Parenterals: Routes Intravenous (IV)

Advantages:

• IV drugs provide rapid onset of action compared with other routes of
administration, and because drug absorption is not a factor, optimum
blood levels may be achieved with accuracy and immediacy not
possible by other routes.

• Because of the rapid dilution in the circulating blood and the general
insensitivity of the venous wall to pain, the IV route may be used to
administer irritating drugs.
