Dermacort

Marlborough Pharmaceuticals

Description

The cream formulation of Dermacort was developed in order to optimise the release and partition of its active ingredient, hydrocortisone, into the skin which is presented as a saturated or near saturated solution in aqueous propylene glycol, which represents the continuous phase of the emulsion system. It has been shown, by the vasoconstrictor assay on normal skin, that in this environment, a 0.1% concentration of the hydrocortisone is equivalent to the 1% concentration where the drug substance is in suspension. Clinical studies have confirmed that 0.1% Dermacort is equivalent to 1.0% hydrocortisone cream BP/BPC whilst the reduced strength of Dermacort increases the margin of safety.
