ATC code J01CA20 covers combinations of ampicillin and amoxicillin, which are broad-spectrum beta-lactam antibiotics used for the treatment of various bacterial infections including respiratory tract, urinary tract, skin, and soft tissue infections. They are approved and commonly used antibiotics worldwide, typically formulated for oral administration in fixed-dose combinations.
Pharmacokinetics
Pharmacokinetic parameters estimated for healthy adults, assuming combined administration of amoxicillin 500 mg and ampicillin 500 mg given orally.
