Medicated skin patches for pain relief are available for short-term as well aschronic pain, and when used properly can offer significant pain relief.Pain relief patches are a popular choice for people who cannot tolerate oral medication because of stomach irritation, ulcers or other reasons.
The pain relief plaster come in several strengths, containing different amounts of fentanyl. Dosage is indicated in micrograms (mcg) delivered through the skin—from 12.5 to 100 mcg per hour. This is both helpful, as we can use a patch on virtually any size dog, and convenient, since patches cannot be cut down (the liquid fentanyl would leak out of its container).
Manufacturing a patch is more complicated and therefore more expensive than making a pill, says Phil Nixon of Pfizer's Pharmaceutical Sciences Technology & Innovation division in Groton, Conn.
Patches also must be disposed of out of the reach of pets and children, because they still have medication on them, says Smalling's doctor, Scott Zashin, a clinical professor of medicine at the University of Texas-Southwestern Medical School.
The pain relief plaster is applied to shaved skin, and after a 12- to 24-hour delay, it begins to slowly and steadily deliver the medication through the skin and into the bloodstream. This delay allows us to put the patch on a dog the day before surgery so that it kicks in soon after the end of the procedure. If that isn’t possible, other drugs are used until the patch starts working.
