What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing two types of injections, ketorolac and triamcinolone, to help patients with painful conditions in their shoulder, elbow, wrist, and hand. These injections aim to reduce inflammation and pain, improving movement and function. Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) known for its potent nonopioid pain-relieving activity, effective in treating moderate to severe pain, especially after surgery.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is it safe to use Ketorolac and Triamcinolone injections in humans?

Triamcinolone injections are commonly used for various conditions, but they can have harmful effects like tendon damage. Ketorolac has been tested for safety in animals, but specific human safety data is limited. ^{1 2 3 4 5}

How do ketorolac and triamcinolone injections differ from other drugs for tendinopathy or arthritis?

Ketorolac and triamcinolone injections are unique because they offer different mechanisms of action: ketorolac is a non-steroidal anti-inflammatory drug (NSAID) that reduces pain and inflammation, while triamcinolone is a corticosteroid that provides longer-lasting anti-inflammatory effects. This combination provides a novel approach by potentially offering both immediate and sustained relief for tendinopathy or arthritis. ^{1 3 4 6 7}

What data supports the effectiveness of the drugs Ketorolac and Triamcinolone for tendinopathy or arthritis?

Research shows that triamcinolone injections can be more effective than ketorolac in relieving symptoms of trigger digits, a condition similar to tendinopathy, especially in the short term. However, ketorolac and triamcinolone had similar long-term outcomes in terms of symptom resolution. ^{1 4 7 8 9}

Participants will receive the triamcinolone injection solutions in a standard fashion. Injections will be performed using the treating physician's standard technique.

Group II: Ketorolac injection to the shoulder, elbow, wrist, or hand Active Control 1 Intervention

Participants will receive the Ketoralac injection solutions in a standard fashion. Injections will be performed using the treating physician's standard technique.

Published Research Related to This Trial

In a study of 121 patients with trigger digits, triamcinolone acetonide injections showed significantly better short-term efficacy compared to ketorolac trometamol, with 54% of patients achieving complete resolution of triggering at 6 weeks versus 0% in the ketorolac group.

While both treatments had similar long-term outcomes at 24 weeks, triamcinolone provided superior pain relief and reduced flexion deformity in the initial weeks, indicating it may be the preferred option for early intervention.

A low dose of 0.1 mg/mL of triamcinolone acetonide (TA) caused temporary changes in cell morphology and increased apoptosis in rotator cuff-derived cells, but these effects were reversible by 21 days.

In contrast, a high dose of 1.0 mg/mL of TA resulted in irreversible damage to cell morphology and viability, indicating that higher doses are unsafe for treating tendinopathy, and a re-administration interval of more than three weeks is necessary to avoid adverse effects.

In a study involving 57 participants with chronic rotator cuff tendinopathy, both subcutaneous 5% dextrose and corticosteroid injections significantly reduced pain, with dextrose showing a nearly significant advantage in pain reduction one month after treatment.

The 5% dextrose treatment was found to be at least as effective as corticosteroids for pain relief, and importantly, no serious adverse effects were reported in either treatment group.

In a study of 32 patients with external shoulder impingement syndrome, ketorolac injections led to significantly greater improvements in shoulder function and patient satisfaction compared to triamcinolone injections after 4 weeks.

Both treatments were effective in reducing pain and improving range of motion, but ketorolac showed superior results in the UCLA shoulder rating scale, suggesting it may be a safer alternative to corticosteroids with fewer potential side effects.

In a study involving rat Achilles tendons, the addition of platelet-rich plasma (PRP) to triamcinolone acetonide (TA) injections significantly prevented the negative effects of TA, such as reduced tendon strength and stiffness, which were observed in the TA-only group.

Histological analysis showed that PRP administration prevented harmful changes in tendon structure caused by TA, suggesting that PRP could serve as a protective agent for patients receiving corticosteroid injections for sports injuries.

In a study involving 30 children with non-infectious uveitis, subtenon triamcinolone acetonide (STA) injections showed significant efficacy, with 85.4% of eyes experiencing inflammation improvement and 77.8% resolution of macular edema at the 3-month follow-up.

The procedure was safe, with no immediate complications reported, and only a 12.5% incidence of ocular hypertension at 6 months, indicating that STA injections are a well-tolerated treatment option for pediatric patients.

In a study of 31 eyes from 30 patients, subconjunctival injections of triamcinolone acetonide significantly improved visual acuity and reduced central macular thickness over 12 months, indicating its efficacy in treating uveitic macular edema.

The treatment was found to be safe, with no significant increase in intraocular pressure and only one cataract diagnosed, which occurred in an uninjected eye, suggesting minimal risk of adverse effects.

In a study involving 15 rabbits, intraocular injections of preservative-free ketorolac tromethamine showed no significant adverse effects on retinal function or intraocular pressure compared to control eyes, indicating its safety for use.

The drug had a short elimination half-life of 2.3 hours in the vitreous, and no histopathological changes were observed, suggesting that ketorolac could be a viable alternative to steroid injections for treating intraocular conditions.

In a study involving 52 patients with shoulder impingement syndrome, low-volume corticosteroid injections (4 cc) provided similar pain relief and functional outcomes compared to high-volume injections (10 cc), indicating that less medication can be just as effective.

Both injection methods resulted in significant pain reduction over time, with no statistically significant differences in outcomes, suggesting that low-volume injections may be a safer and more efficient option for treating this condition.
