NALOXONE NIFEDIPINE NITROGLYCERIN Name/Class: NALOXONE (Narcan)/Narcotic Antagonist Description: Naloxone is a pure narcotic antagonist that blocks the effects of both natural and synthetic narcotics and may reverse respiratory depression. Indications: Narcotic and synthetic narcotic overdose, coma of unknown origin. Contraindications: Hypersensitivity to the drug, non–narcotic-induced respiratory depression. Precautions: Possible dependency (including newborns). It also has a half-life that is shorter than that of most narcotics; hence the patient may return to the overdose state. Dosage/Route: 0.4 to 2 mg IV/IM (2 to 2.5 times the dose ET), repeated/2 to 3 min as needed up to 10 mg. Ped: 0.01 mg IV/IM (2 to 2.5 times the dose ET) repeated/2 to 3 min as needed up to 10 mg. Name/Class: NIFEDIPINE (Procardia, Adalat)/Calcium Channel Blocker Description: Nifedipine is a calcium channel blocker that reduces coronary artery spasm in angina. It also decreases peripheral vascular resistance, blood pressure, and cardiac workload. Indications: Severe hypertension and angina. Contraindications: Hypersensitivity or hypotension. Precautions: Monitor blood pressure carefully, since it can drop significantly with nifedipine use. Dosage/Route: One 10 to 20 mg capsule SL/PO. Name/Class: NITROGLYCERIN (Nitrostat)/Nitrate Description: Nitroglycerin is a rapid smooth muscle relaxant that reduces peripheral vascular resistance, blood pressure, venous return, and cardiac workload. Indications: Chest pain associated with angina and acute myocardial infarction, and acute pulmonary edema. Contraindications: Hypersensitivity, tolerance to nitrates, severe anemia, head trauma, hypotension, increased ICP, patients taking sildenafil, glaucoma, and shock. Precautions: May induce headache that is sometimes severe. Nitroglycerin is light sensitive and will lose potency when exposed to the air. Dosage/Route: 1 tablet (0.4 mg) SL. May be repeated/3 to 5 min up to 3 tablets, or 1⁄2 inch of topical ointment, or 0.4 mg (one spray)SL up to 3 sprays/25 min.
