Antibiotic Level, Ticarcillin
Also known as: ML TICAR
Use
Ticarcillin is an antimicrobial drug, and its therapeutic monitoring is important to ensure efficacy and avoid toxicity. Monitoring the levels of ticarcillin helps in the adjustment of dosage to achieve optimal therapeutic concentrations, considering patient-specific factors such as renal function and body weight, which can affect drug clearance. It is particularly useful in managing patients with variable pharmacokinetics, such as those with renal impairment or critical illness, where standard dosing may not achieve desired drug levels.
Special Instructions
Not provided.
Limitations
The presence of other antimicrobial agents may interfere with the bioassay measurements, leading to inaccurate results. Furthermore, variability among patients due to differences in pharmacokinetics can affect the concentration of ticarcillin observed, such as due to renal function or interactions with other medications. The assay does not establish trough levels, and peak levels might vary based on dosage and route of administration.
