Definitions
- TREATMENT FIELD OF THE INVENTION relates to formulations for topical application of anti- inflammatory steroids alone or in combination with anti-bacterial or antifungal drugs.
- the formulations are useful for a variety of skin conditions due to the tolerance, efficacy and ease of use and application over large affected areas of the skin of both haired and non-haired animals.
- Conditions treated by the present invention include allergic dermatitis, inclusive of contact dermatitis, atopic dermatitis, and secondary complications in the form of bacterial infections such as by Staphylococcus species and fungal/yeast infections such as caused by Malassezia species.
- Atopic dermatitis is a genetically predisposed inflammatory and pruritic skin disease with characteristic clinical features. It is a well recognized disease in man and dogs but poorly understood in other mammals.
- Atopic dermatitis is associated most commonly but not exclusively with immediate type hypersensitivity characterized by the production of IgE antibodies to environmental allergens.
- Affected animals and man can have associated food allergies and commonly develop secondary infections with skin and mucosal commensal organisms namely the bacteria Staphylococcus spp. and the yeast Malassezia spp.
- Topical formulations of corticosteroids have been known since the 1950s as treatment for various inflammatory skin conditions such as atopic dermatitis, eczema etc. Topical steroidal preparations are also used in combination with antibacterial or antifungal agents in disease conditions that include an inflammatory component but all have been limited by practicality to non haired skin.
- formulations of topical steroids have involved suspensions or solutions of the steroid substance in vehicles that are based on oils, waxes or organic solvents.
- United States Patent 5,958,391 recites a formulation that comprises 0.5-2.5% hydrocortisone (HC), 2.5-7.5% elemental sulfur, 90-97% in a vehicle which is hydrocarbon jelly and aqueous carboxypolymethylene. This is intended for scalp application.
- HC hydrocortisone
- elemental sulfur 90-97%
- vehicle which is hydrocarbon jelly
- carboxypolymethylene This is intended for scalp application.
- United States Patent 4,918,065 describes a cream or ointment type of formulation of a steroid dispersed in a base consisting of both a water/oil and an oil/water emulsion with high proportions of waxy substances
- United States Patent 4,738, 956 discloses pharmaceutical preparations with a mix of 20-40% fatty alcohol (C 12-22), 30- 60% of volatile silicone, 0.1-10% hydrocortisone and preservative, emulsifier etc. The aim was to provide a silky non-greasy delivery system capable of spreading the ingredient smoothly and evenly without leaving a residue and increasing percutaneous absorption and bioavailability.
- United States Patent 4,370,322 there are described steroid formulations with only fatty substances as vehicle, such as dibutyl adipate, isopropyl myristate, wax and paraffin oil.
- United States Patent 4,363,806 describes and claims a formulation of steroid in a multiple emulsion vehicle which is a hydrophilic solvent-in-oil-in- water emulsion.
- the steroid is dissolved in propylene glycol (PG) and emulsified in an oil phase.
- PG propylene glycol
- the solvent-in-oil emulsion is emulsified in an aqueous solution giving rise to the emulsion.
- Another type of formulation uses organic solvents such as alkanols and polyhydric alcohols.
- organic solvents such as alkanols and polyhydric alcohols.
- United States Patent 3,899,580 describes topical corticosteroid formulations containing only 8-18% water and 60-90% solvents such as ethanol, PG and glycerine.
- United States Patent 4,353,896 describes a topical steroid formulation prepared in 15% dimethylsulphoxide as solvent as well as 10% isopropyl alcohol (IP A).
- prior art formulations are typically based on viscous, solid or semisolid waxes and fatty ingredients and therefore in application to large areas of the skin or skin surfaces that are covered in hair, these prior art formulations do not lend themselves to even and extensive application. This results in poor appearance of skin and/or hair (such as matting of hair, stickiness, greasy appearance, smearing to surfaces that come in contact, loss of dosage by these means etc).
- the active ingredients in some cases are not dissolved and are subject to loss or poor bioavailability.
- Many formulations are based on high proportions of organic solvents such as ethanol, propylene glycol, isopropyl alochol and polyethylene glycol. These solvents either tend to irritate the skin or leave a greasy appearance on application.
- corticosteroids while useful in treating inflammatory skin conditions can have, in addition, undesirable side effects due to systemic absorption.
- the suppression of the HPA axis (hypothalamic-pituitary-adrenal) by systemic availability of steroids is well known.
- Other potential side affects are Gushing' s syndrome, glucosuria and hyperglycemia. The risk of side affects increase in cases where anti-inflammatory treatment is required over large areas of skin.
- the method and formulation of the present invention has overcome this problem and is a superior alternative to systemic corticosteroid treatment in the treatment of haired animals (mammals) with allergic dermatitis without the danger of systemic toxic side effects of corticosteroids.
- Another object of the invention is to provide a formulation that has low amounts of waxy, oily and solid substances and solvents to minimize greasy feel, and that avoids accidental removal of product by contacting surfaces and irritation and drying of skin due to solvents. Practically this formulation and method relies on being applied after a shampoo and to the wet hair. Thus aiding in the spreadability and retaining the moisture in the skin and hair and even replacing shampoo removed sebum and natural conditioning oils.
- a further object of the invention is to provide a method for treatment of haired skin and non-hair skin with a topically administered formulation of a steroid either alone or in combination with an anti-bacterial and/or an antifungal agent.
