Tolectin

INDICATIONS & USAGE Carefully consider the potential benefits and risks of TOLECTIN tablets, USP and other treatment options before deciding to use TOLECTIN tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS ). TOLECTIN tablets are indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. TOLECTIN tablets are indicated in the treatment of acute flares and the long-term management of the chronic disease. TOLECTIN tablets are also indicated for treatment of juvenile rheumatoid arthritis. The safety and effectiveness of TOLECTIN tablets have not been established in pediatric patients under 2 years of age (see PRECAUTIONS : Pediatric Use and DOSAGE AND ADMINISTRATION ).

DOSAGE & ADMINISTRATION Carefully consider the potential benefits and risks of TOLECTIN and other treatment options before deciding to use TOLECTIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS ). After observing the response to initial therapy with TOLECTIN, the dose and frequency should be adjusted to suit an individual patient’s needs. For the relief of rheumatoid arthritis or osteoarthritis, the recommended starting dose for adults is 400 mg three times daily (1200 mg daily), preferably including a dose on arising and a dose at bedtime. To achieve optimal therapeutic effect the dose should be adjusted according to the patient’s response after 1 or 2 weeks. Control is usually achieved at doses of 600 mg to 1800 mg daily in divided doses (generally t.i.d.). Doses larger than 1800 mg/day have not been studied and are not recommended. For the relief of juvenile rheumatoid arthritis, the recommended starting dose for pediatric patients (2 years and older) is 20 mg/kg/day in divided doses (t.i.d. or q.i.d.). When control has been achieved, the usual dose ranges from 15 to 30 mg/kg/day. Doses higher than 30 mg/kg/day have not been studied, and, therefore, are not recommended. A therapeutic response to TOLECTIN can be expected in a few days to a week. Progressive improvement can be anticipated during succeeding weeks of therapy. If gastrointestinal symptoms occur, TOLECTIN can be administered with antacids other than sodium bicarbonate. TOLECTIN bioavailability and pharmacokinetics are not significantly affected by acute or chronic administration of magnesium and aluminum hydroxides; however, bioavailability is affected by food or milk (see PRECAUTIONS: Drug-Food Interaction ).

WARNINGS Cardiovascular Effects Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to 3 years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as tolmetin, increases the risk of serious gastrointestinal (GI) events (see WARNINGS ). Status Post Coronary Artery Bypass Graft (CABG) Surgery: Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. NSAIDs are contraindicated in the setting of CABG (see CONTRAINDICATIONS ). Post-MI Patients: Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first year post MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next 4 years of follow-up. Avoid the use of TOLECTIN in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If TOLECTIN is used in patients with a recent MI, monitor patients for signs of cardiac ischemia. Hypertension: NSAIDs, including TOLECTIN, can lead to onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including TOLECTIN, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Heart Failure and Edema: The Coxib and traditional NSAID Trialists’ Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death. Additionally, fluid retention and edema have been observed in …

CONTRAINDICATIONS TOLECTIN tablets are contraindicated in patients with known hypersensitivity to tolmetin sodium. TOLECTIN should not be given to patients who have experienced asthma, urticaria or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactoid Reactions and PRECAUTIONS: General : Preexisting Asthma ). TOLECTIN is contraindicated in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS ).

DRUG INTERACTIONS ACE Inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE Inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE Inhibitors. Aspirin: As with other NSAIDs, concomitant administration of TOLECTIN sodium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics: Clinical studies, as well as post-marketing observations have shown that NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy. Lithium: NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate: NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin: The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. The in vitro binding of warfarin to human plasma proteins is unaffected by TOLECTIN, and TOLECTIN does not alter the prothrombin time of normal volunteers. However, increased prothrombin time and bleeding have been reported in patients on concomitant tolmetin and warfarin therapy. Therefore, caution should be exercised when administering tolmetin to patients on anticoagulants. Hypoglycemic Agents: In adult diabetic patients under treatment with either sulfonylureas or insulin there is no change in the clinical effects of either TOLECTIN or the hypoglycemic agents.

PREGNANCY Risk Summary: Use of NSAIDs, including TOLECTIN, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of TOLECTIN use between about 20 and 30 weeks of gestation, and avoid TOLECTIN use at about 30 weeks of gestation and later in pregnancy (see WARNINGS: Fetal Toxicity ). Premature Closure of Fetal Ductus Arteriosus: Use of NSAIDs, including TOLECTIN, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment: Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In animal reproduction studies in rats and rabbits at doses up to 50 mg/kg (1.5 times the maximum clinical dose based on a body weight of 60 kg) there revealed no evidence of teratogenesis or impaired fertility due to tolmetin. However, animal reproduction studies are not always predictive of human response. Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as tolmetin, resulted in increased pre- and post-implantation loss. Prostaglandins also have been shown to have an important role in fetal kidney development. In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. The estimated background risk of major birth defects and miscarriage for the indicated population(s) 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. Clinical Considerations: Fetal/Neonatal Adverse Reactions: Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including TOLECTIN, can cause premature closure of the fetal ductus arteriosus (see WARNINGS: Fetal Toxicity ). Oligohydramnios/Neonatal Renal Impairment: If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. If TOLECTIN treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue tolmetin sodium tablets and follow up according to clinical practice (see WARNINGS: Fetal Toxicity ). Data: Human Data: There are no adequate, well controlled studies in pregnant women. TOLECTIN should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Premature Closure of Fetal Ductus Arteriosus: Published literature reports that the use of NSAIDs at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment: Published studies and postmarketing reports describe maternal NSAID use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. In many cases, but not all, the decrease in amniotic fluid was transient and reversible wit…

NURSING MOTHERS Tolmetin sodium has been shown to be secreted in human milk. Because of the potential for serious adverse reactions in nursing infants from tolmetin sodium, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

ADVERSE REACTIONS The adverse reactions which have been observed in clinical trials encompass observations in about 4,370 patients treated with TOLECTIN, over 800 of whom have undergone at least one year of therapy. These adverse reactions, reported below by body system, are among those typical of nonsteroidal anti-inflammatory drugs and, as expected, gastrointestinal complaints were most frequent. In clinical trials with tolmetin, about 10% of patients dropped out because of adverse reactions, mostly gastrointestinal in nature. Incidence Greater Than 1%: The following adverse reactions which occurred more frequently than 1 in 100 were reported in controlled clinical trials: Gastrointestinal: nausea (11%), dyspepsia*, gastrointestinal distress*, abdominal pain*, diarrhea*, flatulence*, vomiting*, constipation, gastritis, and peptic ulcer. Forty percent of the ulcer patients had a prior history of peptic ulcer disease and/or were receiving concomitant anti-inflammatory drugs including corticosteroids, which are known to produce peptic ulceration. Body as a Whole: headache*, asthenia*, chest pain Cardiovascular: elevated blood pressure*, edema* Central Nervous System: dizziness*, drowsiness, depression Metabolic/Nutritional: weight gain*, weight loss* Dermatologic: skin irritation Special Senses: tinnitus, visual disturbance Hematologic: Small and transient decreases in hemoglobin and hematocrit not associated with gastrointestinal bleeding have occurred. These are similar to changes reported with other nonsteroidal anti-inflammatory drugs. Urogenital: elevated BUN, urinary tract infection *Reactions occurring in 3% to 9% of patients treated with TOLECTIN. Reactions occurring in fewer than 3% of the patients are unmarked. Incidence Less Than 1%: (Causal Relationship Probable) The following adverse reactions were reported less frequently than 1 in 100 in controlled clinical trials or were reported since marketing. The probability exists that there is a causal relationship between TOLECTIN and these adverse reactions. Gastrointestinal: gastrointestinal bleeding with or without evidence of peptic ulcer, perforation, glossitis, stomatitis, hepatitis, liver function abnormalities Body as a Whole: anaphylactoid reactions, fever, lymphadenopathy, serum sickness Hematologic: hemolytic anemia, thrombocytopenia, granulocytopenia, agranulocytosis Cardiovascular: congestive heart failure in patients with marginal cardiac function Dermatologic: urticaria, purpura, erythema multiforme, toxic epidermal necrolysis Urogenital: hematuria, proteinuria, dysuria, renal failure Incidence Less Than 1%: (Causal Relationship Unknown) Other adverse reactions were reported less frequently than 1 in 100 in controlled clinical trials or were reported since marketing, but a causal relationship between tolmetin and the reaction could not be determined. These rarely reported reactions are being listed as alerting information for the physician since the possibility of a causal relationship cannot be excluded.
