Study Notes
- Dosage form design involves creating safe, effective, and convenient medicines, combining active drug substances with inactive excipients to ensure predictable and reproducible therapeutic responses.
Significance and Basic Definitions
- Dosage form design is crucial for pharmacists to optimize therapeutic outcomes through appropriate selection based on patient factors like age and swallowing ability.
- It helps ensure drug stability and quality by understanding how chemical interactions, packaging, and environmental conditions affect medications.
- Compounding allows pharmacists to create customized dosage forms when commercial options do not meet specific patient needs.
- Comprehensive knowledge of dosage form design enables pharmacists to manage potential drug interactions based on both active and inactive pharmaceutical ingredients.
- Pharmacists use dosage form knowledge to select appropriate multisource drug products, understanding pharmaceutical equivalence, bioequivalence, and therapeutic equivalence.
- Finished pharmaceutical products consist of active pharmaceutical ingredients (APIs) and excipients, with excipients serving various functions such as stabilization and API release modification.
- A dosage form is the physical form in which a drug is delivered, ensuring safety, efficacy, and stability through a combination of APIs and excipients.
- Formulation science aims to establish a precise medicine composition and preparation method.
- Extemporaneous preparations are compounded by a pharmacist.
Manufacturing Medicines in Australia
- Medicines are typically administered as medicinal preparations manufactured by the pharmaceutical industry (TGA licensed) or compounded by pharmacists (exempt from TGA license).
- The manufacturing process must always ensure the safety and quality of the medicine.
- Pharmacists can dispense both licensed and unlicensed medicines.
Regulatory Aspects of Dispensed Medicines in Australia
- Licensed medicines are manufactured by the pharmaceutical industry under strict TGA regulations.
- These regulations include Good Manufacturing Practice (GMP) licenses with regular TGA audits.
- TGA-approved consumer medicine information (CMI) and product information (PI) documentation is available for scheduled medicines.
- Unlicensed medicines are compounded by pharmacists without a GMP license and possibly no TGA-approved CMI or PI.
- Unlicensed medicines require a prescriber's request.
- Unlicensed medicines requires pharmacists trained in compounding medicines.
- Unlicensed medicines must be "extemporaneous" preparations complying with default standards such as the PIC/S guide to good manufacturing practices and pharmacopeias.
- Labelling and consumer information should follow best pharmacy practice standards.
- The Australian Pharmacy Board publishes compounding guidelines, emphasizing dosage forms and formulations.
Authorities and Resources for Regulatory Guidelines on ​​Medicine Manufacturing
- The Therapeutic Goods Administration (TGA) is responsible for medicine market approval, manufacturer licensing (GMP), and auditing in Australia.
- TGA defines the "default standards" for compounding.
- The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) provides technical guidelines on product quality and safety for industrial pharmaceutical production.
- International regulatory agencies, including the TGA, FDA (USA), and EMA (Europe), follow ICH guidelines.
- The Pharmaceutical Inspection Co-operation Scheme (PIC/S) leads in harmonizing GMP standards and quality systems for medicinal product inspectorates.
- PIC/S publishes GMP audit guidelines followed in Australia.
- The Australian Pharmacy Board publishes compounding guidelines with conditions for pharmacists.
Types of Extemporaneous Preparations by Trained Pharmacists in Australia
- Trained pharmacists are legally authorized to compound extemporaneous preparations.
- Extemporaneous refers to specific circumstances requiring timely preparation of a medicine that is not immediately commercially available.
