Relafen vs Ibuprofen
Introduction
For patients with chronic pain, arthritis or inflammation, certain drugs that inhibit the activity of cyclooxygenase enzymes, which are responsible for producing prostaglandins causing pain and inflammation in the body, can help in managing discomfort. Relafen (nabumetone) and Ibuprofen are two such drugs that are prescribed for these conditions. They each impact different aspects of the inflammatory response but both have analgesic and anti-inflammatory effects. Nabumetone is a non-acidic NSAID that requires hepatic metabolism to form an active metabolite impacting prostaglandin synthesis. On the other hand, ibuprofen is classified as a propionic acid derivative NSAID directly inhibiting cyclooxygenase enzymes COX-1 and COX-2 thereby reducing levels of prostaglandins.
What is Relafen?
Nabumetone (the generic name for Relafen) was a significant development in the class of nonsteroidal anti-inflammatory drugs (NSAIDs). It first gained FDA approval in 1991. Relafen works by reducing levels of certain chemicals that cause inflammation and pain in the body, providing relief to those with conditions like osteoarthritis or rheumatoid arthritis. Its selective inhibition of COX-2 enzymes results in less gastrointestinal irritation compared to other NSAIDs that inhibit both COX-1 and COX-2.
Ibuprofen, another member of the NSAID family but available over-the-counter, also reduces chemicals causing pain and inflammation but is not as selective as Relafen. Therefore, it might lead to more substantial side effects such as stomach upset or ulcers, especially when used long-term or at high doses. Both medications should be used under medical advice considering individual health profiles.
What conditions is Relafen approved to treat?
Relafen (nabumetone) is approved for the treatment of various pain-related conditions:
- Osteoarthritis, a common form of arthritis that causes cartilage breakdown in joints.
- Rheumatoid arthritis, an autoimmune disease causing inflammation and pain in the joints.
These are similar to some uses of Ibuprofen, however Relafen specifically targets these two forms of arthritis.
How does Relafen help with these illnesses?
Relafen, known generically as nabumetone, helps manage pain and inflammation by inhibiting the production of prostaglandins in the body. It accomplishes this by blocking an enzyme called cyclooxygenase which is involved in prostaglandin synthesis. Prostaglandins are lipid compounds that play a significant role in dealing with injury or illness, including inducing inflammation and fever to protect the body. They also enhance sensation to pain at the site of injury. Therefore, by reducing prostaglandin levels, Relafen can limit negative effects such as swelling, pain or fever associated with conditions like arthritis. This makes it easier for patients to manage their symptoms and improve their quality of life.
What is Ibuprofen?
Ibuprofen, marketed under various brand names such as Advil and Motrin, is a non-steroidal anti-inflammatory drug (NSAID) that reduces the production of prostaglandins by inhibiting cyclooxygenase enzymes. This action results in decreased inflammation and pain. It was first approved by the FDA in 1974. Unlike Relafen (nabumetone), another NSAID, Ibuprofen does not need to be metabolized in the liver to its active form which gives it a faster onset of action. Its side-effect profile also differs from that of other NSAIDs like Relafen; for instance, it's less likely to cause gastrointestinal upset or ulcers at low doses. Common side effects can include stomach pain and swelling (edema). The ability of ibuprofen to reduce fever and provide relief from mild-to-moderate pain makes it an excellent choice for conditions like osteoarthritis and rheumatoid arthritis as well as other painful disorders or syndromes where inflammation is often an underlying factor.
What conditions is Ibuprofen approved to treat?
Ibuprofen is approved for the management of:
- Mild to moderate pain
- Primary dysmenorrhea (painful menstrual cramps)
- Fever reduction
- Inflammatory conditions such as rheumatoid arthritis and osteoarthritis
How does Ibuprofen help with these illnesses?
Ibuprofen, similar to Relafen, works by inhibiting the synthesis of prostaglandins—substances in the body that cause inflammation. This mechanism aids in reducing pain and inflammation. Ibuprofen achieves this by blocking cyclooxygenase (COX) enzymes which are heavily involved in the formation of prostaglandins. It's often preferred as a first line treatment due to its efficacy and lower cost compared to other NSAIDs like Relafen. Furthermore, ibuprofen's action on platelet aggregation also plays a role since it can reduce blood clotting, unlike Relafen which has no significant effect on this process. Thus, while both drugs have their place for treating various conditions associated with pain and inflammation, ibuprofen is sometimes chosen when there's a need to manage symptoms alongside risk factors such as heart disease or stroke.
How effective are both Relafen and Ibuprofen?
Both nabumetone (Relafen) and ibuprofen have established histories of success in treating patients with various inflammatory conditions such as osteoarthritis and rheumatoid arthritis. They were initially approved by the FDA only a few years apart. Since they act on different enzymes, they may be prescribed under different circumstances. The effectiveness of nabumetone and ibuprofen in alleviating symptoms was directly studied in several clinical trials; both drugs exhibited similar efficacy in managing pain as well as inflammation.
A 2001 review demonstrated that nabumetone is effective from the first week of treatment, has a side effect profile comparable to other NSAIDs, and is generally well-tolerated even among elderly populations who commonly use this class of drug for chronic pain management due to conditions like arthritis. The same study reports that nabumetone has become widely used around the world due its unique pharmacology which allows it to have less gastrointestinal side effects compared to traditional NSAIDs.
On the other hand, a 2016 meta-analysis indicated that ibuprofen seems more effective than placebo at relieving acute pain episodes but also comes with its fair share of potential side-effects including increased risk for cardiovascular events especially when consumed at high doses over extended periods. Nonetheless, it remains an essential medicine according to WHO list because its wide array of uses ranging from fever reduction to anti-inflammation making it one of the most versatile drugs available over-the-counter.
At what dose is Relafen typically prescribed?
Oral dosages of Relafen (nabumetone) typically range from 1000-2000 mg/day for the relief of signs and symptoms of osteoarthritis or rheumatoid arthritis. However, studies have shown that starting with a dose of 1000 mg/day can be sufficient in treating these conditions in most adults. For children and adolescents, dosage should be determined by a healthcare professional based on the patient's weight and severity of condition. In either population, dosage can be increased after several weeks if there is insufficient response to treatment. The maximum daily dose that should not be exceeded is 2000 mg.

Contraindications for Relafen and Ibuprofen?
Both Relafen and Ibuprofen, like all nonsteroidal anti-inflammatory drugs (NSAIDs), may increase the risk of heart attack or stroke in some people. If you notice any cardiovascular symptoms such as chest pain, shortness of breath, weakness on one side of your body or slurred speech while taking either medication, seek immediate medical attention.
Neither Relafen nor Ibuprofen should be taken if you are currently using a class of drugs called angiotensin-converting enzyme (ACE) inhibitors for hypertension or other cardiovascular conditions. Always inform your doctor about all medications you're currently taking; ACE inhibitors can interact negatively with both Relafen and Ibuprofen by reducing their effectiveness and potentially causing kidney problems. It's also important to note that long-term use of NSAIDs can lead to gastrointestinal issues such as stomach bleeding or ulcers.
How much do Relafen and Ibuprofen cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Relafen (500 mg) averages around $200, which works out to $3.33/day if you are on a dose of 1000 mg per day.
- The price for ibuprofen varies depending on its over-the-counter or prescription status. A common average cost for a bottle containing 50 tablets (200mg each) ranges from $10 to $15, working out to about $0.20 - $0.60/day based on typically recommended doses.
Thus, if you are in need of long-term anti-inflammatory treatment, generic ibuprofen may be less expensive compared to higher-dosed Relafen treatments.
For the generic versions of these drugs:
- Nabumetone (the active ingredient in Relafen; available as 500mg and 750mg tablets), is available in packs ranging from 30 up to hundreds with costs depending upon quantity purchased and dosage required – typical daily costs can range anywhere between ~$1-$3 per day.
- Generic ibuprofen comes in various pack sizes with prices varying accordingly but it's generally more affordable than nabumetone with daily costs often not exceeding about ~$1 even at doses like 600 mg three times a day (~1800mg).
Please note that cost should not be your only consideration when deciding which drug is most suitable for you - efficacy and tolerability matter too!
Popularity of Relafen and Ibuprofen
Nabumetone, available under the brand name Relafen, was estimated to have been prescribed to just over 1 million people in the US in 2020. It is a nonsteroidal anti-inflammatory drug (NSAID) used for treating pain or inflammation caused by arthritis. Nabumetone accounted for just over 5% of NSAID prescriptions in the US and has seen a steady prevalence since its introduction.
Ibuprofen, including popular brand versions such as Advil and Motrin, was prescribed to approximately 20 million people in the USA during 2020. In the US, ibuprofen accounts for around half of all over-the-counter NSAID sales and about one third of prescription NSAID sales. The ubiquity of ibuprofen can be attributed to its efficacy as an analgesic (painkiller), antipyretic (fever reducer), and anti-inflammatory medication combined with its relative safety profile when taken as directed. Ibuprofen's popularity has remained relatively stable throughout recent years.
Conclusion
Both Relafen (nabumetone) and ibuprofen have a long-standing record of usage in patients with pain, inflammation or fever, and are backed by numerous clinical studies indicating that they are more effective than placebo treatments. In some cases, the drugs may be combined, but this is subject to careful consideration by a physician as they also carry risks when used together. Due to their different mechanisms of action—with Relafen being a non-acidic NSAID that inhibits prostaglandin synthesis, and ibuprofen acting as an anti-inflammatory drug—they tend to be prescribed under different circumstances. Ibuprofen is considered a first-line treatment option for mild-to-moderate pain and fever reduction while Relafen would usually be considered for chronic conditions like osteoarthritis or rheumatoid arthritis.
Both drugs are available in generic form which represents significant cost savings especially for patients who must pay out-of-pocket. Both Relafen and ibuprofen may require an adjustment period meaning effects may not be noticeable right away.
The side effect profile is similar between the two drugs; both being generally well-tolerated but with ibuprofen possibly causing more gastrointestinal issues than Relafen due to its mechanism of action on COX-1 enzymes. For both drugs however, patients must monitor any unusual symptoms especially when starting treatment, and should seek medical help immediately if they notice severe stomach pain or bloody stools indicative of potential gastric bleeding.
