Premarin, the top
selling hormone replacement therapy (HRT) for menopausal women, is made from pregnant
mares' urine (PMU). Estrogen is extracted from the urine and is sold in many different
forms to help with the symptoms of menopause. Approximately 9 million women are
currently taking some form of Premarin and that number is expected to rise due
to aging baby boomers. Premarin, made by Wyeth-Ayerst Laboratories, a subsidiary
of American Home Products, is the only human estrogen replacement drug that is
derived from animal products, most others are derived from soy and vegetables.
The patent on Premarin, owned by Wyeth-Ayerst, is about to expire. This may well
result in the manufacture of an array of generic substitutes, and is likely to
increase the number of horses used in this industry.
Pregnant horses are
four legged drug machines-being repeatedly impregnated and confined to narrow
stalls as their urine is collected. Horses are kept inside for 6 months out of
the year. The horses are housed in cramped stalls 8'x 3 1/2'x5'. Horses are hooked
up to a urine collection bag that is fixed into position just below their tail.
These urine collection devises (UCDs) are painful and unhygienic. Urine soaks
the skin of the vulva and can cause severe infection and painful lesions. The
horses are tied with a short rope to keep them from taking more then a single
step in either direction, or from lying down. After several years on line, the
mares are shipped to slaughterhouses where they are butchered so their meat can
be exported to Europe or Japan for human consumption.
Today, there are
439 PMU farms still in existence. The majority are in Canada and a few are in
North Dakota. In 1999 there were about 55, 000 to 65,000 mares on the "pee
lines". Guidelines state that horses should be offered water no less then
two times per day. However, PMU farmers prefer to water as little as possible
to keep the concentration of estrogen in the urine high. They are paid based on
the concentration not the volume of urine collected.
Every spring, each
mare gives birth to a foal. These foals spend the first few months with their
mothers and then are rounded up in September to allow their mothers to rejoin
the lines. Most of these young horses are then taken to feed lots were they are
fattened up and sold for slaughter. The meat is then exported to European and
Asian markets for human consumption.
Ollie Bracken a retired Manitoba,
Canada PMU farmer, stated in a 1995 interview that he retired from PMU farming
because, "When you have to see a colt being born and then have to destroy
it, it's rough because they're just babies. I just don't think it was right to
continue what I was doing."
According to a former PMU farmer from New
York, "piss farms," as he called them, were located in New York and
Vermont in the early 50s. Urine was collected by Wyeth-Ayerst, a subsidiary of
American Home Products in Philadelphia, and taken to Montreal where it was processed
into a powdered form and then shipped back to New York to be made into tablets
and marketed
Most of the media attention regarding PMU farms has focused
primarily on the mass production and slaughter of the foals born to the tens of
thousands of mare annually. The heightened European demand for horse meat, due
to the effects of mad cow and hoof-and-mouth disease has resulted in a dramatic
increase in the number of horses slaughtered, and has caused the price of horse
meat to go up.
COMMENTS BY BARBARA SEAMAN, C0-FOUNDER OF THE NATIONAL
WOMEN'S HEALTH NETWORK: Premarin, the most popular variety of hormone replacement
therapy, was approved as a menopause treatment by the FDA on May 8, 1942. From
1991 to 1999, it was the best selling drug in the United States. It is now number
three, behind Synthroid and Lipitor.
The relationship between Premarin and
animal rights presents a valuable model of how industry interests protect themselves
on a grand scale without regard to community well being. In her article, "Pissing
their Lives Away," Susan Wagner writes about how Wyeth-Ayerst, the manufacturer
of Premarin, has been exploiting and abusing horses for sixty years. Not just
a clever name, Premarin is made from PREgnant MARes urINe. While Wagner raises
compelling points about the issue of animal abuse, perhaps the most revealing
drug company strategy discussed involves Wyeth-Ayerst's successful blockage of
the approval of generic Premarin.
When a drug is approved, drug companies
are granted a patent for a limited number of years before other, often smaller,
companies are allowed to develop and market generic versions. By the mid 1990's,
the patent on Premarin had sat in expiration for more than 25 years. In 1997,
a company called Duramed pharmaceuticals applied for approval of a generic, soy-based,
non-animal version of Premarin called Cenestin. Previous to this application,
the only condition for generic approval was identical active ingredients. A massive
political battle ensued, with Wyeth-Ayerst exerting considerable financial pressure
on powerful forces in Washington to intervene on their behalf. The result was
the establishment of new, more ambiguous standards for generic drugs, in which
testing for total active chemical similarity became the new measuring stick. Since,
in 50 years, not all the chemicals in Premarin had been adequately clarified,
it would be difficult to determine generic "bio-equivalency." In rejecting
Duramed's application, the FDA specifically sited the absence of a chemical called
DHES as essential to their conclusions. Previously qualified as an "impurity,"
DHES was a little understood, animal specific element present in Premarin. Because
the role of DHES in Premarin had not been documented, and Cenestin did not contain
DHES, FDA argued that generic approval would be impossible, despite the total
lack of evidence that DHES has any active properties. Cenestin was approved shortly
after as a new drug rather than a generic.
This outrageous triumph of economic
and political influence over patient interests is typical of the tactics employed
by drug companies to protect and promote their top selling drugs. A generic, non-animal
Premarin would be a great thing for HRT consumers. It would provide a lower priced
drug for the same results. It would also begin the important process of converting
to the consumption of non-animal estrogens. Women continue to pay high prices
(around $300 a year), and horses continue to suffer, so that Wyeth Ayerst can
continue to reap maximum benefits from a drug that for much of its sixty year
history has been one of the top ten drugs in the United States.
Given the
new consensus in the scientific community that neither animal nor plant based
estrogen may be a healthy choice, perhaps 2002 will prove to be the year when
the tide of the estrogen sea turns. If so, perhaps the history of HRT will serve
as a model for exposing and controlling corrupt drug company policies. It is a
story waiting patiently but imperatively to be told.
