|Description||Cefditoren Pivoxil (ME-1207) is a broad-spectrum antibiotic against Gram-negative and Gram-positive bacteria.|
Cefditoren has MIC50/MIC90 results for Moraxella catarrhalis and Haemophilus influenzae of 0.12/0.5 and < or = 0.008/0.015 mg/mL, respectively.  Cefditoren (MIC(90), 0.5 mg/mL) is 4- to 128-fold more active than comparison beta-lactams against the pneumoococci and was the most potent beta-lactam (including penicillin) versus beta-haemolytic streptococci. Cefditoren (MIC(90) in mg/mL/% susceptible) activity against all tested H. influenzae (0.03/100) and M. catarrhalis (0.06-0.5/100) is comparable to Cefixime and significantly greater than cefaclor. Cefditoren pharmacokinetics demonstrate a T(1/2) of 1.5-2 hours and C(max) values of 2.8 and 4.6 mg/mL, respectively with 200 or 400 mg doses of Cefditoren pivoxil.  Cefditoren possesses a broad-spectrum of cidal antibacterial activity against both Gram-positive and Gram-negative species with stability to many beta-lactamases of clinical importance.  Cefditoren is also effective against methicillin-susceptible strains of Staphylococcus aureus. Cefditoren has compared favorably against other orally administered antibiotics used against the most commonly isolated respiratory tract pathogens.  Cefditoren up-regulates the expression levels of Mrp2, Bcrp and Oat2, and down-regulate P-gp and Oct1 mRNA expression.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
