Abstract
The present invention has as objective the stabilization of a fluoroether compound against degradation by acid substances. The stabilizers proposed are selected among propylene glycol, polyethylene glycol, hexylene glycol, 1,3-butylene glycol and a saturated cyclic alcohol preferably menthol and are used for preparing stable pharmaceutical compositions of a fluoroether compound. Method for stabilizing a fluoroether compound and use of stabilizers agents for precluding the degradation of a fluoroether are also described.
