Appropriate levels of an active pharmaceutical ingredient (API) in medicines must be present in a medical product for the patient to receive therapeutic value. High performance liquid chromatography (HPLC) was used to develop a methodology to test for the API in Ampicillin and Cefuroxime drugs. Following the regulations of the Distributed Pharmaceutical Analysis Lab (DPAL) out of Notre Dame system sustainability requirements linearity, precision, accuracy/range, spike/degraded spike, limit of detection /quantitation, tailing factor, and number of theoretical plates were experimentally determined to meet the excepted standards.


The ampicillin methodology is finished and ready to be submitted to DPAL for verification. For Cefuroxime, the spikes need to be completed.
