- active substances: ethyl bromisovalerianate (ethyl ester of α-bromisovaleric acid) (in terms of 100% substance) - 20 mg, phenobarbital - 18 mg, mint oil - 1.4 mg, hop oil - 0.2 mg;

Pharmacological properties
Pharmacodynamics
Corvaldin is a sedative with an antispasmodic effect. Its action is due to the properties of its constituent components.
The sedative and antispasmodic effect of ethyl bromisovalerianate is determined by its ability to irritate the receptors of the nasopharynx and the oral cavity, reduce reflex excitability in the central parts of the nervous system, increase inhibition in the neurons of the cortex and subcortical structures of the brain, reduce the activity of vasomotor centers, and exert an antispasmodic effect on smooth musculature.
Phenobarbital enhances the sedative effect of ethyl bromisovalerianate, in addition, thanks to it, the excitation of the central nervous system (CNS) is reduced and the onset of sleep is facilitated.
Peppermint oil and hop oil have reflex vasodilating and antispasmodic effects, irritating the cold receptors in the oral cavity, providing a mild choleretic effect and eliminating flatulence.
Pharmacokinetics
Phenobarbital is rapidly absorbed. The connection with plasma proteins is 35%. Reabsorption occurs at low pH levels. The alkalinity of the urine prevents back diffusion. A small part of the dose taken undergoes oxidation in the liver, about 30% is excreted unchanged in the urine.
Bromine and ethyl bromisovalerianate are slowly excreted from the body, as a result of which, with prolonged use, the risk of chronic intoxication with bromine increases.
Indications for use
- neurosis with increased irritability, anxiety, fear;
- insomnia and difficulty falling asleep;
- spasms of the coronary vessels (mild), tachycardia;
- state of arousal with pronounced autonomic reactions;
- vegetative-vascular dystonia and hypertension (as part of complex therapy);

The daily dose of the drug (90 drops) contains 1.62 g of absolute ethyl alcohol.
The presence of phenobarbital in the drug increases the risk of developing Stevens-Johnson and Lyell syndromes, especially in the first weeks of treatment.
