Pharmacokinetics

Pharmacokinetics: single dose

No items found.

Learn how to calculate the key pharmacokinetic properties of a drug and understand the importance of each in relation to drug dose and plasma concentration.

Learning outcomes

  • Calculate the bioavailability and volume of distribution of pharmaceutical drugs in different contexts.
  • Determine half-lives and elimination constants for a variety of pharmaceutical drugs.
  • Identify when steady state is reached and how to calculate it.
  • Design graphs to enable estimation and calculation of pharmacological half-lives.

Skills

Concepts, Principles and Theories

  • What is meant by absorption and bioavailability 
  • What is the volume of distribution 
  • What factors contribute to the elimination of a drug from the body 
  • What is the difference between zero order and first order elimination kinetics 
  • What is meant by the elimination half-life, elimination constant and total clearance 
  • What is meant by the steady state and therapeutic window 

Manipulating and Presenting Data

  • How to calculate the bioavailability when the IV and non-IV dose are the same and when the doses are different 
  • How to calculate the volume of distribution and total clearance
  • How to calculate steady state for a single dose and multiple doses
  • How to calculate the dose interval for a dosage regimen 
  • How to calculate the loading dose and maintenance dose
  • How to graphically estimate the initial plasma concentration and rate

Interpreting and Analysing Data

  • How to estimate the volume of distribution from a graph
  • How to calculate steady-state concentration
  • How to analyse graphs to estimate the drug's half-life
  • How to analyse a graph's trendline to calculate pharmacokinetic parameters

"The great thing about Smart Worksheets is that they tell you at every point whether you’ve got it right or wrong, what might be wrong and how you might go about changing it. The students found that really valuable. In their exam, we found that the average mark in the maths questions rose from 59% to 79%, which made a really big difference to the student outcome.”
