Tolnaftate vs Clotrimazole For Athlete’s Foot, Ringworm, Jock Itch – Uses & Side Effects

Tolnaftate vs Clotrimazole For Athlete’s Foot, Ringworm, Jock Itch - Uses & Side Effects

Tinea is the name of a group of diseases caused by a fungus. Types of tinea include:

  • Tinea versicolor – it is a mild infection that can occur on many parts of the body;
  • Tinea cruris (jock itch)- it  tends to create a rash in the moist, warm areas of the groin;
  • Tinea pedis (athlete’s foot) – it is an infection that occurs on the feet, especially between the toes;
  • Tinea corporis (ringworm) – it is a fungal infection of the top layer of your skin, which can form on your torso, arms, and legs;
  • Tinea capitis – it is a skin infection of the scalp. It mostly affects children.

Dermatophytes, more exactly – Epidermophyton, Trichophyton, and Microsporum species are responsible for most superficial human fungal infections.

Here is a comparison of two antifungal medicines that are used to treat these skin infections:

Tolnaftate

It is a man-made over-the-counter antifungal agent that belongs to the family of drugs called antifungals.

This antifungal can be found under the following brand names:

  • Tinaspore;
  • Tinaderm;
  • Tinactin;
  • Mycocide NS;
  • Lamisil Defense;
  • Clarus Antifungal;

Clotrimazole

It is an alkaline anti-fungal medication that can be either taken by mouth or applied as an ointment to the skin. It was originally discovered in 1969.

Mechanism of Action

Tolnaftate works by prohibiting the growth of a fungus which becomes less powerful and, eventually, the patient will be fully healed.

Clotrimazole works by killing sensitive fungi by interfering with the formation of the fungal cell membrane.

Uses

Tolnaftate topical is used to treat infections like:

  • ringworm (tinea corporis);
  • jock itch (tinea cruris);
  • athlete’s foot (tinea pedis).

Clotrimazole is prescribed for the treatment of pityriasis versicolor (cutaneous fungal infection), tinea cruris, tinea pedis, and tinea corporis.
