Terbinafine hydrochloride is a broad-spectrum antifungal drug of the allylamine class, which inhibits the activity of squalene epoxidase in the fungal cell membrane, affecting the generation of the fungal cell membrane and leading to an excessive accumulation of squalene, thereby exerting a fungistatic and fungicidal effect. It has inhibitory and lethal effects on a variety of fungi, such as Microsporum canis, Trichophyton gypseum, and Trichophyton mentagrophytes, and also has a strong lethal or fungistatic effect on Malassezia and Candida.
The characteristic of terbinafine hydrochloride is its dual mechanism of action, which can both kill fungi and inhibit fungal growth. It is rapidly absorbed in the body and has lipophilic and keratophilic properties, which allow it to quickly reach all parts of the body to achieve an effective therapeutic effect. In addition, terbinafine hydrochloride has a high safety profile, and no significant abnormalities have been observed even when used at five times the recommended dose for 28 days.
In veterinary medicine, terbinafine hydrochloride is commonly used to treat fungal infections in dogs and cats, such as dermatophytosis. It is available in the form of oral medication, which has the advantages of convenient administration, good palatability, and significant therapeutic effect. For example, Han Te Fen (terbinafine hydrochloride tablets) is an orally administered antifungal drug specifically designed for dogs, with characteristics of broad-spectrum eradication, deep antifungal action, significant efficacy, safety and reliability, and dog friendliness.
It is important to note that although terbinafine hydrochloride has a good therapeutic effect on fungal infections, overdose may cause adverse reactions in pets. Therefore, it should be administered strictly according to the instructions or the advice of a veterinarian. If pets accidentally lick topical medications containing terbinafine hydrochloride, it may cause some discomfort, such as blackening of the tongue or drooling, but a small amount of licking usually does not pose a serious threat to the health of pets. If pets show severe symptoms, a veterinarian should be contacted for treatment in a timely manner.
