Please do not use Wikipedia for affiliate marketing, such as you did in the article Buprenorphine. This is contrary to the guidelines on external links and immediately suggests that you may have a conflict of interest. Feel free to take a look at the five pillars of Wikipedia policy to learn more about this project and how you can make a positive impact. Thank you. Egg  Centri  c  22:33, 20 May 2012 (UTC)

Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
