Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 37 words
A method for reducing mucin viscosity in humans which comprises administering to said human effective a pharmaceutically effective dose of one or more compounds having protected sulfhydryl groups which metabolize in vivo to produce free sulfhydryl groups.
Claim 2
Independent Claim 37 words
A method for reducing mucin viscosity in humans which comprises administering to said human effective a pharmaceutically effective dose of one or more compounds having protected sulfhydryl groups which metabolize in vivo to produce free sulfhydryl groups.
Claim 3
Dependent Claim 163 words
