Vertina® Plus tablet: Each film coated tablet contains Meclizine Hydrochloride USP 25 mg and Pyridoxine Hydrochloride BP 50 mg.
Meclizine Hydrochloride is a piperazine-derivative antihistamine that is used as an antiemetic. It has antiemetic, anticholinergic and antihistaminic properties. It exhibits its action by an effect on CNS, possibly by its ability to block muscarinic receptors in the brain. It has marked effects in blocking the vasodepressor response to histamine, but only a slight blocking action against acetylcholine. It reduces the sensitivity of the labyrinthine apparatus. The site and mechanism of action of Meclizine Hydrochloride in controlling vertigo from various conditions have not been clearly defined. Pyridoxine Hydrochloride (Vit-B₆), either alone or in combination has been used to prevent nausea and vomiting due to its antiemetic properties.
For prophylaxis and symptomatic relief of nausea, vomiting, dizziness, motion sickness, radiation sickness and vertigo associated with diseases of vestibular system (e.g. Meniere’s syndrome, labyrinthitis and other vestibular disturbances) and morning sickness during pregnancy.
The fixed-dose combination is recommended for oral administration.
There may be increased CNS depression when Meclizine Hydrochloride and Pyridoxine Hydrochloride is administered concurrently with other CNS depressants, including benzodiazepines, barbiturates, tricyclic antidepressants, opiate agonists, skeletal muscle relaxants, antihistamines, alcohol & tranquilizers. Meclizine Hydrochloride can increase the absorption of digoxin by decreasing gastrointestinal motility. MAO inhibitors may prolong and intensify the anticholinergic effects of Meclizine Hydrochloride.
OVERDOSAGE:
Symptoms: Extreme excitability, seizure, drowsiness, temporary nerve damage & hallucination.
Treatment: Appropriate supportive and symptomatic treatment. Dialysis may be a treatment option also.
Although Meclizine Hydrochloride may excrete into breast milk, it causes no harm in nursing babies.
Due to its potential anticholinergic action, patients with asthma, bronchitis, emphysema, enlarged prostate, glaucoma or urinary tract blockade should take Meclizine Hydrochloride (like other antiemetics) with caution.
Store below 30°C, away from light & moisture. Keep out of the reach and sight of children.
