The aim of the present study was to prepare and characterize the Sustained release matrix tablets of Ranolazine using Kollidon® SR. Kollidon® SR is a polyvinyl acetate based excipient. Three different strengths i.e 375mg, 500mg and 750mg of ranolazine SR tablets were prepared by direct compression method and by using common blend. The influence of compression force was studied on the dissolutio...
Na(V)1.5 is a mechanosensitive voltage-gated Na(+) channel encoded by the gene SCN5A, expressed in cardiac myocytes and required for phase 0 of the cardiac action potential (AP). In the cardiomyocyte, ranolazine inhibits depolarizing Na(+) current and delayed rectifier (I(Kr)) currents. Recently, ranolazine was also shown to be an inhibitor of Na(V)1.5 mechanosensitivity. Stretch also accelerat...
Introduction A major determining factor on outcomes in patients with pulmonary arterial hypertension (PAH) is right ventricular (RV) function. Ranolazine, which is currently approved for chronic stable angina, has been shown to improve RV function in an animal model and has been shown to be safe in small human studies with PAH. We aim to study the effect of ranolazine on RV function using cardi...
Reactive oxygen species (ROS), including H2O2, cause intracellular calcium overload and ischemia-reperfusion damage. The objective of this study was to examine the hypothesis that H2O2-induced arrhythmic activity and contractile dysfunction are the results of an effect of H2O2 to increase the magnitude of the late sodium current (late INa). Guinea pig and rabbit isolated ventricular myocytes we...
سابقه و هدف: etomoxir و ranolazine از داروهای جدید با اثرات عمده متابولیک هستند که در درمان بیماریهای ایسکمیک قلب مورد توجه قرار گرفته اند. هدف از این مطالعه اثرات ضد آریتمی این داروها در قلب ایزوله موش صحرائی می باشد.مواد و روشها: مطالعه به صورت تجربی بر روی موشهای صحرائی نر (نژاد sprague dawley) با محدوده وزنی 330-270 گرم انجام شد. موشها به سه گروه 10 تایی (شامل گروه کنترل، گروه تحت درمان با ...
BACKGROUND Incomplete revascularisation is common after percutaneous coronary intervention and is associated with increased mortality and adverse cardiovascular events. We aimed to assess whether adjunctive anti-ischaemic pharmacotherapy with ranolazine would improve the prognosis of patients with incomplete revascularisation after percutaneous coronary intervention. METHODS We performed this...
Chronic stable angina is a debilitating illness affecting at least 6.6 million US residents. Despite being optimally treated by pharmacotherapy and revascularization up to 26% of patients still experience angina. Diabetes mellitus is a common co-morbid condition in angina patients. Several new investigational medications are being tested for chronic angina. Advances in understanding of myocardi...
Reduction of repolarization reserve increases the risk of arrhythmia. We hypothesized that inhibition of K(+) current (I(K)) to decrease repolarization reserve would unmask the proarrhythmic role of endogenous, physiological late Na(+) current (late I(Na)). Monophasic action potentials (MAP) and 12-lead electrocardiogram were recorded from female rabbit isolated hearts. To block I(K) and reduce...
