Warnings and precautions

Renal Impairment: Assess renal function at the beginning of treatment and periodically during treatment. Evaluate the risks and benefits in patients with known renal impairment or taking nephrotoxic drugs; monitor renal function. Discontinue if renal function deteriorates. ( 5.1 , 7.2 , 8.6 ) Mesalamine-Induced Acute Intolerance Syndrome: Symptoms may be difficult to distinguish from an exacerbation of ulcerative colitis; monitor for worsening symptoms; discontinue treatment if acute intolerance syndrome is suspected. (5.2 ) Hypersensitivity Reactions, including Myocarditis and Pericarditis: Evaluate patients immediately and discontinue if a hypersensitivity reaction is suspected. ( 5.3 ) Hepatic Failure: Evaluate the risks and benefits in patients with known liver impairment. ( 5.4 ) Severe Cutaneous Adverse Reactions: Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. ( 5.5 ) Photosensitivity : Advise patients with pre-existing skin conditions to avoid sun exposure, wear protective clothing, and use a broad-spectrum sunscreen when outdoors. ( 5.6 ) Nephrolithiasis: Mesalamine-containing stones are undetectable by standard radiography or computed tomography (CT). Ensure adequate fluid intake during treatment. ( 5.7 ) Risks in Patients with Phenylketonuria : Contains phenylalanine. Before prescribing APRISO to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including APRISO. ( 5.8 ) Interference with Laboratory Tests : Use of mesalamine may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection. ( 5.9 ) 5.1 Renal Impairment Renal impairment, including minimal change disease, acute and chronic interstitial nephritis, and renal failure, has been reported in patients given products such as APRISO that contain mesalamine or are converted to mesalamine. In animal studies, the kidney was the principal organ of mesalamine toxicity [see Adverse Reactions ( 6.2 ), Nonclinical Toxicology ( 13.2 )]. Evaluate renal function prior to initiation of APRISO therapy and periodically while on therapy. Evaluate the risks and benefits of using APRISO in patients with known renal impairment or a history of renal disease or taking concomitant nephrotoxic drugs. Discontinue APRISO if renal function deteriorates while on therapy [see Drug Interactions ( 7.2 ), Use in Specific Populations ( 8.6 )] . 5.2 Mesalamine-Induced Acute Intolerance Syndrome Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from an exacerbation of ulcerative colitis. Although the exact frequency of occurrence has not been determined, it has occurred in 3% of patients in controlled clinical trials of mesalamine or sulfasalazine. Symptoms include cramping, acute abdominal pain and bloody diarrhea, sometimes fever, headache, and rash. Monitor patients for worsening of these symptoms while on treatment. If acute intolerance syndrome is suspected, promptly discontinue treatment with APRISO. 5.3 Hypersensitivity Reactions Some patients have experienced a hypersensitivity reaction to sulfasalazine. Some patients may have a similar reaction to APRISO or to other compounds that contain or are converted to mesalamine. As with sulfasalazine, mesalamine-induced hypersensitivity reactions may present as internal organ involvement, including myocarditis, pericarditis, nephritis, hepatitis, pneumonitis and hematologic abnormalities. Evaluate patients immediately if signs or symptoms of a hypersensitivity reaction are present. Discontinue APRISO if an alternative etiology for the signs and symptoms cannot be established. 5.4 Hepatic Failure There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Evaluate the risks and benefits of using APRISO in patients with known liver impairment. 5.5 Severe Cutaneous Adverse Reactions Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) have been reported with the use of mesalamine [see Adverse Reactions (6.2) ] . Discontinue APRISO at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. 5.6 Photosensitivity Patients with pre-existing skin conditions such as atopic dermatitis and atopic eczema have reported more severe photosensitivity reactions. Advise patients to avoid sun exposure, wear protective clothing, and use a broad-spectrum sunscreen when outdoors. 5.7 Nephrolithiasis Cases of nephrolithiasis have been reported with the use of mesalamine, including stones with 100% mesalamine content. Mesalamine-containing stones are radiotransparent and undetectable by standard radiography or computed tomography (CT). Ensure adequate fluid intake during treatment with APRISO. 5.8 Risks in Patients with Phenylketonuria Phenylalanine can be harmful to patients with phenylketonuria (PKU). APRISO contains phenylalanine, a component of aspartame. Each APRISO 0.375 g capsule contains 0.56 mg of phenylalanine. Before prescribing APRISO to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including APRISO. 5.9 Interference with Laboratory Tests Use of APRISO may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection because of the similarity in the chromatograms of normetanephrine and the main metabolite of mesalamine, N-acetyl-5-aminosalicylic acid (N-Ac-5-ASA). Consider an alternative, selective assay for normetanephrine.

Side effects

The following clinically significant adverse reactions are described elsewhere in labeling: Renal Impairment [see Warnings and Precautions ( 5.1 )] Mesalamine-Induced Acute Intolerance Syndrome [see Warnings and Precautions ( 5.2 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.3 )] Hepatic Failure [see Warnings and Precautions ( 5.4 )] Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.5) ] Photosensitivity [see Warnings and Precautions ( 5.6 )] Nephrolithiasis [see Warnings and Precautions ( 5.7 )] Risks in Patients with Phenylketonuria [see Warnings and Precautions ( 5.8 )] Most common adverse reactions (≥3%) are: headache, diarrhea, upper abdominal pain, nausea, and nasopharyngitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Salix Pharmaceuticals at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies 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 data described below reflect exposure to APRISO in 557 patients, including 354 exposed for at least 6 months and 250 exposed for greater than one year. APRISO was studied in two placebo-controlled trials (n=367 treated with APRISO) and in one open-label, long-term study (n=190 additional patients). The population consisted of patients with ulcerative colitis; the mean age was 47 years, 54% were female, and 93% were white. Patients received doses of APRISO 1.5 g administered orally once per day for six months in the placebo-controlled trials and for up to 24 months in the open‑label study. In the two placebo-controlled trials, the most common reactions reported in at least 3% of APRISO-treated patients and at a greater rate than placebo are shown in Table 1 below. Table 1: Common Adverse Reactions Reported in at least 3% of APRISO-treated patients and at a greater rate than with placebo in Clinical Trials of Adults with Ulcerative Colitis APRISO 1.5 g once daily N=367 Placebo N=185 Headache 11% 8% Diarrhea 8% 7% Upper Abdominal Pain 5% 3% Nausea 4% 3% Nasopharyngitis 4% 3% The following adverse reactions, presented by body system, were reported at a frequency less than 3% in patients treated with APRISO for up to 24 months in controlled and open-label trials. Ear and Labyrinth Disorders : tinnitus, vertigo Dermatological Disorder : alopecia Gastrointestinal : lower abdominal pain, rectal hemorrhage Laboratory Abnormalities : increased triglycerides, decreased hematocrit and hemoglobin General Disorders and Administration Site Disorders : fatigue Hepatic : hepatitis cholestatic, transaminases increased Renal Disorders : creatinine clearance decreased, hematuria Musculoskeletal : pain, arthralgia Respiratory : dyspnea 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of APRISO or other mesalamine-containing products. Because many of these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Body as a Whole : lupus-like syndrome, drug fever Cardiovascular : pericarditis, pericardial effusion, myocarditis [see Warnings and Precautions ( 5.3 )] Gastrointestinal : pancreatitis, cholecystitis, gastritis, gastroenteritis, gastrointestinal bleeding, perforated peptic ulcer Hepatic : jaundice, cholestatic jaundice, hepatitis, liver necrosis, liver failure, Kawasaki-like syndrome including changes in liver enzymes Hematologic : agranulocytosis, aplastic anemia Nervous System : intracranial hypertension Neurological/Psychiatric : peripheral neuropathy, Guillain-Barré syndrome, transverse myelitis Renal and Urinary : nephrogenic diabetes insipidus, interstitial nephritis, renal failure, minimal change disease, nephrolithiasis [see Warnings and Precautions ( 5.1 , 5.7 )] Urine discoloration occurring ex-vivo caused by contact of mesalamine, including inactive metabolite, with surfaces or water treated with hypochlorite-containing bleach. Respiratory/Pulmonary : eosinophilic pneumonia, interstitial pneumonitis, pleurisy/pleuritis Skin : psoriasis, pyoderma gangrenosum, erythema nodosum, SJS/TEN, DRESS, and AGEP [ see Warnings and Precautions (5.5) ] Renal/Urogenital : reversible oligospermia

Drug interactions

Nephrotoxic Agents including NSAIDs: Increased risk of nephrotoxicity; monitor for changes in renal function and mesalamine-related adverse reactions. ( 7.2 ) Azathioprine or 6-Mercaptopurine: Increased risk of blood disorders; monitor complete blood cell counts and platelet counts. ( 7.3 ) 7.1 Antacids Because the dissolution of the coating of the granules in APRISO capsules depends on pH, avoid co-administration of APRISO capsules with antacids [see Dosage and Administration (2) ] . 7.2 Nephrotoxic Agents, Including Non-Steroidal Anti-Inflammatory Drugs The concurrent use of mesalamine with known nephrotoxic agents, including non-steroidal anti-inflammatory drugs (NSAIDs) may increase the risk of nephrotoxicity. Monitor patients taking nephrotoxic drugs for changes in renal function and mesalamine-related adverse reactions [see Warnings and Precautions ( 5.1 )]. 7.3 Azathioprine or 6-Mercaptopurine The concurrent use of mesalamine with azathioprine or 6-mercaptopurine and/or other drugs known to cause myelotoxicity may increase the risk for blood disorders, bone marrow failure, and associated complications. If concomitant use of APRISO and azathioprine or 6-mercaptopurine cannot be avoided, monitor blood tests, including complete blood cell counts and platelet counts. 7.4 Interference with Urinary Normetanephrine Measurements Use of APRISO may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection [see Warnings and Precautions ( 5.9 )] . Consider an alternative, selective assay for normetanephrine.

Use in specific populations

Geriatric Patients : Increased risk of blood dyscrasias; monitor blood cell counts and platelet counts. ( 8.5 ) 8.1 Pregnancy Risk Summary Published data from meta-analyses, cohort studies and case series on the use of mesalamine during pregnancy have not reliably informed an association with mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes ( see Data ) . In animal reproduction studies, there were no adverse developmental outcomes with administration of oral mesalamine during organogenesis to pregnant rats and rabbits at doses 1.7 and 5.4 times, respectively, the maximum recommended human dose ( see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. 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. Clinical Considerations Disease-associated maternal and embryo/fetal risk Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with ulcerative colitis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Data Human Data Published data from meta-analyses, cohort studies and case series on the use of mesalamine during early pregnancy (first trimester) and throughout pregnancy have not reliably informed an association of mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes. There is no clear evidence that mesalamine exposure in early pregnancy is associated with an increased risk in major congenital malformations, including cardiac malformations. Published epidemiologic studies have important methodological limitations which hinder interpretation of the data, including inability to control for confounders, such as underlying maternal disease, and maternal use of concomitant medications, and missing information on the dose and duration of use for mesalamine products. Animal Data Reproduction studies with mesalamine during organogenesis have been performed in rats at oral doses up to 320 mg/kg/day (about 1.7 times the recommended human dose based on a body surface area comparison) and rabbits at doses up to 495 mg/kg/day (about 5.4 times the recommended human dose based on a body surface area comparison) and have revealed no evidence of harm to the fetus due to mesalamine. 8.2 Lactation Risk Summary Data from published literature report the presence of mesalamine and its metabolite, N-acetyl 5-aminosalicylic acid in human milk in small amounts with relative infant doses (RID) of 2% or less ( see Data ) . There are case reports of diarrhea in breastfed infants exposed to mesalamine (see Clinical Considerations) . There is no information on the effects of the drug on milk production. The lack of clinical data during lactation precludes a clear determination of the risk of APRISO to an infant during lactation; therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for APRISO and any potential adverse effects on the breastfed child from APRISO or from the underlying maternal condition. Clinical Considerations Advise the caregiver to monitor the breastfed infant for diarrhea. Data In published lactation studies, maternal mesalamine doses from various oral and rectal formulations and products ranged from 500 mg to 4.8 g daily. The average concentration of mesalamine in milk ranged from non-detectable to 0.5 mg/L. The average concentration of the N-acetyl-5-aminosalicylic acid in milk ranged from 0.2 to 9.3 mg/L. Based on these concentrations, estimated infant daily dosages for an exclusively breastfed infant are 0 to 0.075 mg/kg/day (RID 0 to 0.1%) of mesalamine and 0.03 to 1.4 mg/kg/day of N-acetyl-5-aminosalicylic acid. 8.4 Pediatric Use Safety and effectiveness of APRISO in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of APRISO did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently than younger subjects. Reports from uncontrolled clinical studies and postmarketing reporting systems suggested a higher incidence of blood dyscrasias (i.e., agranulocytosis, neutropenia and pancytopenia) in patients who were 65 years or older compared to younger patients taking mesalamine-containing products such as APRISO. Monitor complete blood cell counts and platelet counts in elderly patients during treatment with APRISO. In general, consider the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy in elderly patients when prescribing APRISO [see Use in Specific Populations ( 8.6 )]. 8.6 Renal Impairment Mesalamine is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Evaluate renal function in all patients prior to initiation and periodically while on APRISO therapy. Monitor patients with known renal impairment or history of renal disease or taking nephrotoxic drugs for decreased renal function and mesalamine-related adverse reactions. Discontinue APRISO if renal function deteriorates while on therapy [see Warnings and Precautions (5.1) , Adverse Reactions (6.2) , Drug Interactions (7.2)].

Pediatric use

8.4 Pediatric Use Safety and effectiveness of APRISO in pediatric patients have not been established.

Geriatric use

8.5 Geriatric Use Clinical studies of APRISO did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently than younger subjects. Reports from uncontrolled clinical studies and postmarketing reporting systems suggested a higher incidence of blood dyscrasias (i.e., agranulocytosis, neutropenia and pancytopenia) in patients who were 65 years or older compared to younger patients taking mesalamine-containing products such as APRISO. Monitor complete blood cell counts and platelet counts in elderly patients during treatment with APRISO. In general, consider the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy in elderly patients when prescribing APRISO [see Use in Specific Populations ( 8.6 )].

Overdosage

10 OVERDOSAGE APRISO is an aminosalicylate, and symptoms of salicylate toxicity include nausea, vomiting and abdominal pain, tachypnea, hyperpnea, tinnitus, and neurologic symptoms (headache, dizziness, confusion, seizures). Severe salicylate intoxication may lead to electrolyte and blood pH imbalance and potentially to other organ (e.g., renal and liver) damage. There is no specific antidote for mesalamine overdose; however, conventional therapy for salicylate toxicity may be beneficial in the event of acute overdosage and may include gastrointestinal tract decontamination to prevent further absorption. Correct fluid and electrolyte imbalance by the administration of appropriate intravenous therapy and maintain adequate renal function. APRISO is a pH-dependent delayed-release product and this factor should be considered when treating a suspected overdose.

Description

Each APRISO ® capsule is a delayed- and extended-release dosage form for oral administration. Each capsule contains 0.375 g of mesalamine USP (5-aminosalicylic acid, 5-ASA), an aminosalicylate. The structural formula of mesalamine is: Molecular Weight: 153.14 Molecular Formula: C 7 H 7 NO 3 Each APRISO capsule contains granules composed of mesalamine in a polymer matrix with an enteric coating that dissolves at pH 6 and above. The inactive ingredients of APRISO capsules are: anhydrous citric acid, aspartame, colloidal silicon dioxide, edible black ink, hypromellose, magnesium stearate, methacrylic acid copolymer, microcrystalline cellulose, povidone, simethicone emulsion, ethyl acrylate/methyl methacrylate copolymer, talc, titanium dioxide, triethyl citrate, vanilla flavor. Each APRISO 0.375 g capsule contains 0.56 mg of phenylalanine. Chemical Structure

Mechanism of action

12.1 Mechanism of Action The mechanism of action of mesalamine (5-ASA) is not fully understood, but appears to be a local anti-inflammatory effect on colonic epithelial cells. Mucosal production of arachidonic acid metabolites, both through the cyclooxygenase pathways, i.e., prostanoids, and through the lipoxygenase pathways, i.e., leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with ulcerative colitis, and it is possible that 5-ASA diminishes inflammation by blocking production of arachidonic acid metabolites.

Patient information

Administration Instruct patients: Swallow the capsules whole. Do not cut, break, crush or chew the capsules. Avoid co-administration of APRISO with antacids. Drink an adequate amount of fluids. APRISO capsules can be taken without regard to meals [ see Dosage and Administration (2) ] . Urine may become discolored reddish-brown while taking APRISO when it comes in contact with surfaces or water treated with hypochlorite-containing bleach. If discolored urine is observed, advise patients to observe their urine flow. Report to the healthcare provider only if urine is discolored on leaving the body, before contact with any surface or water (e.g., in the toilet). Renal Impairment Inform patients that APRISO may decrease their renal function, especially if they have known renal impairment or are taking nephrotoxic drugs, including NSAIDs, and periodic monitoring of renal function will be performed while they are on therapy. Advise patients to complete all blood tests ordered by their healthcare provider [ see Warnings and Precautions (5.1) , Drug Interactions (7.2) ] . Mesalamine-Induced Acute Intolerance Syndrome and Other Hypersensitivity Reactions Inform patients of the signs and symptoms of hypersensitivity reactions. Instruct patients to stop taking APRISO and report to their healthcare provider if they experience new or worsening symptoms of Acute Intolerance Syndrome (cramping, abdominal pain, bloody diarrhea, fever, headache, and rash) or other symptoms suggestive of mesalamine-induced hypersensitivity [ see Warnings and Precautions (5.2, 5.3) ] .
