Lidocaine, eye drops 2% 1.5 ml 5 pcs

Lidocaine is a local anesthetic and antiarrhythmic drug.

The antiarrhythmic activity is due to inhibition of phase 4 (diastolic depolarization) in Purkinje fibers, reduction of automaticity, suppression of ectopic foci of excitation.

The rate of rapid depolarization (phase 0) is not affected or slightly reduced. Increases membrane permeability to potassium ions, accelerates the process of repolarization and shortens the action potential.

It does not change the excitability of the sinus-atrial node and has little effect on conduction and myocardial contractility. When administered intravenously it works quickly and shortly (10-20 min).

The mechanism of local anesthetic effect consists in stabilization of neuronal membrane, reducing its permeability to sodium ions, which prevents the emergence of action potential and impulse conduction.

Possible antagonism with calcium ions. It is rapidly hydrolyzed in a weakly alkaline environment of tissues and after a short latent period is active for 60-90 minutes. During inflammation (tissue acidosis) anesthetic activity decreases. It is effective for all types of local anesthesia. It dilates blood vessels. It has no irritating effect on the tissues.

When using the drug in pharyngeal or nasopharyngeal surgery the pharyngeal reflex is suppressed.

The drug is good at slowing the cough reflex, which can lead to bronchopneumonia, by reaching the larynx and trachea.

The action of lidocaine in aerosol form develops within 1 min and lasts 5-6 min. The desensitization achieved slowly disappears within 15 min.

It is evenly distributed in the body. It penetrates through the placental barrier.

Indications

It is used for anesthesia before:
– measuring intraocular pressure (tonometry);
– gonioscopy;
– diagnostic conjunctival scraping;
– short-term surgical interventions on the cornea and conjunctiva (including removal of foreign bodies and sutures of the cornea and conjunctiva).
– preparation for ophthalmologic surgeries.

How to take, the dosage

Two drops of the solution should be instilled into the conjunctival sac 2-3 times at intervals of 30-60 seconds immediately before the examination or surgical intervention.

Special Instructions

Do not touch the eyes while the product is in action.

Contact lenses should be removed before eye drops are administered; lenses should not be inserted until 30 minutes after injection.

If the side effects after using the drug do not cause discomfort, there are no restrictions on driving vehicles, operating machinery, or engaging in other hazardous activities requiring extra attention and quick responses.

Contraindications

• Sinus node weakness syndrome.
• Developed bradycardia.
• Antrioventricular block of degree 2 and 3 (except when a ventricular simulation probe is inserted).
• Cardiogenic shock.
• Myasthenia gravis.
• High individual sensitivity to lidocaine.
• A history of lidocaine-induced epileptiform seizures.
• Developed impairment of liver function.

When plaster is used in dentistry as an impression material, aerosol is contraindicated because of the risk of aspiration.
