Alendronate (Alendronate Sodium) - Summary

 
 



ALENDRONATE SUMMARY

Alendronate Sodium is bisphosphonate that acts as a specific inhibitor of osteoclastmediated bone resorption. Bisphosphonates are synthetic analogs of pyrophosphate that bind to the hydroxyapatite found in bone.

Treatment of Osteoporosis in Postmenopausal Women

Alendronate Sodium Tablet is indicated for the treatment of osteoporosis in postmenopausal women. In postmenopausal women,  Alendronate Sodium Tablet increases bone mass and reduces the incidence of fractures, including those of the hip and spine (vertebral compression fractures). [See Clinical Studies].

Prevention of Osteoporosis in Postmenopausal Women

Alendronate Sodium Tablet is indicated for the prevention of postmenopausal osteoporosis [see Clinical Studies].

Treatment to Increase Bone Mass in Men with Osteoporosis

Alendronate Sodium Tablet is indicated for treatment to increase bone mass in men with osteoporosis [see Clinical Studies].

Treatment of Glucocorticoid-Induced Osteoporosis

Alendronate Sodium Tablet is indicated for the treatment of glucocorticoid-induced osteoporosis in men and women receiving glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and who have low bone mineral density [see Clinical studies].

Treatment of Paget's Disease of Bone

Alendronate Sodium Tablet is indicated for the treatment of Paget’s disease of bone in men and women. Treatment is indicated in patients with Paget’s disease of bone who have alkaline phosphatase at least two times the upper limit of normal, or those who are symptomatic, or those at risk for future complications from their disease. [see Clinical Studies].

Important Limitations of Use

The optimal duration of use has not been determined. The safety and effectiveness of Alendronate Sodium for the treatment of osteoporosis are based on clinical data of four years duration. All patients on bisphosphonate therapy should have the need for continued therapy re-evaluated on a periodic basis. Patients at low-risk for fracture should be considered for drug discontinuation after 3 to 5 years of use. Patients who discontinue therapy should have their risk for fracture re-evaluated periodically.

Clinical Trials Related to Alendronate

Parathyroid Hormone (PTH) With Alendronate for Osteoporosis [Completed]
This study investigates the effectiveness of parathyroid hormone (PTH) in combination with alendronate, a standard treatment for osteoporosis that blocks or reduces bone loss. We are using alendronate because it may help protect patients against any possible harmful effects of PTH in cortical bone such as the long bones or hip. We are testing two different treatment schedules of PTH-one in which we give PTH daily and one in which we give PTH for 3 out of every 6 months in a cyclical fashion. The entire study is 21 months long; the active treatment period is 18 months with a 6-month followup period.

The main effects we will look for in this study are changes in body chemicals that are signs of bone formation or bone breakdown, and changes in bone density throughout the skeleton. We will randomly assign all study participants, who are women aged 50 and over, to either stay on alendronate alone, receive daily continuous PTH plus alendronate, or receive daily PTH for 3 months out of every 6 for a total of three separate 3-month cycles of PTH plus daily alendronate.

Study of Alendronate to Prevent and Treat Osteoporosis in Cystic Fibrosis Patients [Active, not recruiting]
The primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.

Pharmacokinetics of a Single 14C-Labeled Dose of Risedronate or Alendronate Followed by Once-a-Week Unlabeled Oral Dose [Completed]

Study of MK-217A/Alendronate Sodium 70-mg/Vitamin D3 5600 IU Combination Tablet (MK-0217A-329) [Not yet recruiting]
This study will assess the effect of 26 weeks of once-weekly treatment with MK-217A/Alendronate Sodium 70-mg/Vitamin D3 5600 IU Combination Tablet (Fosamax Plus 70/5600) on serum levels of 25-hydroxyvitamin D [25(OH)D].

Safety and Effectiveness of Oral Alendronate Therapy on Bone Mineral Density in HIV-infected Children and Adolescents With Low Bone Mineral Density [Recruiting]
HIV-infected children, youth, and adults have lower bone mineral density (BMD) than would be expected for HIV-uninfected people of similar age, weight and race. As the majority of perinatally HIV-infected U. S. children are entering or in adolescence, the potential for HIV-related impaired BMD during the adolescent peak of bone mass acquisition is of particular concern. The primary purpose of this study is to compare changes from pre-treatment levels of BMD of the lumbar spine after 24 and 48 weeks of alendronate treatment with placebo in HIV-infected children and adolescents.

Condition / reason:   osteopenia
Dosage & duration:   1 tab per week taken once a week for the period of 2years and ongoing
Other conditions:   none

Reported Results
Benefits:   Increased bone density by 11% first year.
Side effects:   Mild stomach discomfort.
Comments:   Once a week Fosomax, taken on empty stomach with plenty of water. Ability to stand or sit upright for at least 30 minutes after taking is required. My phyisican prefers this to once a month options, saying it is more effective.

 

Alendronate review by 61 year old female patient

  Rating
Overall rating:  
Effectiveness:   Ineffective
Side effects:   Severe Side Effects
  
Treatment Info
Condition / reason:   osteoporosis
Dosage & duration:   1 tablet weekly 70 mg taken once a week for the period of one year approximately
Other conditions:   mild depression
Other drugs taken:   effexor
  
Reported Results
Benefits:   No benefits that I can see. My doctor said it was not useful to do another bone scan to see if there had been a change in a year so I have no idea if there was any benefit. I have been experiencing fairly severe leg pains for the past year and could not find out what they were from. Did numerous tests, no results. Then I saw on the insert that side effects could be muscle, bone or joint pain and when I read a comment on here describing dull aching in one leg in particular radiating down from the hip and below the knee. I thought...that is me!!! So I am stopping this drug and waiting to see what happens with the new aches and pains. Maybe it is this drug. I hope so.
Side effects:   See above.
Comments:   Took alendronate for osteoporosis for over a year.
