Clinical Pharmacology

Dicloxacillin sodium, USP is resistant to destruction by acid. Absorption of dicloxacillin sodium after oral administration is rapid but incomplete. Food in the gastrointestinal tract decreases the absorption of dicloxacillin. Studies with an oral dose of 125 mg gave average serum levels at 60 minutes of 4.74 mcg/mL. At four hours, average levels were 0.62 mcg/mL. In one study, single oral doses of dicloxacillin sodium 500 mg produced peak serum concentrations of 10 to 17 mcg/mL at 1 to 1.5 hours.

Once absorbed, dicloxacillin sodium is 95% to 99% bound to serum proteins, mainly albumin.

Dicloxacillin sodium, with normal doses, has insignificant concentrations in the cerebrospinal and ascitic fluids. It is found in therapeutic concentrations in the pleural, bile, and amniotic fluids. Dicloxacillin sodium is rapidly excreted as unchanged drug in the urine by glomerular filtration and active tubular secretion. The elimination half-life for dicloxacillin sodium is about 0.7 hours.

Dicloxacillin is not dialyzable. Only minimal amounts are removed by hemodialysis or peritoneal dialysis.[1]
