Rheumatoid arthritis dosage

Adult dosing for osteoarthritis and rheumatoid arthritis dosage is 7.5-15 mg PO qd. Practitioners should prescribe the lower dose of 7.5 mg PO qd and advance to 15 mg PO qd if lower dose proves ineffective in treating symptoms [1,5]. 

Uses. Aspirin has analgesic, antiinflammatory, and antipyretic activity. It is used for the reHef of less severe types of pain, such as headache, neuritis, acute and chronic rheumatoid arthritis, and toothache. Aspirin can be purchased in a variety of OTC and prescription dosage forms made and formulated by many companies. Tablets, ie, buffered, plain, or enteric-coated, are the most familiar in the United States, but other forms such as powder and effervescent formulations are of considerable importance in other parts of the world. 

Rheumatoid Arthritis CHAPTER 4 Dosage Regimens for Nonsteroidal Antiinflammatory Drugs ... 

Osteoarthritis/rheumatoid arthritis 500 mg to 1 g/day in 2 divided doses. Individualize dosage. Do not exceed maintenance doses higher than 1.5 g/day. 

Rheumatoid arthritis - Recommended oral dosage is 100 to 200 mg twice a day. 

Rheumatoid arthritis - 150 to 200 mg/day in divided doses (50 mg 3 or 4 times/day [diclofenac sodium or potassium] or 75 mg twice/day [diclofenac sodium]). Dosages greater than 225 mg/day of the delayed-release diclofenac sodium formulation and dosages greater than 200 mg/day of immediate-release diclofenac potassium formulation are not recommended. 

In acute flares of chronic rheumatoid arthritis, it may be necessary to increase the dosage by 25 or 50 mg/day. 

Arthritis - Use the lowest dosage for each patient. For treatment of osteoarthritis and rheumatoid arthritis, the recommended starting and maintenance dose is 7.5 mg once/day. Some patients may receive additional benefit by increasing the dose to 15 mg once/day. The maximum recommended dose is 15 mg/day. 

Osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis - Initial dosage is 150 mg twice a day. 

Rheumatoid arthritis PO Initially, 400-600 mg (310-465 mg base) daily for 5-10 days, gradually increased to optimum response level. Maintenance (usually within 4-12 wk) Dosage decreased by 50% and then continued at maintenance dose of 200-400 mg/day. Maximum effect may not be seen for several months. 

Azathioprine is approved for use in rheumatoid arthritis and is used at a dosage of 2 mg/kg/d. Controlled trials show efficacy in psoriatic arthritis, reactive arthritis, polymyositis, systemic lupus erythematosus, and Behget s disease. 

Although antimalarials improve symptoms, there is no evidence that these compounds alter bony damage in rheumatoid arthritis at their usual dosages (up to 6.4 mg/kg/d for hydroxychloroquine or 200 mg/d for chloroquine). It usually takes 3-6 months to obtain a response. Antimalarials are often used in the treatment of the skin manifestations, serositis, and joint pains of systemic lupus erythematosus, and they have been used in Sjogren s syndrome. 

Cyclophosphamide is active against rheumatoid arthritis when given orally at dosages of 2 mg/kg/d but not when given intravenously. It is used regularly to treat systemic lupus erythematosus, vasculitis, Wegener s granulomatosis, and other severe rheumatic diseases. 

Cyclosporine is approved for use in rheumatoid arthritis and retards the appearance of new bony erosions. Its usual dosage is 3-5 mg/kg/d divided into two doses. Anecdotal reports suggest that it may be useful in systemic lupus erythematosus, polymyositis and dermatomyositis, Wegener s granulomatosis, and juvenile chronic arthritis. 

MMF is effective for the treatment of renal disease due to systemic lupus erythematosus and may be useful in vasculitis and Wegener s granulomatosis. Although MMF is occasionally used at a dosage of 2 g/d to treat rheumatoid arthritis, there are no well-controlled data regarding its efficacy in this disease. 

Adalimumab is given subcutaneously and has a half-life of 10-20 days. Its clearance is decreased by more than 40% in the presence of methotrexate, and the formation of human antimonoclonal antibody is decreased when methotrexate is given at the same time. The usual dose in rheumatoid arthritis is 40 mg every other week, although increased responses may be evident at higher dosages. In psoriasis, 80 mg is given at week 0, 40 mg at week 1, and then 40 mg every other week thereafter. 

A 47-year-old woman developed a gastrocolic fistula during treatment with aspirin (dosage and duration of therapy not stated) and prednisone for chronic rheumatoid arthritis (148). 

Brief History. R.F., a 63-year-old woman, has been receiving treatment for schizophrenia intermittently for many years. She was last hospitalized for an acute episode 7 months ago and has since been on a maintenance dosage of haloperi-dol (Haldol), 25 mg/d. She is also being seen as an outpatient for treatment of rheumatoid arthritis in both hands. Her current treatment consists of gentle heat and active range-of-motion exercises, three times each week. She is being considered for possible metacarpophalangeal joint replacement. 

The efficacy of flurbiprofen at dosages of 200-400 mg/d is comparable to that of aspirin and other NSAIDs in clinical trials for patients with rheumatoid arthritis, ankylosing spondylitis, gout, and osteoarthritis. It is also available in a topical ophthalmic formulation for inhibition of intraoperative miosis. Flurbiprofen intravenously has been found to be effective for perioperative analgesia in minor ear, neck, and nose surgery and in lozenge form for sore throat. 

The effectiveness of ketoprofen at dosages of 100-300 mg/d is equivalent to that of other NSADDs in the treatment of rheumatoid arthritis, osteoarthritis, gout, dysmenorrhea, and other painful conditions. In spite of its dual effect on prostaglandins and leukotrienes, ketoprofen is not superior to other NSAIDs. Its major adverse effects are on the gastrointestinal tract and the central nervous system.
