Corvalol Darnytsia Oral Drops 25 ml – Sedative, Antispasmodic
Corvalol Darnytsia Oral Drops 25 ml is a well-known traditional calming and antispasmodic medicinal solution produced by Pharmaceutical Firm “Darnytsia”. Designed for oral use, this solution combines natural and pharmacological components — including the ethyl ester of α-bromisovaleric acid, phenobarbital and peppermint oil — into a clear, characteristic liquid that supports nervous system balance, mild tension relief and smooth muscle relaxation.
This formulation has a long history of use in Eastern Europe for its ability to produce a gentle calming effect, relieve emotional stress, reduce vasomotor disturbances and manage symptoms associated with mild cardioneurosis, nervous agitation or spasm-related discomfort. While predominantly recognized for its calming action, Corvalol Darnytsia also exerts antispasmodic effects on vascular smooth muscles and may help ease peripheral and coronary vessel tension.
Composition & Mechanism of Action
Each millilitre of Corvalol Darnytsia solution contains key active substances:
-
Ethyl ester of α-bromisovaleric acid: Exhibits a reflex sedative and antispasmodic effect by interacting with receptors in the oral cavity and nasopharynx, subsequently reducing reflex excitability within the central nervous system.
-
Phenobarbital: A barbiturate compound that modulates the reticular activating system, dampening excitatory signals in the brain and producing tranquilizing and calming effects at recommended doses.
-
Peppermint oil: Contains essential oils including menthol that stimulate “cold” receptors, promote reflex vasodilation, and contribute to smooth muscle relaxation, mild digestive support and a refreshing aroma.
Together these components provide a synergistic combination: the ethyl ester helps calm nerve hyperexcitability and smooth muscle tension, phenobarbital enhances inhibitory control in the brain, and peppermint oil adds both calming and antispasmodic benefits with a soothing sensation.
