Actonel (Risedronate Sodium) - Summary

 
 



ACTONEL SUMMARY

ACTONEL (risedronate sodium tablets) is a pyridinyl bisphosphonate that inhibits osteoclast-mediated bone resorption and modulates bone metabolism. Each ACTONEL tablet for oral administration contains the equivalent of 5, 30, or 35 mg of anhydrous risedronate sodium in the form of the hemi-pentahydrate with small amounts of monohydrate.

ACTONEL is indicated for the following:

POSTMENOPAUSAL OSTEOPOROSIS:

ACTONEL is indicated for the treatment and prevention of osteoporosis in postmenopausal women.

TREATMENT OF OSTEOPOROSIS:

In postmenopausal women with osteoporosis, ACTONEL increases BMD and reduces the incidence of vertebral fractures and a composite endpoint of nonvertebral osteoporosis-related fractures (see CLINICAL STUDIES). Osteoporosis may be confirmed by the presence or history of osteoporotic fracture, or by the finding of low bone mass (for example, at least 2 SD below the premenopausal mean).

PREVENTION OF OSTEOPOROSIS:

ACTONEL may be considered in postmenopausal women who are at risk of developing osteoporosis and for whom the desired clinical outcome is to maintain bone mass and to reduce the risk of fracture.

Factors such as family history of osteoporosis, previous fracture, smoking, BMD (at least 1 SD below the premenopausal mean), high bone turnover, thin body frame, Caucasian or Asian race, and early menopause are associated with an increased risk of developing osteoporosis and fractures. The presence of these risk factors may be important when considering the use of ACTONEL for prevention of osteoporosis.

GLUCOCORTICOID-INDUCED OSTEOPOROSIS:

ACTONEL is indicated for the prevention and treatment of glucocorticoid-induced osteoporosis in men and women who are either initiating or continuing systemic glucocorticoid treatment (daily dosage equivalent to 7.5 mg or greater of prednisone) for chronic diseases. Patients treated with glucocorticoids should receive adequate amounts of calcium and vitamin D.

PAGET'S DISEASE:

ACTONEL is indicated for treatment of Paget's disease of bone (osteitis deformans). Treatment is indicated in patients with Paget's disease of bone (1) who have a level of serum alkaline phosphatase at least 2 times the upper limit of normal, or (2) who are symptomatic, or (3) who are at risk for future complications from their disease, to induce remission (normalization of serum alkaline phosphatase).

Lipid profiles in women with early breast cancer receiving anastrozole with or without risedronate were examined within an international Phase III/IV study to assess for possible treatment related changes. Postmenopausal women with hormone receptor-positive breast cancer were assigned to 1 of 3 strata by risk of fragility fracture...

Evidence for safety and efficacy of risedronate in men with osteoporosis over 4 years of treatment: Results from the 2-year, open-label, extension study of a 2-year, randomized, double-blind, placebo-controlled study. [2012]
A 2-year, randomized, double-blind, placebo-controlled study in men with osteoporosis demonstrated that treatment with risedronate 35mg once a week significantly decreased bone turnover markers (BTMs) and increased bone mineral density (BMD).

Clinical Trials Related to Actonel (Risedronate)

Assess Bioequivalence of One 150 mg Risedronate Tablet Versus Two 75 mg Risedronate Tablets in Healthy Subjects [Completed]
This study is a randomized, open-label, crossover study to assess the bioequivalence of 1 risedronate 150 mg tablet versus 2 risedronate 75 mg tablets administered as a single oral dose. Approximately 320 subjects will be enrolled from 4 study centers in the U. S.

Safety, Pharmacokinetics, and Efficacy of 100, 150, and 200 mg Risedronate Administered to Women With Low BMD [Completed]
A Multi-center, Active-controlled (5 mg daily risedronate), Double-blind, Randomized, Sequential Escalating Dose Study to Assess Safety, Pharmacokinetics and Efficacy of 100, 150, and 200 mg Oral Risedronate Administered Monthly for Six Months in Postmenopausal Women with Low Bone Mineral Density.

Efficacy Study of Risedronate to Prevent Cancer Treatment-Induced Bone Loss in Prostate Cancer [Active, not recruiting]
Prostate cancer patients treated with LHRH agonists (e. g., leuprolide) lose bone mineral density. This is similar to post-menopausal osteoporosis. Risedronate is approved to prevent osteoporosis. We hypothesize that risedronate may also be effective in prostate cancer patients treated with LHRH agonists.

Safety and Efficacy of Risedronate in the Treatment of Osteogenesis Imperfecta in Children [Active, not recruiting]
Children with Osteogenesis Imperfecta (OI) have bone pain, low bone mass and fractures. There are no approved drugs for the treatment of OI in children, even though some intravenous (IV) bisphosphonates are used off-label in some countries. In a single dose, pharmacokinetic study, data showed that risedronate was well tolerated in 28 children with OI. This three year study will test the safety and efficacy of risedronate in the treatment of children with OI. For the first year, patients will be randomized to the risedronate and placebo groups in a 2: 1 ratio (two groups will receive risedronate, and one group will receive placebo). For the second and third years of the study, all patients will receive risedronate.

Impact of Vertebral Fracture Knowledge on Persistence in Subjects Taking Glucocorticoid Therapy [Completed]
To evaluate the effect of subject knowledge of their disease status on persistence in subjects receiving Actonel 5 mg daily over a 12-month period for the prevention and treatment of GIO.

Side effects:   I have not had any side effects, not even the heartburn that is the most common one.

I wait at least 30 minutes before I eat or drink anything. While I am supposed to wait at least 30 minutes before lying down again, I confess that on a couple of Wednesday mornings when I was especially tired, I did lay back down. Even then, however, I did not experience any heartburn.
