Pharmacodynamics and pharmacokinetics
The active component of the drug is fluoroquinolone , an antibiotic that inhibits the activity of DNA gyrase and topoisomerase 4 . Thus, replication and recombination of bacterial DNA, their renewal and reproduction become impossible.
Due to the mutation of gram-negative bacteria, they may become resistant to this type of antibiotic. The likelihood of cross-resistance with beta-lactams , aminoglycosides and macrolides is extremely low.
Moxifloxacin is active against:
- gram-positive bacteria ( Staphylococcus aureus, Streptococcus pyogenes group A, Streptococcus pneumoniae );
- gram-negative ( Haemophilus influenzae, Escherichia coli, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Enterobacter cloacae );
- other atypical types of bacteria ( Chlamydia spp., Mycoplasma pneumoniae, Mycoplasma spp., Chlamydia pneumoniae ).
In laboratory studies, moxifloxacin showed activity against Streptococcus milleri, Staphylococcus saprophyticus, Streptococcus mitior, Staphylococcus epidermidis, Staphylococcus hominis, Providencia rettgeri, Enterobacter aerogenes, Enterobacter sakazaki, Enterobacter intermedius, Morganella morganii, Str. agalactiae, Streptococcus dysgalactiae, Staphylococcus saprophyticus, St. haemolyticus, Enterobacter agglomerans, Proteus mirabilis, Proteus vulgaris, Providencia stuartii .
This group also includes anaerobes : Propionibacterium spp., Bacteroides distasonis, Porphyromonas magnus, Bacteroides ovatus, Bacteroides thetaiotaornicron, Clostridium perfringens, Prevotella spp., Bacteroides fragilis, Bacteroides eggerthii, Bacteroides uniformis, Porphyromonas anaerobius, Porphy romonas asaccharolyticus .
Also in vivo, the antibiotic inhibits the vital activity of gram-negative microorganisms: Enterobacter agglomerans, Klebsiella oxytoca, Bordetella pertussis, Enterobacter Intermedius, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Enterobacter aerogenes, Proteus mirabilis, Enterobacter sakazaki, Morganella morgana, Porphyromonas spp., Fusobacterium spp .
In the treatment of diseases caused by the above pathogens, the effectiveness of the drug has not been proven. This group also includes Caxiella burnettii and Legionella pneumophila .
Moxifloxacin eye drops do not exhibit phototoxic or photogenotoxic properties, unlike other quinolone .
When used topically, the drug is absorbed into the systemic circulation to a small extent, 1000 times less than when taken orally. The half-life from blood plasma is 13 hours.
Instructions for use VIGAMOX® (VIGAMOX)
Patients receiving systemic quinolone drugs have experienced severe, sometimes fatal, hypersensitivity reactions (anaphylaxis), sometimes immediately after the first dose. Some reactions were accompanied by acute vascular insufficiency, loss of consciousness, angioedema (including swelling of the larynx, pharynx or face), airway obstruction, shortness of breath, urticaria and pruritus.
If an allergic reaction to Vigamox® occurs, you must stop using the drug. If an acute hypersensitivity reaction to moxifloxacin or other components occurs, resuscitation measures may be required. If clinically indicated, oxygen is used to restore airway patency.
As with other antibiotics, long-term use can lead to excessive growth of non-susceptible microorganisms, incl. mushrooms If superinfection occurs, the drug should be discontinued and alternative therapy should be prescribed.
With systemic use of fluoroquinolones, including moxifloxacin, inflammation and tendon rupture may develop, especially in elderly patients and patients receiving concurrent corticosteroids. Plasma concentrations of moxifloxacin after ophthalmic use of Vigamox® are much lower than after oral use of moxifloxacin in therapeutic doses, but caution must be exercised and treatment with Vigamox® should be discontinued at the first sign of tendon inflammation.
Patients should be warned not to wear contact lenses if they have signs and symptoms of a bacterial eye infection.
Use in pediatrics
There is limited data on the effectiveness and safety of Vigamox® in the treatment of conjunctivitis in newborns. Therefore, the drug is not recommended for the treatment of conjunctivitis in newborns.
Vigamox® eye drops should not be prescribed for the prophylaxis or as empirical treatment of gonoblennorrhea in newborns, due to the possibility of development of fluoroquinolone resistance in Neisseria gonorrhoeae. Patients with eye infection caused by Neisseria gonorrhoeae should receive appropriate systemic treatment.
It is not recommended to use the drug in the treatment of Chlamydia trachomatis in patients under 2 years of age, because the use of the drug in this case has not been studied. For patients over 2 years of age with eye infections caused by Chlamydia trachomatis, appropriate systemic treatment is prescribed.
For neonatal conjunctivitis, treatment appropriate to the condition is prescribed, that is, systemic treatment of diseases caused by Chlamydia trachomatis and Neisseria gonorrhoeae.
Impact on the ability to drive vehicles and machinery
Vigamox® does not affect or has an insignificant effect on the ability to drive a car and use machinery. As with any other eye drops, temporary blurred vision or other visual disturbances may affect your ability to drive or operate machinery. If visual impairment occurs after instillation, the patient must wait until vision is restored before driving or operating machinery.
Side effects
Adverse reactions that occur when using the product are divided into local and systemic.
Local effects, in order of frequency of occurrence:
- pain and irritation on the mucous membrane of the eye;
- hyperemia of the eye or conjunctiva, dryness;
- swelling, punctate keratitis , blurred vision, erythema of the eyelid , local hemorrhages ( subconjunctival );
- erosion , opacification and defects of the cornea ;
- the appearance of deposits on the cornea, uncharacteristic discharge from the eye, endophthalmitis , sensitivity to light, blepharitis , increased pressure (intraocular).
Systemic adverse reactions:
- taste disorder, metallic or sour taste in the mouth, burning sensation;
- paresthesia , headaches , discomfort in the nasal cavity, lump in the throat, nausea and vomiting, low hemoglobin ;
- rapid heartbeat, shortness of breath, rash and itching on the skin , allergic reactions .

Vigamox, 1 piece, 5 ml, 0.5%, eye drops
For ophthalmic use only. Not for injection. It is not allowed to administer the drug subconjunctivally or directly into the anterior chamber of the eye.
There have been reports of serious and in some cases fatal (anaphylactic) hypersensitivity reactions in patients systematically taking quinolones; In some patients, the development of a reaction was observed after the first dose. Some reactions have been accompanied by cardiovascular collapse, loss of consciousness, angioedema (including swelling of the larynx, pharynx or face), airway obstruction, dyspnea, urticaria and pruritus.
If an allergic reaction to Vigamox® develops, you should stop using the drug. Severe acute hypersensitivity reactions to moxifloxacin may require first aid. Devices to restore oxygen supply and restore airway patency are used only for clinical indications.
Long-term use of the drug can lead to excessive growth of non-susceptible microorganisms, incl. mushrooms In case of superinfection, it is necessary to stop using the drug and prescribe adequate therapy.
Systemic use of fluoroquinolones, including moxifloxacin, may lead to tendon inflammation and rupture, especially in elderly patients and those taking concomitant corticosteroids. Thus, when the first symptoms of tendon inflammation appear, you should stop taking the drug.
Data on the effectiveness and safety of Vigamox® for the treatment of conjunctivitis in newborns are limited. Therefore, the use of the drug for the treatment of conjunctivitis in newborns is not recommended.
Vigamox® is not recommended for the prevention or empirical treatment of conjunctivitis, incl. gonococcal ophthalmia of the newborn, due to fluoroquinolone resistance of gonococci ( Neisseria gonorrhoeae
).
Patients with eye infections caused by gonococci ( Neisseria gonorrhoeae
) should receive appropriate systemic treatment.
Vigamox® is not recommended for the treatment of eye infections caused by Chlamydia trachomatis
, in patients under 2 years of age, because
No relevant studies have been conducted. Patients over 2 years of age with eye infections caused by Chlamydia trachomatis
should receive appropriate systemic treatment.
Newborns with ophthalmia neonatorum should receive appropriate treatment based on their condition, such as systemic treatment in cases caused by gonococci ( Neisseria gonorrhoeae
) or
Chlamydia trachomatis
.
Patients are not recommended to wear contact lenses if they have signs of infectious diseases of the anterior segment of the eye.
Do not touch the tip of the dropper bottle to any surface to avoid contamination of the bottle and its contents.
The bottle must be closed after each use.
Use in children.
Vigamox® can be used in pediatrics in children from 1 year of age in doses similar to adults.
Influence on the ability to drive vehicles and operate machinery.
After using the drug, a temporary decrease in the clarity of visual perception is possible and until it is restored, it is not recommended to drive a car or engage in activities that require increased attention and reaction.
Vigamox eye drops, instructions (method and dosage)
ophthalmic only .
According to the instructions for use of Vigamox, one drop is prescribed into the affected eye, up to 3 times a day. As a rule, the patient’s condition improves after 5 days of taking the drug, but treatment should be continued for another 2-3 days.
If there is no improvement within 5 days of taking the drug, you should consult a specialist. For children older than one year, in patients with renal failure and liver disease, no dosage adjustment is required.
