The plasma level time curve is plotted after measured drug concentration in plasma of an animal at different time intervals. The concentrations of drug in each plasma sample are plotted on an ordinary graph paper against the corresponding time at which the plasma samples were collected. As the drug reaches in systemic circulation, plasma drug concentration will rise to a [...]
This article throws light upon the four main terms related to agonist-antagonist interactions. They are: 1. PKX 2. PAX 3. PD’x 4. PDX. Term # 1. PKX: This is an expression for affinity and is defined as negative logarithm of the molar concentration of a drug that elicits an effect representing x% of the maximal response the drug can produce.
