Topical NSAIDs are medications sometimes used for back pain relief

The prescription of medications for back pain relief can be an effectieve early back pain treatment intervention. Depending on the patient’s clinical presentation, one or a combination of analgesics, muscle relaxants, and non-steroidal anti-inflammatory drugs (NSAIDs) might be recommended.

While medication use can be an effective back pain treatment early on, prolonged usage can have potential serious side effects such as addiction, drowsiness, gastrointestinal problems, as well as cardiovascular risks. In particular, some oral NSAIDs have been removed from the market because of these side effects, sparking the development of topical NSAIDs.

Topical NSAIDs are purported to have just as effective therapeutic effects without the potentially damaging side effects of their oral cousin. But are these topical NSAIDs an effective back pain treatment?

The Use of Topical NSAIDs

Here’s an article from Science-Based Pharmacy that does a nice job of looking at the medical evidence to support the use of topical NSAIDs.

Over the past two decades, evidence has emerged to demonstrate that topical versions of NSAIDs are well absorbed through the skin and reach therapeutic levels in synovial fluid; muscle, and fascia. With topical use, little drug actually circulates in the plasma, leading to levels that are a fraction of comparable oral doses. As adverse events from NSAIDs are largely dose-related, it’s expected (thought not as well documented) that serious side effects should be minimized.

For chronic conditions like osteoarthritis, the data are of fair quality and are persuasive. The National Institutes for Health and Clinical Excellence osteoarthritis guidelines provides a nice summary of the trials. Studies varied by site of osteoarthritis (knee, hand, hip, etc), the type of NSAID studied, the regimen, and trial design. On balance, there’s good evidence to show that topical NSAIDs are clinically- and cost-effective for short term (< 4 weeks) use, especially when pain is localized. Topical and oral versions seem to be similarly effective under these circumstances, and there there’s a significant reduction in non-serious adverse events with topical products. While there’s no conclusive evidence to demonstrate a reduction of serious adverse events, they’re expected to be better than oral products, given the blood levels are much lower. What impressed me is that topical NSAIDs are recommended as a preferred treatment before oral NSAIDs. And given many taking oral NSAIDs need to take stomach protecting drugs like omeprazole, the topical products, while more expensive than their oral versions, may actually be more cost-effective overall. A Cochrane review from 2010 is equally positive about the treatment of acute pain conditions. Forty-seven trials were included in their analysis that considered topical NSAIDs for strains, sprains, and overuse-type injuries. Compared to placebo, topical NSAIDs were evaluated to be effective, with few side effects, with a number needed to treat (NNT) of 4.5. About 6 or 7 out of 10 users can expect to achieve pain control with a topical NSAID, compared to 4 with a placebo. Side effects are comparable to placebo. And given systemic absorption is lower, the serious toxicity we associate with NSAIDs should be lessened, too. Not bad. Given there’s no long-term data with topical NSAIDs, the evidence doesn’t give us enough insight to understand the risk profile beyond a few weeks. Consequently it seems reasonable to try using topical products instead of oral products, particularly for intermittent, rather than chronic, pain conditions. While compounding pharmacies have made topical versions of NSAIDs for years, there’s little information on effectiveness and safety of these products. As commercial formulations are supported with pharmacokinetic and clinical studies demonstrating efficacy, they are the preparations of choice. Read Full Article >>>
