Menthol-Based Topical Analgesic Induces Similar Upper and Lower Body Pain Pressure Threshold Values: A Randomized
Journal of Sport Rehabilitation
|September 23, 2021
Summary
Menthol topical analgesics effectively reduce pain sensitivity in both upper and lower body muscles and tendons. This study found no significant differences in pain reduction effectiveness based on application location.
Area of Science:
- Sports Medicine
- Pain Management
- Dermatology
Background:
- Menthol-based topical analgesics are widely used for pain relief in musculoskeletal conditions.
- Limited research exists on the comparative effectiveness of these analgesics across different body regions.
Purpose of the Study:
- To investigate potential differences in pain pressure threshold (PPT) and pain attenuation using a menthol topical analgesic.
- To compare effectiveness across various upper and lower body muscles and tendons.
Main Methods:
- A randomized controlled intervention study involving 16 participants.
- PPT was measured before and 15 minutes after applying a menthol-based topical analgesic.
- Testing included upper body (deltoid, biceps, epicondylar tendon) and lower body (quadriceps, hamstrings, gastrocnemius, erector spinae, patellar, Achilles) sites.
Main Results:
- The menthol analgesic significantly increased PPT, indicating reduced pain sensitivity (11.6% increase, P = .05).
- Pain sensitivity was significantly lower in lower body locations compared to upper body locations (31.5%-44.2% higher PPT, P < .0001).
Conclusions:
- Menthol-based topical analgesics provide consistent pain relief across different body areas.
- Consumers and health professionals can rely on these analgesics for effective pain reduction regardless of application site.

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
533
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

01:23Local Anesthetics: Common Agents and Their Applications
625
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
