Drug Name: Crestor (Rosuvastatin)

Tissues that have a physiologically high mitotic rate are bound to be affected by cytostatic therapy.
In pacemaker fibers, diastolic depolarization is hastened, so that the firing threshold for the action potential is reached sooner (positive chronotropic effect, B). The cardiostimulant effect of ?-sympathomimetics such as epinephrine is exploited in the treatment of cardiac arrest. Use of ?- sympathomimetics in heart failure carries the risk of cardiac arrhythmias.

 

The van der Waals’ bond, therefore, is a form of electrostatic attraction, albeit of very low strength (inversely proportional to the seventh power of the distance). Hydrophobic interaction (C). The attraction between the dipoles of water is strong enough to hinder intercalation of any apolar (uncharged) molecules.
Thus, the nitrates enable myocardial flow resistance to be reduced even in the presence of coronary sclerosis with angina pectoris. In angina due to coronary spasm, arterial dilation overcomes the vasospasm and restores myocardial perfusion to normal.
