Usage
- This combination medication is prescribed for the topical relief of pain and inflammation associated with musculoskeletal and joint disorders such as sprains, strains, arthritis (including osteoarthritis and rheumatoid arthritis), low back pain, and sports injuries.
- Pharmacological Classification: Topical analgesic, non-steroidal anti-inflammatory drug (NSAID), counterirritant.
- Mechanism of Action: This combination exerts its effects through multiple pathways. Aceclofenac, an NSAID, inhibits cyclooxygenase (COX) enzymes, reducing the production of prostaglandins, which are mediators of pain and inflammation. Methyl salicylate, another analgesic, acts as a counterirritant, producing a warming sensation and potentially inhibiting COX enzymes. Capsaicin, derived from chili peppers, initially stimulates and then desensitizes pain receptors by depleting substance P, a neurotransmitter involved in pain transmission. Menthol provides a cooling sensation by activating TRPM8 receptors, which can mask pain perception and dilate blood vessels, enhancing drug penetration.
Alternate Names
While there isn’t a universally recognized alternate name for this specific combination, it is sometimes referred to as a topical analgesic or counterirritant. Brand names vary depending on the manufacturer and region. Nicoace is one brand name, but others are likely available.
How It Works
- Pharmacodynamics: Aceclofenac reduces pain and inflammation by inhibiting COX enzymes. Capsaicin desensitizes peripheral nociceptors, reducing pain signal transmission. Menthol and methyl salicylate produce cooling and warming sensations respectively, acting as counterirritants.
- Pharmacokinetics: Primarily applied topically, absorption through the skin leads to localized rather than systemic effects. Some systemic absorption of aceclofenac and methyl salicylate can occur, with hepatic metabolism and renal excretion. Capsaicin and menthol are minimally absorbed systemically.
- Mode of Action: Aceclofenac inhibits COX-1 and COX-2 enzymes, reducing prostaglandin synthesis. Capsaicin depletes substance P from sensory neurons. Menthol activates TRPM8 receptors. Methyl salicylate acts as a counterirritant and may also inhibit COX enzymes.
- Elimination Pathways: Primarily hepatic metabolism and renal excretion for aceclofenac and methyl salicylate. Limited systemic absorption and elimination information is available for capsaicin and menthol used topically.
Dosage
Standard Dosage
Adults:
Apply a thin layer to the affected area 3-4 times daily.
