Hi Dorri,
The second drug your to which your doctor was referring was probably zoledronate. Trade name is Zometa. It's not a new drug here (I'm in the USA)... they've been using it for years on cancer patients. What IS new is federal approval of it for treatment of osteoporosis. You can do a search on this board for Zometa. There are quite a few threads that talk about it.
A few things you need to know about it:
1) It is a biphosphonate like Fosamax and Actonel. It prohibits resorption of bone and does not actually create new bone.
2) It's not a pill or injection; it's administered intravenously for about 15 minutes every few months.
3) Some people have problems with it, like flu symptoms. Also osteonecrosis of the jaw is common enough that they recommend you NOT schedule any oral surgery when on Zometa treatment. Healing from a procedure as simple as a tooth extraction can be compromised.
4) It's very expensive...something like $800-up for one 4 mg dose.

I'm not sure what the process is for you in Canada. I had to get pre-approval from my insurance company. They approved it but I decided against it (for now) after all my research.
As for the strontium ranelate...I'm very excited about that one.

It not only slows bone loss but also builds new bone. Right now I don't think you can get it in Canada. It's sold in Europe under the name Protelos. You might be able to get strontium citrate, though I don't know whether it works as well as the strontium ranelate.
