Composition & Brand Landscape

The active ingredient in ampicillin is simply ampicillin itself, which falls within the penicillin class of antibiotics. In Canada, it is marketed under the brand names Principen and Apo-Ampicillin. A variety of dosages are available, including capsules at 250 mg and 500 mg, as well as powdered formulations designed for intravenous administration. Bilingual labelling is prominent, reflecting Canada's commitment to supporting both English and French-speaking populations. The Canadian pharmaceutical market boasts several generic alternatives, manufactured by major companies such as Sandoz and Aurobindo. These generic options serve as cost-effective alternatives that don’t compromise the quality of care patients receive.
