The present invention provides a composition for topical administration of a polyhydroxy acid, such as lactobionate and especially zinc lactobionate, and low pH to an external body surface such as skin. The composition is designed to be highly effective in delivering low pH and zinc lactobionate across the layers of the skin to more effectively treat and prevent skin conditions involving a defective skin barrier such as eczema and severe dry skin.

Skin barrier composition

There is described a topical composition for application of an NSAID comprising ibuprofen, the composition comprising a solution or suspension of the NSAID as active ingredient in a residual carrier system comprising a polyhydric alcohol, a glycol ether, an ester of a higher fatty acid and optionally water, the ingredients of the residual carrier system having the following concentrations in percentages by weight: polyhydric alcohol 50-90 glycol ether 7.5-40 ester 0.5-5 water optional in which either the composition or the residual phase is in a single phase under ambient conditions and the maximum water concentration is that above which the composition or the residual phase exhibits signs of inhomogeneity.

Topical pharmaceutical formulation

A formulation for topical dermatological delivery of a medicinal or cosmeceutical or cosmetic active including a functional co-enhancer delivery system. The delivery system generally comprises a water-miscible solvent and Cor Cfatty acids or Calcohol in combination with a hydrocarbyl methyl siloxane emollient.

Topical formulation

Herein described is a topical composition for application of an NSAID, the composition comprising a solution or suspension of the NSAID as active ingredient in a residual carrier system comprising a polyhydric alcohol, a glycol ether, an ester of a higher fatty acid and water, and the ingredients of the residual carrier system have the following concentrations in percentages by weight::polyhydric alcohol 50-90%; glycol ether 7.5-40%; ester 0.5-5%; and water up to 10%. Either the composition or the residual carrier system is a single phase at ambient conditions. The composition may also comprise a volatile solvent such as ethanol or isopropyl alcohol.

A pharmaceutical composition comprises an active ingredient dissolved in an essentially non-aqueous carrier system comprising volatile and non-volatile components, in which the volatile component comprises a volatile non-solvent for the active ingredient and a volatile solvation additive for the non-solvent and the non-volatile component comprises a non-volatile non-solvent and optionally a non-volatile solvent for the active ingredient, the volatile and non-volatile non-solvents comprising silicone fluids of respectively different viscosity.

Pharmaceutical composition

A composition for topical application to a part of the body comprises a local anaesthetic and optionally a vasodilator as active ingredient dissolved in a blend of volatile and non-volatile solvents of different solvating capacities for the active ingredient. The vasodilator may comprise glyceryl trinitrate and the local anaesthetic may comprises an anaesthetic of the aminoamide or aminoester type. The volatile solvent may comprise a mixture of water with a C-Calcohol and the non-volatile solvent may comprise a polyhydric alcohol and optionally a glycol. A low-concentration vasodilator-containing composition is also described. The compositions allow a 'virtual injection' of the active ingredient to be delivered transdermally without general systemic uptake.

Composition for promoting vascular smooth muscle relaxation

A composition for topical application to a part of the body comprises a vasodilator, for example glyceryl trinitrate, as active ingredient dissolved in a blend of volatile and non-volatile solvents of different solvating capacities for the vasodilator. The vasoldator is present in the composition at a concentration at or slightly below saturation, whereby evaporation of the volatile solvent in use will maintain the vasodilator at saturated or super-saturated concentrations in the residue, whereby the vasodilator will become saturated or supersaturated in the solvent remaining and, as the active ingredient passes through the skin and is absorbed in the bloodstream, and thus becomes depleted in the residual composition, continuing evaporation of volatile solvent will maintain the active ingredient substantially at saturation or supersaturation level in the residual composition throughout the major part of the absorption phase, thereby maximising absorption levels but at a moderate dosage level.

A composition for topical application of an NSAID comprises a solution or suspension of the NSAID in a carrier system comprising a polyhydric alcohol, a glycol ether and an ester of A higher fatty acid, the carrier system being present as a single phase at ambient temperatures. The NSAID may be diclofenac as diclofenac acid. The polyhydric alcohol may be a glycol such as isopropylene glycol and the glycol ether may be a diethylene glycol ether such as diethylene glycol monoethyl ether.
