Miramistin: instructions for use

Miramistin is an antiseptic that has been developed in our country and is able to fight against various microorganisms, including bacteria, fungi, and protozoa. Also, the drug is able to stimulate the immune system. Miramistin is included in the drug registries of most countries and is sold in pharmacies without a prescription.

Principle of Operation

The active substance is benzyldimethyl [3- (myristoylamino) propyl] ammonium chloride, belonging to the category of surface-active substances (surfactants). The compound was developed in the late 1970s in the Soviet Union. It was supposed to be used for disinfecting spacecraft during long flights. However, in the early 1990s, the drug became available to the consumers in Russia and other countries.

Miramistin has three main types of action:

  • Antiseptic
  • Immunostimulating
  • Accelerate wound healing

The mechanism of the antiseptic effect of a substance is based on the fact that it affects the lipid walls of microorganism cells. In this case, the permeability of the walls is broken and the microbes die. The drug is not toxic to the cells of the human body.

Immunostimulating action is associated with the ability of the drug to increase the activity of phagocytes and macrophages.

The positive effect on wound healing is due to the fact that Miramistin can serve as an absorbent to remove pus and fluid that occurs during inflammation of wounds. This tool does not irritate healthy tissue and does not interfere with the growth of new tissues.

There is reason to believe that it is active against various viruses – the herpes virus and HIV. This is indicated by some studies.

One of the beneficial qualities of Miramistin is that, when used externally, it does not penetrate the skin. This means that it does not enter the circulatory system and does not accumulate in the body.

The same can be said about the use of Miramistin for treating children. To date, there is no sufficient evidence base on the safety of the drug for children. Therefore, the manufacturer does not recommend using it for the treatment of children under 3 years. If such a need arises, then in this case it is best to consult a pediatrician.

It is clear that an adult will not intentionally swallow the medicine, but when using it as a child, a similar situation may occur.
