dose regimen of the same drug IV and oral

[ykw]

I have been having this question in mind for quite some time: IV medication enters the blood directly, but why are some of them being given a higher dose than their oral counterparts? Some are even given more frequent than the oral ones eg. oral cefuroxime and IV cefuroxime.

Go to original manufacturers web site and dosage info etc should be there.

Reason depends on a number of things such as indication, age of the patient, concurrent hepatic/renal impairment etc.

Partly because IV administration is normally reserved for severe acute illness, which may require high doses.
