Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

In vitro
Cefprozil is particularly active against the Gram-positive organisms Streptococcus pyogenes, pneumoniae and agalactiae and against methicillin-susceptible Staphylococcus aureus. Cefprozil is also moderately active against Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae, many Enterobacteriaceae and certain anaerobic organisms, and is relatively stable to hydrolysis by a number of beta-lactamases. Cefprozil is a newer oral Cephalosporin with a spectrum of activity against organisms that include gram-positive and gram-negative pathogens. Cefprozil is active (susceptibility, less than or equal to 8 mg /mL; moderate susceptibility, 16 mg/mL; resistance, greater than or equal to 32 mg/mL) against gram-positive species such as streptococci, methicillin-susceptible staphylococci, and Listeria monocytogenes. Cefprozil is at least as active as cefuroxime, cefaclor, and cephalexin against all organisms tested, but is fourfold less active than doxycycline against E coli and 16-fold less active than clarithromycin versus S pneumoniae. Cefprozil is as active as amoxicillin/clavulanate against K pneumoniae and E coli.
In vivo
Cefprozil results in the mean peak concentration (Cmax) in infant dogs (21.2 mg/mL) and adult dogs (27.8 mg/mL). Cefprozil results in the areas under the concentration-time curve (AUC, in infant dogs: 121 mg.hr/mL, in adult dogs: 130 mg.hr/mL), half-lives (T 1/2, in infant dogs: 4.7 hours, in adult dogs: 4.7 hours) or urinary recovery rates (UR, in infant dogs: 36.3%, in adult dogs: 34.7%) between the 2 groups.
