The present invention provides a gel combination comprising: polycarbophil in an amount comprised from 1 to 5% by weight; polyvinylpirrolidone in an amount comprised from 4 to 8% by weight; glycerine in an amount comprised from 1 to 10% by weight; and propyleneglycolin an amount comprised from 20 to 40% by weight; wherein: the weight ratio between polyvinylpirrolidone:polycarbophil is comprised between 1:1 and 4:1, the weight ratio between glycerine:polycarbophil is comprised from 0.5:1 to 2:1, and the weight ratio propyleneglycol:polycarbophil is comprised from 8:1 to 20:1. The invention also provides transparent compositions comprising such gel combinations as well as processes for their preparation and the use thereof as a medicament. Due to the specific excipients, % by weight, and weight ratios forming the combination, the resulting compositions show a high bioadhesivity and bioavailability of the active ingredient, without toxic adverse effects.
