Study Notes
Module I
- Pharmacodynamics: Study of how drugs affect the body
- Key points for how drugs work:
- Replacing missing chemicals
- Increasing or stimulating cellular activities
- Depressing or slowing cellular activities
- Interfering with foreign cell function
- Pharmacokinetics: Study of how the body acts on a drug
- Key points for pharmacokinetics:
- Absorption: Drug movement to circulating fluids
- Distribution: Drug movement in tissues
- Metabolism (biotransformation): Drugs transformed into less active chemicals, liver is most important
- Excretion: Removal of drugs from the body, kidneys are most important
- First-pass effect: Drug metabolized by liver before entering circulation
- Adverse effects:
- Anaphylaxis: Rapid, severe allergic reaction
- Hepatotoxicity: Liver damage
- Nephrotoxicity: Kidney damage
Adverse Effects
- Anaphylaxis: Rapid, severe, potentially life-threatening allergic reaction. Occurs within minutes of re-exposure to allergen. Commonly triggered by bee stings, peanuts, shellfish and some food types. Can lead to shock and death.
- Hepatotoxicity: Liver damage. Symptoms include fever, malaise, nausea, jaundice, changes in stool, abdominal pain, and elevated liver enzymes.
- Nephrotoxicity: Kidney damage. Symptoms include elevated BUN and creatinine, decreased urinary output, and fatigue.
Neurological Effects
- General CNS effects: Include confusion, delirium, and insomnia. Safety measures to prevent injury, orient the patient, and provide proper support are important interventions.
- Extrapryramidal symptoms: Parkinson's-like symptoms, such as tremors, changes in gait, and rigidity. Discontinuing medication is a primary intervention.
- Anticholinergic effects: Dry mouth, urinary retention, blurred vision. Interventions include sugarless lozenges, mouth care, and bowel programs.
- Neuroleptic malignant syndrome: Emergency. Symptoms include neurological symptoms, hyperthermia, and autonomic disturbances. Discontinuing medication and reducing patient body temperature are key interventions.
Module II
-
Hydantoins (phenytoin), barbiturates (phenobarbital), valproic acid, dopaminergic (carbidopa-levodopa), opioid agonist (morphine), opioid antagonist (naloxone).
-
Pharmacokinetics (phenytoin): Metabolized by the liver, excreted by the kidneys. Oral (slow) and IV (rapid).
Module III
- Alpha-Beta adrenergic agonist (dopamine)
- Beta-specific adrenergic agonist (isoproterenol)
- Non-selective adrenergic blocking agent (labetalol)
- Non-selective Beta-adrenergic blockers (propranolol)
Module 5A
-
ACE inhibitors (captopril)
-
ARB's (losartan)
-
Calcium channel blockers (diltiazem)
-
Vasodilators (nitroprusside)
-
Cardiac glycosides (digoxin)
-
Drugs affecting the RAAS:
- ACE inhibitors
- ARBs (angiotensin II receptor blockers)
- Renin inhibitors
Module 5B
- Nitrates (nitroglycerin)
- Beta-adrenergic blocker (metoprolol)
- HMG-CoA reductase inhibitors (atorvastatin)
- Antiplatelet (ASA)
- Anticoagulant (Heparin)
- Thrombolytic agents (alteplase)
General Information
- The purpose of many of these medications is to help lower blood pressure, treat heart failure, or treat other systems of the body to get the body back to a balanced state.
- It is essential that patients are properly assessed, monitored and that their care plan is developed and followed so the patient does not have negative side effects.
Additional Modules
- Modules are not numbered and topics are not provided in the input.
