Description of Retapamulin

Retapamulin is a pleuromutilin antibiotic [1].

Retapamulin is developed for topical treatment of skin infections which is mainly caused by gram-positive organisms, β-hemolytic streptococci and coagulase-negative staphylococci. Retapamulin is especially used against those drug resistance strains. In the in vitro studies, retapamulin demonstrates potent activity and a broad spectrum. It shows excellent antimicrobial activities against S. aureus, S. epidermidis, S. saprophyticus, S. pyogenes, S. agalactiae and Viridans group streptococci with MIC50 values of 0.06μg/ml, 0.06μg/ml, 0.12μg/ml, 0.008μg/ml, 0.016μg/ml and 0.03μg/ml, respectively. Retapamulin plays its antibiotic role through binding to a unique site of the bacterial ribosome [1, 2].

In vivo Formulation Calculator (Clear solution) of Retapamulin

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)

mg/kg g μL

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

%DMSO %

Calculation results:

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
