| To
avoid the risks of COX-2 inhibitors, our pharmacy
can compound topically applied NSAIDs such as
ibuprofen and ketoprofen. Topical NSAIDs have
a safety profile which is superior to oral formulations.
Topical NSAID administration offers the advantage
of local, enhanced delivery to painful sites with
a reduced incidence of systemic adverse effects.
Topical preparations
can be customized to contain a combination of
medications to meet the specific needs of each
patient.
Topical NSAIDs for Acute
Pain
“Topical non-steroidal
anti-inflammatory drugs have a lower incidence
of gastrointestinal adverse effects than the same
drugs when they are taken orally. The low incidence
of systemic adverse effects for topical NSAIDs
probably results from the much lower plasma concentration
from similar doses applied topically to those
administered orally. Topical application of ibuprofen
resulted in measurable tissue concentrations in
deep tissue compartments, more than enough to
inhibit inflammatory enzymes.”1 Topical
NSAIDs have not been associated with renal failure.2

The following article reports “The systemic
concentrations of ketoprofen have also been found
to be 100 fold lower compared to tissue concentrations
below the application site in patients undergoing
knee joint surgery. Topically applied ketoprofen
thus provides high local concentration below the
site of application but lower systemic exposure.”
