Study Notes
- Anticholinergic medications, also known as cholinergic antagonists or cholinergic blockers, work by opposing the effects of cholinergic agonists.
- Anticholinergics inhibit acetylcholine action, leading to increased heart rate, bronchodilation, and decreased secretions.
- Anticholinergics also decrease motility and peristalsis, reduce GI secretions, increase bladder sphincter constriction, and dilate pupils.
- They can also reduce salivation, perspiration, tremors, and rigidity.
Atropine
- Atropine is a non-selective anticholinergic medication
- Atropine functions by inhibiting acetylcholine through occupying receptors, which increases heart rate by blocking vagal nerve stimulation.
- Atropine Uses:
- To reduce salivation, respiratory, and GI secretions before surgery.
- To increase heart rate in cases of bradycardia.
- To dilate pupils for eye exams.
- Atropine Adverse Reactions:
- Dry mouth and skin
- Inability to sweat
- Flushing, blurred vision
- Constipation
- Urinary retention
- Palpitations
- Hypertension
- Atropine Contraindications:
- Glaucoma
- GI disorders that slow the GI tract
- Tachycardia
- Benign Prostatic Hypertrophy
- Myasthenia Gravis
- Atropine Interactions:
- Antihistamines can increase anticholinergic effects.
Benztropine
- Benztropine is an anticholinergic and antiparkinson medication that blocks acetylcholine to skeletal muscles.
- It also blocks dopamine reuptake which allows domaine to work for a longer amount of time.
- Benztropine Uses
- Decreases involuntary muscle movement, tremors, and muscle rigidity
- Treats Parkinson’s disease and pseudoparkinsonism.
- Benztropine Adverse Reactions:
- Reactions are very similar to atropine.
- Benztropine Contraindications:
- Glaucoma
- Tardive dyskinesia
- Myasthenia gravis
- Caution with psychosis.
- Benztropine Interactions:
- It interacts with other anticholinergic drugs, as well as drugs that increase heart rate and blood pressure.
Tolterodine Tartrate
- Tolterodine Tartrate is an anticholinergic medication
- It selectively blocks cholinergic receptors in the bladder to treat overactive bladder.
- Tolterodine then decreases urinary frequency, urgency, and incontinence.
- Tolterodine Tartrate Adverse Reactions:
- Reactions are similar to atropine.
- Tolterodine Tartrate Contraindications:
- Contraindications are similar to atropine
- Tolterodine Tartrate Interactions:
- Grapefruit juice can increase drug levels.
Anticholinergic Drugs: Nursing Considerations
- Assessment:
- Assess vital signs
- Medication/medical history
- What is the reason it's being given?
- Urine output
- Interventions:
- Monitor vital signs and report tachycardia
- Monitor I & O for urinary retention
- Monitor bowel status for constipation
- Provide mouth care
- When administering atropine IV, dilute in sterile water and administer slowly at a rate of at least 1 mg/minute
Client Teaching
- Avoid hot environments
- Increase fluid intake and fiber
- Report large decrease in urine output
- Use hard candy for dry mouth
- Practice good oral care
- Wear sunglasses in bright light
- Avoid driving if drowsiness occurs
Evaluation
- Evaluation checks if the drug has had a therapeutic effect
- Atropine effectiveness is based on the heart rate increasing if the client had bradycardia.
- The effectiveness of benztropine is based on decreased involuntary movement.
- Tolteradine Tartrate effectiveness is based on decreased bladder irritability, fewer trips to the bathroom, and balanced I & O.
- For pre surgery patients, effectiveness will be based on the client reporting a decrease in dry mouth.
