It was approved for medical use in the United States in July 2023.[1][7][8][9] The USFood and Drug Administration (FDA) considers it to be afirst-in-class medication.[10]

Lotilaner is a member of theisoxazoline family of compounds.

Medical uses

[edit]

Lotilaner isindicated for the treatment ofDemodex blepharitis.[1] It had been first used in veterinary medicine against fleas and ticks, and later for Demodex mites.[11]

Veterinary uses

[edit]

Lotilaner, sold under the brand nameCredelio among others, is aveterinary medication used to control fleas and ticks in dogs and cats.[2][3][4][12] It is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis) and for the treatment and control of tick infestations includinglone star tick (Amblyomma americanum),American dog tick (Dermacentor variabilis),black-legged tick (Ixodes scapularis), andbrown dog tick (Rhipicephalus sanguineus).[13] It is takenby mouth.[2][3]

Lotilaner in combination withmilbemycin oxime is sold under the brand name Credelio Plus.[14] It is used in dogs to treat concurrent infestations with parasites living outside (ticks and/or fleas) and inside (worms) the animal's body.[14]

Lotilaner (brand Lotimax) is used for the treatment of flea, tick, and mite infestations in dogs, including treatment ofdemodicosis (caused byDemodex canis).[15]

Mechanism of action

[edit]

Lotilaner paralyzes and kills parasites by interfering with the way that signals are passed between their nerve cells.[11]

Lotilaner is a gamma-aminobutyric acid (GABA)-gated chloride channel inhibitor selective for arthropods. Inhibition of these GABA chloride channels causes a paralytic action in the target organism leading to its death. Lotilaner is not an inhibitor of mammalian GABA mediated chloride channels when tested at up to 30 µM (18 µg/mL)in vitro (approximately 1100 times the RHOD).[16]

Legal status

[edit]

In March 2024, the Committee for Veterinary Medicinal Products (CVMP) of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the veterinary medicinal product Lotimax, Chewable tablet, intended for use in dogs.[5] The applicant for this veterinary medicinal product is Elanco GmbH.[5] Lotimax was approved for medical use in the European Union in April 2024.[15]

Research

[edit]

Tarsus Pharmaceuticals has conductedphase II studies of lotilaner as a remedy to preventtick bites in humans.[17][11]
