Aclasta: Zolendronic acid for Osteoporosis

Aclasta is an Osteoporosis drug sold in Europe. In the United states it is distributed under the name Reclast. ( If you wish to read the pages about the USA form, just click on Reclast )

Both of these drugs are forms of zoledronic acid. This is an Osteoporosis drug that is taken only once a year. It is given by an infusion. And this infusion is done in your doctor's office.

This once a year treatment is what many people really like about this Osteoporosis drug. It means they only need to go to their health care provider's office once each year for their Osteoporosis treatment. Many people like not to have to remember  a daily or a weekly pill. There is nothing to remember with this drug - just keep your annual appointment. And many doctors' offices are more than willing to let you know when it is time for you to come in for your infusion.

Now if you are considering it, you will want to know a bit more about this particular Osteoporosis drug. . You especially want to find out if there is anything that could pose a problem for you so read on....

Novartis is the company that manufactures Aclasta

Novartis is one of the largest pharmaceutical companies in the world.The drug received its FDA approval after a three year study called Pivotal Fracture Trial  . This trial showed that the drug increased bone strength and it reduced fractures of the hip, spine and other areas such as wrists, arms, legs or ribs.

The claim is that this treatment is the only treatment that has been demonstrated to reduce fractures at ALL those key sites!

You may want to know that in May 2007 the New England Journal of Medicine reported that a study involving more than 7,700 women showed that treatment with this drug reduced the risk of spine fractures by 70% and hip fractures by 41%.

The reduction in spine fractures for the three years of the study was as follows: 60% in year one; 71% in year two and 70% in year three.  Again, those are significant numbers! - especially when we consider that bone loss in the spine can lead to kyphosis (or dowagers hump)  - a difficult and unsightly condition.

NOTE: A spokesperson for Novatis said the drug: " has shown significant efficacy in protecting women against fractures in all the common osteoporotic fracture sites, while demonstrating a favorable safety profile, It is our hope that this innovative once-yearly dosing regimen will have a positive impact on the management of this potentially devastating condition."

Novartis says that this medication:

   "is indicated for treatment of osteoporosis in postmenopausal women. In patients with a recent low-trauma hip fracture," It "reduces the incidence of new clinical fractures". And it:

  • "is indicated for treatment of osteoporosis in men at increased risk of fracture, including those with a recent low-trauma hip fracture."
  • "is indicated for treatment of osteoporosis associated with long-term systemic glucocorticoid therapy in postmenopausal women and in men with increased risk of fracture".
  • and finally, "Aclasta is indicated for the treatment of Paget's disease of the bone."

Many in the health care community believe that once a year infusions are an effective remedy for the main problem with daily, weekly or monthly medications. The problem with daily or even monthly medications is that many people just stop taking the medications for Osteopenia and Osteoporosis! (This failure to take one's medication called 'non-compliance' bythe medical community and non-compliance with pills for bone loss is high.)

Side effects Since this drug is sold under various names in different countries, the same side effects would apply  under its other name, Reclast. In fact, if you live in the United States, the Novartis site directs your to a  page about Reclast.

Novartis is careful to mention the possibility of Osetonecrosis with any of the bisphosphonates. They also state:

"Disturbances of mineral metabolism must be treated before starting therapy. Patients must be adequately supplemented with calcium and vitamin D. A single dose of Aclasta should not exceed 5 mg and infusion time should be no less than 15 minutes."

A study published in March of 2013, showed more serious side effects: Acute kidney injury. You can read a summary of that study by clicking this link to the Journal of Oncology Practice.
