Nitroglycerin MEDICATION __________________________________________________________________________ REVIEW MODULE CHAPTER ___________ antianginal agent CATEGORY CLASS ______________________________________________________________________ PURPOSE OF MEDICATION

Expected Pharmacological Action -in chronic stable exertional angina, nitroglycerin dilates veins and decrease venous return(preload) which decreases cardiac oxygen. -In Prinzmetals or vasospastic angina, nitroglycerin prevents or reduces coronary atery spasm, thus increasing oxygen supply. Oxygen is not decreased.

Therapeutic Use -treatment of acute angina attack -prophylaxis of chronic stable angina or variant angina.

Complications -headache -orthostatic hypotension -reflex tachycardia -tolerance

Medication Administration - oral extended release capsules -sublingual tablet -translingual spray -topical ointment -transdermal patch -intravenous

Contraindications/Precautions -pregnancy risk category B for tablets and category C for capsules,IV, spray,ointment,patch. -contraindicated for clients who have hypersensitivity to nitrates. -contraindicated in clients who have severe anemia, closed angle glaucoma and traumatic head injury, med can increase intracranial pressure. -use cautiously in clients taking antihypertensive meds and have hyperthyroidism or kidney or liver dysfunction. -inhibitors of phoshodiesterase type 5 for ED administered w/nitroglycerin can intensify the nitroglycerin induces vasodilators and result in life threatening hypotension

Interactions

Nursing Interventions -provide continuous cardiac and bloop pressure monitoring. - use lowest dose needed to achieve effect. -monitor vital signs

-use of alcohol can contribute to the hypotensive effect -antihypertensive meds (beta blockers, calcium channel blockers, diuretics) can contribute to hypotensive effect. Client Education Evaluation of Medication Effectiveness -prevention and termination of acute anginal attacks. - long-term management of stable angina -control of perioperative blood pressure. -control of heart failure following acute MI.

ACTIVE LEARNING TEMPLATES

do not crush or chew oral nitrogylcerin tablets or sublingual is ineffective if swallowed -stop taking long acting nitroglycerin abruptly. -place patch on hairless area of skin and rotate sites. -remove patch at night to reduce risk of developing tolerance. Be medication free 10-12hr/day....
