Study Notes
Clinical Cases File
- The Lippincott Pharmacology Textbook contains 175 clinical cases.
- The cases were collected and summarized by Hiba Alzoubi.
Principles of Drug Therapy
- An 18-year-old female patient overdosed on a drug. Intravenous administration of the antidote is the most desirable route.
- A 40-year-old male patient received 2000 mg of vancomycin. The apparent volume of distribution is approximately 1 L/kg.
- A 65-year-old female patient with stroke prevention was prescribed clopidogrel. Poor CYP2C19 metabolism is a likely reason for recurrent ischemic stroke.
PK Equations
- Single-Dose Equations: Volume of distribution (Vd)
- Multiple Doses or Infusion Rate Equations: Infusion rate (ko), Loading dose (LD), Maintenance dose (MD)
- Numerous formulas are included
Drugs Affecting the Autonomic Nervous System
- An elderly female ingested a liquid that may have been an organophosphate pesticide. Her symptoms were those of cholinergic crisis.
- The case featured a patient with dangerously high symptoms suggestive of cholinergic crisis (e.g., diarrhea, frequent urination, convulsions, breathing difficulties, constricted pupils, and excessive salivation.)
- The symptoms of the patient are consistent with cholinergic crisis which is commonly caused by organophosphates pesticides and are not consistent with sympathetic activation.
Cholinergic Agonists and Antagonists
- A patient accidentally administered a drug causing pupil dilation (mydriasis) instead of constriction. The most likely culprit was a cholinergic antagonist like atropine or ropicamide instead of a miotic like pilocarpine.
- A patient experiencing organophosphate poisoning (from organophosphate pesticides) will exhibit symptoms of cholinergic crisis.
- Treatment for cholinergic crisis requires anticholinesterase agents, not cholinergic agonists
Drugs Affecting the Respiratory System
- A patient with asthma who was prescribed a β2 agonist, but did not respond to the treatment, may require a muscarinic agonist as an alternative.
- A patient with chronic obstructive pulmonary disease (COPD) who does not respond to β2 agonists may benefit from a muscarinic agonist, like ipratropium (a SAMA; short-acting muscarinic antagonist).
Drugs Affecting the Central Nervous System
- An elderly man ingested carvedilol, a drug that blocks α1, β1, and β2 adrenergic receptors, causing symptoms that point to cholinergic crisis (e.g., reduced heart rate, bradycardia, etc.)
Clinical Toxicology
- A patient presents to the emergency room with elevated levels of blood alcohol (275mg/dL) after a bout of heavy drinking for three weeks. The appropriate treatment choice for seizures associated with alcohol withdrawal is benzodiazepines (e.g., lorazepam, diazepam).
- A patient who is suffering from a benzodiazepine overdose should receive flumazenil.
Drugs for Neurodegenerative Diseases
- Patients with levodopa therapy may experience adverse gastrointestinal and cardiovascular side effects that can be managed with carbidopa.
Drugs for Anxiety and Hypnosis
- A patient presenting with seizures secondary to alcohol withdrawal and an elevated blood alcohol level would benefit from benzodiazepines.
Drugs for Mood Disorders
- If a patient is experiencing mood changes (loss of interest, feelings of guilt, worthlessness, and hopelessness), the appropriate treatment would include antidepressant agents such as SSRIs, SNRIs, or TCAs (tricyclic antidepressants).
Drugs for Hypertension
- Patients with hypertension and asthma should be considered for a selective β1-blocker (e.g., metoprolol) to prevent exacerbating their asthma symptoms.
- Patients already taking a β-blocker who need a second-line treatment drug for hypertension should not use non-selective β-blockers. These can cause adverse effects.
Drugs for Anesthesia
- When a patient is experiencing difficulty breathing due to bronchospasm, an appropriate treatment would involve using a β2 agonist. These drugs cause bronchodilation.
- When considering anesthetic drugs and their possible interactions with certain patient conditions, it is important to consider the patient's overall health status, such as kidney conditions or allergies. An example case shows a patient with a history of hypertension and diabetes. Intravenous drugs like propofol should be used carefully.
Drugs of Abuse
- A patient with a history of substance abuse or opioid use is likely to have similar symptoms if there is a possible overdose.
Drugs for Obesities
- A 45-year-old woman with hypertension and uncontrolled diabetes should not use a weight loss drug that interacts with blood pressure. Orlistat is an option that does not affect blood pressure.
Other Drugs for Various Disorders
- Various conditions and drug treatments are included as outlined in the text provided.
