Factors Affecting Drug Responses

  • Genetic Make-Up

    • Influences drug metabolism; variability can cause toxicity.
  • Age

    • Decreased organ function with aging affects drug handling and efficacy.
  • Body Size/Weight

    • Larger individuals require higher drug doses for similar effects compared to smaller individuals.
  • Use of Other Drugs and Dietary Supplements

    • Some supplements can enhance or inhibit medication effects; combinations may cause life-threatening interactions.
  • Consumption of Food and Beverages

    • Foods can delay or inhibit drug absorption; alcohol may exacerbate CNS depressant effects.
  • Presence of Diseases

    • Conditions like kidney or liver disease can impair drug excretion or metabolism.
  • Drug Storage

    • Improper storage can affect drug efficacy.

Drug Approval Phases

  • Phase I: Safety and profile assessment in 20-80 healthy volunteers; ~1 year duration.
  • Phase II: Effectiveness evaluation with 100-300 patient volunteers; ~2 years duration.
  • Phase III: Extensive monitoring in 1000-3000 patients; takes about 3 years.
  • Final FDA approval process can take approximately 2.5 years post-trials.

Pregnancy Categories (Established 1979)

  • Category A: No risk shown in well-controlled studies; considered safe (e.g., Levothyroxine, Folic Acid).
  • Category B: No adverse effects in animals, but no studies in humans (e.g., Metformin, Amlodipine).
  • Category C: Adverse effects in animals; potential benefits may justify use in pregnancy (e.g., Tramadol).
  • Category D: Adverse effects in humans, but benefits may outweigh risks (e.g., Losartan).
  • Category X: Risks clearly outweigh benefits; can cause teratogenic effects (e.g., Atorvastatin).

New Labelling System
