Terbinafine, used to treat skin infections, is produced by several pharmaceutical companies and sold under different brand names. Notable among these brands are 'Lamisil' by Novartis and 'Terbinafine Actavis.' These brands have remained popular in the market because of their effectiveness in treating skin infections.

• Nail infections (Onychomycosis)
• Scalp ringworm (Tinea capitis)
• Skin candidiasis
• Yeast infections of the skin (Pityriasis versicolor).

The effectiveness of terbinafine cream relies on how it works with other treatments. As a type of antifungal called an allylamine, it disrupts the production of ergosterol, an element in the membrane of fungus cells, by blocking the enzyme squalene epoxidase. Doing this leads to an increase in squalene (a substance that helps create sterols) within the fungus cell, which ultimately causes cell death and decreases the number of fungus cells.

The time it takes for terbinafine cream to start working can differ from person to person. Depend on the severity of the fungal infection. Typically symptoms begin to improve during the week of treatment. However, completely getting rid of the infection may require treatment, sometimes lasting several weeks.

• Sorbitan Monostearate; an emulsifier that helps maintain the consistency of the cream.

All these inactive ingredients play roles in ensuring that the cream remains stable and user friendly and ultimately satisfies the patient's needs.
