Product Overview & Brand Variants

INN and Brand Names Used in Canada

The International Nonproprietary Name (INN) for Lamisil is terbinafine. In Canada, it is primarily marketed under the brand name Lamisil, available in various forms including tablets and creams. These brand variants are designed to cater to different patient needs based on the type of fungal infection being treated.

Legal Classification Under Health Canada

Lamisil is classified differently depending on its formulation. The oral tablet form requires a prescription (Rx) in Canada, while topical options like the cream and spray are classified as over-the-counter (OTC) products in some jurisdictions. This legal classification plays a crucial role in how patients access and utilise the medication, impacting both accessibility and affordability.

Indications in Local Canadian Medical Practice

Approved Uses (Health Canada DIN Context)

Health Canada has approved Lamisil for several common fungal infections, including tinea pedis (athlete's foot), tinea corporis (ringworm), and onychomycosis (nail fungus). These indications are backed by regulatory data and provide healthcare practitioners with confidence when prescribing Lamisil to patients.

Off-label Patterns in Canadian Healthcare

While Lamisil is primarily used for approved indications, some healthcare practitioners may prescribe it for off-label uses, such as treating eczema or other resistant fungal infections. This practice is typically guided by clinical observations and patient needs, which may warrant further monitoring and healthcare provider involvement.

How It Works in the Body

Layman’s Explanation

Terbinafine, the active ingredient in Lamisil, primarily works by inhibiting a critical enzyme involved in fungal cell wall synthesis, leading to the death of the fungus. This action makes it effective for treating various fungal infections, as it disrupts the structure necessary for fungi to survive and reproduce.

Clinical Detail from Health Canada Resources

From a clinical standpoint, terbinafine exhibits strong fungicidal activity against dermatophytes. It acts by blocking the conversion of squalene to ergosterol, a vital component of fungal cell membranes. The pharmacokinetics of the drug allows for effective concentrations in both systemic and local treatments, making Lamisil a worthwhile option.

Dosage & Administration

Standard Regimens Per Canadian Guidelines

According to Canadian guidelines, the dosage for Lamisil varies based on the condition being treated.

• For onychomycosis, the standard dosage is 250 mg orally once daily for 6-12 weeks.
• Tinea pedis or tinea cruris generally requires 250 mg daily for 2-6 weeks.
• Topical applications should be applied as a thin layer once or twice daily for 1-4 weeks.

Adjustments by Patient Type

Dosage adjustments may be necessary for certain populations, including: - Elderly individuals, who may need monitoring for potential drug interactions or appreciate dosage modifications. - Children, where recommendations can vary, and it's important to follow specialist guidelines. - Patients with renal or hepatic impairment must exercise caution when using oral forms to avoid adverse effects or toxicity.

Contraindications & Side Effects

Common (Health Canada-approved list)

Lamisil (terbinafine) is widely used to fight various fungal infections, but it’s important to be aware of the side effects and contraindications. Based on Health Canada's data, notable common side effects include:

• Gastrointestinal issues such as nausea, diarrhea, and abdominal pain
• Headaches and skin rashes
• Itching and taste disturbances
