Hi deepak, welcome and thanks for your question.  You asked how to reduce side effects of bisphosphonates, but we would need to know which side effects you are referring to.  If you are having stomach problems with the med there are things you can take to alleviate these, but your Dr. would have to determine which to prescribe.

 

If you are referring to bone or joint pain, then typically they prescribe an over-the-counter pain med or anti-inflammatory for that.

 

There are several new drugs in the pipeline, but they haven't been approved yet by the FDA.  All medications have their own side effects and I don't know of a single drug/supplement that doesn't have some side effects.

 

Strontium Citrate is an over-the-counter supplement that is used for osteoporosis which you could look into.  See Phyllis' SharePost on the Home page about this option.  There's also Fosteum, which you can read about at this article.  Fosteum has isoflavone isolated from soy, so if you have any allergies to soy or have had cancer, you wouldn't be able to take this since we don't know how soy reacts with cancer.  Ask your Dr. if he or she has any suggestions that could help you.

 

I hope this helps, and if you have another question just post again.

respected mam,

                       thanks for your reply.

 

The adverse events of the nitrogen-containing bisphosphonates are reviewed. Oral bisphosphonates (alendronate, risedronate and ibandronate), mainly used for the treatment of osteoporosis, have been associated with adverse events from the upper gastrointestinal tract, acute phase response, hypocalcaemia and secondary hyperparathyroidism, musculoskeletal pain, osteonecrosis of the jaw and ocular events. Intravenous bisphosphonates (pamidronate, ibandronate and zoledronic acid), used in oncology and for the treatment of osteoporosis, have been associated with all the above adverse events, except those from the upper gastrointestinal tract. Moreover, pamidronate and zoledronic acid have been associated with renal toxicity. Association of bisphosphonates with atrial fibrillation and atypical fractures of the femoral diaphysis remains uncertain. There are a few case reports relating bisphosphonates to cutaneous reactions, oral ulcerations, hepatitis and esophageal cancer. Generally, intravenous are more potent than oral bisphosphonates and the frequency and severity of some of the bisphosphonate- associated adverse events are dose and potency dependent. use of three oral bisphosphonates nearly triples the

risk of developing bone necrosis,a condition that can lead to disfigurement

and incapacitating pain, say researchers in an article in the Jan. 15 online issue of

The Journal of Rheumatology.Researchers at University of British Columbia (UBC) and

Vancouver Coastal Health Research Institute (VCHRI) conducted an epidemiologic study of bone necrosis and bisphosphonates taken by women to help

prevent bone fractures due to osteoporosis.This study of 87,837

elderly patients was the first to explore the link between bone necrosis and the bisphosphonates alendronate, etidronate and risedronate.

so can u suggest me  that how i can minimise these side effects? is there any combination which i can try with bisphophonates therapy to reduce all these side effects and get good additive effect i.e beter improvement in bone parameters.

or can u suggest me any new combinations which has not been tried before for osteoporosis but may be very effective and safe for treatment as compared to present therapies. i am a research student so i can test that newer combination on osteoporotic rat models and find out the results and inform you about it. so i will be very thankful to you if you suggest me some newer effective and safer combinations which has not been tried till date but can be useful in future.

 

with regards

deepak

Hi deepak, the only other meds I can think of are mentioned in my original reply, have you had a chance to read about them yet?  The pipeline drug that hasn't been approved yet is Denosumab if you want to read about it here's a NEJM article on it.  Keep in mind that it's NOT available yet or approved, but we may hear something favorable by Oct 2009.  Here's a study done on it if you aren't familiar with it.  Check out these three possible suggestions to see what you think (Fosteum, Strontium Citrate (US available) Strontium Ranelate (EU available) and Denosumab (not approved yet in US).  There's also the non bisphosphonate meds like Forteo see the previous link from the Cleveland Clinic, Miacalcin (Calcitonin), Evista (women only) and HRT (women only).

 

Good luck in your search!!
