Study Notes
Herbal Supplement Use During Pregnancy
- Pregnant women should consult healthcare providers before using herbal supplements. This is because of uncertain safety profiles and potential harm to the pregnancy or interference with medications.
Hazards of Over-the-Counter (OTC) Drug Use
- OTC drug use can delay treatment for serious conditions by masking symptoms. It may only treat the symptoms but not the underlying cause of a disorder and may postpone effective treatment for chronic diseases.
Ginkgo Interactions
- Ginkgo interacts dangerously with antiplatelet drugs, increasing the risk of bleeding.
Ginger Precautions
- Ginger can lower blood glucose, so it should be used cautiously with antidiabetic medications.
Criteria for OTC Drug Approval
- The drug must be safe and effective for use without a prescription. It must have a low potential for misuse. The condition treated must be self-diagnosable and self-treatable. Labeling must enable safe use without medical supervision, and benefits must outweigh risks.
St. John’s Wort and SSRIs
- Combining St. John’s Wort with SSRIs can cause serotonin syndrome, with symptoms like agitation, confusion, rapid heart rate, high blood pressure, dilated pupils, muscle rigidity, and excessive sweating.
Adrenergic Drugs and the Nervous System
- Adrenergic drugs stimulate the sympathetic nervous system.
Beta2-Adrenergic Receptors
- Beta2-adrenergic receptors are located in the lungs, liver, and smooth muscles of blood vessels. Albuterol is a beta2-adrenergic drug
Therapeutic Effect of Adrenergic Agonists in Shock
- Adrenergic agonists increase blood pressure and improve blood flow to vital organs.
Major Uses of Epinephrine
- Epinephrine is used to treat anaphylaxis, severe asthma attacks, and cardiac arrest.
Salmeterol Education
- Salmeterol is a long-acting bronchodilator and should not be used as a rescue inhaler.
Major Drug Effects of Adrenergic Agonists
- The four major drug effects are an Increased heart rate, increased force of heart contractions, bronchodilation, and vasoconstriction.
Beta1-Adrenergic Receptors
- Beta1-adrenergic receptors are primarily found in the heart; an example of a beta1-adrenergic antagonist is metoprolol.
Metoprolol Education
- Educate patients about potential side effects of metoprolol, such as dizziness, fatigue, and low heart rate. Advise against abruptly stopping medication, as it could worsen heart conditions.
Purpose of Phentolamine
- Phentolamine reverses vasoconstriction from dobutamine extravasation, preventing tissue necrosis.
Beta-Blocker Adverse Effects
- Beta-blockers may cause erectile dysfunction in males, leading to noncompliance.
Patient Education for Low Heart Rate on Beta-Blockers
- Patients should contact their healthcare provider if their heart rate falls below 60 bpm, but they shouldn't stop the medication before consulting them.
Tamsulosin Uses
- Tamsulosin is mainly prescribed for BPH in males but can treat urinary retention in females.
Cholinergic Drugs and the Nervous System
- Cholinergic drugs stimulate the parasympathetic nervous system.
Donepezil Effects
- Donepezil improves cognitive function and delays Alzheimer’s symptoms.
SLUDGE Acronym
- SLUDGE stands for Salivation, Lacrimation, Urination, Defecation, Gastrointestinal distress, and Emesis (vomiting).
Cholinergic Drug Effects
- The desired effects of cholinergic drugs result from stimulating muscarinic receptors.
Cholinergic Overdose Antidote
- Atropine is the specific antidote for the effects of a cholinergic overdose.
Bethanechol Therapeutic Effects
- After administering bethanechol for post-op urinary retention, the patient should urinate within 60 minutes.
Oxybutynin Contraindications
- A major contraindication is glaucoma, especially narrow-angle glaucoma.
Anticholinergic Cautions for Elderly
- Caution elderly patients about anticholinergic side effects like confusion, dry mouth, constipation, and urinary retention.
Darifenacin Advantages
- Darifenacin selectively targets M3 muscarinic receptors, reducing side effects like dry mouth.
Anticholinergics for Parkinson’s
- These drugs reduce tremors and muscle rigidity by balancing dopamine and acetylcholine levels.
Scopolamine Patch and Alcohol
- Combining a scopolamine patch with alcohol can increase sedative effects, causing excessive drowsiness and impairment.
Dicyclomine Use
- Dicyclomine is prescribed for irritable bowel syndrome (IBS) to reduce abdominal cramping.
