실험 절차

In one aspect, provided herein is a pharmaceutical composition comprising a blend of separately lyophilized tazobactam and ceftolozane sulfate in an amount providing 1,000 mg of ceftolozane active per 500 mg of tazobactam active, further comprising less than 0.15%, 0.10%, 0.05% or 0.03% by weight; from 0.03-0.05%, 0.03-0.1% or 0.03-0.15% by HPLC; or even undectable amounts (e.g., less than about 0.03% by HPLC) of a compound of formula (III) detectable at a retention time relative to ceftolozane of 1.22 by high performance liquid chromatography (HPLC) using a Develosil column ODS-UG-5; 5 micrometers; 250×4.6 mm, a mobile phase of sodium perchlorate buffer solution (pH 2.5)/CH3CN 90:10 (v/v) at a 1.0 mL/min flow rate and oven temperature of 45° C. (hereinafter referred to as the “method of Example 2”).
