Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
102 words
A method for treating osteoporosis, in humans or lower animals afflicted with or at risk to osteoporosis, comprising administering to said human or lower animal an effective amount of a bone resorption inhibiting polyphosphonate according to the following schedule: (a) a period of from about 1 day to about 90 days during which said bone resorption inhibiting polyphosphonate is administered daily in a limited amount; followed by (b) a rest period of from about 50 days to about 120 days; and (c) repeating (a) and (b) two or more times where a net increase in bone mass said human or animal results.
Claim 2
Independent Claim
102 words
A method for treating osteoporosis, in humans or lower animals afflicted with or at risk to osteoporosis, comprising administering to said human or lower animal an effective amount of a bone resorption inhibiting polyphosphonate according to the following schedule: (a) a period of from about 1 day to about 90 days during which said bone resorption inhibiting polyphosphonate is administered daily in a limited amount; followed by (b) a rest period of from about 50 days to about 120 days; and (c) repeating (a) and (b) two or more times where a net increase in bone mass said human or animal results.
