Drug antagonism takes place when one particular drug's exercise is countered by An additional drug's action on exactly the same pharmacological technique.
Values for that dose-reaction curve really should for that reason be established within the (averaged) responses to solitary drug administrations calculated in different subjects. Even calculated this way, a dose-response curve can only serve a person legitimate objective: it demonstrates the typical romance concerning the dose as well as the Original

Age: Age is A vital factor in deciding the right dosage of a medication. Youthful kids and elderly sufferers may have to have reduce doses than Grownups on account of variations inside their metabolism.
This is often demonstrated in simulations While using the mathematical model revealed in Fig. six, where the dose plus the drug effect are plotted individually versus time For instance the impact of tolerance improvement on dose-reaction curve measurements.
