FIG. 1 depicts a method 100 for treating skin infections. The method 100 comprises a step 105: topically applying to an infection of the skin for treatment period prescribed by a physician, at ambient temperature, without using cryotherapy, a composition for treating skin infections, comprising: in 100 parts of the composition, 1-99 parts of a pharmaceutically acceptable excipient; 99-1 parts of a keratolytic; 99-1 parts ethyl pyruvate; and 99-1 parts povidone iodine, resulting in a higher cure rate than would be achieved if the infection were treated by topically applying a control composition having only the keratolytic and balance being the pharmaceutically acceptable excipient.

Ethyl alcohol may be used to dissolve components of the pharmaceutically effective composition for treating infections caused by HPV. Alcohols, such as isopropyl alcohol, methyl alcohol, propyl alcohol, ethyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, and lanolin alcohol, may be used for dissolving or taking up the components in the pharmaceutically effective composition for treating infections caused by HPV. Alternatively, for example, for topical formulations, pharmaceutically acceptable excipients may comprise solvents, emollients, humectants, preservatives, emulsifiers, and pH adjusting agents. Suitable solvents include acetone, glycols, polyurethanes, and others known in the art. Suitable emollients include mineral oil, propylene glycol dicaprylate, lower fatty acid esters, lower alkyl ethers of propylene glycol, cetyl alcohol, cetostearyl alcohol, stearyl alcohol, stearic acid, wax, and others known in the art. Suitable humectants include glycerin, sorbitol, and others known in the art. Suitable emulsifiers include glyceryl monostearate, glyceryl monoleate, stearic acid, polyoxyethylene cetyl ether, polyoxyethylene cetostearyl ether, polyoxyethylene stearyl ether, polyethylene glycol stearate, propylene glycol stearate, and others known in the art.

DGMSE may be known as 2-(2-ethoxyethoxy)ethanol, Carbitol, Carbitolcellosolve, Transcutol, Dioxitol, Poly-solv DE, and Dowanol DE. Not wishing to be bound by theory, polyethylene glycol (PEG), ethylene glycol (EG), polypropylene glycol (PPG), propylene glycol (PG) and the diethylene glycol monosubstituted ether (DGMSE) may hydrogen bond to trace nucleophiles that may be contaminants in the pharmaceutically acceptable excipients, thereby reducing the nucleophilic strength of the trace nucleophiles. This may reduce the chance that ethyl pyruvate may decompose by undergoing disadvantageous nucleophilic attack by the trace nucleophiles. Therefore diethylene glycol monosubstituted ether (DGMSE) or silicones such as dimethicone or cyclomethicone may be useful as pharmaceutically acceptable excipients.

In one embodiment, patients topically treated with the pharmaceutically effective composition for treating infections caused by HPV compounded into a polypropylene glycol (PPG, molecular weight from about 300 to about 2500), propylene glycol (PG), polyethyleneglycol (PEG, molecular weight from about 100 to about 1000) or ethylene glycol ointment or cream showed very little evidence of any systemic toxicities.

A pharmaceutically effective composition, in 100 parts, having from about 0.4 parts to about 0.6 parts povidone iodine USP, 12.0 parts to about 18.0 parts ethyl pyruvate, and 13.6 parts to about 20.4 parts salicylic acid USP may be formulated by mixing the components listed in Table 1, supra, according to the following general method 200.

In step 1 of the method 200, isopropyl alcohol, 2-(2-ethoxyethoxy) ethanol NF (Transcutol P), ethyl pyruvate, propylene glycol (1,2 dihydroxy Propane), Glycerin USP, salicylic acid USP, and butylated hydroxy toluene (BHT NF) are incrementally added with mixing in a high shear mixer for 30 minutes, forming a solution. In step 2 of the method 200, hydroxypropyl cellulose NF (HPC) is incrementally added to the solution of step 1 with continued mixing, resulting in a thickened mixture. In step 3 of the method 200, povidone Iodine USP and triethanolamine are incrementally added to the thickened mixture of step 2 with mixing, forming a thickened mixture that may be topically applied to an infection of the skin, e.g., a wart.

The pharmaceutically effective composition having, in 100 parts, from about 0.4 parts to about 0.6 parts povidone iodine USP, 12.0 parts to about 18.0 parts ethyl pyruvate, and 13.6 parts to about 20.4 parts salicylic acid USP and formulated by mixing the components listed in Table 1, supra, according to the general method 200, was topically applied to a total of 12 patients (n=12) having documented warts. These resistant wart patients had been previously treated with at least one therapy. Treatment in accordance with the method 100 resulted in a higher cure rate than would be achieved if the infection were treated by topically applying a control composition having only the keratolytic and balance being the pharmaceutically acceptable excipient.1 Patients ranged in age from 14 to 66 years old. The pharmaceutically effective composition of the present disclosure was exclusively used by patients to treat their verrucae of the lower extremity, including: the knee, lower leg, ankle, foot, and toes. No other treatments were provided. Biopsies were performed on most patients and confirmed verruca in all patients that were biopsied.

During the course of the study period, patients were instructed to use the pharmaceutically effective composition of the present disclosure, in the morning after a shower with a Band-Aid and at night before bed without occlusion. The patient was further instructed to self-debride daily with a file or pumice stone before application, wash and dry the area well before application, and change socks and shoes twice daily. The patient was seen every 2 weeks for reevaluation, debridement, and application in the office.

Following completion of the study and resolution of the warts, the patient was seen 2 weeks post-clearing for reevaluation, 4 weeks post-clearing for an additional check and at 8 weeks post-clearing for a final reevaluation confirming complete resolution before discharge.

Of the 12 patients treated with the pharmaceutically effective composition of the present disclosure, in our practice, all warts resolved, with most in 2-6 weeks. Of particular note was a very difficult case that involved 2 large mosaic verruca measuring 2 cm×3 cm on the plantar medial hallux and 4 cm×5 cm plantar heel respectively that were resistant to multiple therapies for 14 months. Previous treatments by 2 podiatrists and a dermatologist were unsuccessful using oral Vitamin A, oral cimetidine, a variety of topicals, laser and Candin injections. Biopsy confirmed diagnosis of verruca. After 20 weeks of being treated with the pharmaceutically effective composition of the present disclosure all lesions resolved with no reoccurrence.

We note of particular importance when using the pharmaceutically effective composition of the present disclosure was ensuring a lag time between showering and application and a lag time between application and putting on socks and shoe-gear. In addition we note that it is important to emphasize to patients to rub the pharmaceutically effective composition of the present disclosure well into and on the treated lesion and letting it dry before proceeding with daily activities.

Alternatively, a pharmaceutically effective composition, in 100 parts, for treating skin infections may be prepared according to the method 200, advantageously having in 100 parts of the composition, 0-99 parts of a pharmaceutically acceptable excipient, 49.9-10 parts of a keratolytic, 50-5 parts ethyl pyruvate, and 19-0.1 parts povidone iodine. The components/compositions are provided in Table 2, as follows.
