Usage
This combination medication is primarily prescribed for Ménière’s disease, an inner ear disorder characterized by vertigo (spinning sensation), tinnitus (ringing in the ears), hearing loss, and a feeling of fullness or pressure in the ear. It aims to alleviate these symptoms by improving inner ear blood flow and reducing fluid pressure. Secondary uses include managing cognitive dysfunction and improving cerebral blood circulation.
It is classified as a nootropic and anti-vertigo medication.
The combined mechanism of action involves multiple pathways: Betahistine acts as a histamine analogue, improving inner ear blood flow and reducing endolymphatic pressure. Ginkgo biloba and Vinpocetine enhance cerebral blood flow and possess antioxidant and neuroprotective properties. Piracetam, a nootropic, influences neurotransmission and improves cognitive function. Vitamin D3 is included due to its potential role in inner ear health.
Alternate Names
No formally recognized alternate names exist for this specific five-component combination. It’s often referred to by brand names such as Stablanz-PV, Otolanz PV, Bestflow D, Vertigreat-PVG, Zevert PVG NF, GinkoD3-PVB, and B Citam. Regional variations in brand names may exist within India.
How It Works
Pharmacodynamics: Betahistine influences histamine receptors in the inner ear, promoting vasodilation and reducing endolymphatic pressure, thus alleviating vertigo and associated symptoms. Ginkgo biloba and Vinpocetine improve cerebral blood flow and have antioxidant and neuroprotective effects. Piracetam modulates neurotransmission, potentially enhancing cognitive function. Vitamin D3 plays a role in calcium homeostasis and may contribute to inner ear health.
Pharmacokinetics: The individual components have different pharmacokinetic profiles. Betahistine is rapidly absorbed and metabolized, primarily via hepatic routes. Ginkgo biloba components have variable absorption and are metabolized by CYP enzymes. Piracetam is well-absorbed and excreted largely unchanged by the kidneys. Vinpocetine is metabolized in the liver. Vitamin D3 undergoes hepatic and renal metabolism.
Mode of Action: Betahistine acts on histamine receptors (H1 agonist, H3 antagonist) in the inner ear. Ginkgo biloba contains flavonoids and terpenoids with antioxidant and anti-inflammatory properties. Piracetam’s mechanism is not fully understood, but it may modulate neurotransmitter release and improve cerebral blood flow. Vinpocetine inhibits phosphodiesterase and may enhance cerebral oxygen utilization. Vitamin D3 regulates calcium and phosphate homeostasis. Elimination occurs via both hepatic and renal pathways for most components.
Dosage
Dosage guidelines for this specific combination are not standardized and can vary based on brand and individual patient factors. Always refer to the specific product’s prescribing information. The following represents a general overview based on available information and should not be considered definitive medical advice.
Standard Dosage
Children: Use in children and adolescents under 18 is generally not recommended due to a lack of safety and efficacy data.
Special Cases: Dosage adjustments may be necessary for elderly patients, individuals with renal or hepatic impairment, and those with comorbid conditions. These adjustments should be made on a case-by-case basis under the guidance of a physician.
Clinical Use Cases
The combination is not specifically indicated for procedures such as Intubation, Surgical Procedures, Mechanical Ventilation, Intensive Care Unit (ICU) use, or Emergency Situations (e.g., status epilepticus, cardiac arrest).
Dosage Adjustments
Dose modification is determined by patient-specific factors (renal/hepatic dysfunction, metabolic disorders, drug metabolism affecting genetic polymorphisms). A physician should determine the specific adjustment based on individual characteristics.
Side Effects
Common Side Effects
Nausea, headache, indigestion, bloating, stomach upset, heartburn, dizziness, nervousness, insomnia, weight gain, skin rash, and flushing.
Rare but Serious Side Effects
Allergic reactions (skin rash, itching, swelling, difficulty breathing), severe dizziness, and worsening of pre-existing conditions (e.g., asthma, peptic ulcers).
Long-Term Effects
The potential long-term effects of this combination are not well-studied.
Adverse Drug Reactions (ADR)
Serious ADRs are rare but could include anaphylaxis (a severe allergic reaction). Any signs of hypersensitivity should be treated as a medical emergency.
Contraindications
Hypersensitivity to any component, bleeding disorders, history of seizures, pheochromocytoma.
Drug Interactions
This combination can interact with various medications, including anticoagulants (warfarin, heparin, aspirin), antiplatelet drugs (clopidogrel), antihistamines, monoamine oxidase inhibitors (MAOIs), antidepressants (fluoxetine), anticonvulsants (phenytoin, carbamazepine), cholesterol-lowering medications (statins), and medications for HIV/AIDS. Alcohol can increase the risk of side effects and should be avoided or consumed with caution. Other potential interactions include those with certain OTC drugs, supplements, and foods (e.g., grapefruit juice). It is important to disclose all medications and supplements being taken to avoid potential interactions.
Pregnancy and Breastfeeding
Use during pregnancy and breastfeeding is generally not recommended due to limited safety data. The potential risks to the fetus or nursing infant outweigh the potential benefits. Safer alternative treatments should be considered.
Drug Profile Summary

Popular Combinations
This combination itself is considered a “popular” combination in some clinical settings addressing Ménière’s disease and cognitive dysfunction. There are no widely established additional drug combinations regularly added to this specific five-component formulation. However, a physician might prescribe additional medications to address specific symptoms or underlying conditions, based on the individual patient’s needs.
Precautions
Pre-screening for allergies, bleeding disorders, seizure disorders, and other relevant medical conditions is essential. Patients should avoid driving or operating machinery if experiencing dizziness or drowsiness. Dietary restrictions and interactions with specific foods haven’t been definitively established for the combination. Patients should maintain a healthy, balanced diet.
