⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypernatremia, dehydration and hypovolemia: May require intervention ( 5.3 )
5.1Serious Liver Injury Tolvaptan tablets can cause serious and potentially fatal liver injury. Acute liver failure requiring liver transplantation has been reported in the post-marketing ADPKD experience. Discontinuation in response to laboratory abnormalities or signs or symptoms of liver injury (such as fatigue, anorexia, nausea, right upper abdominal discomfort, vomiting, fever, rash, pruritus, icterus, dark urine or jaundice) can reduce the risk of severe hepatotoxicity.
In a 3-year placebo-controlled trial and its open-label extension (in which patients' liver tests were monitored every 4 months), evidence of serious hepatocellular injury (elevations of hepatic transaminases of at least 3 times ULN combined with elevated bilirubin at least 2 times the ULN) occurred in 0.2% (3/1487) of tolvaptan treated patients compared to none of the placebo treated patients. To reduce the risk of significant or irreversible liver injury, assess ALT, AST and bilirubin prior to initiation of tolvaptan tablets, at 2 weeks and 4 weeks after initiation, then monthly for 18 months and every 3 months thereafter.
At the onset of signs or symptoms consistent with hepatic injury or if ALT, AST, or bilirubin increase to >2 times ULN, immediately discontinue tolvaptan tablets, obtain repeat tests as soon as possible (within 48 to 72 hours), and continue testing as appropriate. If laboratory abnormalities stabilize or resolve, tolvaptan tablets may be reinitiated with increased frequency of monitoring as long as ALT and AST remain below 3 times ULN. Do not restart tolvaptan tablets in patients who experience signs or symptoms consistent with hepatic injury or whose ALT or AST ever exceeds 3 times ULN during treatment with tolvaptan, unless there is another explanation for liver injury and the injury has resolved.
In patients with a stable, low baseline AST or ALT, an increase above 2 times baseline, even if less than 2 times upper limit of normal, may indicate early liver injury. Such elevations may warrant treatment suspension and prompt (48 to 72 hours) re-evaluation of liver test trends prior to reinitiating therapy with more frequent monitoring.
5.2Tolvaptan for ADPKD Shared System REMS Tolvaptan tablets are available only through a restricted distribution program under a Risk Evaluation and Mitigation Strategy (REMS) called the Tolvaptan for ADPKD Shared System REMS, because of the risks of liver injury [see Warnings and Precautions ( 5.1 )] . Notable requirements of the Tolvaptan for ADPKD Shared System REMS include the following: Prescribers must be certified by enrolling in the REMS program. Prescribers must inform patients receiving tolvaptan tablets about the risk of hepatotoxicity associated with its use and how to recognize the signs and symptoms of hepatotoxicity and the appropriate actions to take if it occurs.
Patients must enroll in the REMS program and comply with ongoing monitoring requirements [see Warnings and Precautions ( 5.1 )] . Pharmacies must be certified by enrolling in the REMS program and must only dispense to patients who are authorized to receive tolvaptan tablets. Further information, including a list of qualified pharmacies/distributors, is available at www.TolvaptanADPKDSharedREMS.com or by telephone at 1-866-244-9446.
5.3Hypernatremia, Dehydration and Hypovolemia Tolvaptan tablets increase free water clearance and, as a result, may cause dehydration, hypovolemia and hypernatremia. Therefore, ensure abnormalities in sodium concentrations are corrected prior to initiation of therapy. Instruct patients to drink water when thirsty, and throughout the day and night if awake.
Monitor for weight loss, tachycardia and hypotension because they may signal dehydration. In the two double-blind, placebo-controlled trials of patients with ADPKD, hypernatremia (defined as any serum sodium concentration >150 mEq/L) was obser…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Tolvaptan tablets have been studied in over 3000 patients with ADPKD. Long-term, placebo-controlled safety information of tolvaptan tablets in ADPKD is principally derived from two trials where 1,413 subjects received tolvaptan and 1,098 received placebo for at least 12 months across both studies.
TEMPO 3:4 -NCT00428948: A Phase 3, Double-Blind, Placebo-Controlled, Randomized Trial in Early, Rapidly-Progressing ADPKD The TEMPO 3:4 trial employed a two-arm, 2:1 randomization to tolvaptan or placebo, titrated to a maximally-tolerated total daily dose of 60 to 120 mg. A total of 961 subjects with rapidly progressing ADPKD were randomized to tolvaptan tablets. Of these, 742 (77%) subjects who were treated with tolvaptan tablets remained on treatment for at least 3 years.
The average daily dose in these subjects was 96 mg daily. Adverse events that led to discontinuation were reported for 15.4% (148/961) of subjects in the tolvaptan tablets group and 5% (24/483) of subjects in the placebo group. Aquaretic effects were the most common reasons for discontinuation of tolvaptan tablets.
These included pollakiuria, polyuria, or nocturia in 63 (6.6%) subjects treated with tolvaptan tablets compared to 1 subject (0.2%) treated with placebo. Table 2 lists the adverse reactions that occurred in at least 3% of ADPKD subjects treated with tolvaptan tablets and at least 1.5% more than on placebo.

During the tolvaptan tablets titration and run-in period, 126 (8.4%) of the 1496 subjects discontinued the study, 52 (3.5%) were due to aquaretic effects and 10 (0.7%) were due to liver test findings. Because of this run-in design, the adverse reaction rates observed during the randomized period are not described.

7 DRUG INTERACTIONS Avoid concomitant use with: Strong CYP 3A Inducers ( 7.1 ) V 2 -Receptor Agonists ( 7.2 )
7.1CYP 3A Inhibitors and Inducers CYP 3A Inhibitors Tolvaptan's AUC was 5.4 times as large and C max was 3.5 times as large after co-administration of tolvaptan and 200 mg ketoconazole [see Warnings and Precautions ( 5.4 ) and Clinical Pharmacology ( 12.3 ) ] . Larger doses of the strong CYP 3A inhibitor would be expected to produce larger increases in tolvaptan exposure. Concomitant use of tolvaptan with strong CYP 3A inhibitors is contraindicated [see Contraindications ( 4 ) ].
Dose reduction of tolvaptan tablets is recommended for patients while taking moderate CYP 3A inhibitors [see Dosage and Administration ( 2.4 ) ]. Patients should avoid grapefruit juice beverages while taking tolvaptan tablets. Strong CYP 3A Inducers Co-administration of tolvaptan tablets with strong CYP 3A inducers reduces exposure to tolvaptan tablets [see Clinical Pharmacology ( 12.3 ) ].
Avoid concomitant use of tolvaptan tablets with strong CYP 3A inducers [see Dosage and Administration ( 2.4 ) ].
7.2V 2 -Receptor Agonist As a V 2 -receptor antagonist, tolvaptan will interfere with the V 2 -agonist activity of desmopressin (dDAVP). Avoid concomitant use of tolvaptan tablets with a V 2 -agonist.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm ( 8.1 ) Lactation: Breastfeeding not recommended ( 8.2 )
8.1Pregnancy Risk Summary Available data with tolvaptan tablets use in pregnant women are insufficient to determine if there is a drug associated risk of adverse developmental outcomes. In embryo-fetal development studies, pregnant rats and rabbits received oral tolvaptan during organogenesis. At maternally non-toxic doses, tolvaptan did not cause any developmental toxicity in rats or in rabbits at exposures approximately 4- and 1-times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 90/30 mg.
However, effects on embryo-fetal development occurred in both species at maternally toxic doses. In rats, reduced fetal weights and delayed fetal ossification occurred at 17-times the human exposure. In rabbits, increased abortions, embryo-fetal death, fetal microphthalmia, open eyelids, cleft palate, brachymelia and skeletal malformations occurred at approximately 3-times the human exposure (see Data).
Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
The estimated background risk of major birth defects and miscarriage in the U.S. general population is 2 to 4% and 15 to 20% of clinically recognized pregnancies, respectively. Data Animal Data: Oral administration of tolvaptan during the period of organogenesis in Sprague-Dawley rats produced no evidence of teratogenesis at doses up to 100 mg/kg/day. Lower body weights and delayed ossification were seen at 1000 mg/kg, which is approximately 17-times the exposure in humans at the 90/30 mg dose (AUC 24h 6570 h·ng/mL).
The fetal effects are likely secondary to maternal toxicity (decreased food intake and low body weights). In a prenatal and postnatal study in rats, tolvaptan had no effect on physical development, reflex function, learning ability or reproductive performance at doses up to 1000 mg/kg/day. In New Zealand White rabbits, placental transfer was demonstrated with C max values in the yolk sac fluid approximating 22.7% of the value in maternal rabbit serum.
In embryo-fetal studies, teratogenicity (microphthalmia, embryo-fetal mortality, cleft palate, brachymelia and fused phalanx) was evident in rabbits at 1000 mg/kg (approximately 3 times the exposure at the 90/30 mg dose). Body weights and food consumption were lower in dams at all doses, equivalent to 0.6 to 3-times the human exposure at the 90/30 mg dose.
8.2Lactation Risk Summary There are no data on the presence of tolvaptan in human milk, the effects on the breastfed infant, or the effects on milk production. Tolvaptan is present in rat milk. When a drug is present in animal milk, it is possible that the drug will be present in human milk, but relative levels may vary (see Data) .
Because of the potential for serious adverse reactions, including liver toxicity, electrolyte abnormalities (e.g., hypernatremia), hypotension, and volume depletion in breastfed infants, advise women not to breastfeed during treatment with tolvaptan tablets. Data In lactating rats administration of radiolabeled tolvaptan, lacteal radioactivity concentrations reached the highest level at 8 hours after administration and then decreased gradually with time with a half-life of 27.3 hours. The level of activity in milk ranged from 1.5- to 15.8-fold those in blood over the period of 72 hours post-dose.
In a prenatal and postnatal study in rats, maternal toxicity was noted at 100 mg/kg/day or higher (≥4.4 times the human exposure at the 90/30 mg dose). Increased perinatal death and decreased body weight of the offspring were observed during the lactation period and after weaning at approximately 17.3 times the human exposure at the 90/30 mg dose.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of tolvaptan tablets in pediatric patients have not been established.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of tolvaptan did not include sufficient numbers of subjects aged 65 years old and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Single oral doses up to 480 mg (4 times the maximum recommended daily dose) and multiple doses up to 300 mg once daily for 5 days have been well tolerated in trials in healthy subjects. There is no specific antidote for tolvaptan intoxication. The signs and symptoms of an acute overdose can be anticipated to be those of excessive pharmacologic effect: a rise in serum sodium concentration, polyuria, thirst, and dehydration/hypovolemia.
No mortality was observed in rats or dogs following single oral doses of 2000 mg/kg (maximum feasible dose). A single oral dose of 2000 mg/kg was lethal in mice, and symptoms of toxicity in affected mice included decreased locomotor activity, staggering gait, tremor and hypothermia. In patients with suspected tolvaptan tablets overdosage, assessment of vital signs, electrolyte concentrations, ECG and fluid status is recommended.
Continue replacement of water and electrolytes until aquaresis abates. Dialysis may not be effective in removing tolvaptan tablets because of its high binding affinity for human plasma protein (>98%).
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Tolvaptan is a selective vasopressin V 2 -receptor antagonist with an affinity for the V 2 -receptor that is 1.8 times that of native arginine vasopressin (AVP). Tolvaptan affinity for the V 2 -receptor is 29 times that for the V 1a - receptor. Decreased binding of vasopressin to the V 2 -receptor in the kidney lowers adenylate cyclase activity resulting in a decrease in intracellular adenosine 3′, 5′-cyclic monophosphate (cAMP) concentrations.
Decreased cAMP concentrations prevent aquaporin 2 containing vesicles from fusing with the plasma membrane, which in turn causes an increase in urine water excretion, an increase in free water clearance (aquaresis) and a decrease in urine osmolality. In human ADPKD cyst epithelial cells, tolvaptan inhibited AVP- stimulated in vitro cyst growth and chloride-dependent fluid secretion into cysts. In animal models, decreased cAMP concentrations were associated with decreases in the rate of growth of total kidney volume and the rate of formation and enlargement of kidney cysts.
Tolvaptan metabolites have no or weak antagonist activity for human V 2 -receptors compared with tolvaptan.
12.2Pharmacodynamics In healthy subjects or patients with eGFRs as low as 10 mL/min/1.73 m 2 receiving a single dose of tolvaptan, the onset of the aquaretic effects occurs within 1 to 2 hours post-dose. In healthy subjects, single doses of 60 mg and 90 mg produce a peak effect of about a 9 mL/min increase in urine excretion rate is observed between 4 and 8 hours post-dose. Higher doses of tolvaptan do not increase the peak effect in urine excretion rate but sustain the effect for a longer period of time.
Urine excretion rate returns to baseline within 24 hours following the maximum recommended 90 mg dose of tolvaptan. Changes in free water clearance mirror the changes in urine excretion rate. Increased free water clearance causes an increase in serum sodium concentration unless fluid intake is increased to match urine output.
Increases in urine excretion rate and free water clearance are positively correlated with baseline glomerular filtration rate with increases in both values observed in patients with creatinine clearance as low as 15 mL/min. With the recommended split-dose regimens, tolvaptan inhibits vasopressin from binding to the V 2 -receptor in the kidney for the entire day, as indicated by increased urine output and decreased urine osmolality. Following a 90/30 mg split-dose regimen in patients with eGFR >60 mL/min/1.73 m 2 , the change in mean daily urine volume was about 4 L for a mean total daily volume of about 7 L.
In patients with eGFR <30 mL/min/1.73 m 2 , the mean change in daily urine volume was about 2 L for a total daily urine volume of about 5 L. Plasma concentrations of native AVP may increase (avg. 2 to 9 pg/mL) with tolvaptan treatment and return to baseline levels when treatment is stopped.
During tolvaptan treatment, small changes in renal function are expected and the changes are independent of baseline renal function. Glomerular filtration rate is decreased about 6% to 10% and uric acid clearance is decreased about 20% to 25%. Percent changes in renal plasma flow are highly correlated to percent changes in GFR.
These changes are reversed upon discontinuation of tolvaptan. Cardiac Electrophysiology No prolongation of the QT interval was observed with tolvaptan following multiple doses of 300 mg/day for 5 days.
12.3Pharmacokinetics In healthy subjects, the pharmacokinetics of tolvaptan after single doses of up to 480 mg and multiple doses up to 300 mg once daily have been studied. In ADPKD patients, single doses up to 120 mg and multiple split-doses up to 90/30 mg have been studied. Absorption In healthy subjects, peak concentrations of tolvaptan are observed between 2 and 4 hours post-dose.
Peak concentrations increase less than dose proportionally with doses greater than 240 mg. The absolute bioavailability of tolvaptan decreases w…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Tolvaptan is a selective vasopressin V 2 -receptor antagonist with an affinity for the V 2 -receptor that is 1.8 times that of native arginine vasopressin (AVP). Tolvaptan affinity for the V 2 -receptor is 29 times that for the V 1a - receptor. Decreased binding of vasopressin to the V 2 -receptor in the kidney lowers adenylate cyclase activity resulting in a decrease in intracellular adenosine 3′, 5′-cyclic monophosphate (cAMP) concentrations.
Decreased cAMP concentrations prevent aquaporin 2 containing vesicles from fusing with the plasma membrane, which in turn causes an increase in urine water excretion, an increase in free water clearance (aquaresis) and a decrease in urine osmolality. In human ADPKD cyst epithelial cells, tolvaptan inhibited AVP- stimulated in vitro cyst growth and chloride-dependent fluid secretion into cysts. In animal models, decreased cAMP concentrations were associated with decreases in the rate of growth of total kidney volume and the rate of formation and enlargement of kidney cysts.
Tolvaptan metabolites have no or weak antagonist activity for human V 2 -receptors compared with tolvaptan.
