    Study Notes

    Ibuprofen

    • Classified as a nonsteroidal anti-inflammatory drug (NSAID).
    • Onset of action typically occurs within 30 to 60 minutes after administration.
    • Acts primarily by inhibiting cyclooxygenase (COX) enzymes, which decreases prostaglandin production.
    • Patients with pre-existing renal impairment or dehydration are at highest risk for renal impairment due to ibuprofen usage.
    • Older adults may require careful monitoring due to higher risks of gastrointestinal bleeding and renal issues when taking ibuprofen.

    Controlled Substances

    • Schedule III drugs, such as codeine and morphine, are used for pain relief but have potential for abuse.
    • Drugs classified under Schedule IV have accepted medical use but also potential for abuse.
    • Nursing responsibilities include ensuring proper documentation, security, and accurate patient education regarding controlled substances.

    Pharmacokinetics

    • Main pharmacokinetic process for drug absorption involves passive diffusion across biological membranes.
    • Serum drug levels are measured to ensure efficacy while preventing toxicity.

    Acetaminophen (Tylenol)

    • Acetaminophen is classified as an analgesic and antipyretic medication.
    • Generic name is paracetamol in many regions.
    • Primarily metabolized by the liver; caution is required in patients with liver disease.
    • Most effective antidote for acetaminophen overdose is N-acetylcysteine.
    • Use with caution in patients with existing liver conditions, alcohol use disorder, or in those taking other hepatotoxic drugs.

    Warfarin

    • Main mechanism of action involves inhibiting Vitamin K-dependent clotting factor synthesis in the liver.
    • Primarily excreted through the liver; renal impairment can affect its excretion and dosage.
    • Vitamin K is essential for the synthesis of clotting factors affected by warfarin therapy.

    Methotrexate and Pediatric Considerations

    • Methotrexate is a folate antagonist used for certain cancers and autoimmune diseases in children.
    • It carries a teratogenic risk and should be avoided in pregnant females or those planning pregnancy.
    • Common adverse effects include myelosuppression and gastrointestinal toxicity.

    Amoxicillin-Clavulanate (Augmentin)

    • Use in patients with hepatic injury may lead to increased risk of liver enzyme elevations.
    • Common contraindications include a history of allergies to penicillin or cephalosporins.

    Aspirin and Pediatric Use

    • Aspirin is contraindicated in children due to the risk of Reye's syndrome, particularly following viral infections.
    • Therapeutic effects include anti-inflammatory, analgesic, and antipyretic properties.
    • Recommended dosage range for children is typically based on weight for fever and pain management.

    Clopidogrel

    • Effective as an antiplatelet agent, but children can experience uncommon adverse effects.
    • Maximum loading dose recommended for older patients is often lower due to increased bleeding risk.
    • Caution is necessary with hepatic impairment due to altered drug metabolism and increased bleeding risk.

    General Considerations

    • Dosing discrepancies can occur based on factors such as age, weight, and organ function (e.g., renal).
    • Careful consideration of drug interactions, contraindications, and patient-specific factors is crucial in medication administration and monitoring.
