Uses

1 INDICATIONS AND USAGE Atropine Sulfate Injection, USP, is indicated for temporary blockade of severe or life threatening muscarinic effects, e.g., as an antisialagogue, an antivagal agent, an antidote for organophosphorus or muscarinic mushroom poisoning, and to treat bradyasystolic cardiac arrest. These highlights do not include all the information needed to use ATROPINE SULFATE INJECTION safely and effectively. See full prescribing information for ATROPINE SULFATE INJECTION. ATROPINE SULFATE injection, for intravenous use Initial U.S. Approval: 1960

Dosage

2 DOSAGE AND ADMINISTRATION 2.1 General Administration Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer unless solution is clear and seal is intact. Each syringe is intended for single dose only. Discard unused portion. For intravenous administration. Titrate based on heart rate, PR interval, blood pressure and symptoms.

Side Effects

6 ADVERSE REACTIONS The following adverse reactions have been identified during post-approval use of atropine sulfate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Most of the side effects of atropine are directly related to its antimuscarinic action. Dryness of the mouth, blurred vision, photophobia and tachycardia commonly occur. Anhidrosis can produce heat intolerance. Constipation and difficulty in micturition may occur in elderly patients. Occasional hypersensitivity reactions have been observed, especially skin rashes which in some instances progressed to exfoliation. To report SUSPECTED ADVERSE REACTIONS, contact Medefil, Inc.

Interactions

7 DRUG INTERACTIONS 7.1 Mexiletine Atropine Sulfate Injection decreased the rate of mexiletine absorption without altering the relative oral bioavailability; this delay in mexiletine absorption was reversed by the combination of atropine and intravenous metoclopramide during pretreatment for anesthesia.

Warnings

5 WARNINGS AND PRECAUTIONS 5.1 Tachycardia When the recurrent use of atropine is essential in patients with coronary artery disease, the total dose should be restricted to 2 to 3 mg (maximum 0.03 to 0.04 mg/kg) to avoid the detrimental effects of atropine-induced tachycardia on myocardial oxygen demand. 5.2 Acute Glaucoma Atropine may precipitate acute glaucoma. 5.3 Pyloric Obstruction Atropine may convert partial organic pyloric stenosis into complete obstruction. 5.4 Complete Urinary Retention Atropine may lead to complete urinary retention in patients with prostatic hypertrophy. 5.5 Viscid Plugs Atropine may cause inspissation of bronchial secretions and formation of viscid plugs in patients with chronic lung disease. 4 CONTRAINDICATIONS None.
