Acute Musculoskeletal Spasm Due to Low Back Pain
Drug: Eperisone hydrochloride and Diclofenac sodium
Drug: Eperisone hydrochloride
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: Evaluation of Efficacy and Tolerability of a Fixed Dose Combination of Eperisone Hydrochloride and Diclofenac Sodium in the Treatment of Acute Musculoskeletal Spasm Associated With Low Back Pain: An Observer Blind, Prospective, Randomized, Controlled Study

Primary Outcome Measures:
  • Finger to Floor Distance: Improvement in Finger to Floor Distance compared to baseline. [ Time Frame: Day 1,3,7 and 10 of study period ]
    Improvement in the Fingertip-to-Floor-surface Distance [FFD] from baseline on Day 3, Day 7 & Day 10. Finger Floor Distance [FFD] is an index for the mobility of the lumbar spinal cord and is measured as the distance between the finger-tip of the middle Finger to the Floor-surface as determined while standing with the spinal cord flexed with complete extension of knee joint. It is measured in millimeters.

Secondary Outcome Measures:
  • Objective Efficacy Assessment: Improvement in Lasegue's sign compared to baseline [ Time Frame: Day 1, 3, 7 and 10 of study period ]
    Lasegue's sign is the lumbar pain [or exacerbation of existing pain] experienced by the patient on passive movement of the legs during flexion of hip joint i.e. passive straight leg raising. It is assessed as either 'Positive' or 'Negative' sign.

  • Subjective Efficacy Assessment: Improvement of lumbar cinesalgia compared to baseline [ Time Frame: Day 1, 3, 7 and 10 of study period ]
    Improvement in Lumbar Cinesalgia (pain in lumbar region) assessed on a 0 to 100mm Visual Analogue Scale (VAS) with '0' representing 'NO PAIN' and 100 representing 'SEVERE INTOLERABLE PAIN'

Study Completion Date: September 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: Eperisone hydrochloride and Diclofenac sodium
Fixed dose capsule formulation of eperisone hydrochloride 50 mg plus diclofenac sodium 50 mg to be given 3 times a day after meals for 7 to 10 days
Active Comparator: 2 Drug: Eperisone hydrochloride
eperisone hydrochloride 50 mg as tablet formulation to be given 3 times daily after meals for 7 to 10 days

Detailed Description:
This study is an observer-blind, prospective randomized, controlled study to evaluate efficacy and safety of fixed dose combination of eperisone hydrochloride 50 mg and diclofenac sodium 50 mg three times daily with plain eperisone hydrochloride 50 mg three times daily in patients with musculoskeletal spasm associated with low back pain. A total of 240 adult patients of either sex, 120 patients in each arm, who fulfill the inclusion and exclusion criteria will be included in this study. The patients will be evaluated at Days 3, 7 and 10 of the study visit for efficacy and safety. The efficacy evaluation includes objective parameters like Finger-to-Floor distance, Lasegue's sign, tenderness of par vertebral muscles, lumbar and dorsal hypermyotonia, leg tendon reflexes, need for rescue medication and subjective parameters like improvement in lumbar cinesalgia, pain in lower extremities, sensory disturbances of lower limb, and Global Assessment of Response to Therapy (PGART). Patients will be evaluated for safety on the clinical adverse events reported during the study period, sedation on drowsy alert scale and Global Assessment of Tolerability to Therapy (PGATT). The patients will also be evaluated for laboratory safety as assessed by measuring laboratory parameters for hemogram, renal and hepatic parameters.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  3. Muscle Sprains with spasms

    • Patients willing to take the medications as directed and willing to come for the follow-ups
    • Willing to comply with the protocol requirements
    • Willing to give the written informed consent

Exclusion Criteria:

  • Patients associated with other lumbar spinal tract conditions such as spondylitis, fracture, cancers, severe arthritis and osteoporosis.
  • Muscular diseases such as myositis, poliomyelitis, muscular dystrophy and myotonia.
  • Other known systemic diseases affecting the neurological or endocrine.

  • Patients who had taken any form of skeletal muscle relaxant in the previous 7 days.
  • Pregnant / Lactating woman or women of child bearing potential not following adequate contraceptive measures.
  • Patients with known hypersensitivity to ingredients of study/active comparators.

  • Patients in whom acetylsalicylic acid (ASA) or other non-steroidal anti-inflammatory agents (NSAIDs) have induced asthma, rhinitis, urticaria or other allergic manifestations.
  • Any other condition that, in the opinion of the investigator, does not justify the inclusion of the subject in the study.
