These studies suggest that various medications, including corticosteroids, opioids, hyaluronic acid-based treatments, NSAIDs, duloxetine, COX-2 inhibitors, omega-3 PUFAs, and nutraceuticals, can reduce joint pain and improve function, but some may have potential adverse effects or require further investigation for safety and efficacy.

Corticosteroids, commonly used for conditions like rheumatoid arthritis and osteoarthritis, offer moderate short-term relief from joint pain and improved function. However, their benefits typically last only a few weeks and do not provide long-term effectiveness. More concerning are the potential adverse effects, which include toxicity to articular cartilage and systemic side effects such as increased blood glucose levels, reduced immune function, and a heightened risk of infections.
Opioids, including oral and transdermal forms, are sometimes prescribed for severe osteoarthritis pain when other analgesics are contraindicated. While they do offer some pain relief and functional improvement, the benefits are modest. More importantly, opioids are associated with a significant increase in adverse events, including a higher risk of addiction, withdrawal symptoms, and serious side effects. The clinical relevance of their pain-relieving effects is also questionable.
NSAIDs are widely used to manage joint pain in conditions like osteoarthritis and temporomandibular disorders. They are effective in reducing pain and improving function but come with significant side effects, including gastrointestinal complications, renal disturbances, and cardiovascular events. These risks necessitate careful consideration when prescribing NSAIDs for long-term use .
Recent studies have explored novel formulations like hyaluronic acid-liposomal dexamethasone-diclofenac nanoparticles, which aim to reduce joint pain with fewer side effects. These formulations have shown promise in preclinical studies, offering prolonged pain relief without significant toxicities.
Duloxetine, a serotonin-norepinephrine reuptake inhibitor, has been found to reduce joint pain in postmenopausal women undergoing treatment with aromatase inhibitors for early-stage breast cancer. This medication offers a new option for managing joint pain in this specific patient population, potentially allowing them to continue their cancer treatment with fewer musculoskeletal symptoms.
Omega-3 PUFAs have been shown to reduce joint pain intensity, morning stiffness, and the number of painful joints in conditions like rheumatoid arthritis and inflammatory bowel disease. They also help decrease NSAID consumption, making them an attractive adjunctive treatment for inflammatory joint pain.
While various medications are available to manage joint pain, many come with significant risks and side effects. Corticosteroids and opioids offer limited long-term benefits and pose substantial risks. NSAIDs, although effective, also carry serious side effects. Alternative treatments like duloxetine for specific conditions and omega-3 PUFAs as adjunctive therapy show promise but require further research. Understanding these risks and benefits is crucial for optimizing joint pain management strategies.
