    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
