Ensuring delivery of the most efficacious dose
Drug administration route is often classified by the location at which the drug is administered, such as oral or intravenous. The choice of routes in which the medication is given depends not only on convenience and compliance but also on the drug’s pharmacokinetics and pharmacodynamic profile. Therefore it is crucial to understand the characteristics of the various routes and associated techniques as the first step before PK/PD, efficacy/pharmacology and toxicity study.
