    Study Notes

    USP Overview

    • Established in 1820 to standardize medicine in the U.S., enhancing public health and safety.
    • Initially listed almost 563 drugs over 272 pages.
    • Aimed to achieve consistent quality and therapeutic merit in pharmaceuticals.

    National Formulary

    • Created as a compendium for pharmaceutical standards, first known as the National Formulary of Unofficial Preparations in 1888.
    • Renamed National Formulary in 1906 after the Pure Food and Drug Act was enacted.
    • Purchase of NF by USP in 1975 unified the two compendia, latest editions being USP 42nd and NF 37th.

    Monographs

    • A monograph defines the standards for the identity, strength, purity, and consistency of a drug substance.
    • Includes identification tests, assay methods, purity assessments, physicochemical quality measures, and storage requirements.
    • Crucial for ensuring correct packaging and labeling of pharmaceutical products.

    Dosage Forms

    • Defined as formulated preparations for administering drugs, consisting of active pharmaceutical ingredients (APIs) and additives.
    • Protects drug entities from environmental damage and provides an optimal means for drug delivery.
    • Types include solid dosage forms, which can be controlled-release or delayed-release for consistent absorption rates.

    Drug Delivery Systems

    • Methods to transport pharmaceutical compounds into the body efficiently.
    • Route of administration can be intravascular (e.g., intravenous) or extravascular.

    Goal Drug Characteristics

    • A theoretical drug ideally meeting treatment criteria: desired effects, preferred administration route, minimal dosage, optimal action duration, and no side effects.

    Drug Discovery Methods

    • Random or Untargeted Screening: Tests numerous compounds for biological activity without specific targets, though some compounds may be missed.
    • Bioassays: Differentiate effects and potency of test agents using cell cultures.
    • High-Throughput Screening: Evaluates up to 15,000 compounds weekly with multiple assays.
    • Molecular Modification: Involves chemical alterations of known compounds to improve efficacy or safety.

    Pre-Clinical Studies

    • Pre-formulation studies gather essential information on drug characteristics, aiming to develop an optimal delivery system.
    • Focus on physical and chemical properties including solubility, stability, and dissolution rates.
