It works by increasing water elimination without losing sodium, helping to correct fluid and electrolyte balance. Our pharmacy provides Tolvaptan in 15mg and 30mg pill strengths for these specialized medical conditions. ## Pricing and Options | Dosage | Pack Size | Price (USD) | Price Per Pill | Status | | :--- | :--- | :--- | :--- | :--- | | **15mg** | 10 pills | **$61.74** | $6.17 | In Stock | | **15mg** | 20 pills | **$121.59** | $6.08 | In Stock | | **15mg** | 30 pills | **$188.99** | $6.30 | In Stock | | **15mg** | 60 pills | **$353.39** | $5.89 | In Stock | | **15mg** | 90 pills | **$521.54** | $5.79 | In Stock | | **15mg** | 120 pills | **$719.99** | $6.00 | In Stock | | **15mg** | 180 pills | **$1008.89** | $5.61 | In Stock | | **30mg** | 10 pills | **$78.84** | $7.89 | In Stock | | **30mg** | 20 pills | **$164.99** | $8.25 | In Stock | | **30mg** | 30 pills | **$232.74** | $7.76 | In Stock | | **30mg** | 60 pills | **$461.69** | $7.70 | In Stock | | **30mg** | 90 pills | **$680.19** | $7.56 | In Stock | | **30mg** | 120 pills | **$891.09** | $7.43 | In Stock | [Buy Now](https://liabilis.com/order-tolvaptan-online-en.html) ## Introduction Tolvaptan is an oral medication approved to treat two distinct conditions: autosomal dominant polycystic kidney disease (ADPKD), where it slows cyst growth and preserves kidney function, and euvolemic hyponatremia caused by the syndrome of inappropriate antidiuretic hormone secretion (SIADH). The active ingredient is Tolvaptan, supplied as a pill in strengths of 15 mg and 30 mg. As a vasopressin V2-receptor antagonist, Tolvaptan promotes free water excretion without significant loss of electrolytes, addressing the underlying water-retention mechanisms of these diseases. --- ## Quick Reference Facts **Active Ingredient** : Tolvaptan **Form** : pill 15 mg | 30 mg **Primary Uses** : • Autosomal dominant polycystic kidney disease (ADPKD) : • Euvolemic hyponatremia (SIADH) --- ## What is Tolvaptan? Tolvaptan is the generic version of medications that contain the active compound Tolvaptan. It belongs to the class of vasopressin V2-receptor antagonists, sometimes called “aquaretics.” In the United States and many other markets the drug is marketed under the brand names **Samsca** (for hyponatremia) and **Jynarque** (for ADPKD). The molecule was first synthesized by the pharmaceutical company Otsuka Pharmaceutical Co., Ltd., which retains the original patents for the branded formulations. Generic Tolvaptan offers the same therapeutic effect as the branded products, meeting rigorous bioequivalence standards set by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). --- ## How Tolvaptan Works Tolvaptan selectively blocks the vasopressin-V2 receptors located on the cells of the renal collecting ducts. Vasopressin (antidiuretic hormone) normally binds these receptors to trigger insertion of aquaporin-2 water channels, promoting reabsorption of free water back into the circulation. By inhibiting this pathway, Tolvaptan reduces water reabsorption, increasing the excretion of dilute urine (aquaresis) while preserving sodium and other electrolytes. In ADPKD, the drug’s aquaretic effect lowers intrarenal cyst fluid pressure, slowing cyst enlargement and preserving glomerular filtration rate. In SIADH-related hyponatremia, the increased free water clearance raises serum sodium concentration, correcting the dilutional hyponatremia. Tolvaptan reaches peak plasma concentrations within 2-4 hours after oral intake and is extensively metabolized by the cytochrome P450 3A4 enzyme. Its elimination half-life is approximately 12 hours, supporting twice-daily dosing for ADPKD and once-daily dosing for hyponatremia. --- ## Conditions Treated with Tolvaptan - **Autosomal Dominant Polycystic Kidney Disease (ADPKD)** Tolvaptan slows the rate of increase in total kidney volume and delays the decline in estimated glomerular filtration rate (eGFR). By reducing cyst growth, it postpones the need for dialysis or transplantation in many patients. - **Euvolemic Hyponatremia (SIADH)** The drug raises serum sodium by promoting excretion of excess free water, correcting the low sodium concentration without causing significant potassium loss. It is used when fluid restriction alone is insufficient or poorly tolerated. Both indications are supported by pivotal Phase III trials-the **TEMPO 3:4** study for ADPKD and the **EVEREST** trial for hyponatremia-demonstrating clinically meaningful outcomes and an acceptable safety profile when monitored appropriately. --- ## Is Tolvaptan the Right Medication for You? Tolvaptan is most suitable for adults who have a confirmed diagnosis of ADPKD with rapidly progressing disease (e.g., eGFR > 30 mL/min/1.73 m² and increasing kidney volume) and who can undergo regular liver-function monitoring. It is also indicated for adults with persistent euvolemic hyponatremia caused by SIADH when conventional measures (fluid restriction, demeclocycline) have failed. Patients with anuria, uncontrolled hepatic impairment, or those taking strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) should generally avoid Tolvaptan. Pregnant or breastfeeding women are advised against use because of potential fetal toxicity. Elderly patients can be treated, but dose adjustments and close monitoring for dehydration are recommended. Ultimately, the decision rests on a physician’s assessment of disease severity, comorbidities, and ability to adhere to required laboratory follow-up. --- ## Buying Tolvaptan from [our online pharmacy](https://liabilis.com/order-tolvaptan-online-en.html) ### Why Choose Our Service?

If more than 12 hours have passed, skip the missed dose and resume your regular schedule; do not double-dose. - **Overdose** Symptoms may include severe dehydration, rapid rise in serum sodium, dizziness, or confusion. Seek emergency medical care promptly. Management focuses on controlled rehydration and monitoring of electrolytes under physician supervision. - **Practical Precautions** • Take Tolvaptan with food to reduce gastrointestinal upset. • Avoid excessive alcohol, which can worsen dehydration. • Do not operate heavy machinery until you know how the drug affects you, especially during the first few days of treatment. --- ## Safety Information ### ⚠️ Who Should Not Take Tolvaptan - Patients with anuria (no urine output). - Individuals with uncontrolled hepatic disease (ALT or AST > 3 × ULN). - Those taking strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) unless dose is reduced under medical guidance. - Pregnant women or women planning pregnancy; Tolvaptan is contraindicated due to teratogenic risk. ### Common Side Effects - **Thirst and dry mouth** - reported in up to 30 % of users; manage by sipping water regularly. - **Polyuria and nocturia** - increased urine volume often leads to more frequent nighttime bathroom trips. - **Constipation** - mild, usually resolves with dietary fiber or over-the-counter stool softeners. ### Serious Side Effects (Seek Immediate Medical Help) - **Liver injury** - elevations in ALT/AST, jaundice, or right-upper-quadrant pain. Routine liver-function tests are required at baseline, monthly for the first 18 months, then quarterly. - **Severe dehydration** - rapid weight loss, dizziness, low blood pressure; may require intravenous fluid replacement. - **Hypernatremia** - serum sodium > 150 mmol/L, causing confusion, seizures, or coma. ### Drug & Food Interactions - **CYP3A4 Inhibitors** (ketoconazole, itraconazole, clarithromycin) → increase Tolvaptan exposure; dose reduction may be necessary. - **CYP3A4 Inducers** (rifampin, carbamazepine, phenytoin) → decrease efficacy; avoid concurrent use. - **Lithium** - Tolvaptan can raise lithium concentrations; monitor serum lithium levels closely. - **Other V2-antagonists** (e.g., conivaptan) → additive aquaretic effect, risk of excessive water loss. - **High-salt meals** - do not offset the drug’s effect; dietary sodium does not need major restriction but maintain a balanced diet. --- ## Off-Label and Investigational Uses of Tolvaptan - **Heart Failure-Related Hyponatremia** - some clinicians use Tolvaptan to correct dilutional hyponatremia in chronic heart failure, supported by small open-label studies showing improved serum sodium without worsening congestion. - **Cirrhotic Ascites** - limited case series suggest Tolvaptan may aid fluid management in patients with liver cirrhosis, but the risk of hepatic injury remains a concern. - **Neuro-critical Care** - experimental protocols have explored its role in managing hyponatremia after subarachnoid hemorrhage, where rapid correction is crucial. These applications are not approved by the FDA or EMA. Use should only occur under the direct supervision of a qualified healthcare professional who can monitor for adverse events and efficacy. --- ## Storage & Handling - Store tablets at a temperature not exceeding 30 °C (86 °F). - Keep the bottle tightly closed, protect from moisture and direct sunlight. - Do not use after the expiration date printed on the packaging. - Dispose of unused medication according to local pharmaceutical waste guidelines or return to a pharmacy take-back program. --- ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Tolvaptan?** Yes, but carry the medication in its original labeled container, bring a copy of the prescribing information, and be aware of each country’s import regulations for prescription drugs. - **Will drinking a lot of water counteract Tolvaptan’s effect?** Excessive fluid intake can diminish the drug’s aquaretic benefit and may increase the risk of hyponatremia reversal.
