Process for the dissolution of drugs containing basic reacting nitrogen atoms |
| abstract |
Preparation of soluble basic medicaments having one or more basic nitrogen atoms in their structure, esp. basic xanthine derivatives e.g theophylline and theobromines T - Alk - NH - CHR1CHR2R3 T=dialkylxanthinyl- Alk=C2-6 alkylene R1=H or lower alkyl- R2=H or OH R3=phenyl or hydroxyphenyl-. by reacting the basic medicament with an aryl-sulphonic acid R'1 and R'2 = same of different H-, phenyl-, C1-5 alkylphenyl-, alkyl which may form a ring opt. through O or N esp. benzene sulphonic acid, p-toluene sulphonic acid, D,L-camphorsulphonic acid, cyclohexylamidosulphuric acid. Preparation of soluble basic injections and aerosols. |
