Study Notes
Cholinergic and Anticholinergic Drugs Overview
- Cholinergic drugs primarily enhance the actions of acetylcholine, impacting various body systems.
- Anticholinergic drugs inhibit acetylcholine's effects to reduce bodily secretions and muscle contractions.
Adverse Effects
- A potential adverse effect of anticholinergic drugs includes dry mouth, constipation, blurred vision, and urinary retention.
- Patients taking anticholinergic drugs should contact their doctor if experiencing severe side effects like confusion, hallucinations, or signs of an allergic reaction.
Antidotes and Interactions
- The antidote for anticholinergic drug toxicity is typically Physostigmine.
- Atropine, a common anticholinergic, is used to treat bradycardia and to reduce salivary and bronchial secretions during surgery.
- Glycopyrrolate/Robinul is administered preoperatively to decrease secretions.
Effects on Body Systems
- Anticholinergic drugs increase heart rate by blocking the vagus nerve’s influence on the heart.
- They can worsen conditions such as glaucoma due to increased intraocular pressure.
Contraindications and Conditions Treated
- Contraindications for anticholinergic drugs include glaucoma, myasthenia gravis, and certain urinary retention issues.
- Anticholinergic medications, including Dicyclomine/Bentyl, are used for functional bowel syndrome and related gastrointestinal issues.
- Scopolamine is often used to prevent motion sickness.
Risks and Considerations
- A potential risk for patients on anticholinergic drugs includes increased risk of dementia with long-term use.
- Anticholinergic drugs may lead to urinary retention by causing contraction of the internal sphincter.
Therapeutic Uses
- Anticholinergics are useful for treating conditions such as overactive bladder, chronic obstructive pulmonary disease (COPD), and preoperative sedation.
- They dry out secretions and are frequently used in surgical settings to facilitate procedures.
