Clinical Response of Nuberol Forte in Chronic Neck Pain in Routine Rehabilitation Centers

Completed
Conditions
Chronic Neck Pain
Interventions
Drug: Nuberol Forte
Registration Number
NCT06628466
Lead Sponsor
The Searle Company Limited Pakistan
Brief Summary

Globally, the prevalence of neck pain ranges from 16.7% to 75.1%. Despite conducting multiple studies on specific subject pools in Pakistan, primarily focusing on professional-related neck pain, there is a lack of accurate data to determine the local prevalence of neck pain or the effective management of neck pain through physical therapy and pharmacological intervention. The purpose of this study is to evaluate the clinical effectiveness of paracetamol and orphenadrine (Nuberol Forte) when combined with physical therapy in Pakistani patients suffering from neck pain at regular rehabilitation centers.

Detailed Description

For most cases of neck pain, the risk factors are multifactorial, and clear pathophysiological mechanisms are lacking. Treatment efforts aim to alleviate symptoms in the absence of causal treatment alternatives, while rehabilitation programs enhance the functional status. Therefore, it is imperative to have validated questionnaires to measure pain, other symptoms, and functional limitations in neck pain disorders, both for characterizing the patient group and evaluating rehabilitation efforts. The Alfta Rehab Center developed the Profile Fitness Mapping for Neck (ProFitMap-neck) questionnaire between 1992 and 1994, which comprises two scales for assessing self-estimated symptoms and functional limitations resulting from neck problems. The symptom scale comprises two indices, representing the intensity and frequency of the symptoms, while the functional limitation scale produces a single function index. The current study describes and evaluates the reliability and validity of a Profile Fitness Mapping Neck questionnaire (ProFitMap-neck) to assess the symptoms and functional limitations of Pakistani people with chronic neck pain. There is no clear evidence that orphenadrine's antimuscarinic activity is related to its antinociceptive action, although its mild antihistaminic activity may play a role. Histamine can stimulate nociceptors, and histamine receptors are found in brain tissue and primary afferent neurons. Unlike the other muscle relaxants, orphenadrine produces some independent analgesic effects that may contribute to its efficacy in relieving painful skeletal muscle spasm. Paracetamol/acetaminophen is one of the most popular and commonly used analgesic and antipyretic drugs in the world, available without a prescription in both mono- and multi-component preparations. Patients who cannot receive treatment from non-steroidal anti-inflammatory drugs (NSAIDs), such as those with bronchial asthma, peptic ulcer disease, hemophilia, salicylate-sensitized individuals, or pregnant or breastfeeding women, opt for this drug. The mechanism of action is complex and includes the effects of both the peripheral (COX inhibition) and central (COX, serotonergic descending neuronal pathway, L-arginine/NO pathway, cannabinoid system) antinociception processes, as well as redox mechanisms that block the production of chemicals in the body that are responsible for pain. Paracetamol is a well-tolerated drug and produces few side effects from the gastrointestinal tract. The non-clinical data demonstrated that orphenadrine is a mild antinociceptive agent similar to non-opioid analgesics. There are clear indications that the combination with Paracetamol may provide increased antinociceptive activity and duration of action over and above Orphenadrine or Paracetamol alone.

GroupInterventionDescription
Patients of either sex between the ages 18 and 70 years, suffering from Chronic neck painNuberol ForteEach patient will begin with the start of physical therapy with Nuberol Forte for the symptomatic management of the chronic neck pain. Subjects will be observed for overall safety and effectiveness of study drug from visit 1 (baseline visit, screening and start of treatment), to visit 2 (Week 1-2, end of treatment) in the routine practice.
Primary Outcome Measures
NameTimeMethod
To assess the improvement in the symptoms and functional limitations of chronic neck pain by physical therapy along with Nuberol Fort (paracetamol orphenadrine combination).From baseline to week 2

The questionnaire Profile Fitness Mapping for neck (ProFitMap-neck) consists of two scales designed for the assessment of self-estimated symptoms and functional limitations due to neck problems. The symptom scale consists of two indices of separate aspects of symptomatology, the intensity and the frequency of the symptoms, and the functional limitation scale yields one function index. The calculated score for very often from 1-6, 1 score never (minimum) and 6 score often (maximum). The score 7-12 for how much, 7 score nothing (Better) and 12 score unbearable (Worst)

To assess the change of improvement in pain intensity, the pain intensity assesses by NRS scale.From baseline to week 2

Pain intensity assess by Numeric Pain Rating Scale (NRS). The pain score 0, no pain (Minimum) and 10, severe pain (Maximum).

0 (no pain), 1-3 (Mild Pain), 3-7 (moderate Pain), 7-10 (severe pain), 10 \& above (worst Pain)

Secondary Outcome Measures
NameTimeMethod
To assess The overall safety of Paracetamol orphenadrine combination in chronic neck pain.From baseline to week 2

Safety of Nuberol Forte (Paracetamol Orphenadrine combination) will assess based on the incidence of reported TEAEs by system organ class ; preferred term, as well as by categories: TEAE, severe TEAE, serious TEAE, drug-related TEAE, drug-related severe TEAE, drug-related serious TEAE, TEAE leading to discontinuation, ; TEAE with outcome of death. Drug-related TEAEs were defined as TEAEs assigned a Study Drug (Nuberol Forte) relationship of adverse reaction; suspected adverse reaction. TEAEs were coded using the Medical Dictionary for Regulatory Activities, version 19.0. The severity of TEAEs are graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03. TEAEs were defined as any adverse event that started or increased in severity after the first dose of Study Drug on Day 1 through the Final Study Visit (2 weeks +/-3 days after last dose).
