Medication "Ultracain" refers to local anesthetics. The active substance is articaine hydrochloride. The drug blocks sodium channels in the neuron membrane, which provokes a decrease in impulses along nerve fibers. This is what determines the local anesthetic effect of Ultracain. As a result of the activity of the drug, a reversible loss of sensitivity occurs due to a decrease or elimination of the conductivity of sensory impulses in the injection area or directly at the injection site. Due to its ability to reduce permeability in the membranes of nerve cells, the drug has a membrane-stabilizing effect. The active substance passes the placental barrier, is practically not found in milk.
The drug "Ultracain". Instruction Indications
The medicine is used for conduction and infiltration anesthesia during operations in dentistry. In particular, the medication is effective in the simple removal of several or one tooth, the processing of carious cavities, grinding of teeth before prosthetics.
Means "Ultracain". Instructions for use
The dosage for adults is 4-6 mg / kg. Allowed the introduction of not more than 400 mg. To carry out infiltration anesthesia , as a rule, 1.7 ml is injected (in the absence of inflammation) into two adjacent or one tooth. Approximately 1-1.7 ml is required to freeze the alveolar nerve. Before injections, an aspiration test should be performed to avoid intravascular (unintentional) administration of the drug.
The drug "Ultracain". Instruction Adverse reactions
Adverse events from the central nervous system are usually dose-dependent. Stupor occurs in patients, in some cases leading to loss of
consciousness, respiratory
disorders causing it to stop,
muscle twitching, tremor were noted. The tool causes paresthesia, dizziness, transient visual disturbances (double vision, blindness, turbidity before the eyes). Sometimes nerve damage occurs, provoked by a violation of the drug administration technique. In these cases, the development
of facial paralysis is likely
. A medication can cause a digestive tract dysfunction, nausea, allergic reactions. With injections, the development of skin hyperemia, angioedema, and rhinitis is likely. The medicine can cause difficulty in swallowing, shock, heart failure, low blood pressure, bradycardia. Swelling of the tissue or inflammation on the mucosa is possible at the injection site.
Means "Ultracain". Instruction Contraindications
The medicine is not used for hypoxia, in childhood (up to four years), with anemia. The drug "Ultracain" is not prescribed for methemoglobinemia, severe arterial hypotension. Contraindications include decompensated heart failure in the acute course, hypersensitivity to the components. The drug is not recommended for disorders of conduction and sinus node functions. In particular, contraindications include bradycardia of a pronounced nature,
atrioventricular block. The drug "Ultracainum" (reviews of experts confirm this) should be used with caution in case of cholinesterase deficiency. In this case, the medicine is used only when absolutely necessary, due to the likelihood of too strong and prolonged activity.
