Isordil is a brand name for isosorbide dinitrate, which is used to prevent and treat angina pectoris and congestive heart failure. It works by relaxing both arterial and venous blood vessels, which decreases oxygen demand on the heart and improves blood flow. Common side effects include flushing, headaches, and low blood pressure. Nurses should educate patients to avoid chewing or crushing sublingual tablets and to maintain a nitrate-free interval each day to prevent tolerance.

Brand name: Isordil
Generic name: Isosorbide dinitrate
Indication: prevention and treatment of angina pectoris, for congestive heart failure, to relieve pain, dysphagia and spasm in esophageal spasm with GE reflux. Drug classification: antianginal agent, nitrate, vasodilator, coronary Mechanism of action: stimulation of intracellular cystic- GMP results in vascular smooth muscle relaxation of both arterial and venous vasculature. Increased venous pooling decreases ventricular pressure (pre-load) and arterial dilatation decreases arterial resistance (afterload). Therefore this reduces cardiac oxygen demand by decreasing left ventricular pressure and systematic vascular resistance by dilating arteries. Additionally, coronary artery dilation improves collateral flow to ischemic regions; esophageal smooth muscle is relaxed via the same mechanism. Dosage: angina pectoris oral 5-30mg qid. Sublingual 5-10mg 2-3 hourly. Acute CHF oral 10- 40mg qid. Sublingual 5-10mg 2 hourly. chronic CHF initially 5-10 mg daily 2 hourly sublingually. maintenance 20-40mg qid orally. Special precaution: tolerance and cross tolerance to other nitrate and nitrites may occur. Pregnancy, lactation and children. Patients prone to or affected by hypotension or vol. depletion; severe hypotensive response; paradoxical bradycardia, increased angina may accompany nitrate induced hypotension, hypertrophic cardiomyopathy. Pregnancy risk factor: C Adverse reactions: flushing, vascular headache, cerebral ischemia associated with postural hypotension, nausea, vomiting, weakness, restlessness, palor, perspiration and collapse, drug rash and or exfoliative dermatitis. Contraindications:hypersensitivity Form: tab 5mg x 100s, 500s; 10mg x 100s, 500s Sublingual tab 5mg x 100s Nursing responsibilities: Inform or educate patient not to chew crush sublingual or sustained release dosage form Do not change brands without consulting the physician or pharmacist, keep tablets or capsules in original container tightly closed. 8 to 12 hour nitrate free interval is needed each day to prevent tolerance
