Pfizer Expected to Increase PMU Production

Pfizer Canada has announced it will increase the amount of pregnant mare urine (PMU) it collects from its facilities in the Canadian provinces of Manitoba and Saskatchewan in 2016 and 2017.

Pfizer uses PMU to manufacture the hormone replacement therapy drug Premarin, used to treat symptoms of menopause and prevent osteoporosis in post-menopausal women.

According to the Manitoba Co-operator, this is thought to be the first time Pfizer has increased the volume of PMU since it bought the previous Premarin manufacturer, Wyeth Inc., in 2009.

“We can confirm that Pfizer will be increasing our pregnant mare urine (PMU) operations from 2016–2017. It will be a small increase over the current amount that we contract,” wrote Pfizer Canada’s corporate affairs manager Christina Antoniou in an email to Horse Collaborative.

So far, there are no details on how much more urine will be collected, or how many horses will be impacted. According to the North American Equine Ranching Information Council there are currently 19 PMU ranches in Manitoba and Saskatchewan, and 1,300 mares producing urine.

    What a freaking nightmare for these poor mares and resultant foals. Lord help them.

    My own doctor didn’t have a clue that Premarin was made this way, nor did she know that there is a safer synthetic version.

    Thank you so much for sharing this. As ugly as this news is, we’ve got to make people aware.
