Study Notes
Anticholinergic Drugs
- Anticholinergic drugs affect the autonomic nervous system, specifically the parasympathetic nervous system, and multiple organ systems, including the eye, heart, lung, urinary tract, and gastrointestinal tract.
Plant Used in Indian Medicine
- Datura stramonium, a plant, is used in Indian medicine to treat asthma symptoms.
Receptor Subtype Selectivity
- Synthetic derivatives of muscarinic antagonists show selectivity for the M3 receptor subtype.
Contraindication
- Unstable cardiovascular disease is a contraindication for the use of muscarinic antagonists.
Toxic Effects
- Xerostomia (dry mouth) is a toxic effect associated with muscarinic antagonists.
- Delirium is a toxic effect associated with muscarinic antagonists.
- Urinary retention is a toxic effect associated with muscarinic antagonists.
- The toxic effect NOT associated with muscarinic antagonists is bronchospasm.
Susceptible Population
- Older adults are particularly susceptible to the toxic effects of muscarinic antagonists.
Selective Drugs
- Darifenacin has the highest selectivity for the urinary bladder.
Elimination Route
- Tolterodine is primarily eliminated by the kidneys.
Therapeutic Applications
- Loperamide is used to treat diarrhea-predominant irritable bowel syndrome.
- Scopolamine is used prophylactically to prevent motion sickness.
Pharmacological Effects on Urinary Tract
- Atropine relaxes the detrusor muscle, reducing urinary urgency and frequency.
Ophthalmological Applications
- Atropine is used for cycloplegia and mydriasis in ophthalmology.
Central Nervous System Effects
- Atropine causes excitement, agitation, and hallucinations in the central nervous system.
FDA-Approved Indications
- Ipratropium is FDA-approved for rhinorrhea, common cold, and allergic/nonallergic rhinitis.
