Key Pharmacology Concepts for PN Practice

Building a strong foundation in pharmacology requires understanding several core concepts:

• Pharmacokinetics: This branch of pharmacology describes what the body does to the drug. It encompasses four key processes:
  • Absorption: How the drug enters the bloodstream from the site of administration. Factors influencing absorption include route of administration, drug formulation, and patient-specific characteristics.
  • Distribution: How the drug travels throughout the body to reach its target site. Factors influencing distribution include blood flow, tissue permeability, and protein binding.
  • Metabolism: How the drug is broken down or transformed by the body, primarily in the liver. Metabolism can alter the drug's activity and allow its elimination.
  • Excretion: How the drug is eliminated from the body, primarily through the kidneys. Other routes of excretion include the bile, feces, and lungs.
• Pharmacodynamics: This branch of pharmacology describes what the drug does to the body. It involves understanding how drugs interact with receptors, enzymes, and other cellular targets to produce their therapeutic effects. Key concepts include:
  • Mechanism of Action: The specific way a drug interacts with its target to produce a pharmacological effect.
  • Therapeutic Effect: The desired or intended effect of the drug.
  • Adverse Effects: Undesirable or unintended effects of the drug.
  • Drug Interactions: The effects that occur when two or more drugs are taken together.
