|
Distribution.
|

|
|
|
What happens during Distribution?
|
In some cells, tissues and organs, Storage of the drug may occur; in others, Metabolism of the drug may occur.
|
|
|
Delivery of the drug to some organs may lead to Excretion of the drug. In order for its action to be terminated, a drug must either be
|
metabolized or excreted:
|
|
|
the sum of the processes of metabolism and of excretion is known as ?
