⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cholelithiasis and its Complications: Monitor periodically. If complications of cholelithiasis occur, discontinue PALSONIFY and treat appropriately ( 5.1 ). Hyperglycemia and Hypoglycemia: Monitor glucose and adjust antidiabetic treatment as needed ( 5.2 ).
Cardiovascular Abnormalities: Bradycardia or conduction abnormalities may occur. Dosage adjustments of concomitantly used drugs with bradycardia effects may be necessary ( 5.3 ). Thyroid Function Abnormalities: Hypothyroidism may occur.
Assess thyroid function periodically ( 5.4 ). Steatorrhea and Malabsorption of Dietary Fats: New onset steatorrhea, stool discoloration, loose stools, abdominal bloating, and weight loss may occur. If new occurrence or worsening of these symptoms are reported, evaluate for potential pancreatic exocrine insufficiency ( 5.5 ).
Vitamin B 12 Deficiency: Monitor vitamin B 12 levels during treatment if indicated ( 5.6 ).
5.1Cholelithiasis and its Complications PALSONIFY may inhibit gallbladder contractility and decrease bile secretion, which may lead to gallbladder stones or sludge. Cholelithiasis was reported in participants treated with PALSONIFY in clinical trials. Complications of cholelithiasis, such as acute cholecystitis and pancreatitis, have also been reported with the use of PALSONIFY [see Adverse Reactions ( 6.1 )] .
Monitor patients periodically. If complications of cholelithiasis occur, discontinue PALSONIFY and treat appropriately.
5.2Hyperglycemia and Hypoglycemia PALSONIFY may alter the balance between the counter-regulatory hormones, insulin, glucagon, and growth hormone, which may result in hypoglycemia, hyperglycemia, or diabetes mellitus. Hyperglycemia was reported in participants treated with PALSONIFY in clinical trials [see Adverse Reactions ( 6.1 )] . Monitor blood glucose levels when PALSONIFY treatment is initiated or when the dose is altered.
Adjust antidiabetic treatment accordingly.
5.3Cardiovascular Abnormalities Cardiac conduction abnormalities and other ECG changes such as PR interval prolongation have occurred during treatment with PALSONIFY. Bradycardia, sinus arrest, and atrioventricular block were reported in participants treated with PALSONIFY in clinical trials [see Adverse Reactions ( 6.1 )] . These ECG changes may occur in patients with acromegaly.
Dosage adjustments of concomitantly used drugs that have bradycardia effects (e.g., beta-blockers) may be necessary.
5.4Thyroid Function Abnormalities Somatostatin analogs may suppress the secretion of thyroid-stimulating hormone, which may result in hypothyroidism. Periodic assessment of thyroid function (TSH, total, and/or free T 4 ) is recommended during treatment with PALSONIFY.
5.5Steatorrhea and Malabsorption of Dietary Fats New onset steatorrhea, stool discoloration and loose stools have been reported in patients receiving somatostatin analogs. Somatostatin analogs reversibly inhibit secretion of pancreatic enzymes and bile acids, which may result in malabsorption of dietary fats and subsequent symptoms of steatorrhea, loose stools, abdominal bloating, and weight loss. If new occurrence or worsening of these symptoms are reported in patients receiving PALSONIFY, evaluate patients for potential pancreatic exocrine insufficiency and manage accordingly.
5.6Vitamin B 12 Deficiency Decreased vitamin B 12 levels have been observed in patients treated with somatostatin analogs, including PALSONIFY. Monitor vitamin B 12 levels during treatment with PALSONIFY if clinically indicated.

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. The safety of PALSONIFY was evaluated in adults with acromegaly in two randomized, double-blind, placebo-controlled Phase 3 studies. Study 1 was a 24-week, randomized, placebo-controlled study in 111 adults who were naive or previously treated on a somatostatin analog and biochemically uncontrolled at randomization.
Participants in Study 1 had a mean age of 47 years (range: 18 to 80 years) and were randomized to PALSONIFY (n=54) or placebo (n=57) [see Clinical Studies ( 14.1 )] . Study 2 was a 36-week, randomized, placebo-controlled study in 58 adults who were biochemically controlled on injectable depot formulations of octreotide or lanreotide. Participants in Study 2 had a mean age of 55 years (range: 29 to 84 years) and were randomized to PALSONIFY (n=30) or placebo (n=28) [see Clinical Studies ( 14.2 )] .
Adverse Reactions Adverse reactions that occurred in ≥5% of PALSONIFY-treated participants and 5% greater incidence than placebo in the randomized-controlled phase of Study 1 and Study 2 are presented in Table 1 and Table 2 , respectively. Adverse reactions presented in Table 1 and Table 2 exclude events which occurred after a participant received rescue therapy (Study 1 PALSONIFY n=1, placebo n=13; Study 2 PALSONIFY n=1, placebo n=17). Table 1.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Strong CYP3A4 Inducers: may decrease paltusotine exposure. May require PALSONIFY dosage increase ( 2.3 , 7.1 ). Moderate CYP3A4 Inducers: may decrease paltusotine exposure. May require PALSONIFY dosage increase ( 2.3 , 7.1 ). Proton Pump Inhibitors: may decrease paltusotine exposure. May require PALSONIFY dosage increase ( 2.3 , 7.1 ) Cyclosporine: may decrease cyclosporine exposure. May require cyclosporine dosage adjustment ( 7.2 ).
7.1Effect of Other Drugs on PALSONIFY Table 3. Clinically Significant Interactions Affecting PALSONIFY Strong CYP3A4 Inducers Intervention Concomitant use of PALSONIFY with strong CYP3A4 inducers may require an increased dosage of PALSONIFY, not to exceed three-fold the dose prior to concomitant use or 120 mg daily, whichever is less. Clinical Impact Concomitant use of PALSONIFY with strong CYP3A4 inducers reduced paltusotine exposure and may affect therapeutic response [see Clinical Pharmacology ( 12.3 )].
Moderate CYP3A4 Inducers Intervention Concomitant use of PALSONIFY with moderate CYP3A4 inducers may require an increased dosage of PALSONIFY, not to exceed two-fold the dose prior to concomitant use or 120 mg daily, whichever is less. Clinical Impact Concomitant use of PALSONIFY with moderate CYP3A4 inducers resulted in a decrease in paltusotine exposure [see Clinical Pharmacology ( 12.3 )]. Proton Pump Inhibitors Intervention Concomitant use of PALSONIFY with PPIs may require an increased dosage of PALSONIFY.
Patients who are already on PALSONIFY 60 mg should avoid concomitant use with proton pump inhibitors. Clinical Impact Concomitant use of PALSONIFY with proton pump inhibitors demonstrated a dose-dependent decrease in paltusotine exposure [see Clinical Pharmacology ( 12.3 )].
7.2Effect of PALSONIFY on Other Drugs Table 4. Clinically Significant Interactions Affecting Other Drugs Cyclosporine Intervention Adjustment of cyclosporine dose to maintain therapeutic levels may be necessary. Follow recommended therapeutic drug monitoring for cyclosporine. Clinical Impact Concomitant use of PALSONIFY with cyclosporine resulted in a decrease in cyclosporine bioavailability [see Clinical Pharmacology ( 12.3 )].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary The available data with PALSONIFY use in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal reproduction studies, no malformations were observed with oral administration of paltusotine to pregnant rats and rabbits during organogenesis at exposures 11 and 3 times the human exposure at the maximum recommended human dose (MRHD) of 60 mg once daily, respectively (see Data ) . The 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. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal development study in pregnant rats, paltusotine was administered orally at 25, 75, and 500 mg/kg/day during the period of organogenesis from gestation Day 7 to 17.
The NOAEL for maternal and embryo-fetal developmental toxicity was 500 mg/kg/day, as no paltusotine-related effects were observed on any ovarian, uterine or litter parameters (approximately 11 times the MRHD based on AUC). In an embryo-fetal development study in pregnant rabbits, paltusotine was administered orally at 10, 25, and 75 mg/kg/day during the period of organogenesis from gestation Day 7 to 19. Maternal findings included an increased incidence of spontaneous abortions at 75 mg/kg/day, with decreased body weight gain, body weights, and food consumption.
No fetal abnormalities were observed at any dose. Lower fetal body weight was noted at 75 mg/kg/day. The NOAEL for maternal and embryo-fetal developmental toxicity was 25 mg/kg/day (approximately 3 times the MRHD based on AUC).
In a pre- and postnatal development study, pregnant rats were given paltusotine orally at the doses of 25, 75, and 500 mg/kg/day from gestation Day 6 to lactation Day 20. Paltusotine had no effect on the growth and development of offspring up to the highest tested dose of 500 mg/kg (5 times MRHD based on AUC). In a single dose pharmacokinetic study, oral administration of paltusotine at 25 mg/kg or 500 mg/kg paltusotine to pregnant rats showed measurable paltusotine concentrations in embryos and fetuses, demonstrating placental transfer.
Overall, the embryo and fetal concentrations were generally low when compared to maternal concentrations.
8.2Lactation Risk Summary There is no information available on the presence of paltusotine in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Paltusotine is present in animal milk (see Data ). When a drug is present in animal milk, it is likely that the drug will be present in human milk.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for PALSONIFY and any potential adverse effects on the breastfed infant from PALSONIFY or from the underlying maternal condition. Data Paltusotine concentrations were elevated 2.4- to 3.8-fold in rat milk compared to plasma during animal studies. Paltusotine concentrations in plasma and maternal milk suggest that rat pups were likely exposed in utero and/or via lactational transfer.
The concentration of paltusotine in animal milk does not necessarily predict the concentration of paltusotine in human milk.
8.4Pediatric Use The safety and efficacy of PALSONIFY have not been established in pediatric patients.
8.5Geriatric Use In the Phase 3 studies 17/84 (20.2%) PALSONIFY-treated participants were ≥65 years of age. No overall differences in safety or effectiveness of PALSONIFY have been observed between participants 65 years of age and older and younger adult participants. No dose adjustments are required based on age [see Clinical Pharmacology ( 12.3 )] .

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Similar to the natural hormone somatostatin, paltusotine suppresses growth hormone (GH) and insulin-like growth factor-1 (IGF-1) secretion. Paltusotine exerts its pharmacological activity via selective agonism (>4000-fold) at somatostatin receptor 2 (SSTR2) and exhibits little or no affinity for other SST receptor subtypes. Paltusotine inhibited cyclic adenosine monophosphate accumulation via human SSTR2 activation with an average drug (agonist) concentration that results in half-maximal response (EC 50 ) of 0.25 nM.
12.2Pharmacodynamics In patients with acromegaly, there was a dose-dependent reduction in IGF-1 levels over the therapeutic dose range of 20 to 60 mg. Paltusotine may inhibit gallbladder contractility and decrease bile secretion, which may lead to gallbladder stones or sludge [see Warnings and Precautions ( 5.1 )] . Cardiac Electrophysiology At 4.6 times the maximum recommended dose of PALSONIFY, clinically significant QTc interval prolongation was not observed.
12.3Pharmacokinetics Paltusotine exhibited dose-proportional increases in exposures for doses ranging from 20 mg (lowest approved recommended dosage) to 120 mg (2 times the highest approved recommended dosage) in healthy participants. Apparent dose proportional increase was observed for mean steady-state trough concentrations up to 60 mg once daily in participants with acromegaly. Following once daily administration, paltusotine reaches steady-state exposure within one week.
Absorption Following oral administration of paltusotine, the median time to maximum plasma concentration (t max ) is 1 to 4 hours regardless of post dose fasting duration. Effect of Food Relative to administration in the fasted state, administration of paltusotine with a high-fat meal (800 to 1000 calories, 50% to 60% fat) reduced the AUC by 85% and the C max by 81%. Administration of paltusotine with a low-fat meal (400 to 500 calories, 25% fat) reduced AUC by 72% and the C max by 68%.
Distribution The volume of distribution (V z ) of paltusotine is 220 L. Paltusotine is highly plasma protein bound (99%). Elimination After maximal concentrations were attained, paltusotine concentration declined with apparent terminal half-life (t ½ ) of 28 hours.
Metabolism Paltusotine is metabolized primarily in the liver via glucuronidation and oxidation. In vitro, glucuronidation was the major metabolic pathway and is primarily mediated by UGT1A1 and UGT1A9. Oxidation was a secondary pathway and was primarily catalyzed by CYP3A4/5 with a minor contribution from CYP2D6.
Excretion Following oral administration of radiolabeled paltusotine, fecal excretion was the predominant route of elimination with observed mean recovery of total administered radioactivity being 90% in feces and 3.9% in urine. Unchanged paltusotine was a major component in excreta. Specific Populations Effects of Age, Body Weight, Sex, Race , Renal Function , and UGT1A1 Polymorphism Based on population pharmacokinetics data, no clinically significant difference in the pharmacokinetics of paltusotine was observed based on age (18 to 84 years), body weight (45 to 138 kg), sex, race (White, Asian, Other), renal function (52 to 148 mL/min/1.73 m 2 ; eGFR), or UGT1A1 polymorphism.
Hepatic Impairment Paltusotine AUC did not change in participants with mild hepatic impairment (Child-Pugh A) compared to participants with normal hepatic function. Paltusotine AUC decreased by 25% in moderate (Child-Pugh B) and 10% in severe (Child-Pugh C) hepatic impairment. Drug Interaction Clinical Studies and Model-Informed Approaches Effects of Other Drugs on PALSONIFY Strong CYP3A4 Inducers: Paltusotine C max and AUC decreased by approximately 44% and 70%, respectively, following concomitant administration of carbamazepine (a strong inducer of multiple enzymes and transporters [CYP3A4, UGT1A1, and P-gp]).
Moderate CYP3A4 Inducers: Drugs such as efavirenz are predicted to decrease C max and AUC of paltus…
