About Arimideks

In 1997 aromatase inhibitors letrozole and arimideks which was more effective remedy for prevention of recurrence of a breast cancer, in comparison with Tamoxifenum which is "the gold standard" among drugs passed clinical tests.

This drug increases survival level to 63% in comparison with therapy by Tamoxifenum. The risk of recurrence of tumors decreases by 32%. It is convenient in use that is noted in responses, and causes side effects in comparison with inhibitors of aromatase of the previous generations much less often. Use of this drug during 5 flyings was more effective, than use of Tamoxifenum during the same time. Besides, transition to it after 2 flyings of reception of Tamoxifenum is more effective too if to compare to reception of one Tamoxifenum within 5 years and such transition is justified. But, in comparison with Tamoxifenum, it causes undesirable reactions in the form of osteoporosis, joint pains and pathological changes more often.

All these moments reflect About Arimideks:

  • "… Awfully transferred — bones and joints therefore moved with a stick hurt, inflow of heat and perspiration tormented";
  • "… Transferred to reception of this drug after Tamoxifenum as it was inefficient in my case";
  • "… I had such scheme: Tamoxifenum 3 years, then aromatase inhibitors";
  • "… I can tell nothing bad about Tamoxifenum as accepted it 5 years, then transferred to aromatase inhibitors which 5 years are going to accept too".

Many note good tolerance of drug for many years. For some it was unacceptable.

There is an opinion that Arimideks is more effective than Femara though researches were not conducted.

According to oncologists, Zoladeks and Arimideks's use in a combination gives lasting effect in certain cases for years.

Efficiency of a combination of Arimideks and Faslodeks is studied.

The combination to Tamoxifenum is not applied as it does not lead to efficiency increase, and expressiveness of side reactions amplifies.
