Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
In the treatment of bone disorders, a method to increase the amount of both the osteomineral deposit and the osteoid present within bone by administration to a subject in need of said treatment an effective amount of a prostaglandin having the structure ##STR3## or the pharmacologically acceptable salts thereof wherein: A is ethylene or cis-vinylene: M is oxo, ##STR4## R is hydrogen or methyl; and Ar is phenyl or monosubstituted phenyl, said monosubstituent being fluoro, chloro, bromo, trifluoromethyl, methyl, methoxy and phenyl.
Claim 2
Dependent Claim
82 words
In the treatment of bone disorders, a method to increase the amount of both the osteomineral deposit and the osteoid present within bone by administration to a subject in need of said treatment an effective amount of a prostaglandin having the structure ##STR3## or the pharmacologically acceptable salts thereof wherein: A is ethylene or cis-vinylene: M is oxo, ##STR4## R is hydrogen or methyl; and Ar is phenyl or monosubstituted phenyl, said monosubstituent being fluoro, chloro, bromo, trifluoromethyl, methyl, methoxy and phenyl.
Claim 3
Dependent Claim
20 words
A method according to claim 1 wherein M of said prostaglandin is oxo, R is hydrogen and Ar is phenyl.
Claim 4
Dependent Claim
20 words
A method according to claim 1 wherein M of said prostaglandin is ##STR5## R is hydrogen and Ar is phenyl.
Claim 5
Dependent Claim
17 words
A method according to claim 2 wherein the magnesium salt of 2-descarboxy-2-(tetrazol-5-yl)-11-desoxy-15-keto-16-phenyl-ω-tetranor prostaglandin E 0 is administered.
Claim 6
Dependent Claim
59 words
A method according to claim 1 wherein said bone disorder is osteopenia including osteoporosis, osteomalacia, osteitis fibrosa cystica and osteolysis; a pathological change in the dynamic balance of the blood serum calcium and bone calcium levels; peridontal disease; a fracture and said treatment enhances the healing rate of said fracture or bone loss associated with osteogenic carcinomas and tumors.
Claim 7
Dependent Claim
74 words
A method according to claim 1 wherein said prostaglandin is administered orally in a suspension or solution with water, ethyl alcohol or vegetable oil or administered orally in tablet or capsule form alone or in combination with excipients, binders and solid diluents such as corn starch, talc, gum arabic acacia, polyvinylpyrrolidone, clay, lactose, sucrose or dextrose at doses containing 2 microgram/kg to 0.2 milligrams/kg of said prostaglandin with up to 5 doses per day.
Claim 8
Dependent Claim
52 words
A method according to claim 1 wherein said prostaglandin is administered by injection intramuscularly, intravenously or subcutaneoulsy in a sterile mixture or solution with such diluents as normal saline or water and ethyl alcohol at doses containing 0.5 microgram/kg to 50 micrograms/kg of said prostaglandin with up to 5 doses per day.
