There
has always been a tendency or desire for ‘magic wand’ therapy
throughout the population and veterinarians are no exception.
Dramatic results from some treatments, such as i/v administration
of calcium in downer cows, only add to this air of mystique.
It is a natural human tendency to prefer simple solutions
to problems and neither clinicians nor clients desire matters
to more complicated than they expect.
A classic example is the above-mentioned calcium for downer
cows. Because it was such an efficient and rapid ‘fire brigade
remedy’, it took some time to convince both veterinarians
and farmers that the situation was more complicated than that,
mainly because they did not want it to be so.

The
acceptance of DCAD has gone a long way towards showing that
acidogenic treatments benefit hypocalcaemia, despite being
not indicated in ketosis. Similarly in small animal medicine
the plethora of NSAIDs and the over reliance on COX inhibition,
now shown to not be the simple explanation originally mooted,
has clouded the issue. Practitioners try and rationalize the
range but it is simply a case of no size fits all. Some well
established drugs for long-term use simply are not at the
top of the range for acute injuries and many also have too
narrow a therapeutic window for long-term use in cats.
The
best analogy would be antibiotic usage, where the drug is
tailored to the pathogenesis or, to use the old farriers’
adage, “fit the shoe to the horse, not the horse to the shoe.”

Palliative
therapy is certainly less demanding than curative therapy
in this respect and this is graphically expressed in cardiac
therapy. ACE inhibition is a simple procedure for reducing
load by reducing both blood pressure and blood volume in a
one step inhibition.
It
can be a dramatic , perhaps the closest we have to the Harry
Potter concept, but it is still not magic as, like all palliative
therapy, it treats the symptom and not the cause.
