Tolmetin, sold under the brand name Tolectin among others, is a medication used to treat inflammation in conditions such as osteoarthritis and rheumatoid arthritis.[1] It is taken by mouth.[1] Benefits are generally seen within a week.[2]

Common side effects include abdominal pain, diarrhea, swelling, dizziness, and increased blood pressure.[1] Other side effects can include kidney problems, liver problems, heart disease, Stevens-Johnson syndrome, and anaphylaxis.[1] Use in the last part of pregnancy may harm the baby, while use when breastfeeding is safe.[1][2] It is a nonsteroidal anti-inflammatory drug (NSAID) and inhibits both COX-1 and COX-2.[1]

Tolmetin was approved for medical use in the United States in 1976.[1] It is available as a generic medication.[3] In the United States 60 tablets of 600 mg costs about 96 USD as of 2021.[3] It is not available in the United Kingdom.[4]

Medical uses

Tolmetin is applicable in the treatment of rheumatoid arthritis,[5][6] osteoarthrosis,[7][8] pain,[9] and ankylosing spondylitis.[10]

Dosage

The typical dose is 400 mg three times per day.[2]

Side effects

Tolmetin can increase the risk of heart or circulatory conditions such as heart attacks and strokes. It should not be taken shortly before or after coronary artery bypass surgery.[11] Tolmetin can also increase the risk of gastrointestinal conditions such as perforation or bleeding, which is fatal. Antacids can be taken with tolmetin to relieve stomachaches that often occur.[11] Overdose can result in drowsiness, nausea, epigastric pain, and vomiting.

In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result from low amniotic fluid.[12][13] They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.[12][13]

Mechanism of action

Although the mechanism of action of tolmetin is unknown, research involving humans and animals has shown that tolmetin does not achieve anti-inflammatory response by stimulation of the adrenal or pituitary gland, but it has shown tolmetin restrains prostaglandin synthetase in vitro and reduces plasma levels of prostaglandin E, possibly causing the anti-inflammatory response.

When tested in rats tolmetin prevented experimentally stimulated polyarthritis and reduced inflammation. In patients with rheumatoid arthritis or osteoarthritis tolmetin restrained disease activity as efficiently as aspirin and indometacin, although the occurrence of mild gastrointestinal adverse effects and tinnitus was lower in patients treated with tolmetin than it was with aspirin-treated patients and the occurrence of adverse effects of the central nervous system was lower with tolmetin than it was with indometacin.[14]
