Indications

• Topical pain relief
• Muscle aches
• Joint pain
• Inflammation

Dosage

Children: For children, the

Adults: For topical application, camphor is usually applied as needed to the affected area, following the instructions on the specific product used. Consult the product label or a healthcare professional for detailed dosing guidelines.

Mechanism of action

Camphor activates the transient receptor potential vanilloid 1 (TRPV1) and TRPV3 channels, which are involved in sensing pain and temperature. It requires higher concentrations to activate TRPV1 compared to capsaicin but notably desensitizes TRPV1 more rapidly and completely. This action is enhanced under inflamed conditions through phospholipase C-coupled receptor stimulation. The distinct activation pathways of camphor contribute to its analgesic effects, making it effective in reducing pain sensitivity.

Pharmacodynamics

The pharmacodynamic properties of camphor are primarily related to its interaction with TRPV1 and TRPV3 channels. By activating these receptors, camphor induces a sensation of warmth and can result in analgesia through sensory nerve excitation and subsequent desensitization. This mechanism is similar to that of other topical analgesics like capsaicin and menthol but is characterized by a faster desensitization of TRPV1. Additionally, camphor's effects may include local vasodilation and increased blood flow to the area of application, which can further alleviate pain and inflammation.

Pharmacokinetics

Camphor is absorbed through the skin when applied topically. Its pharmacokinetic profile involves distribution to various tissues, where it can exert local effects. The metabolism of camphor occurs primarily in the liver, and it is eliminated from the body mainly through urine. The onset of action is typically rapid due to its topical application, and the duration of effect may vary depending on the formulation and concentration used.

Mechanism of action

Camphor is a naturally occurring compound that is used as a major active ingredient of balms and liniments supplied as topical analgesics. ... Capsaicin and menthol, two other topically applied agents widely used for similar purposes, are known to excite and desensitize sensory nerves by acting on two members of transient receptor potential (TRP) channel superfamily: heat-sensitive TRP vanilloid subtype 1 (TRPV1) and cold-sensitive TRP channel M8, respectively. Camphor has recently been shown to activate TRPV3, and here /investigators/ show that camphor also activates heterologously expressed TRPV1, requiring higher concentrations than capsaicin. Activation was enhanced by phospholipase C-coupled receptor stimulation mimicking inflamed conditions. Similar camphor-activated TRPV1-like currents were observed in isolated rat DRG neurons and were strongly potentiated after activation of protein kinase C with phorbol-12-myristate-13-acetate. Camphor activation of rat TRPV1 was mediated by distinct channel regions from capsaicin, as indicated by camphor activation in the presence of the competitive inhibitor capsazepine and in a capsaicin-insensitive point mutant. Camphor did not activate the capsaicin-insensitive chicken TRPV1. TRPV1 desensitization is believed to contribute to the analgesic actions of capsaicin. /The authors/ found that, although camphor activates TRPV1 less effectively, camphor application desensitized TRPV1 more rapidly and completely than capsaicin. Conversely, TRPV3 current sensitized after repeated camphor applications, which is inconsistent with the analgesic role of camphor. /Investigators/ also found that camphor inhibited several other related TRP channels, including ankyrin-repeat TRP 1 (TRPA1). The camphor-induced desensitization of TRPV1 and block of TRPA1 may underlie the analgesic effects of camphor.
