A brand new examine suggests painkillers prescribed to pets may presumably be contributing to the opioid disaster within the U.S.

The examine, led by researchers on the College of Pennsylvania’s Perelman College of Drugs and the College of Veterinary Drugs, was printed Friday in Jama Community Open. It “reviewed all opioid tablets and patches allotted or prescribed for canine, cats, and different small animals” on the college’s college of veterinary medication from January 2007 to December 2017, a information launch on the findings mentioned.


Extra particularly, the researchers checked out 4 opioids —  tramadol, hydrocodone, codeine tablets and fentanyl patches — prescribed primarily to canine and cats and a small share to rabbits, snakes and birds.

Throughout this time, researchers discovered the “amount of those prescriptions, as measured in morphine milligram equivalents (MME), rose by 41 %,” whereas the variety of annual visits rose solely by 13 %.

“As we’re seeing the opioid epidemic press on, we’re figuring out different avenues of doable human consumption and misuse,” Jeanmarie Perrone, the examine’s senior creator, professor of emergency medication and the director of medical toxicology at Penn Drugs, mentioned in an announcement.

“Even the place the rise in prescribed veterinary opioids is nicely supposed by the veterinarian, it will possibly imply an elevated likelihood of leftover tablets being misused later by family members, offered or diverted, or endangering younger youngsters via unintentional publicity. The outcomes of this examine counsel that by assessing the speed of veterinary opioid prescriptions, we are able to develop methods to scale back each human and animal well being dangers related to growing use,” Perrone added.

In different phrases, the outcomes counsel “that the massive, growing quantity of opioids prescribed at one veterinary instructing hospital highlights considerations parallel to these about extreme opioid prescribing in people,” the examine states.

Some states, akin to Maine and Colorado, require veterinarians to look into the proprietor’s opioid prescription historical past earlier than they’ll write the prescription for his or her pet, whereas 20 states  “now require veterinarians to report their opioid prescriptions to a central database, simply as medical medical doctors do,” the information launch states.

“We discovered that the elevated amount of opioids prescribed by our hospital was not as a consequence of elevated affected person quantity alone. It’s possible that our purpose of guaranteeing our sufferers are pain-free post-operatively, notably for these requiring complicated and invasive procedures, has pushed our elevated prescribing practices throughout this era,” lead creator Dana Clarke, an assistant professor of interventional radiology on the College of Pennsylvania’s College of Veterinary Drugs, mentioned within the information launch.


That mentioned, “we don’t know the potential or extent of prescription diversion from animals to people, and what impression this might have on the human opioid disaster,” on the nationwide stage, Clarke famous.

In 2017, almost 70 % of the roughly 70,200 drug overdose deaths concerned an opioid, in keeping with the Heart for Illness Management and Prevention (CDC).  In the identical 12 months, the variety of overdose deaths that concerned an opioid was six occasions greater than in 1999.
