Action: How Lamisil Tablets Works
Terbinafine, the active ingredient in Lamisil tablets, works by killing the dermatophytes.
Terbinafine interferes specifically with fungal sterol biosynthesis at an early step. This leads to a deficiency in ergosterol and to an intracellular accumulation of squalene, resulting in fungal cell death. Terbinafine acts by inhibition of squalene epoxidase in the fungal cell membrane. The enzyme squalene epoxidase is not linked to the cytochrome P450 system. When given orally, the drug concentrates in skin and nails at levels associated with antifungal activity.
Lamisil tablets contain 250 mg terbinafine per tablet.
Lamisil tablets also contain magnesium stearate , silica-colloidal anhydrous, hypromellose , sodium starch glycollate, and cellulose-microcrystalline .
Lamisil tablets do not contain lactose, sucrose, gluten, tartrazine, or any other azo dyes.

Choice Of Base Formulation
A medication’s potency often is changed with its base. For example, some will be classified one or two strengths higher when moving from cream to ointment. As a rule of thumb, an ointment base is more occlusive and will drive the medication into the skin more rapidly than a solution or cream base.
The manufacturer of each topical product has total control over the content of the base of a medication. Although containing the same active ingredients, one manufacturer’s cream might be more acidic than the next, which could cause skin irritation or change its absorption rate. For example, a vaginal formulation of antifungal cream might irritate the skin less than an athlete foot formulation of miconazole cream. These variations can, on occasion, result in different , even though the active ingredient is the same. No comparative potency labeling exists to ensure equal efficacy between brands of topical steroids . Studies have confirmed that the potency of some topical steroid products may differ according to manufacturer or brand. An example of this is the case of brand name cream and cream in clinical studies have demonstrated significantly better vasoconstrictions than some forms of this drug produced by manufacturers. However, in a simple base like an ointment, much less variation between manufacturers is common.
