Drug Name Zovirax

The narrow therapeutic margin can be explained by the mechanism of action. Cardiac glycosides (CG) bind to the extracellular side of Na+/K+-ATPases of cardiomyocytes and inhibit enzyme activity. The Na+/K+-ATPases operate to pump out Na+ leaked into the cell and to retrieve K+ leaked from the cell.
Myocardial infarction is caused by acute thrombotic occlusion of a coronary artery (A). Therapeutic interventions aim to restore blood flow in the occluded vessel in order to reduce infarct size or to rescue ischemic myocardial tissue. In the area perfused by the affected vessel, inadequate supply of oxygen and glucose impairs the function of heart muscle: contractile force declines.

 

The FeIII-P450-RH binary complex is first reduced by NADPH, then forms the ternary complex, O2-FeII-P450-RH, which accepts a second electron and finally disintegrates into FeIII-P450, one equivalent of H2O, and hydroxylated drug (R-OH).
linical studies In vivo studies have been performed on oral fast-disintegrating dosage forms to investigate their behavior in the oral–esophageal tract, their pharmacokinetic and therapeutic efficacy, and acceptability. Zydis’s residence time in the mouth and stomach, and its transit through the esophageal tract, was investigated using gamma-scintigraphy.
