Abstract

Aspirin compositions for oral and topical use are stabilized by reaction with potassium hydroxide.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A medicinal drug which is mixed with a liquid carrier for oral or topical application to mammals to treat malodies conventionally treated using aspirin product, said drug being formed by combining a salicylic acid with potassium hydroxide in a water based solution to form potassium salicylic acid which is thereafter dehydrated to form a stabilized dry potassium salicylic acid. 
     
     
       2. The medicinal drug of  claim 1  wherein the salicylic acid is combined to a point of supersaturation in the water based solution. 
     
     
       3. The medicinal drug of  claim 1  mixed with water to form a dosing solution with a pH in the range of 8 to 10. 
     
     
       4. The medicinal drug of  claim 1  mixed with a water based carrier including a dermtologically acceptable lotion, cream, gel or ointment with a resulting pH which is compatible to mammalian skin. 
     
     
       5. The medicinal drug of  claim 1  wherein approximately one part by weight potassium hydroxide is combined in the water based solution with two parts by weight salicylic acid. 
     
     
       6. A medicinal drug which is mixed with a liquid carrier for oral application to mammals to treat malodies conventionally treated using aspirin product, said drug being formed by combining a acetylsalicylic acid with potassium hydroxide in a water based solution to form potassium acetylsalicylic acid which is thereafter dehydrated to form a stabilized dry potassium acetylsalicylic acid. 
     
     
       7. The medicinal drug of  claim 6  mixed with water to form a dosing solution with a pH in the range of 8 to 10. 
     
     
       8. The medicinal drug of  claim 6  mixed with a water based carrier including a dermtologically acceptable lotion, cream, gel or ointment with a resulting pH which is compatible to mammalian skin. 
     
     
       9. The medicinal drug of  claim 6  wherein approximately one part by weight potassium hydroxide is combined in the water based solution with two  approximately  1 . 3 parts by weight acetylsalicylic acid.
