Study Notes
Intravenous (IV) Bolus Injection
- Involves administering a single dose of a drug through a vein, resulting in a rapid increase in plasma concentration
Pharmacokinetic Equations
- Single and multiple doses of IV bolus can be used to determine:
- Peak plasma concentration (Cmax)
- Time to reach peak plasma concentration (Tmax)
- Area under the plasma concentration-time curve (AUC)
- Elimination half-life (t1/2)
- Clearance (CL)
- Volume of distribution (Vd)
Plasma Concentration-Time Curves
- After single and multiple IV bolus drug administration, plasma concentration-time curves can differentiate between:
- Absorption phase
- Distribution phase
- Elimination phase
- Steady-state concentration
- Accumulation of the drug
Elimination Half-Life
- Determination of elimination half-life (t1/2) involves calculating the time taken for the plasma concentration to decrease by half
Primary Outcome of IV Bolus Injection
- The primary outcome of an IV bolus injection is a rapid increase in plasma concentration, achieving therapeutic levels quickly
