Pharmacodynamics and pharmacokinetics
This substance inhibits the activity of enzymes that take part in the processes of sterol in fungal cells. Amorolfine inhibits the enzymes delta-14-reductase and delta-7–8 isomerase , significantly reduces the concentration of ergosterol , which leads to the accumulation of abnormal stereoisomers of sterols in cells. Under the influence of the drug, the structure of the fungal cell membrane is disrupted. Depending on the dosage used, the product may have a fungicidal or fungistatic effect.
The substance exhibits activity against fungi of the genus Candida, Cryptococcus and Malassezia; to dermatophytes Microsporum, Trichophyton and Epidermophyton; molds Scopulariopsis, Alternaria and Hendersonula; dimorphic fungi Histoplasma, Coccidioides and Sporothrix; actinomycetes, Dematiaceae fungi.
Most often, the medicine is used in the form of nail polish. After application to the surface of the nail, the product easily and deeply penetrates the nail plate and nail bed. Has a low degree of systemic absorption.

Directions for use and doses
Externally. Apply to affected fingernails or toenails 1-2 times a week as follows:
- Before using Amorolfine varnish, it is necessary to remove as much of the affected nail as possible with scissors, and carefully treat the affected areas of the nail on its surface using the supplied nail file.
- Then clean the surface of the nail and degrease it with the supplied swab moistened with alcohol. Treatment of nails with a file and a swab with alcohol must be carried out before each use of the drug.
- Dip a spatula into the varnish. The spatula should be removed from the bottle without touching its neck; you should not wipe off excess varnish on the neck of the bottle.
- Apply the varnish to the entire surface of the affected nail using a spatula. Repeat the above procedure for each affected nail.
- Close the bottle of varnish tightly immediately after use to prevent it from drying out.
- After use, wipe the spatula with a swab. Throw away the used tampon.
- Allow the varnish to dry for approximately 3-5 minutes.
The above procedure should be carried out for each affected nail.
Before each subsequent application of Amorolfine, it is necessary to remove the previous layer of varnish with a swab, file the nails, and then clean and degrease the surface using a swab.
Treatment should be carried out continuously until the affected area is completely healed and the nail plate is regenerated.
If you forgot to apply varnish on the scheduled day, then it must be applied as soon as possible.
The duration of treatment is usually 6 months for fingernails and 9 to 12 months for toenails.
If there is no improvement within 3 months, it is recommended to consult a doctor.
Due to the slow growth of nail plates, the first signs of improvement may become noticeable only after 2-3 months of using the drug. If there are no signs of improvement after 3 months, or if symptoms worsen or new symptoms appear, you should consult your doctor. Use the drug only according to the indications, the method of use and in the doses indicated in the instructions for use.

Reviews
Reviews of Amorolfine nail polish:
- “... After visiting the hospital, I noticed that I had fungus on my nails, they started treating me with ointments, but they seemed ineffective to me. But this varnish helped a lot, I applied it once every 7 days, a year has already passed, and there is no trace of fungus on my nails”;
- “... I’ve been treating fungus with this remedy for several months now, if you follow the recommendations in the instructions, the drug is quite effective. I use the polish once every 3 days. I’m happy with everything so far”;
- “... This remedy did not help me; the fungus grew as it wanted with or without it. Two nails were affected and had to be treated with folk remedies”;
- “... The varnish seems to help if you apply it regularly, but the price doesn’t suit me. I wish I could find something cheaper.”
Mistakes in treating toenail fungus
Nail fungus or onychomycosis is an unpleasant disease that may not be noticed immediately. The fungus destroys your nail plate, causing discomfort and pain; if treatment for onychomycosis is started, this can lead to soft tissue pathologies. The fungus can easily spread to healthy fingernails or toenails, and this poses a great danger to your health and the health of others.
If you have any doubts about the health of your nails, the best thing to do is make an appointment with a dermatologist. Only with complex treatment, consisting of a course of medication, regular foot hygiene and special treatment of the nail plates, will the treatment bring a positive result.
Main symptoms of fungal infections:
● Brittle, rough nails
● Deformation of the nail plate
● Presence of inflamed tissue around the nail
● Delamination, thickening or thinning of the nail plate
● Presence of brown, black or yellow areas on the nails.
How do you get nail fungus?
Ways of infection with onychomycosis. If you follow the rules of hygiene, have good immunity, and have healthy and well-groomed skin, the risk of contracting a fungal infection is not high. The fungus often enters the body through abrasions, cuts, cracks, and altered injured areas of the nails and skin. Excessive sweating or dry skin, or wearing tight shoes can contribute to the growth of the fungus.
You are more vulnerable to nail fungus if:
● You have varicose veins
● Reduced immunity
● You wear rubber shoes that don't breathe
● There are endocrine and vascular diseases
● Have been in contact with a person infected with a fungus
● There is flat feet.
What danger does toenail fungus pose to humans?
At an advanced stage of onycochomycosis, nail fungus causes an allergic reaction, has an intoxicating effect on the body, and can affect internal organs.
How to cure nail fungus?
When treating nail fungus, local medications can be used - creams, ointments, patches, which can also be used at home. Various spray options are available that have strong antifungal, anti-inflammatory and antiseptic properties.
At the early stage of the disease, the use of sprays or creams is recommended. Do not forget that treating nail fungus is not only about getting rid of external manifestations. During treatment, the dermatologist prescribes systemic medications. The drug can be prescribed in the form of tablets, which will be taken for a course of three to six months.
The most common mistakes when treating toenail fungus.
The moisture of your feet. Fungus in the form of spores is everywhere around us. When the skin humidity is more than 80%, fungal spores begin to multiply and infect the nail plate and surrounding skin.
The presence of fungal spores on things. When ironing socks with steam, you kill the active fungal spores remaining there. If this is not done, then from the spores, in the presence of damp skin of the feet (favorable environment), high humidity of the shoes, the fungus actively begins to multiply.
Shoe hygiene. When starting treatment for nail fungus, be sure to treat all the shoes you wear. Use a personal towel intended only for feet.
Remains of fungal spores on instruments. All tools for cutting nails must be treated with disinfecting solutions; it is recommended to use disposable files to care for affected nails. If the fungal spores remain on the tools, then you can manually remove them for years, cut out traces of the fungus along with your nail, but this will not bring any results.
What should you follow when treating toenail fungus?
If you do not follow the recommendations during treatment of nail fungus, a relapse may occur. Try to always keep your feet clean and change your socks daily. It is important for your feet to wear the right shoes to prevent your feet from getting sweaty. After taking any water procedures, wipe your feet dry, paying special attention to the area between the toes.
Use an individual foot towel, which must be dried after use. If your shoes become wet, dry them immediately. It is recommended to change indoor shoes at least twice a year during treatment. Foot baths with soda and salt will also be useful. Feet should be washed daily using laundry or tar soap.
Always follow the rules of hygiene when visiting public places: saunas, baths, hammam, swimming pools. Do not self-medicate; it would be best to contact a dermatologist who will prescribe a course of treatment for you so that you can quickly get rid of toenail fungus and save your time and nerves.
