Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
49 words
A topical antiviral pharmaceutical composition consisting essentially of an inert carrier and uniformly distributed therein 0.05 to 20 mgm of at least one nucleoside triphosphate or deoxynucleoside triphosphate and 0.5 to 100 mgm of at least one complex-former for bivalent cations per gram of total weight of said composition.
Claim 2
Dependent Claim
49 words
A topical antiviral pharmaceutical composition consisting essentially of an inert carrier and uniformly distributed therein 0.05 to 20 mgm of at least one nucleoside triphosphate or deoxynucleoside triphosphate and 0.5 to 100 mgm of at least one complex-former for bivalent cations per gram of total weight of said composition.
Claim 3
Dependent Claim
37 words

Claim 4
Dependent Claim
18 words
An antiviral composition of claim 1, wherein said complex-former is sodium pyrophosphate and said triphosphate is adenosine triphosphate.
