⛔ Contraindications ▾
4 CONTRAINDICATIONS Lubiprostone is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction [see Warnings and Precautions ( 5.5 )] . Patients with known or suspected mechanical gastrointestinal obstruction. ( 4 , 5.5 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Nausea: Patients may experience nausea; concomitant administration of food may reduce this symptom. ( 2.2 , 5.1 ) Diarrhea: Avoid use in patients with severe diarrhea. Instruct patients to discontinue lubiprostone and contact their healthcare provider if severe diarrhea occurs during treatment.
( 5.2 ) Syncope and Hypotension: May occur after taking the first dose or with subsequent doses. Generally resolves prior to the next dose, but may recur with repeat dosing. Instruct patients to discontinue lubiprostone and contact their healthcare provider if symptoms occur.
( 5.3 ) Dyspnea: May occur within an hour of first dose. Generally resolves within 3 hours, but may recur with repeat dosing. Instruct patients to contact their healthcare provider if symptoms occur.
( 5.4 ) Bowel Obstruction: Evaluate patients with symptoms suggestive of mechanical gastrointestinal obstruction prior to initiating treatment with lubiprostone. ( 4 , 5.5 )
5.1Nausea Patients taking lubiprostone may experience nausea. Concomitant administration of food with lubiprostone may reduce symptoms of nausea [see Adverse Reactions ( 6.1 )] .
5.2Diarrhea Avoid use of lubiprostone in patients with severe diarrhea. Patients should be aware of the possible occurrence of diarrhea during treatment. Instruct patients to discontinue lubiprostone and contact their healthcare provider if severe diarrhea occurs [see Adverse Reactions ( 6.1 )] .
5.3Syncope and Hypotension Syncope and hypotension have been reported with lubiprostone in the postmarketing setting and a few of these adverse reactions resulted in hospitalization. Most cases occurred in patients taking 24 mcg twice daily and some occurred within an hour after taking the first dose or subsequent doses of lubiprostone. Some patients had concomitant diarrhea or vomiting prior to developing the adverse reaction.
Syncope and hypotension generally resolved following lubiprostone discontinuation or prior to next dose, but recurrence has been reported with subsequent doses. Several cases reported concomitant use of medications known to lower blood pressure, which may increase the risk for the development of syncope or hypotension. Patients should be aware of the risk of syncope and hypotension during treatment and that other adverse reactions may increase this risk, such as diarrhea or vomiting.
5.4Dyspnea In clinical trials, dyspnea was reported by 3%, 1%, and < 1% of the treated CIC, OIC, and IBS-C populations receiving lubiprostone, respectively, compared to 0%, 1%, and < 1% of placebo-treated patients. There have been postmarketing reports of dyspnea when using lubiprostone 24 mcg twice daily. Some patients have discontinued treatment because of dyspnea.
These events have usually been described as a sensation of chest tightness and difficulty taking in a breath, and generally have an acute onset within 30 to 60 minutes after taking the first dose. They generally resolve within a few hours after taking the dose, but recurrence has been frequently reported with subsequent doses. Instruct patients to contact their healthcare provider if dyspnea occurs.
5.5Bowel Obstruction In patients with symptoms suggestive of mechanical gastrointestinal obstruction, perform a thorough evaluation to confirm the absence of an obstruction prior to initiating therapy with lubiprostone [see Contraindications ( 4 )] .
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions are described below and elsewhere in labeling: Nausea [see Warnings and Precautions ( 5.1 )] Diarrhea [see Warnings and Precautions ( 5.2 )] Syncope and Hypotension [see Warnings and Precautions ( 5.3 )] Dyspnea [see Warnings and Precautions ( 5.4 )] Most common adverse reactions (> 4%) are: CIC: nausea, diarrhea, headache, abdominal pain, abdominal distension, and flatulence. ( 6.1 ) OIC: nausea and diarrhea. ( 6.1 ) IBS-C: nausea, diarrhea, and abdominal pain.

6.1Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. During clinical development of lubiprostone for CIC, OIC, and IBS-C, 1,648 patients were treated with lubiprostone for 6 months and 710 patients were treated for 1 year (not mutually exclusive). Chronic Idiopathic Constipation Adverse reactions in adult dose-finding, efficacy, and long-term clinical studies: The data described below reflect exposure to lubiprostone 24 mcg twice daily in 1,113 patients with CIC over 3- or 4-week, 6-month, and 12-month treatment periods; and from 316 patients receiving placebo over short-term exposure (≤ 4 weeks).
The placebo population (N = 316) had a mean age of 48 (range 21 to 81) years; was 87% female; 81% Caucasian, 10% African American, 7% Hispanic, 1% Asian, and 12% elderly (≥ 65 years of age). Of those patients treated with lubiprostone 24 mcg twice daily (N=1,113), the mean age was 50 (range 19 to 86) years; 87% were female; 86% Caucasian, 8% African American, 5% Hispanic, 1% Asian, and 17% elderly (≥ 65 years of age). The most common adverse reactions (> 4%) in CIC were nausea, diarrhea, headache, abdominal pain, abdominal distension, and flatulence.
Table 2 presents data for the adverse reactions that occurred in at least 1% of patients and that occurred more frequently with lubiprostone than placebo. Table 2 Adverse Reactions 1 in Clinical Trials of Adults with CIC 1 Reported in at least 1% of patients treated with lubiprostone and greater than placebo 2 This term combines "abdominal tenderness," "abdominal rigidity," "gastrointestinal discomfort," "stomach discomfort", and "abdominal discomfort." System/Adverse Reaction Placebo N = 316 % Lubiprostone 24 mcg Twice Daily N = 1,113 % Nausea 3 29 Diarrhea 1 12 Headache 5 11 Abdominal pain 3 8 Abdominal distension 2 6 Flatulence 2 6 Vomiting 0 3 Loose stools 0 3 Edema < 1 3 Abdominal discomfort 2 1 3 Dizziness 1 3 Chest discomfort/pain 0 2 Dyspnea 0 2 Dyspepsia < 1 2 Fatigue 1 2 Dry mouth < 1 1 Nausea: Approximately 29% of patients who received lubiprostone experienced nausea; 4% of patients had severe nausea and 9% of patients discontinued treatment due to nausea.
The rate of nausea was lower among male (8%) and elderly (19%) patients. No patients in the clinical studies were hospitalized due to nausea. Diarrhea: Approximately 12% of patients who received lubiprostone experienced diarrhea; 2% of patients had severe diarrhea and 2% of patients discontinued treatment due to diarrhea.
Electrolytes: No serious adverse reactions of electrolyte imbalance were reported in clinical studies, and no clinically significant changes were seen in serum electrolyte levels in patients receiving lubiprostone. Less common adverse reactions (< 1%): fecal incontinence, muscle cramp, defecation urgency, frequent bowel movements, hyperhidrosis, pharyngolaryngeal pain, intestinal functional disorder, anxiety, cold sweat, constipation, cough, dysgeusia, eructation, influenza, joint swelling, myalgia, pain, syncope, tremor, decreased appetite.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Methadone Diphenylheptane opioids (e.g., methadone) have been shown in nonclinical studies to dose-dependently reduce the activation of ClC-2 by lubiprostone in the gastrointestinal tract. There is a possibility of a dose-dependent decrease in the efficacy of lubiprostone in patients using diphenylheptane opioids. No in vivo interaction studies have been conducted.
The effectiveness of lubiprostone in the treatment of OIC in patients taking diphenylhepatane opioids (e.g., methadone) has not been established [see Indications and Usage ( 1.2 )] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 ) Pediatrics: Safety and effectiveness have not been established in pediatric patients with IBS-C, pediatric functional constipation (PFC), and OIC. ( 8.4 )
8.1Pregnancy Risk Summary Following oral administration, concentrations of lubiprostone in plasma are below the level of quantitation; however, one of the metabolites, M3, has measurable systemic concentrations [see Clinical Pharmacology ( 12.3 )] . Limited available data with lubiprostone use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. Animal reproduction studies did not show an increase in structural malformations .
Although a dose dependent increase in fetal loss was observed in pregnant guinea pigs that received lubiprostone (doses equivalent to 0.2 to 6 times the maximum recommended human dose (MRHD) based on body surface area (mg/m 2 )), these effects were probably secondary to maternal toxicity and occurred after the period of organogenesis (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 estimated 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 developmental toxicity studies, pregnant rats and rabbits received oral lubiprostone during organogenesis at doses up to approximately 338 times (rats) and approximately 34 times (rabbits) the maximum recommended human dose (MRHD) based on body surface area (mg/m 2 ). Maximal animal doses were 2,000 mcg/kg/day (rats) and 100 mcg/kg/day (rabbits).
In rats, there were increased incidences of early resorptions and soft tissue malformations ( situs inversus , cleft palate) at the 2,000 mcg/kg/day dose; however, these effects were probably secondary to maternal toxicity. A dose-dependent increase in fetal loss occurred when guinea pigs received lubiprostone after the period of organogenesis, on days 40 to 53 of gestation, at daily oral doses of 1 mcg/kg/day, 10 mcg/kg/day, and 25 mcg/kg/day (approximately 0.2, 2 and 6 times the MRHD based on body surface area (mg/m 2 )); however, these effects were probably secondary to maternal toxicity.
The potential of lubiprostone to cause fetal loss was also examined in pregnant rhesus monkeys. Monkeys received lubiprostone post-organogenesis on gestation days 110 through 130 at daily oral doses of 10 mcg/kg/day and 30 mcg/kg/day (approximately 3 and 10 times the MRHD based on body surface area (mg/m 2 )). Fetal loss was noted in one monkey from the 10 mcg/kg dose group, which is within normal historical rates for this species.
There was no drug-related adverse effect seen in monkeys.
8.2Lactation Risk Summary There are no data available on the presence of lubiprostone in human milk or the effect of lubiprostone on milk production. There are limited data available on the effect of lubiprostone on the breastfed infant. Neither lubiprostone nor its active metabolite (M3) were present in the milk of lactating rats.
When a drug is not present in animal milk, it is likely that the drug will not be present in human milk. If present, lubiprostone may cause diarrhea in the breastfed infant (see Clinical Considerations) . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for lubiprostone and any potential adverse effects on the breastfed infant from lubiprostone or from the underlying maternal condition.
Clinical Considerations Infants of nursing mothers being treated with lubiprostone should be monitored for diarrhea.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness have not been established in pediatric patients with IBS-C, pediatric functional constipation (PFC), and OIC. Efficacy was not demonstrated for the treatment of PFC in patients 6 years of age and older in a 12 week, randomized, double-blind, placebo-controlled trial conducted in 606 patients 6 years to 17 years with PFC comparing lubiprostone to placebo. The primary efficacy endpoint was an overall response based on spontaneous bowel movement frequency over the duration of the trial; the treatment difference from placebo was not statistically significant.
In this age group, adverse reactions to lubiprostone were similar to those reported in adults. In a 36-week, long-term safety extension trial after approximately 9 months of treatment with lubiprostone, a single case of reversible elevation of ALT (17-times upper limit of normal [ULN]), AST (13-times ULN), and GGT (9-times [ULN]) was observed in a child with baseline elevated values (less than or equal to 2.5-times ULN). Juvenile Animal Toxicity Data In a 13-week oral toxicity study in juvenile rats, a significant decrease in total bone mineral density was observed in female pups at 0.5 mg/kg/day; in male pups, a significantly lower cortical thickness at the tibial diaphysis was observed at 0.5 mg/kg.
The 0.5 mg/kg/day dose is approximately 101 times the maximum recommended adult dose of 48 mcg/day, based on body surface area (mg/m 2 ).
🧓 Geriatric Use ▾
8.5Geriatric Use Chronic Idiopathic Constipation The efficacy of lubiprostone 24 mcg twice daily in the elderly (at least 65 years of age) subpopulation with CIC was consistent with the efficacy in the overall study population. Of the total number of patients treated in the dose-finding, efficacy, and long-term studies of lubiprostone, 16% were at least 65 years of age, and 4% were at least 75 years of age. Elderly patients taking lubiprostone experienced a lower rate of associated nausea compared to the overall study population taking lubiprostone (19% vs.
29%, respectively). Opioid-Induced Constipation The safety profile of lubiprostone in the elderly (at least 65 years of age) subpopulation with OIC (9% were at least 65 years of age and 2% were at least 75 years of age) was consistent with the safety profile in the overall study population. Clinical studies of lubiprostone did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients.
Irritable Bowel Syndrome with Constipation The safety profile of lubiprostone in the elderly (at least 65 years of age) subpopulation with IBS-C (8% were at least 65 years of age and 2% were at least 75 years of age) was consistent with the safety profile in the overall study population. Clinical studies of lubiprostone did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE There have been six reports of overdosage with lubiprostone during clinical development. Of these six cases, only two subjects reported adverse events: one reported vomiting, diarrhea and stomach ache after taking 168 to 192 mcg of lubiprostone, and another reported diarrhea and a joint injury on the day of overdose after taking 36 mcg of lubiprostone. Adverse reactions that occurred in at least 1% of healthy subjects given a single oral dose of 144 mcg of lubiprostone (6 times the highest recommended dose) in a cardiac repolarization study included nausea (45%), diarrhea (35%), vomiting (27%), dizziness (14%), headache (12%), abdominal pain (8%), flushing/hot flash (8%), retching (8%), dyspnea (4%), pallor (4%), stomach discomfort (4%), anorexia (2%), asthenia (2%), chest discomfort (2%), dry mouth (2%), hyperhidrosis (2%), and syncope (2%).

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Lubiprostone is a locally acting chloride channel activator that enhances a chloride-rich intestinal fluid secretion without altering sodium and potassium concentrations in the serum. Lubiprostone acts by specifically activating ClC-2, which is a normal constituent of the apical membrane of the human intestine, in a protein kinase A–independent fashion. By increasing intestinal fluid secretion, lubiprostone increases motility in the intestine, thereby facilitating the passage of stool and alleviating symptoms associated with chronic idiopathic constipation.
Patch clamp cell studies in human cell lines have indicated that the majority of the beneficial biological activity of lubiprostone and its metabolites is observed only on the apical (luminal) portion of the gastrointestinal epithelium. Lubiprostone, via activation of apical ClC-2 channels in intestinal epithelial cells, bypasses the antisecretory action of opiates that results from suppression of secretomotor neuron excitability. Activation of ClC-2 by lubiprostone has also been shown to stimulate recovery of mucosal barrier function and reduce intestinal permeability via the restoration of tight junction protein complexes in ex vivo studies of ischemic porcine intestine.
12.2Pharmacodynamics Although the pharmacologic effects of lubiprostone in humans have not been fully evaluated, animal studies have shown that oral administration of lubiprostone increases chloride ion transport into the intestinal lumen, enhances fluid secretion into the bowels, and improves fecal transit.
12.3Pharmacokinetics Following oral administration, concentrations of lubiprostone in plasma are below the level of quantitation (10 pg/mL). Therefore, standard pharmacokinetic parameters such as area under the curve (AUC), maximum concentration (C max ), and half-life (t ½ ) cannot be reliably calculated. However, the pharmacokinetic parameters of M3 (only measurable active metabolite of lubiprostone) have been characterized.
Absorption Peak plasma concentrations of M3, after a single oral dose of 24 mcg of lubiprostone, occurred at approximately 1.1 hours. The C max was 41.5 pg/mL and the mean AUC 0–t was 57.1 pg·hr/mL. The AUC 0–t of M3 increases dose proportionally after single 24 mcg and 144 mcg doses of lubiprostone (6-times the maximum recommended 24 mcg dose).
Food Effect A study was conducted with a single 72 mcg dose of 3 H-labeled lubiprostone (3-times the maximum recommended 24 mcg dose) to evaluate the potential of a food effect on lubiprostone absorption, metabolism, and excretion. Pharmacokinetic parameters of total radioactivity demonstrated that C max decreased by 55% while AUC 0–∞ was unchanged when lubiprostone was administered with a high-fat meal. The clinical relevance of the effect of food on the pharmacokinetics of lubiprostone is not clear.
However, lubiprostone was administered with food and water in a majority of clinical trials. Distribution In vitro protein binding studies indicate lubiprostone is approximately 94% bound to human plasma proteins. Elimination Metabolism Lubiprostone is rapidly and extensively metabolized by 15-position reduction, α-chain β-oxidation, and ω-chain ω-oxidation.
In vitro studies using human liver microsomes indicate that cytochrome P450 isoenzymes are not involved in the metabolism of lubiprostone. Further in vitro studies indicate that M3, a metabolite of lubiprostone, is formed by the reduction of the 15-carbonyl moiety to a hydroxy moiety by microsomal carbonyl reductase. M3 makes up less than 10% of the dose of radiolabeled lubiprostone.
Animal studies have shown that metabolism of lubiprostone rapidly occurs within the stomach and jejunum, most likely in the absence of any systemic absorption. Excretion Lubiprostone could not be detected in plasma; however, M3 has a t ½ ranging from 0.9 hours to 1.4 hours. After a single oral dose of 72 mcg of 3 H-labeled lubiprostone, 60% of total admini…
