How Do You Calculate Percent Half Life? Understanding the concept of half-life is useful for determining excretion rates as well as steady-state concentrations for any specific drug. Different drugs have different half-lives; however, they all follow this rule: after one half-life has passed, 50% of the initial drug amount is removed from the body. What
What Is Meant By Pharmacokinetics And Pharmacodynamics? In simple words, pharmacokinetics is ‘what the body does to the drug’. Pharmacodynamics describes the intensity of a drug effect in relation to its concentration in a body fluid, usually at the site of drug action. It can be simplified to ‘what the drug does to the body’.
What Is The MEC Of A Drug? Minimum effective concentration (MEC) is the minimum plasma concentration of a drug needed to achieve sufficient drug concentration at the receptors to produce the desired pharmacologic response, if drug molecules in plasma are in equilibrium with drug molecules in the various tissues (Figure 1.3). How do I get
