Description of intervention(s) / exposure
Treatment: Drugs - Ceftolozane/tazobactam

Experimental: Ceftolozane Tazobactam - Infected patients with external intraventricular drain will receive a single dose of Ceftolozane/ tazobactam (3000mg) over 1 hour and will undergo blood , csf and urine sampling at specific times over an 8 hour period.


Treatment: Drugs: Ceftolozane/tazobactam
This is an observational pharmacokinetic study whereby patients received a single dose of ceftolozane/tazobactam and plasma and cerebrospinal fluid samples were subsequently collected and analyzed to described the pharmacokinetics.
