Atropine
Atropine
An anticholinergic medication used for treating bradycardia and various other medical conditions.
Symptomatic Bradycardia
Symptomatic Bradycardia
A condition where the heart beats slower than 60 beats per minute causing symptoms like confusion and fainting.
Therapeutic Uses of Atropine
Therapeutic Uses of Atropine
Treats bradycardia, dries secretions before surgery, acts as an antidote for poison, and helps with bronchospasm.

Study Notes
Atropine Medication Information
-
Therapeutic Use: Treats symptomatic bradycardia (low heart rate); used prior to surgery to dry up respiratory secretions; antidote for pesticide or chemical warfare agent poisoning; treats bronchospasm; blocks acetylcholine receptors in the GI tract, lungs, and eyes.
-
Adverse Reactions: Tachycardia, paradoxical bradycardia, hypotension, hypertension, atrial/ventricular fibrillation, spasms of the larynx; dry mouth, blurred vision, urinary retention, decreased gastric motility, constipation, headache, drowsiness, sedation, respiratory depression, dizziness, disorientation, hallucinations.
-
Interventions: Monitor heart rate and rhythm (tachycardia and paradoxical bradycardia). Monitor for increased anticholinergic effects. Prepare to administer other medications (dopamine, epinephrine) or provide transcutaneous pacing, if atropine is ineffective.
-
Administration: Subcutaneous, intramuscular, intraosseous, endotracheal, or intravenous (IV) injection. IV bolus is preferred for severe bradycardia. Dose: 1 mg IV bolus, repeatable every 3-5 minutes up to 3 mg; administer rapidly to prevent paradoxical slowing of the heart. Explain the medication and monitor continuously.
-
Client Instructions: Report dizziness, chest pain, or difficulty breathing immediately.
Contraindications
- Life-threatening situations: Atropine is not contraindicated in life-threatening situations.
- Hypersensitivity: Atropine is contraindicated in clients with known hypersensitivity.
- Glaucoma: Contraindicated in clients with glaucoma.
- Obstructive Disorders: Contraindicated in obstructive disorders of the bladder or Gl tract, or prostate.
- Myasthenia Gravis: Contraindicated in clients with myasthenia gravis.
- Tachycardia Due to Cardiac Insufficiency: Contraindicated in clients with tachycardia due to cardiac insufficiency.
- Heart Transplant: Do not administer to clients who have had a heart transplant, as atropine is ineffective due to the loss of nerve supply to the sinus node.
Precautions
- COPD and Heart Disorders: Use caution when administering atropine to clients with COPD, CAD, MI, heart failure, tachycardia, or hypertension, as it can increase heart rate and workload.
Interactions
- Additive Effects: Atropine can have additive effects with other anticholinergics, antiparkinsonian drugs, antihistamines, muscle relaxants, meperidine, phenothiazines, procainamide, tricyclic antidepressants.
- Digoxin: Atropine can increase digoxin levels.
- Reversal Agent: Physostigmine is the reversal agent for atropine or anticholinergic toxicity.
