Abstract
A novel use for a slow-release sodium fluoride preparation. Such slow-release sodium preparation is shown to provide a safe but effective level of fluoride in serum, optimal for the treatment of osteoporosis. It minimizes gastrointestinal side effects by limiting the amount of fluoride released in the stomach and it reduces rheumatic complications by avoiding toxic levels of fluoride in serum. The amount of fluoride absorbed is nevertheless sufficient to stimulate bone formation and prevent fractures. Thus, the maintenance of serum fluoride as encompassed in this invention, allows for a safe and effective treatment of osteoporosis.
Claims5
In a process for the treatment of patients having osteoporosis comprising orally administering to said patients about 50 mg sodium fluoride per day the improvement consisting essentially of the step of administering 25 mg. of sodium fluoride twice a day, to maintain a serum fluoride concentration at a therapeutic level above 95 ng/ml and less than about 190 ng/ml;
- each 25 mg. sodium fluoride dose being in a slow-release sodium fluoride carnauba wax formulation adopted to gradually release sodium fluoride in the small intestine.
