12.1 Mechanism of Action Indomethacin has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of indomethacin capsules, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Indomethacin is a potent inhibitor of prostaglandin synthesis in vitro . Indomethacin concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because indomethacin is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.

Indomethacin capsules are indicated for: Moderate to severe rheumatoid arthritis including acute flares of chronic disease Moderate to severe ankylosing spondylitis Moderate to severe osteoarthritis Acute painful shoulder (bursitis and/or tendinitis) Acute gouty arthritis Indomethacin capsules are nonsteroidal anti-inflammatory drug indicated for: Moderate to severe rheumatoid arthritis including acute flares of chronic disease Moderate to severe ankylosing spondylitis Moderate to severe osteoarthritis Acute painful shoulder (bursitis and/or tendinitis) Acute gouty arthritis ( 1 )

Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals. ( 2.1 ) The dosage for moderate to severe rheumatoid arthritis including acute flares of chronic disease; moderate to severe ankylosing spondylitis; and moderate to severe osteoarthritis is indomethacin capsules 25 mg two or three times a day. ( 2.2 ) The dosage for acute painful shoulder (bursitis and/or tendinitis) is 75 to 150 mg daily in 3 or 4 divided doses. ( 2.3 ) The dosage for acute gouty arthritis is indomethacin capsules 50 mg three times a day. ( 2.4 ) 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of indomethacin capsules and other treatment options before deciding to use indomethacin capsules. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see (5) ]. After observing the response to initial therapy with indomethacin, the dose and frequency should be adjusted to suit an individual patient’s needs. generally appear to correlate with the dose of indomethacin. Therefore, every effort should be made to determine the lowest effective dosage for the individual patient. Dosage recommendations for active stages of the following: 2.2 Moderate to severe rheumatoid arthritis including acute flares of chronic disease; moderate to severe ankylosing spondylitis; and moderate to severe osteoarthritis Indomethacin capsules 25 mg twice a day or three times a day. If this is well tolerated, increase the daily dosage by 25 mg or by 50 mg, if required by continuing symptoms, at weekly intervals until a satisfactory response is obtained or until a total daily dose of 150 to 200 mg is reached. Doses above this amount generally do not increase the effectiveness of the drug. In patients who have persistent night pain and/or morning stiffness, the giving of a large portion, up to a maximum of 100 mg, of the total daily dose at bedtime may be helpful in affording relief. The total daily dose should not exceed 200 mg. In acute flares of chronic rheumatoid arthritis, it may be necessary to increase the dosage by 25 mg or, if required, by 50 mg daily. If minor adverse effects develop as the dosage is increased, reduce the dosage rapidly to a tolerated dose and observe the patient closely. If severe occur, stop the drug....

The following are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events [see ( 5.1 )] GI Bleeding, Ulceration and Perforation [see ( 5.2 )] Hepatotoxicity [see ( 5.3 )] Hypertension [see ( 5.4 )] Heart Failure and Edema [see ( 5.5 )] Renal Toxicity and Hyperkalemia [see ( 5.6 )] Anaphylactic Reactions [see ( 5.7 )] Serious Skin Reactions [see ( 5.9 )] Hematologic Toxicity [see ( 5.12 )] Most common (incidence ≥ 3%) are headache, dizziness, dyspepsia and nausea.

In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving indomethacin capsules than in the group taking indomethacin suppositories or placebo. In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with indomethacin capsules or suppositories was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group. The for indomethacin capsules listed in the following table have been arranged into two groups: (1) incidence greater than 1%; and (2) incidence less than 1%. The incidence for group (1) was obtained from 33 double-blind controlled clinical trials reported in the literature (1,092 patients). The incidence for group (2) was based on reports in clinical trials, in the literature, and on voluntary reports since marketing. The probability of a causal relationship exists between indomethacin capsules and these , some of which have been reported only rarely. The reported with indomethacin capsules may occur with use of the suppositories. In addition, rectal irritation and tenesmus have been reported in patients who have received the capsules....

Indomethacin capsules are contraindicated in the following patients: Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to indomethacin or any components of the drug product [see ( 5.7 , 5.9) ] . History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients [see ( 5.7 , 5.8) ] . In the setting of coronary artery bypass graft (CABG) surgery [see ( 5.1 )]. Known hypersensitivity to indomethacin or any components of the drug product. ( 4 ) History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. ( 4 ) In the setting of CABG surgery. ( 4 )
