What is Tiglutik Kit?
From the FDA label:Riluzole is a member of the benzothiazole class. The chemical designation for riluzole is 2-amino-6-(trifluoromethoxy)benzothiazole. Its molecular formula is C 8 H 5 F 3 N 2 OS, and its molecular weight is 234.2. The chemical structure is: Riluzole is a white to slightly yellow powder that is very soluble in dimethylformamide, dimethylsulfoxide, and methanol; freely soluble in dichloromethane; sparingly soluble in 0.1 N HCl; and very slightly soluble in water and in 0.1 N NaOH. TIGLUTIK (50 mg/10mL) oral suspension is a slightly brown, opaque, homogeneous suspension containing 50 mg of riluzole per 10 mL of suspension. TIGLUTIK also contains the following inactive ingredients: magnesium aluminum silicate, noncrystallizing sorbitol solution, polyoxyl 20 cetostearyl ether, purified water, saccharin sodium, simethicone emulsion, sodium lauryl sulfate, and xanthan gum.

How to use
Recommended dosage: 50 mg (10 mL), twice daily, taken orally or via percutaneous endoscopic gastrostomy tubes (PEG-tubes), every 12 hours ( 2.1 ) Measure serum aminotransferases before and during treatment ( 2.2 , 5.1 ) Take at least 1 hour before or 2 hours after a meal ( 2.3 ) 2.1 Dosage Information The recommended dosage for TIGLUTIK is 50 mg (10 mL) taken orally or via Percutaneous Endoscopic Gastrostomy tubes (PEG-tubes) twice daily, every 12 hours.

Side effects
The following adverse reactions are described below and elsewhere in the labeling: Hepatic Injury [see Warnings and Precautions (5.1) ] Neutropenia [see Warnings and Precautions (5.2) ] Interstitial Lung Disease [see Warnings and Precautions (5.3) ] Pancreatitis [see Warnings and Precautions (5.4)] Most common adverse reactions (incidence greater than or equal to 5% and greater than placebo) were oral hypoesthesia, asthenia, nausea, decreased lung function, hypertension, and abdominal pain ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact EDW Pharma, at 1-800-664-1490 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical 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. Adverse Reactions in Controlled Clinical Trials of Riluzole Tablets In the placebo-controlled clinical trials in patients with ALS (Study 1 and 2), a total of 313 patients received riluzole 50 mg twice daily [see Clinical Studies (14) ]. The most common adverse reactions in riluzole-treated patients (in at least 5% of patients and more frequently than on placebo) were asthenia, nausea, decreased lung function, hypertension, and abdominal pain. The most common adverse…
Warnings
Important safety information
Hepatic injury: Use of TIGLUTIK is not recommended in patients with baseline elevations of serum aminotransferases greater than 5 times the upper limit of normal; discontinue TIGLUTIK if there is evidence of liver dysfunction ( 5.1 ) Neutropenia: Advise patients to report any febrile illness ( 5.2 ) Interstitial lung disease: Discontinue TIGLUTIK if interstitial lung disease develops ( 5.3 ) Pancreatitis: There have been postmarketing reports of acute pancreatitis.If pancreatitis is suspected, promptly discontinue TIGLUTIK (5.4) 5.1 Hepatic Injury TIGLUTIK can cause liver injury. Cases of drug-induced liver injury, some of which were fatal, have been reported in patients taking riluzole. Asymptomatic elevations of hepatic transaminases have also been reported, and in some patients have recurred upon re-challenge with riluzole. In clinical studies, the incidence of elevations in hepatic transaminases was greater in riluzole-treated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2% in riluzole-treated patients. Maximum increases in ALT occurred within 3 months after starting riluzole. About 50% and 8% of riluzole-treated patients in pooled controlled efficacy studies (Studies 1 and 2) had at least one elevated ALT level above ULN and above 3 times ULN, respectively [see Clinical Studies (14) ]. Monitor patients for signs and symptoms of hepatic injury, every month for the first 3 months of treatment, and periodically thereafter. The use of TIGLUTIK is not recommended if patients develop hepatic transaminases levels greater than 5 times the ULN. Discontinue TIGLUTIK if there is evidence of liver dysfunction (e.g., elevated bilirubin). Concomitant use with other hepatotoxic drugs may increase the risk for hepatotoxicity [see Drug Interactions (7.3) ] . 5.2 Neutropenia TIGLUTIK can cause neutropenia. Cases of severe neutropenia (absolute neutrophil count less than 500 per mm 3 ) within the first 2 months of riluzole treatment have been reported. Advise patients to report febrile illnesses. 5.3 Interstitial Lung Disease TIGLUTIK can cause interstitial lung disease, including hypersensitivity pneumonitis. Discontinue TIGLUTIK immediately if interstitial lung disease develops. 5.4 Pancreatitis Acute pancreatitis, including fatal and non-fatal necrotizing pancreatitis, has been observed in patients treated with riluzole in the postmarketing setting. Pancreatitis has occurred weeks to several years after initiation of riluzole. Patients and caregivers should be warned that abdominal pain, nausea, vomiting, and/or anorexia can be symptoms of pancreatitis that require prompt medical evaluation. If pancreatitis is suspected promptly discontinue TIGLUTIK and initiate appropriate management. If an alternative cause is identified, reinitiation of TIGLUTIK may be considered.
Who should not take Tiglutik Kit
TIGLUTIK is contraindicated in patients with a history of severe hypersensitivity reactions to riluzole or to any of its components (anaphylaxis has occurred) [see Adverse Reactions (6.1) ]. Patients with a history of severe hypersensitivity reactions to riluzole or to any of its components ( 4 )
Overdose — what happens if you take too much
Reported symptoms of overdose following ingestion of riluzole ranging from 1.5 to 3 grams (30 to 60 times the recommended dose) included acute toxic encephalopathy, coma, drowsiness, memory loss, and methemoglobinemia. No specific antidote for the treatment of TIGLUTIK overdose is available. For current information on the management of poisoning or overdosage, contact a certified poison control center.

Interactions
Strong to moderate CYP1A2 inhibitors: Co-administration may increase TIGLUTIK-associated adverse reactions ( 7.1 ) Strong to moderate CYP1A2 inducers: Co-administration may result in decreased efficacy ( 7.2 ) Hepatotoxic drugs: TIGLUTIK-treated patients that take other hepatotoxic drugs may be at increased risk for hepatotoxicity ( 7.3 ) 7.1 Agents that may Increase Riluzole Blood Concentrations CYP1A2 Inhibitors Co-administration of riluzole (a CYP1A substrate) with CYP1A2 inhibitors was not evaluated in a clinical trial; however, in vitro findings suggest an increase in riluzole exposure is likely. The concomitant use of strong or moderate CYP1A2 inhibitors (e.g., ciprofloxacin, enoxacin, fluvoxamine, methoxsalen, mexiletine, oral contraceptives, thiabendazole, vemurafenib, zileuton) with TIGLUTIK may increase the risk of TIGLUTIK - associated adverse reactions [see Clinical Pharmacology (12.3) ]. 7.2 Agents that may Decrease Riluzole Plasma Concentrations CYP1A2 Inducers Co-administration of riluzole (a CYP1A substrate) with CYP1A2 inducers was not evaluated in a clinical trial; however, in vitro findings suggest a decrease in riluzole exposure is likely. Lower exposures may result in decreased efficacy [see Clinical Pharmacology (12.3) ] . 7.3 Hepatotoxic Drugs Clinical trials in ALS patients excluded patients on concomitant medications which were potentially hepatotoxic (e.g., allopurinol, methyldopa, sulfasalazine). TIGLUTIK-treated patients who take other hepatotoxic drugs may be at an increased risk for hepatotoxicity [see Warnings and Precautions (5.1) ].
