Description

Tavaborole is a boron-based pharmaceutical agent indicated for the topical treatment of toenail onychomycosis, a fungal infection of the nail and nail bed due to Trichophyton rubrum or Trichophyton mentagrophytes infection. Tavaborole acts by inhibiting an aminoacyl-transfer ribonucleic acid (tRNA) synthetase (AARS) - Leucyl-tRNA synthetase. Leucyl-tRNA synthetase is an essential fungal enzyme required for protein synthesis and for the catalysis of ATP-dependent ligation of L-leucine to tRNA(Leu). Tavaborole’s low molecular weight (approximately half of most antifungals, such as terbinafine and efinaconazole) permits optimal nail plate penetration, superior to that of existing topical antifungal medications.

Sample Use Guides

In Vivo Use Guide
Tavaborole 5% topical solution (each milliliter of solution contains 43.5 mg of tavaborole) should be applyed to affected toenails once daily for 48 weeks. It should be applied to the entire toenail surface and under the tip of each toenail being treated (for topical use only and not for oral, ophthalmic, or intravaginal use).
Route of Administration: Topical
In Vitro Use Guide
Tavaborole demonstrated minimum inhibitory concentration (MIC) values ranging from 0.25–2 μg/mL against all fungi tested; addition of 5% keratin powder did not affect the MIC against T rubrum. The minimum fungicidal concentration (MFC) values for tavaborole against T rubrum and T mentagrophytes were 8 and 16 μg/mL, respectively.
