How Do Pain Relieving Patches Work? The Science Explained
Pain relieving patches provide localized analgesic effects through sustained transdermal medication delivery. Understanding the underlying mechanisms of action can promote proper use.
01. Penetration of skin by medications
Ingredients like diclofenac, lidocaine and capsaicin penetrate the skin reaching nerves and tissues.
02. Blocking pain signal transmission
Medications short-circuit pain signals to the brain to reduce localized discomfort.
03. Anti-inflammatory effects
NSAID ingredients inhibit production of inflammation-causing substances linked to pain.
04. Increased local blood flow
Counterirritants like menthol, camphor induce vasodilation and circulation to the area diminishing pain.
05. Duration of effect
Pain relief persists for 8-12 hours or longer depending on patch ingredients and dosage. Patches then require replacement.
Recognizing how pain relieving patches work biochemically allows optimizing placement and realistic expectations of benefits.
