Safety, tolerability, and pharmacokinetics of a 2 g subcutaneous dose of ceftriaxone as an alternative to intravenous delivery.

ABSTRACT: Subcutaneous delivery of antibiotics is a practical alternative to intravenous administration. Ceftriaxone is commonly used for a variety of infections with limited data on the safety and pharmacokinetics of a 2 g subcutaneous dose. This was a prospective, self-controlled cross-over study in 20 stable inpatients receiving ceftriaxone for their infection. Following an intravenous dose, participants received a single dose of 2 g subcutaneous ceftriaxone, in 50 mL normal saline via gravity feed. Capillary dried blood spots were collected at baseline, 1, 2, 4, 8, and 24 hours following the subcutaneous and intravenous doses. Pain scores and infusion site reactions (edema/erythema) were assessed. Ceftriaxone concentrations were measured using a validated liquid chromatography-tandem mass spectr
