Considering the patient's history of a tubal pregnancy and current medications, which mechanism best explains a potential interaction between ibuprofen and penicillin that could impact treatment efficacy?
Ibuprofen inhibits penicillin binding to bacterial proteins, reducing its antibacterial effect. Ibuprofen induces CYP enzymes, which could increase penicillin metabolism leading to reduced efficacy. Ibuprofen may reduce renal clearance of penicillin, potentially affecting its therapeutic levels. Ibuprofen and penicillin compete for the same hepatic enzyme, leading to increased penicillin toxicity.
