Key concepts, roles, and foundational principles for students and new professionals

1. What Is Pharmacy Practice?

2. Major Roles of the Pharmacist

3. Foundations of Pharmacy Practice

3.1. Pharmacology & Pharmacotherapy

• Pharmacodynamics – How drugs affect the body (receptor interaction, dose‑response).
• Pharmacokinetics – ADME: Absorption, Distribution, Metabolism, Excretion.
• Therapeutic classes – Antimicrobials, antihypertensives, CNS agents, etc.

3.2. Pharmaceutics

• Dosage‑form design (tablets, injectables, inhalers)
• Stability, compatibility, compounding techniques

3.3. Pharmacy Law & Ethics

• Key statutes (e.g., Controlled Substances Act, Food, Drug & Cosmetic Act)
• Professional standards – confidentiality (HIPAA), informed consent, duty of care
• Ethical frameworks – beneficence, non‑maleficence, autonomy, justice

3.4. Clinical Skills

• Medication History – Allergies, current meds, comorbidities
• Therapeutic Drug Monitoring (TDM) – Interpreting serum levels, dose adjustments
• Patient Assessment – Vital signs, lab values, symptom evaluation
• Documentation – SOAP notes, electronic health records (EHR)

4. Workflow in a Typical Pharmacy

1. Prescription receipt – electronic, fax, or handwritten.
2. Verification – check for completeness, appropriateness, interactions, allergies.
3. Preparation – dispense, compound, label.
4. Counseling – provide medication guide, answer questions, reinforce adherence.
5. Documentation & Follow‑up – record interventions, schedule MTM if needed.
6. Quality & Safety Checks – barcode verification, double‑check high‑risk meds.

Visual tip: Use a flowchart on the wall to remind staff of each step and the “pause points” for safety.

5. Collaborative Practice & Interprofessional Care

• Collaborative Practice Agreements (CPAs) allow pharmacists to initiate, modify, or discontinue therapy under defined protocols.
• Team-based care models (e.g., patient‑centered medical
