Open the CIPO recordAbstract From the Canadian patent
The invention relates to a preparation for restenosis prevention. The preparations for restenosis prevention known as yet do not reach sufficient active agent concentrations in the affected sections of the vascular walls as higher doses cause undesirable side effects. A preparation is provided which contains at least one lipophilic antinyperplastic having a distribution ratio between butanol and water 0.5, together with a vascular contrast agent for enhancing artery/vein imaging. The lipophilic active agent is absorbed by the vascular wall fast and in sufficient quantity. The preparation may be a liquid. The preparation may also be applied to a catheter.

Why it's free to use
- Filed December 20, 2001 and granted May 27, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 20, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
