Pharmacological properties:
Корвалол® – the calming and spasmolytic drug which effect is defined by the components which are its part.
Ethyl ether of α-bromizovalerianovy acid has the reflex calming and spasmolytic effect caused by irritation preferential of receptors of an oral cavity and a nasopharynx, decrease in reflex irritability in the central parts of the nervous system and strengthening of the phenomena of braking in neurons of bark and subcrustal structures of a brain and also decrease of the activity of the central vasomotor centers and direct local spasmolytic action on smooth muscles of vessels.
Phenobarbital suppresses the activating influences of the centers of a reticular formation of an average and a myelencephalon on bark of big hemispheres, thereby reducing flows of exciting influences on a cerebral cortex and subcrustal structures. Reduction of the activating influences renders, depending on a dose, the calming, tranquilizing or somnolent effect. Корвалол® reduces exciting influences on vasomotor centers, coronary and peripheral vessels, reducing the general arterial pressure, removing and warning vasospasms, especially cordial.
Oil of mint contains a large amount of essential oils, including about 50% of menthol and 4-9% of ethers of menthol. They are capable to irritate "cold" receptors of an oral cavity and to reflex expand preferential vessels of heart and brain, removing spasms of smooth muscles, to cause the calming and easy cholagogue action. Oil of a peppermint has antiseptic and spasmolytic action, has ability to eliminate the meteorism phenomena.
At reception sublingual absorption begins already in hypoglossal area, bioavailability of active agents high (about 60-80%). The effect is shown quickly (in 5-10 minutes). At intake action develops 15-45 minutes later and lasts for 3-6 hours. At persons who accepted drugs of barbituric acid earlier duration of action is reduced due to the accelerated metabolism of phenobarbital in a liver where barbiturates cause induction of enzymes. At people of advanced age and at patients with cirrhosis metabolism of Korvalola® is reduced therefore their elimination half-life is extended that demands reduction of a dose and lengthening of intervals between administrations of drug.

Interaction with other medicines:
Drugs of the central oppressing type of action strengthen action of Korvalola®. Existence in composition of drug of phenobarbital can induce liver enzymes, and it does undesirable its simultaneous use with drugs which are metabolized in a liver (with coumarin derivatives, griseofulvin, glucocorticoids, peroral contraceptives) as their efficiency will decrease as a result of higher metabolic rate. Корвалол® strengthens action mestnoanesteziruyushchy, anesthetizing and hypnagogues, it is connected with the maintenance of derivatives of barbituric acid.
At simultaneous use with valproic acid its effect amplifies.
At simultaneous use with a methotrexate toxicity of the last amplifies.
