The anti-infective drug is the substance applied locally, ingested, or injected in order to fight infections. Antibacterial, antiviral, antifungal, antiparasitic agents are included in the anti-infective category.

When the human being or any domestic animal has been attacked by a microbe or any other parasite, it is important to have substances that are active against the invading agent, without affecting the host (chemotherapeutic action). However, in this case there are three factors that must be taken into account and that influence each other: the microorganism or parasite, the anti-infective agent (antibiotic, antiviral, antifungal) and the host.

Anti-infective agents have specific medications to be used in dermatological therapy.

Clotrimazole (trade name Canesten or Clotrimin) is an antifungal medication commonly used to treat infections (of humans as well as other animals) such as vaginal yeast infections, oral candidiasis, and dermatophytosis.

Antivirals are a type of drug used to treat infections caused by viruses. Just like antibiotics (specific for bacteria), there are specific antivirals for different types of viruses.

Currently there are four antiviral drugs against influenza viruses: oseltamivir, zanamivir, amantadine and rimantadine. They can be administered: Orally in capsules, tablets or in solution (liquid or syrup) (Oseltamivir). Via inhaled (Zanamivir).

The antiviral Oseltamivir helps reduce the duration of flu symptoms such as blocked nose or runny nose, sore throat, cough, muscle or joint pain, tiredness, headache, fever and chills. This drug blocks the actions of type A and B influenza viruses in your body.

Oseltamivir is used to treat influenza in people 2 weeks of age and older who have had flu symptoms for 2 days or less.

Tamiflu is an antiviral medication that comes in the form of capsules (30 mg, 45 mg and 75 mg) and powder to form an oral suspension (6 mg / ml and 12 mg / ml). It contains the active substance oseltamivir.
