    Study Notes

    Orphan Drugs

    • Drugs that are discovered but lack financial viability for adoption by pharmaceutical companies.
    • Potentially beneficial for treating rare diseases but may cause severe adverse effects.
    • Often abandoned after preclinical trials or phase I studies due to:
      • Lack of therapeutic activity
      • High toxicity
      • Teratogenic effects
      • Small margin of safety
    • Examples include Zavesca (miglustat), Trisenox (arsenic trioxide), Aldurazyme (Laronidase), and Glivec (Imatinib mesylate).

    Drug Forms

    • Capsules

      • Enteric-coated, chewable, sustained release, soft gel, and hard gel types.
    • Liquid Forms

      • Syrup, suspension, elixir, emulsion, inhalants.
    • Topical Forms

      • Cream, ointment, lotion, gel, patch, and suppository.

    Injection Routes

    • Intra-articular: Injected into a joint.
    • Intrathecal: Injected into the spinal canal.

    Principles of Drug Administration

    • Medications are substances for diagnosing, treating, or preventing diseases.
    • RN responsibilities include questioning unclear orders, knowing medication information, and proper patient identification.

    Routes of Administration

    • Buccal, Sublingual, and Translingual: Administered to prevent degradation in the gastrointestinal tract.
    • Gastric: Directly delivers drugs into the GI system via tubes for patients unable to swallow.
    • Oral: Preferred route due to safety, convenience, and cost, used for conscious patients.
    • Topical: Applied through skin or mucous membranes for dermatologic or local effects.
    • Rectal/Vaginal: Suppositories or creams can treat local infections while allowing for potential systemic absorption.
    • Respiratory: Gases can be inhaled for rapid absorption.

    Ten Rights of Medication Administration

    • Right Client: Verification through ID bands and verbal confirmation.
    • Right Drug: Ensuring correct medication is given.
    • Right Dose: Accurate dosage as per order.
    • Right Time: Administering at recommended intervals.
    • Right Route: Correct administration method for effective absorption.
    • Right Evaluation: Monitoring the patient's response to the medication.
    • Right to Refuse: Patients can decline medication; nurses must facilitate compliance when possible.

    Oral Medications

    • Most common route; contraindications include:
      • Vomiting or unconscious patients
      • Intestinal or gastric suction patients
      • Difficulty swallowing
    • Tablets/capsules may be crushed (except enteric-coated and certain types) and mixed with water for easier administration.

    Parenteral Medications

    • Administered via injection methods, such as intradermal or intramuscular; requires precise site selection and technique.
