Pharmacological properties
Pharmacodynamics
Oxybuprocaine has a short-acting local anesthetic effect. The pharmacological actions of the drug include:
- reversible blockage of sensitive nerve endings;
- penetration through the membrane of nerve cells;
- violation of transmembrane transport of ions (especially sodium);
- decrease in the flow of impulses to the central nervous system.
The drug does not affect the pupil's ability to accommodate and its size.
In comparison with tetracaine and other local anesthetics, the irritating effect of Oxybuprocaine on the cornea and conjunctiva is less pronounced.
Pharmacokinetics
After a single instillation of drops into the conjunctival cavity, oxybuprocaine hydrochloride is easily absorbed into the corneal stroma through the mucous membranes. After 1-3 minutes, anesthesia occurs. Over the next 15 minutes, a quantitative decrease in the stromal concentration of the drug is noted, due to which, with a single instillation, an anesthesia period of 15 to 20 minutes is provided.
Indications for use
- tonometry;
- local anesthesia in ophthalmology, including superficial anesthesia of the conjunctiva and cornea;
- short-term operations on the conjunctiva and cornea;
- gonioscopy and other diagnostic examinations (before subconjunctival injections);
- extraction of sutures and foreign bodies from the conjunctiva and cornea.
Contraindications
Absolute:
- children under 2 years of age;
- individual intolerance to the components of the drug, including to other local anesthetics of the group of esters of para-aminobenzoic acid or amides.
Relative (Oxybuprocaine eye drops are used under medical supervision):
- pseudocholinesterase deficiency;
- malignant myasthenia gravis;
- epilepsy;
- selection of bacteriological smears (drops cannot be injected before the procedure, since they have bacteriostatic properties and prevent the development / reproduction of bacteria);
- pregnancy;
- period of breastfeeding.
Oxybuprocaine, instructions for use: method and dosage
Oxybuprocaine eye drops are applied topically by instillation into the conjunctival sac.
Recommended dosage regimen:
- corneal and conjunctival anesthesia (to remove foreign bodies): 1 drop 3 times for 5 minutes;
- removal of deeply located foreign bodies: 1 drop from 5 to 10 times, observing an interval of 30 to 60 seconds between instillations;
- subconjunctival injections: before the procedure, 1 drop 3 times for 5 minutes;
- gonioscopy, tonometry and other examinations: 1–2 drops each.
Anesthesia for up to 60 minutes is provided by three times instillation of the drug, observing an interval of 4 to 5 minutes.
Before using drops for the first time, turn the cap (lid) of the dropper bottle clockwise until the neck is punctured. Next, the cap (lid) must be removed and by squeezing the body of the bottle with your fingers, drip the solution into the conjunctival sac. After each use, it is important to close the bottle with the cap (cap) until it stops.
Side effects
Possible adverse reactions (> 10% - very often;> 1% and 0.1% and 0.01% and <0.1% - rarely; <0.01% - very rare; frequency not established - determine the frequency of occurrence of unwanted reactions according to the available data is impossible):
- allergic reactions: the frequency has not been established - anaphylactic shock;
- local reactions: the frequency has not been established - a short-term tingling sensation, a feeling of hyperemia and burning of the conjunctiva;
- central nervous system: frequency not established - syncope, major epileptic seizure;
- sensory organs: frequency not established - excoriation and keratitis of the corneal surface, damage to the corneal layer of the epithelium;
- cardiovascular system: frequency not established - bradycardia.
Overdose
Data on oxybuprocaine overdose are not provided.
special instructions
Oxybuprocaine should be used only for instillation into the conjunctival sac. The drug should not be used for injection. It is not intended for self-help home therapy.
It should be borne in mind that long-term and repeated treatment with the drug, as well as with other local anesthetics, can cause stable corneal opacity. Oxybuprocaine is not intended for long-term therapy in complex eye pathology.
To avoid contamination when using the dropper bottle, it is important not to touch the tip to any surfaces.
When carrying out anesthesia, it is necessary to protect the eyes from friction, foreign bodies and irritating chemical influences.
Until the end of the anesthesia, it is forbidden to touch the eye.
Patients using contact lenses must remove them before instilling drops. You can resume wearing them only after the signs of anesthesia have completely disappeared.
During the treatment period, it is recommended to exclude alcohol intake.
Influence on the ability to drive vehicles and complex mechanisms
Patients during the period of use of Oxybuprocaine should refrain from driving and engaging in potentially hazardous activities, the implementation of which requires the speed of psychomotor reactions and increased concentration of attention.
Application during pregnancy and lactation
