lactated ringers + oxacillin

A combination of **Lactated Ringer's injection** and **oxacillin** used for intravenous administration, primarily to deliver fluid and electrolytes while obtaining antimicrobial effects against susceptible organisms, mainly penicillinase-resistant Staphylococcus species. **Lactated Ringer's injection** is a balanced electrolyte solution providing sodium, potassium, calcium, chloride, and lactate, commonly used as an intravenous fluid and diluent. **Oxacillin** is a beta-lactam antibiotic of the penicillinase-resistant class, effective against penicillinase-producing staphylococci. The combination is generally prepared for co-infusion or Y-site administration in clinical settings and is intended for settings where both rehydration and anti-staphylococcal therapy are needed.
