The dosage regimen should be adjusted based on patient response and tolerance to Etodolac (Etova-MR). The lowest effective dose should be used for maintenance therapy.

Precautions

NSAIDs may cause an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of administration. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with NSAIDs, the lowest effective dose should be used for the shortest duration possible. Prescribers and patients should remain vigilant for the development of such events, even in the absence of previous CV symptoms. Patients should be advised about the signs and/or 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.

NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. It has been shown that the incidence of upper GI ulcers, gross bleeding, or perforation, caused by NSAIDs, increases with duration of use. However, even short-term therapy is not without risk. Patients should be informed about the signs and symptoms of serious GI toxicities and the steps to take if they occur. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or GI bleeding. Patients with a prior history of peptic ulcer disease, and/or GI bleeding, and who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Since elderly patients are at greater risk for serious GI events, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high-risk patients, alternate therapies that do not involve NSAIDs should be considered. NSAIDs should be administered with care to patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn's disease) as their condition may be exacerbated.

Etodolac (Etova-MR) is contraindicated for the treatment of perioperative pain in patients undergoing coronary artery bypass graft (CABG) surgery. Patients with a hypersensitivity (angioedema, bronchospasm, urticaria, or rhinitis) to aspirin or other NSAIDs may be cross sensitive to Etodolac (Etova-MR). Patients with the "triad" of asthma, nasal polyps, and aspirin or other NSAID hypersensitivity are at particular risk. Fatal reactions have been reported in such patients. The use of Etodolac (Etova-MR) is considered contraindicated in these patients.

NSAIDs, including Etodolac (Etova-MR), can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to an increased incidence of CV events. NSAIDs, including Etodolac (Etova-MR), should be used with caution in patients with hypertension. Blood pressure should be monitored closely during the initiation of NSAID therapy and throughout the course of therapy.

Fluid retention and edema have been observed in some patients taking NSAIDs, including Etodolac (Etova-MR). Caution should be used when using Etodolac (Etova-MR) in patients with fluid retention, hypertension, or heart failure.

Long-term NSAIDs use has resulted in renal papillary necrosis and other renal injury. No information is available from controlled clinical trials regarding the use of Etodolac (Etova-MR) in patients with advanced renal disease. Therefore, treatment with Etodolac (Etova-MR) is not recommended in patients with advanced renal disease. Renal function may be further compromised by the use of Etodolac (Etova-MR) in patients with renal dysfunction, heart failure, hypovolemia, cirrhosis, nephrotic syndrome, or hypoalbuminemia. Renal blood flow in patients with renal dysfunction, edematous disorders, or hypovolemic states is dependent upon renal prostaglandin synthesis. If Etodolac (Etova-MR) must be used, periodic monitoring of renal function is recommended. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Caution is advised in patients with pre-existing kidney disease.

Patients who present with considerable dehydration should be rehydrated before starting therapy with Etodolac (Etova-MR).

NSAIDs, including Etodolac (Etova-MR), can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.

Etodolac (Etova-MR) should not be used as a substitute for corticosteroids or to treat corticosteroid insufficiency.

Borderline elevations of one or more liver tests have been reported in patients treated with Etodolac (Etova-MR). Elevations in ALT or AST (approximately three or more times the upper limit of normal) have been reported in clinical trials. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis, and hepatic failure, some of them with fatal outcomes, have been reported. Etodolac (Etova-MR) should be discontinued if clinical signs and symptoms consistent with liver disease develop or if systemic manifestations occur (e.g., eosinophilia, rash, etc.).

Anemia has been reported in patients receiving NSAIDs, including Etodolac (Etova-MR). This may due to fluid retention, GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including Etodolac (Etova-MR), should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia.

NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Patients receiving Etodolac (Etova-MR) who are also receiving anticoagulants or those who have coagulation disorders should be carefully monitored.

Patients receiving NSAIDs for long-term treatment should have their CBC and chemistry profile checked periodically.

Dialysis

Etodolac (Etova-MR) is not dialyzable.

Other Comments

If no improvement is seen within 2 to 4 weeks of therapy, an alternative NSAID should be considered.

Etodolac (Etova-MR) interactions

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.

Antacids

The concomitant administration of antacids has no apparent effect on the extent of absorption of Etodolac (Etova-MR). However, antacids can decrease the peak concentration reached by 15% to 20% but have no detectable effect on the time-to-peak.

Aspirin

When Etodolac (Etova-MR) is administered with aspirin, its protein binding is reduced, although the clearance of free Etodolac (Etova-MR) is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of Etodolac (Etova-MR) and aspirin is not generally recommended because of the potential of increased adverse effects.

Cyclosporine, Digoxin, Methotrexate

Etodolac (Etova-MR), like other NSAIDs, through effects on renal prostaglandins, may cause changes in the elimination of these drugs leading to elevated serum levels of cyclosporine, digoxin, methotrexate, and increase toxicity. Nephrotoxicity associated with cyclosporine may also be enhanced. Patients receiving these drugs who are given Etodolac (Etova-MR), or any other NSAID, and particularly those patients with altered renal function, should be observed for the development of the specific toxicities of these drugs. 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.

Diuretics

Etodolac (Etova-MR) has no apparent pharmacokinetic interaction when administered with furosemide or hydrochlorothiazide. Nevertheless, clinical studies, as well as post marketing observations have shown that Etodolac (Etova-MR) 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 sings of renal failure, as well as to assure diuretic efficacy.

Glyburide

Etodolac (Etova-MR) has no apparent pharmacokinetic interaction when administered with glyburide.

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.

Phenylbutazone

Phenylbutazone causes increase (by about 80%) in the free fraction of Etodolac (Etova-MR). Although in vivo studies have not been done to see if Etodolac (Etova-MR) clearance is changed by coadministration of phylbutazone, it is not recommended that they be coadministered.

Phenytoin

Etodolac (Etova-MR) has no apparent pharmacokinetic interaction when administered with phenytoin.

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 that of users of either drug alone. Short-term pharmacokinetic studies have demonstrated that concomitant administration of warfarin and Etodolac (Etova-MR) results in reduced protein binding of warfarin, but there was no change in the clearance of free warfarin. There was no significant difference in the pharmacodynamic effect of warfarin administered alone and warfarin administered with Etodolac (Etova-MR) as measured by prothrombin time. Thus, concomitant therapy with warfarin and Etodolac (Etova-MR) should not require dosage adjustment of either drug. However, caution should be exercised because there have been a few spontaneous reports of prolonged prothrombin times, with or without bleeding, in Etodolac (Etova-MR)-treated patients receiving concomitant warfarin therapy.

Drug/Laboratory Test Interactions

The urine of patients who take Etodolac (Etova-MR) can give a false-positive reaction for urinary bilirubin (urobilin) due to the presence of phenolic metabolites of Etodolac (Etova-MR). Diagnostic dip-stick methodology, used to detect ketone bodies in urine, has resulted in false-positive findings in some patients treated with Etodolac (Etova-MR). Generally, this phenomenon has not been associated with other clinically significant events. No dose relationship has been observed.

Etodolac (Etova-MR) treatment is associated with a small decrease in serum uric acid levels. In clinical trials, mean decreases of 1 to 2 mg/dL were observed in arthritic patients receiving Etodolac (Etova-MR) (600 mg to 1000 mg/day) after 4 weeks of therapy. These levels then remained stable for up to 1 year of therapy.

Dosage of Thiocolchicoside (Etova-MR) in details

Oral

Muscle spasms

Adult: Initially, 16 mg daily.

Intramuscular

Muscle spasms

Adult: Up to 8 mg daily.

Thiocolchicoside (Etova-MR) interactions

LEXOTAN undergoes hepatic microsomal oxidation via the cytochrome P450 liver enzymes.

Therefore, caution should be taken in patients taking medicines that inhibit the P450 liver enzymes (e.g. azole antifungals, macrolide antibiotics, HIV protease inhibitors, calcium channel blocking agents).

LEXOTAN undergoes oxidative metabolism and, consequently, may interact with disulfiram or cimetidine resulting in increased plasma levels of LEXOTAN. Patients should be observed closely for evidence of enhanced benzodiazepine response during concomitant treatment with either disulfiram or cimetidine; some patients may require a reduction in benzodiazepine dosage.

The benzodiazepines, including LEXOTAN, produce additive CNS depressant effects when coadministered with other medications which themselves produce CNS depression e.g. barbiturates, alcohol, sedatives, antidepressants, hypnotics, anxiolytics, phenothiazines and other antipsychotics,

skeletal muscle relaxants, antihistamines, narcotic analgesics and anaesthetics.

Alcohol should be avoided in patients receiving LEXOTAN.

In the case of narcotic analgesics enhancement of euphoria may also occur, leading to an increase in psychic drug dependence.

The anticholinergic effects of atropine and similar medicines, antihistamines and antidepressants may be potentiated.

Interactions have been reported between some benzodiazepines and anticonvulsants, with changes in the serum concentration of the benzodiazepine or anticonvulsant. It is recommended that patients be observed for altered responses when benzodiazepines and anticonvulsants are prescribed together and that serum level monitoring of the anticonvulsant be performed more frequently.

Interference with Clinical, Laboratory or Other Tests:

Minor EEG changes, usually low voltage fast activity, of no known clinical significance, has been

reported with benzodiazepine administration.
