Anticoagulants are a class of drugs commonly used to prevent the blood from forming dangerous clots that could result in a stroke.Warfarin is an oral anticoagulant. Warfarin differs from most other drugs in that the dosage required to achieve a desired therapeutic effect varies greatly among individuals. Resistance to warfarin has been described as the inability to prolong the prothrombin time or ...
STUDY OF THE EFFECT OF SODIUM VALPROATE ON ENHANCEMENT OF MONOAMINE MEDIATED BEHAVIOURAL RESPONSES AFTER ELECTROCONVULSIVE SHOCK (ECS) ADMINISTRATION IN RATS
Objectives: To obtain the data regarding the effects of sodium valproate on enhancement of monoamines mediated behavioural responses following administration of ECS for ten days to rats. Methods: Forty rats were selected for the study in which tonic-clonic seizures were developed fully after giving single maximal electroconvulsive shock (150V, 210mA). Four groups (n= ten in each) were received dif...
RP-HPLC METHOD DEVELOPMENT AND VALIDATION OF STABILITY INDICATING METHOD A FOR ESTIMATION OF LOSARTAN POTASSIUM UNDER STRESS CONDITION AND TABLET DOSAGE FORM
Losartan potassium, a highly effective blood pressure lowering agent, has widely used for treatment of hypertension. Simple, economic, selective, and precise and stability indicating HPLC method has been developed and validated for analysis of losartan potassium in bulk drug and formulation dosage form. In order to optimize more one response at time, the chemo metric approach which includes 23...
A study on biological monitoring of simultaneous exposure to benzene and alcohol was made in petrol pump operators of Meerut city (India). In addition to alcohol, other confounding factors viz. cigarette smoke, food habit, age and work experience were also considered. Thirty two, 20-40 years old male workers were registered for this study. Respective urine samples collected after the workshift wer...
SIMULTANEOUS STABILITY-INDICATING METHOD FOR THE DETERMINATION OF ABACAVIR, DOLUTEGRAVIR AND LAMIVUDINE BY RP-HPLC
A simultaneous stability-indicating reversed-phase high performance liquid chromatography (HPLC) method for analysis of abacavir (ABC), dolutegravir (DTG) and lamivudine (3TC) as the bulk drug and in the formulation was developed. Compounds were separated on Kinetex 5 µ C18 100 A (250 mm x 4.6 mm). A gradient program of mobile phase at different proportions of acetonitrile (ACN) and water was use...
Due to the increasingly tight controls around compliance, pharmaceutical firms continue to seek more efficient ways to track, document and report on code changes in regulated applications such as those developed for managing samples and inventory. Such applications and electronic signatures associated with application development and workflows are subject to stringent regulations such as Sarbanes-...
Stroke remains world’s second leading cause of mortality; and globally most frequent cause of long-lasting disabilities. The ischaemic pathophysiologic cascade leading to neuronal damage consists of peri-infarct depolarization, excitotoxicity, inflammation, oxidative stress, and apoptosis. Despite plethora of experimental evidences and advancement into the development of treatments, clinical tre...
Fertility control is an issue of global challenge. Researchers are trying to develop male herbal contraceptives from natural sources. Jussiaea repens L (JR) is such an herb which is reported to have non toxic antigonadal activity in male rats. The present study has designed to evaluate whether crude queous extract of JR affects the DNA integrity of spermatozoa and also to study whether its actions...
As described by the world health organization (WHO), depression is the most common and serious disorder leading to suicide. Numbers of synthetic drugs are available for the treatment of this fatal disease, but are associated with serious complications. A wide diversity of animal models has been used to examine antidepressant activity. These range from relatively simple models sensitive to acute tr...
SIMULTANEOUS DETERMINATION TRACE LEVELS OF VITAMIN B1 AND VITAMIN B9 IN HUMAN SAMPLES BY ULTRASOUND-ASSISTED DISPERSIVE LIQUID-LIQUID MICROEXTRACTION COUPLED WITH HPLC-UV
Ultrasound-assisted dispersive liquid-liquid micro extraction (UA-DLLME) was proposed for simultaneous determination of trace levels of Vitamin B1 (thiamine) and Vitamin B9 (folic acid) in the human urine and serum samples. High performance liquid chromatography (HPLC) coupled with chemometrics method was employed to analysis the extraxtants. Objective: The optimal conditions of the extraction rec...
