Drops "Oftan" - an ophthalmic remedy that has become widespread. The drug has a fast and effective action. There is a whole series of "Oftan" - "Katahrom", "Dexamethasone", "Timolol", "I'm going." The drugs are designed to correct diseases of the visual system, but they all have a different mechanism of action.
Oftan Katahrom eye drops: description and composition
An ophthalmic drug is a metabolic drug. It has a regenerating effect on the tissues of the visual organ. The instructions for eye drops "Oftan Katahrom" are indicated as a combined remedy that improves energy metabolism in the lens. The drug has an antioxidant effect, improves the nutrition of the tissues of the visual organ. The action of the drug is due to three active substances:
- Adenosine (2 mg) is a nucleoside present in all tissue cells. It has a vasodilatory effect. When expandingblood vessels improves blood circulation, enrichment of tissues with oxygen is ensured. Adenosine speeds up metabolic processes in the lens.
- Nicotinamide (20 mg) is a vitamin derived from nicotinic acid. Improves redox reactions, ensures the normal course of various metabolic processes. Relieves fatigue, redness of the eyes.
- Cytochrome C (0.675 mg) is an enzyme derived from the tissues of the hearts of cows, buffaloes and other cattle. The substance improves tissue respiration, accelerates oxidative reactions, accelerates metabolic processes, and provides oxygen utilization.
Medicinal action of "Oftan Katahrom"
The main pharmacological action is to ensure normal metabolic processes in the eye. Substances, freely penetrating the cornea, prevent the accumulation of high molecular weight alcohols (polyols) by deactivating enzymes. Excess fluid is quickly removed from the intercellular space, preventing the violation of the integrity of the membranes and clouding of the lens.
Components prevent the formation of peroxide radicals of photochemical, autooxidative origin. The instructions for Oftan eye drops indicate that the product improves the diffusion and transport of nutrients and oxygen through the capsule to the biological lens of the visual organ.
The lens is 40% high molecular weight proteins. With age, there is a modification of enzymes, the transparency of the light-refractive apparatus of the eye deteriorates. Drops prevent denaturation of proteins, returning their native structure.
Indicationsand instructions for use
In ophthalmic practice, the drug is used for minor visual impairment caused by clouding of the lens. It is prescribed for older people with the following symptoms:
- increased light sensitivity;
- frequent appearance before the eyes of glare, spots, "flies";
- rapid fatigue of the visual organs;
- distorted color perception;
- pupil becomes yellowish or greyish.
Instruction drops Oftan Katahrom:
- rinse eyes and hands well with water before use;
- conjunctivally instill 1-2 drops two to four times a day;
- after depositing the funds, it is necessary to blink to accelerate the spread of the substance;
- excess can be removed with a cotton pad;
- duration of use to be determined by physician.
Contraindications and side effects
According to the instructions drops "Oftan Katahrom" is contraindicated in patients with hypersensitivity to any of the components of the substance. The drug is not prescribed to children and adolescents under the age of eighteen.
Clinical studies on the use of an ophthalmic agent in women during gestation have not been conducted in the same way as during breastfeeding. Treatment of pregnant and lactating mothers with the drug "Oftan Katahrom" should be carried out according to the prescription and control of the doctor. Before therapy, the doctor assesses the possible danger to the child.
Sidelinethe action is often local:
- In the first minutes after instillation, a slight pain, burning sensation may be felt. This is a mucosal reaction to a foreign substance that passes quickly.
- In case of intolerance to the components or if the dosage is regularly exceeded, allergic conjunctivitis may develop. It is manifested by hyperemia of the eyeball, tearing.
- Contact dermatitis is rare. It is characterized by redness of the eyelids and the area around the eyes. Red small bubbles form on the face.
- In rare cases, there may be dizziness, short-term nausea, low blood pressure, loss of strength.
- The vasodilating effect of nicotinic acid can cause a pulsation in the temples, a feeling that the temperature has risen. If symptoms persist within two days, discontinue use and consult a doctor.
Special Instructions
Before using Oftan Katahrom eye drops, patients who wear contact lenses should remove the optics and put them on 15 minutes after the procedure. This is due to the fact that the components can be deposited in the lenses and have a negative (irritating) effect on the tissues of the visual organ.
When using other ophthalmic products, it is necessary to take a break between procedures, approximately 15 minutes.
The use of drops does not affect driving. But it is better to get behind the wheel not earlier than 20 minutes after instillation.
The drug is stored in the refrigerator: 3 years in package and a month after opening.
Using Oftan Pilocarpine eye drops
Ophthalmic remedy has m-cholinomimetic action. Drugs with this effect are used to treat a wide variety of diseases. In the treatment of pathologies of the visual system, the medicinal effect is due to an improvement in the outflow of aqueous humor from the eye chambers and a decrease in intraocular pressure.
The active pharmaceutical substance of the drug is pilocarpine hydrochloride. The substance is an alkaloid of the evergreen tree Pilocarpus. Stimulates contraction of the smooth muscles of the iris. Promotes the opening of the venous circular vessel and fountain spaces in the corner of the anterior chamber of the visual organ, increases the tone of the ciliary muscle.
Based on the instructions for use, Oftan Pilocarpine eye drops are prescribed for the following vision pathologies:
- occlusion (blockade) of the central retinal artery;
- increased intraocular pressure of a constant or intermittent nature;
- getting into the vitreous body of blood due to rupture of blood vessels (hemophthalmos);
- destruction of optic nerve fibers with their replacement by connective tissue.
Oftan Dexamethasone
Glucocorticoid group drug with anti-inflammatory, anti-allergic action.
The active substance of the drug dexamethasone sodium phosphate. Reduces capillary permeability, stabilizes three-layer lipoprotein membranes of cells. Reduces the outflow of lymphoid fluid, inhibits the migration of monocytes to the focusinflammation, reducing the body's response to pathogenic stimuli.
The anti-allergic effect is due to inhibition of the synthesis of allergy mediators, the production of immunoglobulins.
Dexamethasone accelerates protein catabolism. Restores electrolyte balance by reducing calcium absorption, sodium and water retention.
Indications for the use of drops "Oftan Dexamethasone" are the following diseases:
- nonpurulent forms of conjunctivitis;
- keratitis without purulent exudate;
- inflammation of the edges of the eyelids (blepharitis);
- non-purulent inflammation of the outer connective tissue membrane of the eyeball (scleritis);
- inflammation of the vascular retina of the eyes of various genesis;
- chemical, physical superficial injury to the cornea;
- choroiditis.
Oftan Timolol
Ophthalmic agent of the beta-blocker group. It has a hypotensive, antiglaucoma effect.
The active substance of the drug timolol. When applied topically, it reduces the production of aqueous humor and enhances its outflow, thereby reducing eye pressure, both elevated and normal. The agent begins to act in 20 minutes. The maximum effect is achieved after two hours and persists for a day. The drug does not cause pupil dilation or constriction and does not affect the ability of the eye to clearly distinguish the image.
The use of Oftan Timolol drops is indicated for certain pathologies of the visual system, which include:
- simplechronic, more often bilateral (not necessarily symmetrical) glaucoma;
- a pathology characterized by the accumulation of fluid inside the eyes due to the iris closing the anterior angle of the chamber of the visual organ (closed glaucoma);
- secondary glaucoma that develops after damage to the integrity of the visual organ due to mechanical or chemical damage;
- glaucoma of inflammatory genesis;
- congenital increased intraocular pressure.
Ophthalmic preparation "Oftan Idu"
Antiviral eye drops. The active pharmaceutical substance of the drug idoxuridine. Its pharmacological action is due to a violation of the synthesis of nucleic acids and the suppression of the process of division of viral cells, mainly herpes.
Ophthalmic drops are prescribed in the following cases:
- therapy (alone or in combination with other drugs) and prevention of corneal inflammation caused by herpes simplex virus;
- tree-like corneal ulcer;
- herpetic conjunctivitis.
The duration of therapy with Oftan Idu eye drops is determined by the ophthalmologist, but it should not exceed three weeks.
Analogues
If necessary, it will not be difficult to replace the eye drops of this series. Analogues can be selected both structurally and only according to the mechanism of action. Regardless of the complexity of the disease, the drug shouldbe selected by a specialist.
Analogues of eye drops "Oftan":
- "Taufon" - a drug of metabolic action. It is used for corneal dystrophy, various types of cataracts (including senile), as a stimulator of regeneration processes in corneal injuries.
- "Rotima" - generic "Oftan Timolol", prescribed for all types of glaucoma.
- Maxidex is a glucocorticosteroid available in drops and as an ointment. Indications: blepharitis, keratoconjunctivitis, iridocyclitis, conjunctivitis. Thermal and chemical burns of the cornea.
- "Lacrisin" - eye drops of keratoprotective action. They are prescribed for corneal erosion, keratopathy, eversion and other eyelid deformities, lagophthalmos, dry eye syndrome, keratosis.
Ophthalmic product reviews
Drugs of the "Oftan" series are rarely bought for self-therapy, they are prescribed by a doctor. Pathologies of vision, if no action is taken, develop rapidly. The ophthalmologist prescribes drops at the slightest pathological changes. In the reviews, people write that they did not feel any effect - "as they saw it normally, they see it." This indicates that the drug is effective.
Negative reviews are associated with the high price of the drug, especially considering that one bottle is not enough for the course.
