Maximal plasma cefdinir concentration can be attained between 2-4 hours after an ingested dose. The bioavailability of cefdinir depends on the formulation used. The estimated bioavailability of cefdinir in the capsule form is approximately 16%-21%, depending on the dose. Absolute bioavailability after the administration of a suspension of cefdinir is 25%.. The Cmax of cefdinir is 1.60 μg/mL after a 300 mg dose with an AUC of 7.05. Cmax is 2.87 μg/mL after a 600 mg dose with an AUC of 11. A meal high in fat can reduce the absorption of cefdinir by up to 15%, however, this is not a cause for clinically significant changes, therefore cefdinir may be taken with or without food. When given with aluminum or magnesium-containing antacids or iron, cefdinir absorption may decrease. It is recommended to allow 2 hours between cefdinir administration and the administration of these agents.
This drug is mainly excreted by the kidneys. Dose adjustments may be required for patients with renal impairment or patients on dialysis. Approximately 18.4% of a 300 mg dose of cefdinir was found unchanged in the urine after a 300 mg dose was administered during a pharmacokinetic study of 21 individuals. A large proportion of the administered dose is excreted in the feces, although the majority is found in the urine.
The average volume of distribution of cefdinir in adults is about 0.35 L/kg and 0.67 L/kg in children. Another resource estimates the volume of distribution in adults at 1.56–2.09 L/kg. Cefdinir is found to be distributed in various tissues at clinically effective concentrations. It may be found in the epithelial lining fluid, bronchial mucosa, tonsils, sinuses, skin blister fluid, as well as the middle ear fluid. Third-generation cephalosporins such as cefdinir cross the blood-brain barrier and are found in high concentrations in the cerebrospinal fluid, unlike their first and second generation counterparts. The wide tissue distribution of cefdinir allows it to treat a variety of infections throughout the body.
The renal clearance in healthy adults in a pharmacokinetic study was 2.0 (± 1.0) mL/min/kg and the clearance in patients with renal failure was lower, decreasing in proportion to the degree of renal impairment. Dose adjustment is required in patients with renal impairment.
