Study Notes
Adrenergic Drugs: Sympathetic Superpowers
- Mimic the Sympathetic Nervous System (SNS)
- Epinephrine: Opens bronchi, increases blood pressure (e.g., anaphylaxis)
- Dopamine: Enhances cardiac output (e.g., shock management)
- Key Receptors:
- Beta2-Adrenergic: Bronchodilation (e.g., asthma)
- Beta1-Adrenergic: Heart rate and strength of contractions
- Patient Teaching:
- Do not abruptly stop beta-blockers (e.g., Atenolol)
- Monitor pulse and blood pressure regularly
- Be aware of hypoglycemia symptoms when using beta-blockers
Anticholinergic Drugs: PNS Blockers
- Block the Parasympathetic Nervous System (PNS)
- Reduce secretions, slow systems
- Glycopyrrolate: Used pre-surgery to reduce oral and GI secretions.
- Oxybutynin: Decreases urinary frequency, helps with bladder control.
- Watch for:
- Dry mouth
- Blurred vision
- Constipation
- Special Notes for Active Seniors: Stay cool to prevent heat stroke due to reduced sweating.
Cholinergic Drugs: Boosting Acetylcholine
- Stimulate the PNS by increasing acetylcholine levels
- Donepezil: Improves memory in Alzheimer's patients (not a cure)
Disease-Specific Drug Applications
- Heart Conditions: Carvedilol treats mild heart failure. Watch for worsening heart failure symptoms (edema, shortness of breath).
- Respiratory Management: Albuterol helps during acute asthma attacks (tachycardia possible). Salmeterol prevents, but does not treat, sudden asthma symptoms.
- Neurological Focus: Memantine manages symptoms of Alzheimer's Disease. Pyridostigmine improves swallowing in Myasthenia Gravis (take 30 minutes before meals).
Clinical Scenarios
- Phentolamine: Prevents tissue damage from vasopressors (e.g., dobutamine).
- Physostigmine: Antidote for atropine overdose.
Patient Education Essentials
- Safety Precautions: Notify a doctor if pulse drops below 60 bpm while on beta-blockers. Avoid overheating if taking anticholinergics, stay hydrated.
- Timing Is Everything: Apply Scopolamine Patch 4-5 hours before travel, schedule cholinergic drugs carefully with meals
- Herbal Awareness: Ginkgo biloba increases bleeding risk when combined with aspirin.
