Q
  • Terminology of Drug Action
A
  • Receptor: target of drug
  • Action and interaction of drugs in the body:
    • Combination of two drugs
      + Additive action-1+1=2
      + Antagonistic-works against
      + Synergistic-1+1=3 (potentiation)
  • Other actions of drugs
    • Tolerance-waning action over time
    • Addiction-pt is physically or psychologically in need of the drug
