| Pain management
is essential because, even when the underlying
disease process is stable, uncontrolled pain prevents
patients from working productively, enjoying recreation,
or taking pleasure in their usual roles in the
family and society. Chronic pain may have a myriad
of causes and perpetuating factors, and therefore
can be much more difficult to manage than acute
pain, requiring a multidisciplinary approach and
customized treatment protocols to meet the specific
needs of each patient.
Optimal treatment may involve the use of medications
that possess pain-relieving properties, including
some antidepressants, anticonvulsants, antiarrhythmics,
anesthetics, antiviral agents, and NMDA (N-methyl-D-aspartate)
antagonists. NMDA-receptor antagonists, such as
dextromethorphan and ketamine, can block pain
transmission in dorsal horn spinal neurons, reduce
nociception, and decrease tolerance to and the
need for opioid analgesics. [Anesth Analg 2001
Mar;92(3):739-44] By combining various agents
which utilize different mechanisms to alter the
sensation of pain, physicians have found that
smaller concentrations of each medication can
be used.
Topical and transdermal creams and gels can be
formulated to provide high local concentrations
at the site of application (e.g., NSAIDs for joint
pain), for trigger point application (e.g., combinations
of medications for neuropathic pain), or in a
base that will allow systemic absorption. Side
effects associated with oral administration can
often be avoided when medications are used topically.
Studies suggest that there are no great restrictions
on the type of drug that can be incorporated into
a properly compounded transdermal gel. When
medications are administered transdermally, they
are not absorbed through the gastrointestinal
system and do not undergo first-pass hepatic metabolism.
We work together with prescriber and patient
to solve problems by customizing medications that
meet the specific needs of each individual. Please
contact our compounding pharmacist to discuss
the dosage form, strength, and medication or combination
that is most appropriate for your patient. |
