Etolyn

Etolyn Uses, Dosage, Side Effects, Food Interaction and all others data.

Etolyn is a non-steroidal anti-inflammatory drug (NSAID). It inhibits the formation of prostaglandins. The inhibition of prostaglandin synthesis observed with Etolyn differs from that of other NSAIDs. Studies in human cell models have confirmed that Etolyn is selective for the inhibition of COX-2. Experiments have shown Etolyn to have marked anti-inflammatory activity, being more potent than several clinically established NSAIDs.

Etolyn is an anti-inflammatory agent with analgesic and antipyretic properties. It is used to treat osteoarthritis, rheumatoid arthritis and control acute pain. The therapeutic effects of etodolac are achieved via inhibition of the synthesis of prostaglandins involved in fever, pain, swelling and inflammation. Etolyn is administered as a racemate. As with other NSAIDs, the S-form has been shown to be active while the R-form is inactive. Both enantiomers are stable and there is no evidence of R- to S- conversion in vivo.

Uses

Carefully consider the potential benefits and risks of etodolac capsules and other treatment options before deciding to use etodolac capsules. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.Etolyn are used:1. For acute and long-term use in the management of signs and symptoms of the following:

  • Osteoarthritis
  • Rheumatoid arthritis

2. For the management of acute pain

Etolyn is also used to associated treatment for these conditions: Chronic Back Pain, Extra-Articular Rheumatism, Juvenile Idiopathic Arthritis (JIA), Muscle Spasms, Nonspecific Pain Post Traumatic Injury, Osteoarthritis (OA), Pain, Acute, Postoperative pain, Rheumatoid Arthritis, Spinal Disorders

How Etolyn works

Similar to other NSAIDs, the anti-inflammatory effects of etodolac result from inhibition of the enzyme cycooxygenase (COX). This decreases the synthesis of peripheral prostaglandins involved in mediating inflammation. Etolyn binds to the upper portion of the COX enzyme active site and prevents its substrate, arachidonic acid, from entering the active site. Etolyn was previously thought to be a non-selective COX inhibitor, but it is now known to be 5 – 50 times more selective for COX-2 than COX-1. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.

Dosage

Etolyn dosage

Carefully consider the potential benefits and risks of Etolyn and other treatment options before deciding to use Etolyn capsules. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

After observing the response to initial therapy with Etolyn capsules, the dose and frequency should be adjusted to suit an individual patient's needs.

Dosage adjustment of Etolyn is generally not required in patients with mild to moderate renal impairment. Etolyn should be used with caution in such patients, because, as with otherNSAIDs, they may further decrease renal function in some patients with impaired renal function.

Analgesia: The recommended total daily dose of Etolyn for acute pain is up to 1000 mg, given as 200 to 400 mg every 6 to 8 hours. Doses of Etolyn greater than 1000 mg/day have not been adequately evaluated in well-controlled clinical trials.

Osteoarthritis and Rheumatoid Arthritis: The recommended starting dose is 300 mg b.i.d., t.i.d., or 400 mg b.i.d., or 500 mgb.i.d.A lower dose of 600 mg/day may suffice for long-term administration. Physicians should be aware that doses above 1000 mg/day have not been adequately evaluated in well-controlled clinical trials.

In chronic conditions, a therapeutic response to therapy with Etolyn is sometimes seen within one week of therapy, but most often is observed by two weeks. After a satisfactory response has been achieved, the patient's dose should be reviewed and adjusted as required.

Side Effects

The common side effects of Etolyn involve the gastrointestinal system. It can cause abdominal pain, constipation, diarrhea, dyspepsia, flatulence, heartburn, nausea, GI ulcers, vomiting. Other events including abnormal renal function, anemia, dizziness, edema, elevated liver enzymes, headaches, increased bleeding time, pruritis, rashes, tinnitus etc.

Toxicity

Selective COX-2 inhibitors have been associated with increased risk of serious cardiovascular events (e.g. myocardial infarction, stroke) in some patients. Current data is insufficient to assess the cardiovascular risk of etodolac. Etolyn may increase blood pressure and/or cause fluid retention and edema. Risk of GI toxicity including bleeding, ulceration and perforation. Risk of direct renal injury, including renal papillary necrosis. Anaphylactoid and serious skin reactions (e.g. exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported. Common adverse events include abdominal pain, constipation, diarrhea, dyspepsia, flatulence, GI bleeding, GI perforation, nausea, peptic ulcer, vomiting, renal function abnormalities, anemia, dizziness, edema, liver function test abnormalities, headache, prolonged bleeding time, pruritus, rash, tinnitus. Symptoms of overdose include lethargy, drowsiness, nausea, vomiting, and epigastric pain.

Precaution

Etolyn should be given with caution in patients with severe hepatic reactions, pre-existing asthma, fluid retention, hypertension or heart failure. If clinical sings and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g. eosinophilia, rash etc.), it should be discontinued.

Interaction

Since Etolyn is extensively protein-bound, it may be necessary to modify the dosage of other highly protein-bound drugs. The concomitant administration of Warfarin and Etolyn should not require a dosage adjustment of either drug, however it has rarely led to prolonged prothrombin times, therefore caution should be exercised when Etolyn is administered with Warfarin. Concomitant use of Ciclosporin, Methotrexate, Digoxin, or Lithium with NSAIDs may cause an increase in serum levels of these compounds and associated toxicities. Care should also be taken in patients treated with any of the following drugs as interactions have been reported in some patients: Anti-hypertensives, Mifepristone, other Analgesics, Corticosteroids and Quinolone Antibiotics.

Food Interaction

  • Avoid alcohol.
  • Take with food. Food reduces irritation.

Etolyn Alcohol interaction

[Moderate] GENERALLY AVOID:

The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss.

The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.



Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Etolyn Hypertension interaction

[Major] Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Therapy with NSAIDs should be administered cautiously in patients with preexisting fluid retention, hypertension, or a history of heart failure.

Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.

Hypertension interaction

[Moderate] Nonsteroidal anti-inflammatory drugs (NSAIDs), including topicals, can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events.

NSAIDs 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.

Elimination Route

It is not known whether etodolac is excreted in human milk; however, based on its physical-chemical properties, excretion into breast milk is expected. Etolyn is extensively metabolized in the liver. The hydroxylated-etodolac metabolites undergo further glucuronidation followed by renal excretion and partial elimination in the feces (16% of dose). Approximately 1% of a etodolac dose is excreted unchanged in the urine with 72% of the dose excreted into urine as parent drug plus metabolite.

Pregnancy & Breastfeeding use

Pregnancy: There are no adequate and well-controlled studies in pregnant women. It should be use in pregnancy only if the potential benefit justifies the potential risk to the fetus.

Lactation: It is not known whether Etolyn is excreted in human milk. 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.

Contraindication

Etolyn is contraindicated in patients with known hypersensitivity to Etolyn. Etolyn should not be given to patients who have experienced asthma, urticaria or other allergic-type reactions after taking Aspirin or other NSAIDs.

Acute Overdose

Symptoms following acute NSAID overdose are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain which are generally reversible with supportive care.
