Drug Elimination

Drug elimination is a process which involves irreversible removal of drug from the body from all routes of elimination. Drugs are eliminated from the body by various elimination processes and usually categorized into two major components: excretion and biotransformation. The declining plasma drug concentration which is observed after systemic drug absorption shows that the drug is eliminated from the body but it does not indicates the process involved in elimination.
