| Transdermal
therapy to decrease side effects
Medications that relieve pain, reduce inflammation,
and relax muscles can have side effects that are
detrimental to athletic performance, such as drowsiness.
However, when these medications are administered
transdermally, the therapeutic benefit can be
enhanced while significantly reducing the risk
of adverse effects.
For example, research has shown that topically
applied ketoprofen provides a high local concentration
of drug below the site of application but decreases
systemic exposure and significantly reduces the
risk of gastrointestinal upset or bleeding. When
properly compounded into an appropriate base,
tissue concentrations of ketoprofen were found
to be 100-fold greater below the application site
(knee) compared to systemic concentrations. Muscle
relaxants can be similarly prepared to minimize
the risk of drowsiness. |
