Pharmacokinetics and Safety of Antimicrobial Agents Administered by Subcutaneous Route in Patients AGEd Over 65 Years

Elderly people are more prone to develop infection with a poorer prognosis compared to young people. Physicians may encounter difficulties regarding antimicrobial agents administration route. In fact, poor venous access and behavioral disturbance are frequent issues. The subcutaneous (SC) route may be a safe alternative, but sparse data are available in the literature. The present study aims to describe Pharmacokinetics (PK) / Pharmacodynamics (PD) characteristics of antibiotics (amoxicillin/clavulanate, ceftriaxone and piperacillin/tazobactam) subcutaneous administration in patients aged over 65.
