Study Notes
Anticholinergic Drugs
- Main effect: Inhibit the action of acetylcholine, a neurotransmitter that stimulates muscle contractions and secretions.
- Adverse effect: Dry mouth, blurred vision, urinary retention, constipation, and tachycardia.
- Contact doctor: When experiencing adverse effects, such as difficulty urinating or allergic reactions.
- Antidote: Physostigmine, which reverses the effects of anticholinergic overdose.
- Effect on heart rate: Increases heart rate.
- Contraindication: Glaucoma, as anticholinergic drugs can increase intraocular pressure.
- Effect on glaucoma patients: Worsening of glaucoma symptoms.
- Role of Atropine: Blocks the action of acetylcholine, used to treat bradycardia, organophosphate poisoning, and as a pre-anesthetic medication.
- Main effect: Inhibit the parasympathetic nervous system, reducing secretions and muscle contractions.
Indications and Contraindications
- Dicyclomine/Bentyl: Used to treat irritable bowel syndrome (IBS).
- Anticholinergic medication for overactive bladder: Oxybutynin, Tolterodine, or Solifenacin.
- Scopolamine: Used to treat motion sickness, nausea, and vomiting.
- Pre-surgical use: Glycopyrrolate/Robinul, used to reduce secretions and prevent bronchospasms.
- Primary role of Glycopyrrolate/Robinul: Reduces secretions and prevents bronchospasms during surgery.
Effects on the Body
- Affects the parasympathetic nervous system: Reduces secretions and muscle contractions.
- Effect on the internal sphincter: Relaxes the internal sphincter, increasing the risk of urinary retention.
- Potential risk: Increased risk of heat stroke, especially in elderly patients.
- Dry mouth: Anticholinergic drugs can dry out the mucous membranes, causing dry mouth.
Conditions Treated
- Overactive bladder
- Irritable bowel syndrome (IBS)
- Motion sickness
- Nausea and vomiting
- Bradycardia
- Organophosphate poisoning
