    Study Notes

    Prescription Overview

    • A prescription is a written directive from a licensed medical practitioner for a pharmacist to prepare and dispense medication.
    • It includes instructions for drug preparation and dosage for the patient.
    • Commonly written in English, prescriptions often incorporate Latin terms and abbreviations.

    Key Parts of a Prescription

    • Date: Indicates when the prescription was written; crucial for scheduling refills, especially for narcotics.
    • Patient Information: Must include name, age, sex, and address to identify the recipient and assist in dosage calculations for children.
    • Superscription (Rx): The symbol "Rx" means "you take," historically linked to requests for recovery.
    • Inscription: Lists names and quantities of ingredients, including:
      • Base: Active medication for therapeutic effect.
      • Adjuvant: Enhances effectiveness or taste.
      • Vehicle: Helps dissolve solids or increase volume.
    • Subscription: Directions to the pharmacist about preparing the medication and the number of doses to dispense.
    • Signa (Sig): Instructions for the patient on how to use the medication, including dosage quantity, frequency, route, and special instructions.
    • Renewal Instructions: Indicates whether prescription refills are permitted and how many times.
    • Prescriber Details: Must include the prescriber’s signature, address, and registration number to prevent misuse.

    Handling Prescriptions

    • Receiving: Pharmacists should personally receive prescriptions without displaying confusion or surprise.
    • Reading and Checking: Verify prescription format and consult if there are any doubts about ingredients or directions.
    • Collecting and Weighing: Gather all materials needed and double-check measurements to avoid errors.
    • Compounding, Labeling, and Packaging: Conduct in a clean area with proper labeling and quality materials.

    Modern Prescribing Practices

    • Majority of drugs are available as ready-made formulations, prescribed by official rather than proprietary names.
    • Advantages of using proprietary names include better patient recall and communication.
    • Disadvantages include potential prescription difficulties due to variations in formulations affecting bioavailability.

    Care Required in Dispensing

    • Keep the prescription visible while retrieving medications to minimize mistakes.
    • Ensure scales and dispensing equipment are clean and properly managed.
    • Use correct labeling, especially for external medications.

    Common Sources of Error in Prescriptions

    • Abbreviations: Care in interpretation is crucial to avoid misdispensing.
    • Drug Names: Similar-sounding or looking drug names can lead to mistakes (e.g., Digitoxin vs. Digoxin).
    • Strength of Preparation: Must be specified to avoid confusion with available forms.
    • Dosage Forms: Different forms can lead to errors if not properly indicated.
    • Dosages: Carefully evaluate unusually high or low doses and consult pediatric guidelines when necessary.
    • Patient Instructions: Incomplete or omitted guidelines can cause misuse or misunderstanding.
    • Incompatibilities: Check for pharmaceutical or therapeutic interactions between prescribed drugs.

    • Capsula: Capsule
    • Cataplasma: Poultice
    • Charta: Powder
    • Collutorium: Mouthwash
