Caretta Therapeutics is introducing Venodol, a nonaddictive alternative to opioid and steroidal analgesics for patients with moderate to severe chronic pain associated with inflammation. Indications for Venodol include joint pain, inflammatory arthritis pain, tendinitis, and stubborn aches. With cobra venom as its active ingredient, the easy-to-use analgesic roll-on does not contain acetaminophen, aspirin, naproxen sodium, or ibuprofen. Venodol users are instructed to apply the analgesic to the affected area three to four times per day for up to two weeks. A 2-oz topical roll-on applicator sells for $19.95.
