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

Targets/IC50/Ki
16S ribosomal RNA
In vitro

Paromomycin is an aminoglycoside that is active against Gram-negative and many Gram-positive bacteria as well as some protozoa and cestodes. In vitro analysis on the sensitivity of amastigotes in a murine macrophage model showed that L. major and L. tropica isolates (ED50s in the range of 1 to 5 μM) are more sensitive than L. braziliensis (ED50, <12 μM) and L. mexicana (ED50, 39 μM) isolates. L. donovani shows intermediate sensitivity (ED50, 6 to 18 μM), except for one Indian strain, DD8, which had an ED50 of >150 μM.

In vivo

In both experimental models and clinical cases of CL, lesions caused by L. major treated with paromomycin ointment resolved faster and more completely than lesions caused by L. amazonensis and L. panamensis.
