Study Notes
Cholinergic Drugs Overview
- Cholinergic drugs can have toxic effects, leading to symptoms associated with overstimulation of the parasympathetic nervous system.
- SLUDGE acronym represents Salivation, Lacrimation, Urination, Diarrhea, Gastrointestinal distress, and Emesis, highlighting common symptoms of cholinergic toxicity.
Specific Cholinergic Drug Uses
- Pilocarpine is a cholinergic drug commonly used to treat excessively dry mouth (xerostomia).
- Atropine may be used as an antidote in cases of cholinergic toxicity.
Functions and Effects of Cholinergic Drugs
- Cholinergic drugs enhance the function of the neurotransmitter acetylcholine, promoting bodily functions related to the rest-and-digest response.
- They affect multiple systems, resulting in increased salivation, lacrimation, urination, digestive activity, and secretion of sweat.
Cardiovascular Effects
- Cholinergic drugs generally lead to a decrease in heart rate and may cause vasodilation, influencing blood pressure.
Bladder Mechanisms
- Oxybutynin is used to relax the bladder sphincter, facilitating bladder emptying.
Ginkgo Biloba Insights
- Ginkgo is primarily used to enhance cognitive function and circulation.
- It may interact with anticoagulants, antiplatelet drugs, and other medications affecting coagulation.
Other Relevant Drugs
- Physostigmine can act as an antidote for severe overdoses of tricyclic antidepressants, reversing anticholinergic effects.
- Acetylcholine analogs such as pilocarpine are utilized in the management of glaucoma and during intraocular surgeries.
Anesthesia Context
- Succinylcholine is a neuromuscular blocker employed in general anesthesia to induce muscle relaxation for surgical procedures.
Conclusion
- Understanding the diverse effects and applications of cholinergic drugs is crucial for effective medical treatment and management of associated symptoms.
