Abstract

Abstract The regeneration of animal tissues by intramuscular injections containing a substituted ethylamine in combination with a macromolecular substance for the purpose of intravascular transportation and or inhibition of hydrolysis of the compound after injection. The ethylamine moiety is selected from the group consisting of lidocaine, butethamine, chloroprocaine, dibucaine, hexylcaine, mepivacaine, piperocaine, benoxinate, naepaine, phenocaine, cyclomethycaine, proparacaine, pramoxine, tetracaine, dimethisoquin, procaine and 2-(4 imidazolyethylamine) or histamine and diphenhydramine. The macromolecule is selected from the group consisting of polyvinylpyrollidone, methyl cellulose, dextran, gelatin and polyoxyethylene sorbitan mono-oleate.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 61 words
A method of minimizing scarring in a patient suffering from burns which comprises administering to said patient by injection into tissues adjacent said burn injury an aqueous composition of about 50 mg. to about 2.5 g. of a pharmaceutically acceptable salt of procaine and about 100 mg. to about 5 g. of polyvinylpyrrolidone having a molecular weight of 5,000 to 50,000.
Claim 2
Independent Claim 61 words
A method of minimizing scarring in a patient suffering from burns which comprises administering to said patient by injection into tissues adjacent said burn injury an aqueous composition of about 50 mg. to about 2.5 g. of a pharmaceutically acceptable salt of procaine and about 100 mg. to about 5 g. of polyvinylpyrrolidone having a molecular weight of 5,000 to 50,000.
Claim 3
Dependent Claim 29 words
The method of claim 1 wherein said aqueous composition comprises about 1.5 percent of an alcohol, about 5 percent of a procaine salt and about 10 percent of polyvinylpyrrolidone.
