Question

Quizplus · Accepted Answer

Papaverine HCl is a potent vasodilator that is commonly used by peripheral vascular and neurosurgeons to dilate blood vessels intraoperatively. It works by relaxing the smooth muscle in the walls of blood vessels, which increases blood flow and reduces vascular resistance. Lidocaine HCl is a local anesthetic and antiarrhythmic agent, epinephrine is a sympathomimetic drug that constricts blood vessels and increases heart rate and blood pressure, and heparin is an anticoagulant that prevents blood clots from forming. While all of these drugs may be used in certain surgical procedures, none of them have the specific vasodilatory effects of papaverine HCl.
