a patient or themselves somewhere during their life time but only 46.5 % respondents have reported ADR. Most of nursing staff felt...
