Nitrostat, Nitro-Bid, Tridil

nitrate, anti-anginal, vasodilator

• Antianginal relaxes vascular smooth muscle of both venous and arterial beds, resulting in a net decrease in the myocardial oxygen consumption. It also dilates coronary vessels, leading to redistribution of blood flow to ischemic tissue and improves collateral circulation
• Vasodilating dilates peripheral vessels, decreasing venous return to the heart (preload) useful in treating pulmonary edema and heart failure. Arterial vasodilation decreases afterload, thereby decreasing
• left ventricular work and aiding the failing heart

Asprine, Alka Seltzer, Aspergum, Bayer, Cosprin....

• Anit-infammatory
• analgesic
• antipyretic
• platelet inhibitor

• Anticoagulant: at low doses, appears to impede clotting by blocking prostaglandin synthesis, which prevents
• formation of platelet-aggregating substance thromboxane A2
• Analgesia/anti-inflammatory: inhibits the synthesis of prostaglandin, preventing or reducing pain (this is irreversible and can prolong bleeding time)
• Antipyretic: acts on the hypothalamus to produce peripheral vasodilation causing sweating which leads to heat loss and cooling by evaporation
