Drug Action and Therapeutic Foundations

Build the scientific and patient-care framework used throughout the rest of pharmacy.

01

Relate drug targets, exposure, and response.

02

Recognize how dosage form and route change medication use.

03

Identify the information required for a safe medication assessment.

04

Communicate a defensible plan through counseling and documentation.

01.01

Drug Action, Exposure, and Response

Therapeutic decisions begin by connecting a drug target to the concentration that reaches it and the response that follows.

What to learn
  • Receptors, enzymes, transporters, and ion channels
  • Absorption, distribution, metabolism, and excretion
  • Potency, efficacy, therapeutic window, and dose response
  • Bioavailability, clearance, volume of distribution, and half-life
01.02

Formulations, Routes, and Calculations

A drug product is an engineered delivery system. Route, dosage form, release design, concentration, and measurement all affect safe use.

What to learn
  • Route versus dosage form
  • Immediate, delayed, and extended release
  • Concentrations, ratios, dilutions, and reconstitution
  • Flow rates, isotonicity, pH, and buffers

01.03

Interactions, Labs, and Monitoring

Medication safety depends on recognizing what can change exposure or response and choosing measurements that reveal benefit or harm.

What to learn
  • Pharmacodynamic and pharmacokinetic interactions
  • CYP inhibition, induction, and transporters
  • Baseline, efficacy, and toxicity monitoring
  • Renal, hepatic, hematologic, and electrolyte data
01.04

Patient-Care Workflow

Medication histories, reconciliation, assessment, counseling, documentation, and order verification turn scientific knowledge into care.

What to learn
  • Medication history and reconciliation
  • Prescription and order verification
  • SOAP notes and case presentation
  • Adherence, teach-back, transitions, and social drivers
01.05

Evidence, Pharmacogenomics, and Safety

Evidence becomes useful when study results, patient factors, genetic variation, and medication-system risks are interpreted together.

What to learn
  • Risk measures and confidence intervals
  • Genotype, phenotype, and metabolizer status
  • Clinical validity and actionability
  • Medication errors, adverse reactions, and quality improvement
