Protect drug from sunlight to maintain drug potency.Ask for presence of burning sensation to ensure drug potency.If the pain does not subside, seek medical help. Take three tablets with a 5-minute interval, for a total of three doses. Instruct patient not to swallow sublingual preparations to ensure therapeutic effects.Ineffective Tissue Perfusion related to low oxygen supply to myocardial cells.Risk for Injury related to adverse effects on neurological and cardiovascular status.Decreased cardiac output related to vasodilation and hypotensive effects of the drug.CBC, liver and kidney function tests, etc.)

Cardiopulmonary status (BP take heart rate in full minute).

Neurological status (level of consciousness, affect, reflexes, etc.).

Skin color and integrity, especially for transdermal or topical forms of nitrates.Presence of mentioned contraindications and cautions.PDE-5 inhibitors: risk for severe hypotension.Heparin: decreased therapeutic effect of nitrates.Ergot derivatives: risk for hypertension decreased antianginal effect.Large dose leads to methemoglobinemia and cyanosis.CV: hypotension, reflex tachycardia, syncope.CNS: throbbing headache, dizziness, weakness.Hepatic and renal disease – alteration in drug metabolism and excretion.Pregnancy and lactation – potential harm to fetus.

Head trauma and cerebral hemorrhage – relaxation of cerebral vessels can lead to intracranial bleeding.Severe anemia – decreased cardiac output (CO) caused by nitrates is dangerous for blood with low-oxygen binding capacity.Allergy to nitrates – prevent hypersensitivity reactions.

Continuous infusion or transdermal patch for unstable angina.

Sublingual nitroglycerin is most effective for recurrent variant angina.

Use during pregnancy is not established.

They should receive initial low dose because of probably hepatic and renal impairments which can interfere with metabolism and excretion of drugs.

Older adults: Safety measures should be instituted as they are prone to adverse effects like arrhythmias and hypotension.

Lifestyle modifications such as smoking cessation, low-fat diet, and weight loss should be encouraged to promote effectiveness of Antianginal therapy.

Adults: Should be educated on drug’s various forms and their proper administration, storage, effectiveness, and manifestations that would warrant prompt medical help.

Children: May be used only for congenital heart defects and cardiac surgery because they can cause potentially dangerous changes in blood pressure.

It compensates by increasing blood flow to healthy arteries and veins because affected vessels already lose their elasticity.

The main effect is drop in systemic blood pressure.

Both of these actions lower oxygen demand by decreasing the workload of the heart. Also, they reduce afterload by dilating the arteries.

Nitrates reduce preload and myocardial muscle tension by dilating the veins.

Nitrates are antianginal agents that provide fast action to directly relax smooth muscles and depress muscle tone without affecting nerve activity.

Both types decrease oxygen supply of the heart. vasospastic/Prinzmetal’s/variant angina, which is caused by reversible vasospasm even at rest.classic angina (of exercise), which occurs due to diminished coronary blood flow to the heart and.As a consequence of hypoxia, pain ( angina) is felt.The heart stimulates the blood vessels to deliver more blood but blood delivery is limited by narrow vessel diameter, resulting to low oxygen supply of the heart. The vessels also lose their natural ability to be elastic, resulting to inability to dilate and constrict. This pathologic process attracts platelets and clotting factors to the area, causing a much larger obstruction to the vessels.isosorbide dinitrate (Isordil, Sorbitrate)ĭisease spotlight: Coronary Artery DiseaseĬoronary Artery Disease (CAD) is the narrowing of blood vessels supplying oxygen and nutrients to the heart, primarily due to the development of fatty tumors (atheromas) in the lumen of blood vessels in a process called atherosclerosis.isosorbide mononitrate (Imdur, Monoket).Disease spotlight: Coronary Artery DiseaseĪntianginal Drugs: Generic and Brand Names.Antianginal Drugs: Generic and Brand Names.
