The only therapeutic use for which cantharidin is currently primarily indicated for is as an active ingredient in topical agents for treating common warts (verruca vulgaris), periungual warts, plantar warts, and molluscum contagiosum. At the same time, such topical cantharidin applications have also been used for a number of off-label indications like callus removal, cutaneous leishmaniasis, herpes zoster, and acquired perforating dermatosis. Furthermore, since most topical cantharidin applications are most commonly available in a 0.7% formulation or a more potent 1% mixture, the 0.7% formulation is most commonly indicated for the treatment of common warts, periungual warts, and molluscum contagiosum while the more potent 1% mixture is typically limited only for use by healthcare professionals in a clinical setting for treating plantar warts and other more specialized off-label conditions. Moreover, there have also been studies into whether or not cantharidin could be effective at being used as an inflammatory model or in cancer treatment - either of which has yet to formally elucidate any results.
Cantharidin is a natural toxin produced by the blistering beetle that possesses both vesicant (blistering) and keratolytic effects. The substance elicits these effects by inducing acantholysis (loss of intercellular connections) through the targeting of the desmosomal dense plaque, resulting in the detachment of the desmosomes from the tonofilaments. Cantharidin's effectiveness against warts is proposed to be a result of the exfoliation of the wart body as a consequence of the compound's acantholytic action. This acantholytic action generally does not go beyond the epidermal cells so that the basal layer remains intact and minimal effect occurs on the corium. There is consequently no scarring from the topical application of cantharidin.
Irritants
Drugs that act locally on cutaneous or mucosal surfaces to produce inflammation; those that cause redness due to hyperemia are rubefacients; those that raise blisters are vesicants and those that penetrate sebaceous glands and cause abscesses are pustulants; tear gases and mustard gases are also irritants. (See all compounds classified as Irritants.)
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)
Absorption
Cantharidin is absorbed from the gastrointestinal tract, and, to a limited extent from the skin as well. Little pharmacodynamic and pharmacokinetic data regarding cantharidin in the human body currently exists; recruitment for First-Time-In-Human clinical trials regarding such information have been ongoing in 2018. There are however some studies regarding such data in animal models like beagle dogs.
Route of Elimination
It has been observed that absorbed cantharidin is excreted by the kidney. Little pharmacodynamic and pharmacokinetic data regarding cantharidin in the human body currently exists; recruitment for First-Time-In-Human clinical trials regarding such information have been ongoing in 2018. There are however some studies regarding such data in animal models like beagle dogs.
Volume of Distribution
After oral or IP injection of (3)H-labeled cantharidin, high levels of radioactivity distributed to and were exhibited in the bile, kidney, liver, stomach, and tumor cells of ascites hepatoma-bearing mice. Such distribution suggests the agent has an affinity for liver and tumor tissues. Little pharmacodynamic and pharmacokinetic data regarding cantharidin in the human body currently exists; recruitment for First-Time-In-Human clinical trials regarding such information have been ongoing in 2018. There are however some studies regarding such data in animal models like beagle dogs.
Clearance
Little pharmacodynamic and pharmacokinetic data regarding cantharidin in the human body currently exists; recruitment for First-Time-In-Human clinical trials regarding such information have been ongoing in 2018. There are however some studies regarding such data in animal models like beagle dogs.

Cantharidin is specifically absorbed by lipids in the membrane of epidermal keratinocytes, where it activates the release of neutral serine proteases. These enzymes subsequently break the peptide bonds in surrounding proteins, leading to the progressive degeneration of desmosomal dense plaques, which are important cellular structures that participate in cell-to-cell adhesion. Such degeneration results in the detachment of the tonofilaments that hold cells together. This process as a whole leads to the selective acantholysis (loss of cellular connections) and blistering of the skin when the cantharidin topical application is applied upon specific topical developments like warts. A blister(s) at the application site develop within 24 to 48 hours of application and typically resolve within 4 to 7 days. Factors that can modify this proposed time frame include the volume or concentration of cantharidin used, physical contact time of the applied compound (usually between 4 to 24 hours), the presence of any occlusive dressings, or even patient sensitivity to cantharidin. The blistered lesions ultimately heal without scarring. Finally, there are some studies that suggest cantharidin's chemical profile as a potent and selective inhibitor of protein phosphatase 2A confers upon it an oxidative stress-independent growth inhibition of pancreatic cancer cells through cancer cell-cycle arrest and apoptosis. Nevertheless, the fact that little data regarding the pharmacodynamics and pharmacokinetics of cantharidin in the human body exists and certain toxic effects of cantharidin that have been observed following oral ingestion in humans like ulceration of the gastrointestinal and genitourinary tracts, along with electrolyte and renal function disturbance are strong reasons as to why the compound currently lacks FDA approval is used fairly limitedly for formal therapeutic indications.
Cantharidine totally inhibits the phosphorylase a phosphatase activity in mouse liver, muscle, and skin cytosol at 5000 nM, with IC50s of 110-250 nM. About 50% of the phosphorylase a phosphatase activity of brain cytosol is sensitive to cantharidine with an IC50 of approximately 80 nM and the remaining half is not inhibited even at 5000 nM.
