About Drug Half-Life
Drug half-life (t½) is the time required for the concentration of a drug to decrease by 50%. It's crucial for determining dosing intervals, time to steady state, and drug elimination.
Half-Life Results
Important Information
- Elimination Half-Life: Time for drug concentration to decrease by 50% during elimination phase
- Distribution Half-Life: Time for drug to distribute from plasma to tissues
- Terminal Half-Life: Final elimination phase half-life
- Effective Half-Life: Apparent half-life considering all elimination processes
- Steady State: Reached after 4-5 half-lives of consistent dosing
- Dosing Interval: Typically 1-2 half-lives for most drugs
