analgesic effect of a new analgesic based gel(douloff) versus oral paracetamol in acute soft injuries

Conditions: Analgesia

Summary: herbal medicine is commonly used to treat pain, but little is known about its effectiveness and its place in the common arsenal of analgesics .the question of whether such herbal combinations could have similar efficacy to oral analgesics in the treatment of post-traumatic soft tissue pain has not yet been investigated. thus, we conducted this multi-center randomized controlled trial to determine the efficacy and tolerability of a new topical herbal preparation (douloff®) compared to oral paracetamol in the treatment of acute pain secondary to soft tissue injury.

patients are eligible for enrollment if they are over 60 years of age, present to the emergency department with minor non-penetrating musculoskeletal soft tissue trauma occurring within 24 hours prior to admission to the emergency department, and require a prescription for home analgesic treatment at discharge: pain on movement (pom) with an intensity\> 50 on a visual numeric scale (vns) ranging from 0 to 10 (0 = no pain, 10 = maximum pain) exclusion criteria are: skin lesions (dryness or excessive redness of the skin, atopic dermatitis and eczema) in the painful area, presence of a wound, joint dislocation or multiple injuries, fracture , patients with severe trauma (injury severity score \> 16), the need for hospitalization or surgery, daily use of nsaids or other analgesics in the 2 weeks before presentation, and previous treatment with analgesia for the same injury, pregnant or lactating women , inability to use the vns pain score, refusal to consent, or refusal to communicate patients are ineligible if they have contraindications to any of the drugs in the protocol, including a history of previous adverse events or a known allergy or hypersensitivity. patients are randomly assigned (1:1) to receive douloff or oral paracetamol.randomization is performed centrally according to a computer-generated random list by a blinded research associate not involved in any other part of the trial. the subjects included are divided into two groups: the new gel (douloff® group) or oral paracetamol (paracetamol group). all treatments in the protocol are numbered according to the randomization sequence by an independent research associate who is not involved in the monitoring or follow-up of the subjects. the topical study treatment is applied to the injured site 3 times daily for 7 days. the gel should be applied gently to the skin of the injured site for 1 minute. to minimize additional sources of response variability, adhesive and/or immobilizing casts, bandages, splints, and ice application are prohibited after randomization. patients should be instructed to prevent water or moisture from contacting the affected area after application of topical therapy. paracetamol is administered orally (1g three times daily). the primary endpoint is the frequency of pain resolution defined as at least a 50% reduction in pain level (vns) at day 7 compared with the ed discharge vns (vns d0) during movement (dam). secondary end points included delta vns, which is the change in vns score from ed discharge (vns d0) to 7 days later (vns d7). the delta vns is calculated as \[(vns d0 - vns d7 / vns d0) x 100\]. time to achieve pain resolution criteria, need for rescue analgesia, patient satisfaction, and rate of adverse events are also considered secondary endpoints. failure to apply the gel more than three times during a treatment period constituted poor adherence.
