Purdue Resubmits Butrans Petition to FDA
Purdue Pharma has resubmitted its 3/27 petition asking FDA to place specific restrictions on follow-on products citing its Butrans (buprenorphine) transdermal system for transdermal administration as the reference-listed drug. The company says the requirements are necessary to ensure that any follow-on products are as safe and effective as Butrans. The resubmission says that representatives of the FDA Office of Regulatory Policy asked that it be turned in.
