Definitions

  • the present invention is generally directed to a dermatological formulation for topical application comprising an androstane steroid compound, where the formulation has improved stability and often also improved vasoconstrictor potency.
  • Androstane steroid compounds are a type of anti-inflammatory steroid and are described in U.S. Patent No. 4,335,121 to Phillipps et al. (Assignors to Glaxo Group Limited). Fluticasone propionate, an androstane steroid compound that is in accordance with the Phillips et al. patent, has very desirable anti-inflammatory, anti-pruitic, and vasoconstrictive properties.
  • a fluticasone propionate lotion is described in International Publication No. WO 00/24401 , published May 4, 2000, to Dow et al. (Assignors to Glaxo Group Limited).
  • This International Publication states that the fluticasone propionate lotion shows increased vasoconstrictor potency of fluticasone propionate over fluticasone propionate cream formulations but at a decreased concentration of occlusive agent under about 10.0 w/w %.
  • an occlusive agent such as mineral oil or paraffin, increases the vasoconstrictor potency of the topical steroid, but that can reduce the aesthetic appeal due to imparting an undesirable oily or greasy fee! to the skin.
  • high concentrations of occlusive agents can cause the formulation, which is an oil-in-water emulsion, to be unstable and invert to a water-in-oil emulsion that has the greasy feel.
  • the present invention provides a stable oil-in-water emulsion topical formulation comprising a solvent, an occlusive agent, a surfactant system, water, and an androstane steroid compound of the formula

  • the androstane steroid compound comprises fluticasone, or a pharmaceutically acceptable salt or ester thereof.
  • the present invention provides a process for topically treating a skin condition, such as corticosteroid-responsive dermatosis, atropic dermatitis, inflammation, eczema, erythema, papulation, scaling, erosion, oozing, crusting, pruritis, impetigo, epidermalysis bullosa, psoriasis, erythema, hidradenitis suppurative, warts, diaper rash, jock itch, and combinations thereof, by topically applying a stable oil-in-water emulsion topical formulation comprising a solvent, an occlusive agent, a surfactant system, water, and an androstane steroid compound of the formula

  • the topical formulation even though it has a high % of occlusive agent, does not impart a greasy feel to the skin.
  • the topical formulation of the present invention is a stable oil-in-water emulsion. Due to careful choosing of the surfactant system to have a particular HLB value in a range from about 7.0 to about 10.9, the formulation can have an increased amount of occlusive agent. Such increase results in improved VC potency, often with a VC ranking of I or II.
  • the formulation is free of the prior art problem of an increased amount of occlusive agent causing a formulation to be unstable and, thus, invert to a water-in-oil emulsion that imparts an undesirable greasy feel to the skin.
  • a water-in-oil emulsion is also disadvantageous in that it has poor content uniformity and is lacking in pharmaceutical elegance (i.e., fails to meet appearance requirements).

  • elevated temperatures typically from about 40°C to about 80°C
  • three phases are prepared: an aqueous phase, a non-aqueous phase, and a medicament slurry.
  • the aqueous phase and the non-aqueous phase are heated (about 40°C to about 80°C), while the medicament slurry is maintained near room temperature (about 15°C to about 40°C).
  • the three phases are combined in a mixing vessel where the temperature can be controlled, and the three phases are mixed so that the non-aqueous phase is emulsified and the medicament particles are uniformly dispersed.
  • the intensity of the mixing is variable.
  • the emulsion is cooled while the mixing continues. When the emulsion reaches the desired temperature (usually about 15°C to about 30°C), the emulsion is removed from the mixing vessel and filled into the appropriate container/closure system.
  • the following Laboratory Examples are intended merely to illustrate the formulation of the present invention and are not to be construed as limiting the scope of the invention. Unless indicated otherwise, all weight percentages are based on the total weight of the formulation.
  • vasoconstrictor evaluations were measured using a VC assay (McKenzie and Stoughton, Arch. Dermatol., 86, 608 (1962)), using a scale of I, II, III, IV, and V, where I is the highest potency ranking and V is the lowest potency ranking.
  • the VC assay according to McKenzie and Stoughton is a standard dermatological assay used to predict the potency of corticosteroid formulations. Potency is related to both side effect potential and efficacy in the treatment of mild to severe skin conditions, as mentioned above. Reactions of particular concern include skin thinning (atrophy, including telangectasia), and adrenal axis suppression, which can occur oftener under occlusions or when higher potency corticosteroids are employed.
  • Example 1 Three topical 0.05 w/w % fluticasone propionate formulations were prepared, where the first formulation and the second formulation were comparisons, and the third formulation was in accordance with the present invention. These formulations had the following respective ingredients, indicated in w/w %, and the following respective characteristics of VC and HLB.
  • Cream 1 was an old formulation for CUTIVATE® cream. Although the potency was high, the presence of 10.0 w/w% microcrystalline wax plus 40.0 w/w% liquid paraffin, for a high amount of 50.0 w/w% for the occlusive agent, made cream 1 very unstable. Cream 1 inverted from an oilrin-water emulsion to a water-in-oil emulsion, Hence, cream 1 was not suitable for marketing because of the phase inversion and because it lacked homgeneity. Moreover, cream 1 imparted greasy feel to the skin, which is undesirable. The HLB value of the surfactant system (glyceryl stearate and PEG-100 stearate, which blend is sold as ARALCEL 165) in cream 1 was 11.
  • cream 2 which is in accordance with the present invention, has both a high level of occlusive agent and excellent stability as an oil-in-water emulsion over long periods of time and not inverting to a water-in-oil emulsion. It is noted that cream 2 contained a high amount of 42.5 w/w % of occlusive agent, namely 10.0 w/w % of microcrystalline wax plus 32.5 w/w % of liquid paraffin. Also, even though cream 2 had a high amount of occlusive agent, cream 2 still had an excellent stability, and it remained as an oil-in-water emulsion.
  • the HLB value of the surfactant system in cream 2 was chosen to have a particular HLB value. More specifically, the HLB value of the surfactant system in cream 2 was approximately 9. It will be understood that various details of the invention may be changed without departing from the scope of the invention. Furthermore, the above description is for the purpose of illustration only, and not for the purpose of limitation-the invention being defined by the claims.
