What is Terbinafine?
Active Ingredients: Terbinafine
Terbinafine Tablets are an antifungal drug used in the treatment of fungal infections of the scalp, skin, and nails, including "jock itch" and "athlete's foot". The active ingredient is effective against fungi belonging to the group Onygenales and some Candida yeast, such as Candida glabrata.
Terbinafine belongs to a class of drugs known as allylamine antifungals. The active ingredient works by stopping squalene epoxidase, which inhibits ergosterol synthesis.

Combination of pulse therapy with terbinafine tablets and topical terbinafine cream for the treatment of dermatophyte onychomycosis: A pilot study
This pilot study evaluated the safety and effectiveness of pulse therapy using terbinafine tablets in 66 patients diagnosed with dermatophyte onychomycosis.
Each pulse consisted of oral terbinafine tablets (500mg/day) administered for one week followed by a three-week interval. Patients also received a topical 1% terbinafine cream that was applied daily. The number of pulses administered was determined based on the improvement observed in the affected nails and patient preference, with a maximum limit of six pulses. Efficacy was evaluated through clinical and mycological examinations conducted one year after initiating treatment.
Complete cure was noted in 51 patients (77.3%), improvements were seen in five patients (7.6%), and slight improvement in one patient (1.5%). Four patients (6.0%) showed no change in their condition.
The conclusion is that a combination of terbinafine pulse therapy with topical application of terbinafine cream led to safety and efficacy in this pilot study.
Terbinafine 250mg : Why the most common dosse?
Terbinafine 250mg is typically prescribed because it effectively treats fungal infections with a single daily dose. Lower doses, such as Terbinafine 125mg, require multiple doses per day or are more convenient for pediatric patients.
