BRISTOL, Tenn.--(BUSINESS WIRE)--Results from a randomized study with Zyclara following cryotherapy in the treatment of actinic keratoses (AK) demonstrated Zyclara complemented the effectiveness of cryosurgery in reducing total AK count and achieving complete clearance of AK, according to data presented at the American Academy of Dermatology Summer Academy Meeting 2010 (Summer AAD), August 4 – 8. The study found that Zyclara used after cryosurgery produced greater lesion reduction than cryosurgery alone across all measures including doubling the proportion of patients with complete clearance from 30 percent to 60 percent in the cryosurgery-treated area.
