Terbinafine 250 mg

Terbinafine Tablet is a strong medicine and a type of medication known as antifungals. It is available in tablet form and is utilized to cure many fungal infections of the scalp, body, groin, feet, fingernails, and toenails. This prescription tablet attacks fungal infections at their roots, so it is very effective in fighting off chronic fungal growth.

It's worth mentioning that terbinafine is not effective on infections caused by viruses or bacteria. 

The medicine takes effect by killing the fungus causing the infection, thereby allowing normal skin and nails to return.

Uses of Terbinafine

Terbinafine tablets affect a broad variety of fungal infections, including:

• Onychomycosis (fungal infection of the toenails or fingernails)
• Jock itch
• Athlete's foot
• Tinea corporis (ringworm of the body)

It's important to mention that terbinafine only treats fungal infections and not bacterial or viral ones.

How Terbinafine Tablet Works

• Terbinafine Tablet is an allylamine antifungal that inhibits the synthesis of ergosterol in fungal infections. It inhibits the enzyme squalene epoxidase, which is critical in the formation of the fungal cell wall. Inhibition causes the reduction of ergosterol and the accumulation of squalene, making the fungal cell wall weaker.
• The drug is extremely lipophilic, with accumulation in skin, nails, and adipose tissue. It is orally absorbed well but has only 40% bioavailability as it is metabolized during first-pass. It achieves peak blood concentration within approximately 2 hours.
• Terbinafine has strong binding with plasma proteins, primarily serum albumin.The tablet is excreted primarily via urine, with the rest coming out in faeces. Although its half-life of action is around 36 hours, it will stay in the skin and fat tissue for much longer periods.
