| 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. Palliative care often involves the
use of opioid analgesics. 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. |
