Physicochemical stability of high-concentration cefuroxime aqueous injection reconstituted by a centralised intravenous additive service.

Objectives: Hospital pharmacies provide centralised intravenous additive services (CIVAS), such as antibiotic reconstitution. The aim of this study was to demonstrate the physicochemical stability of high-concentration cefuroxime sodium in aqueous injections, which is mandatory for the centralised preparation of products with automation.

Methods: The physicochemical stability of three high-concentration injections (1.

Early-phase pharmacokinetics of enteral and parenteral nimodipine in patients with acute subarachnoid haemorrhage - a pilot study.

Objective: The pharmacokinetics of nimodipine following enteral administration in the early phase after subarachnoid haemorrhage (SAH) has not been described. If a sufficient absorption could be achieved with enterally administered nimodipine, this would be more feasible dosage form and result in a significant reduction in pharmaceutical costs given that the parenteral formulation of nimodipine currently used is tenfold more expensive than the enteral formulation.

Methods: This was a pilot study in which 17 patients with aneurysmal SAH were randomly assigned to receive nimodipine within 24 h after initial bleeding either as an 60 mg tablet/suspension at 4-h intervals, or as a continuous intravenous infusion of 2 mg/h.
