Actions and Uses of Medicines

The Principles and Practice for Pharmacy Technicians module forms the core of the Open Awards Level 3 Technical Occupational Entry Diploma. It covers the legal, ethical, and professional frameworks that underpin the safe and effective practice of pharmacy technicians in community, hospital, and primary care settings. You will explore the role of the pharmacy technician within the healthcare team, the importance of accurate dispensing, and the management of medicines supply chains. This module also introduces key concepts such as patient confidentiality, consent, and the classification of medicines under the Human Medicines Regulations 2012.

Mastering this topic is essential because pharmacy technicians are increasingly taking on extended roles, including accuracy checking, medicines reconciliation, and providing public health advice. The module ensures you understand your professional accountability, the limits of your competence, and how to work within standard operating procedures (SOPs). It also prepares you for the mandatory registration with the General Pharmaceutical Council (GPhC) by embedding the standards for pharmacy professionals into everyday practice.

Within the wider qualification, this module links directly to the practical skills units on dispensing, aseptic techniques, and clinical services. It provides the theoretical foundation for understanding why procedures exist and how to apply them safely. By the end of this module, you should be able to demonstrate a systematic understanding of the legal and ethical responsibilities of a pharmacy technician, and be ready to apply this knowledge in supervised practice.

• →Legal classification of medicines: Understand the differences between General Sale List (GSL), Pharmacy (P), and Prescription-Only Medicines (POM), and the legal requirements for supplying each.
• →Standard Operating Procedures (SOPs): Know that SOPs are mandatory, legally required documents that must be followed exactly to ensure consistency and safety in all pharmacy activities.
• →Patient confidentiality and consent: Apply the principles of the Data Protection Act 2018 and GDPR, and understand when and how to obtain valid consent for services.
• →Professional accountability: Recognise that pharmacy technicians are registered professionals accountable to the GPhC, and must work within their competence and scope of practice.
• →Medicines supply chain: Understand the processes for ordering, receiving, storing, and disposing of medicines, including controlled drugs and temperature-sensitive products.

• Award credit for accurately describing the mechanism of action of a named medicine, including relevant receptor or enzyme targets.
• Credit for correctly using the BNF (or equivalent up-to-date resource) to identify licensed indications, common doses, and key cautions for a given drug.
• Evidence of understanding limitations is shown by identifying at least two contraindications or significant drug interactions for a specified medicine.
• In answering a pharmaceutical query, credit must be given for selecting the most appropriate reference source, citing the specific section, and interpreting the information correctly.

• 💡Always structure your answers by linking the drug’s action to its therapeutic use and then highlighting limitations—this demonstrates integrated understanding.
• 💡Familiarize yourself with the layout of the BNF and electronic Medicines Compendium; in assessments, time spent searching efficiently can save marks.
• 💡When faced with a pharmaceutical query, explicitly state which resource you would consult and why, even if you then summarise the answer from memory.
• 💡Practice applying your knowledge to case studies, considering patient-specific factors like age, pregnancy, and comorbidities that influence medicine choice.
• 💡Always refer to current legislation by name and year (e.g., Human Medicines Regulations 2012, Misuse of Drugs Regulations 2001) to show depth of knowledge. Examiners reward precise legal references.
• 💡When answering questions about professional practice, explicitly link your answer to the GPhC standards for pharmacy professionals, especially the standards on confidentiality, competence, and honesty.
• 💡Use real-world examples from community or hospital pharmacy to illustrate your points. For instance, explain how you would handle a discrepancy in a controlled drug balance, linking it to SOPs and legal requirements.

• Confusing the actions of drugs from the same class but with different primary indications (e.g., beta-blockers for hypertension vs. angina).
• Misinterpreting BNF entries, such as assuming all listed doses apply to every patient without considering renal/hepatic function.
• Overlooking common side effects that may significantly impact adherence, like sedation with antihistamines.
• Failing to differentiate between the pharmacological action and the clinical use when answering questions.
• Misconception: Pharmacy technicians can legally prescribe or change a prescription. Correction: Only pharmacists and other qualified prescribers can prescribe; technicians can only supply against a valid prescription under a PGD or patient-specific direction.
• Misconception: SOPs are just guidelines that can be adapted as needed. Correction: SOPs are mandatory legal documents; any deviation must be authorised and documented, otherwise it is a breach of professional standards.
• Misconception: Confidentiality means never sharing any patient information. Correction: Information can be shared with other healthcare professionals involved in the patient's care, or when required by law (e.g., safeguarding), but only the minimum necessary.
