Stugeron is an antihistamine medication containing the active ingredient cinnarizine. It is primarily used to treat motion sickness and vertigo by reducing nausea and dizziness. The drug works by blocking h1 receptors and also inhibits calcium channels in the central nervous system. By antagonizing histamine receptors it diminishes the perception of motion related signals in the inner ear. Calcium channel blockade reduces neurotransmitter release that would otherwise amplify vestibular disturbances. This combined action stabilizes the vestibular nuclei and improves balance control during travel or rapid head movements. As a result the medication alleviates symptoms such as vertigo and nausea associated with inner ear dysfunction. Cinnarizine's long lasting effect allows sustained relief without the need for frequent dosing.

Stugeron is an oral medication that contains the antihistamine cinnarizine and is used to relieve dizziness and motion-induced nausea. It works by blocking histamine h1 receptors in the vestibular system, which reduces the signals that cause nausea and vertigo. In addition, cinnarizine has a mild calcium-channel blocking effect that improves blood flow to the inner ear and stabilizes the balance centers. This dual action helps the brain interpret movement cues more accurately and decreases the sensation of spinning. Because it targets the pathways involved in motion perception, Stugeron can prevent episodes of vertigo before they become severe. The medication is absorbed from the gut and crosses the blood-brain barrier to reach the central nervous system where it exerts its effects. Its therapeutic role is to restore normal balance perception in situations that trigger dizziness without directly sedating the patient.

Stugeron is an antihistamine that is commonly prescribed for motion sickness and related vertigo. It works by blocking histamine receptors in the brain which helps reduce feelings of nausea. The most frequently reported side effect is drowsiness that may affect concentration. Some users experience dry mouth or a metallic taste after taking the medication. Blurred vision and occasional dizziness have also been noted in clinical observations. Weight gain and mild constipation are reported less often but can occur with long term use. These effects are generally mild and tend to diminish as the body adjusts to the drug.

Stugeron may cause drowsiness or sedation in some users. It can lead to dry mouth as a frequent side effect. Visual disturbances such as blurred vision are reported occasionally. Gastrointestinal symptoms like constipation or stomach upset can occur. Some individuals experience weight gain due to altered appetite. Tremors or mild muscle stiffness have been noted in clinical observations. Headaches sometimes appear during treatment. Dizziness may paradoxically increase in rare cases despite its intended use.
