Antifungals are molecules that allow us to fight against fungi, also called mycosis. Microscopic, mycoses infect the skin, mucus membrane, hair, and nails... Most fungi favor maceration zones where they like to develop, as these areas are warm and humid and favorable to their development (between the toes, the folds of skin in obese people, the digestive tract...). Certain antifungals are local in the form of creams, ointments, shampoo, or powders, when the affected surface is accessible, like the mouth in the case of thrush, the skin, or the hair in the case of ringworm. However, they can also be administered orally, notably in the treatment of fungi in the digestive tract.
