Pharmacological properties of the drug Miramistin
Pharmacodynamics. The action of miramistin is based on the direct hydrophobic interaction of the molecule with the lipids of the membranes of microorganisms, leading to their fragmentation and destruction. In this case, part of the miramistin molecule, plunging into the hydrophobic portion of the membrane, destroys the supra-membrane layer, loosens the membrane, increases its permeability to high-molecular substances, changes the enzymatic activity of the microbial cell, inhibiting enzyme systems, which leads to inhibition of the vital activity of microorganisms and their cytolysis. Unlike other antiseptics, Miramistin has a highly selective action against microorganisms, since it has virtually no effect on human cell membranes. This effect is associated with a different structure of human cell membranes (much longer lipid radicals, which sharply limit the possibility of hydrophobic interaction of miramistin with cells). Miramistin has a pronounced antimicrobial effect against gram-positive and gram-negative, aerobic and anaerobic, spore-forming and asporogenic bacteria in the form of monocultures and microbial associations, including hospital strains with multidrug resistance to antibiotics. It has a detrimental effect on pathogens of sexually transmitted diseases: gonococci, Treponema pallidum, Trichomonas, chlamydia, selectively on herpes viruses. Has an antifungal effect on ascomycetes of the genus Aspergillus and genus Penicillium , yeast ( Rhodotorula rubra, Torulopsis gabrata , etc.) and yeast-like ( Candida albicans, Candida tropicalis, Candida krusei , etc.) fungi, dermatophytes ( Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton verrucosum, Trichophyton schoenleini, Trichophyton violaceum, Epidermophyton Kaufman-Wolf, Epidermophyton floccosum, Microsporum gypseum, Microsporum canis, etc.), as well as other pathogenic fungi (for example Pityrosporum orbiculare ( Malassezia furfur )) in the form of monocultures and microbial associations, including fungal microflora with resistance to chemotherapy drugs. Under the influence of miramistin, the resistance of microorganisms to antibiotics decreases. Miramistin has an anti-inflammatory and immunoadjuvant effect, enhances local protective reactions, regenerative processes, activates nonspecific defense mechanisms due to modulation of the cellular and local humoral immune response. Pharmacokinetics. When applied topically, it is not absorbed through the skin and mucous membranes.
Composition and release forms of the drug

Why do you need to rinse your mouth after tooth extraction?
After the tooth extraction procedure, a hole with damaged blood vessels remains. A blood clot forms in it, protecting the wound from infection. New mucous membrane grows under it, and the periosteum heals. If the clot is accidentally removed or washed out, bleeding may resume. The wound will become vulnerable to various infections. For this reason, complications often develop. Therefore, oral care after tooth extraction should be extremely careful.
Rinsing is prescribed to prevent wound infection and the occurrence of purulent-septic complications. They promote rapid healing of the gums and reduce swelling that is possible after surgery. Only a doctor can tell you whether it is necessary and possible to rinse your mouth after tooth extraction. Trying to treat a wound on your own can be harmful.

After treating the urethra, vagina, inner thighs, pubis and genitals with miramistin, it is not recommended to urinate for 2 hours. Use during pregnancy and lactation. Since drug resorption is almost completely absent, Miramistin can be used during pregnancy and lactation. The ability to influence the reaction rate when driving a vehicle or working with other mechanisms. During treatment with the drug, it is possible to drive vehicles and engage in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
How to rinse your mouth with Miramistin after tooth extraction
In the first 1–2 days after extirpation, any rinsing is prohibited. Otherwise, you can wash the clot out of the well. If an infection gets into it, alveolitis or osteomyelitis will begin. In the first case, the socket becomes inflamed, in the second – the bone. That's why they only do baths. Take one sip (10–15 ml) of liquid at room temperature into your mouth, hold it for 1–2 minutes and spit it out.
Next, you should adhere to the following rules:
- Starting from the 3rd–4th day, you can carry out gentle rinsing. To do this, you need to tilt your head several times from the side of the extracted tooth to the healthy one.
- Baths and rinses are carried out immediately after meals.
- After treating the oral cavity with Miramistin for 1–1.5 hours (optimally up to two), you should refrain from smoking, drinking and eating.
In most cases, patients are prescribed 3-4 rinses per day. The course of treatment is up to a week.
After tooth extraction, patients should also pay special attention to oral care. If you are concerned about whether it is possible to do ordinary hygienic rinses, then you should also avoid them at first. In order to maintain hygiene, patients are recommended to use the same baths. To do this, take warm water into your mouth, hold it a little and spit it out. And so several times until you feel fresh.

Miramistin is really good, but it’s just expensive, almost 400 rubles for 150 milliliters. What is the best way to replace it?

- Dear Dilyara, in terms of the principle of action and set of positive properties, budget drugs such as Chlorhexidine and Furacilin are similar to Miramistin. But before using them, do not forget to consult your doctor, because they have a number of contraindications.

Stomatitis
The drug is a broad-spectrum antiseptic, fights all types of bacteria, copes with the herpes virus and Candida fungus, which is why it is so often prescribed in the complex treatment of stomatitis, especially herpetic and candidiasis. However, if you suspect stomatitis, you should not prescribe this medicine to yourself or your child, because it is not always effective. So, with an allergic type of pathology, the remedy will not work, and it is almost impossible to determine without the help of a doctor what type of disease you have developed.

A few words about the history of the creation of the drug
"Miramistin" as a drug first began to be developed in the distant 70s. At first, it was promoted as a composition that was supposed to be used at interorbital stations to disinfect the skin of astronauts and to treat objects, things, and workplaces around them. However, after the collapse of the USSR, research on the active antiseptic substance miramistin was suspended; they were returned to them again in the late nineties. It was then that the medicine first began to be put on sale, but to solve narrow-profile problems (for example, the prevention of sexually transmitted diseases). There was no talk of him as a child at all.
Miramistin allows you to solve problems in many areas of medicine
Later, additional studies were carried out, which allowed specialists to expand the list of areas of application of the drug. And its safety, almost one hundred percent effectiveness and the absence of contraindications, except for individual intolerance, made it possible to use Miramistin for children.
Today the drug is produced by a production facility located in the Moscow region. The medicine is in demand in Russia, Ukraine, Belarus, Kazakhstan, Turkmenistan, and Armenia. They also plan to sell the product in China soon1.
Now let’s look at the cases in which doctors at dental clinics recommend using the drug. You need to understand that Miramistin is equally often prescribed in both pediatric and adult dentistry as an additional measure to the main treatment. It is not a panacea, but the instructions for its use state that, in combination with other measures, it helps get rid of various problems.
Why is Miramistin prescribed in gynecology?
In gynecology, the drug can be used for:
- Impregnation of vaginal tampons. This method of administering an antiseptic shows good results in the treatment of cervical erosion, metritis, and endometritis.
- Douching. The method is widely used for the treatment and prevention of sexually transmitted diseases.
- Introduction into the genitourinary canal using a catheter is a method of treating urethritis and cystitis. The manipulation can only be performed by a person with medical education.
- Electrophoresis sessions. Physiotherapeutic procedures using Miramistin help cure pelvic pathologies such as salpingitis, oophoritis, etc.
The method of treatment and duration of therapy are selected by the attending physician in each specific case.
