Nitroglycerin (NTG)
Nitroglycerin is used medically as a vasodilator to treat heart conditions, such as angina and heart failure. It is one of the oldest and most useful drugs for treating heart disease by shortening or even preventing attacks of angina. Nitroglycerin comes in forms of tablets, sprays or patches.
Blood returning from the body in the veins must be pumped by the heart through the lungs and into the arteries against the high pressure in the arteries. In order to accomplish this work, the heart’s muscle must produce and use energy (“fuel”). The production of energy requires oxygen. Angina pectoris (angina) or “heart pain” is due to an inadequate flow of blood (and oxygen) to the muscle of the heart. It is believed that all nitrates, including nitroglycerin, correct the imbalance between the flow of blood and oxygen to the heart and the work that the heart must do by dilating (widening) the arteries and veins in the body. Dilation of the veins reduces the amount of blood returning to the heart so that the heart does less work and requires less blood and oxygen. Dilation of the arteries also lowers the pressure in the arteries against which the heart must pump. As a consequence, the heart works less and requires less blood and oxygen.
Nitroglycerin (NTG) tablets placed under the tongue, is a very effective means of treating angina. The tablet dissolves under the tongue and may have a slightly sharp, burning or tingling taste. Tablets which have this taste when fresh but subsequently become tasteless may indicate loss of effectiveness and potency.
ACE Inhibitors
ACE Inhibitors (Angiotensin-Converting Enzyme Inhibitors) are drugs used to treat high blood pressure and heart failure.
ARBs
Angiotensin II Receptor Blockers (ARBs) are drugs most often prescribed for people who experience side effects with ACE inhibitors.
Beta Blockers
Beta Blockers are drugs that slow the heart rate, decrease cardiac output, lessen the force with which the heart muscle contracts and reduce blood vessel contraction.
Calcium Channel Blockers
Calcium Channel Blockers are drugs that block the movement of calcium into heart and blood vessel muscle cells, which can decrease the pumping strength of the heart and relax blood vessels.
This causes the muscles to relax, lowering blood pressure, slowing the heart rate and decreasing oxygen demands of the heart. They are used to treat high blood pressure and chest pain (angina) caused by reduced blood supply to the heart muscle, as well as some abnormal heart rhythms (arrhythmias).
Some noted possible side effects of calcium channel blockers:
Diuretics
Diuretics (often called water pills) are drugs that cause the body to rid itself of excess fluids and sodium through urination.
