About this study

This is an open-label (all people know the identity of the intervention), non-randomized, multi-center (when more than one hospital or medical school team work on a medical research study) and prospective (study following participants forward in time) study of tramadol hydrochloride-paracetamol tablets. Participants will receive 1 to 2 tablets of tramadol hydrochloride-paracetamol orally once daily (each tablet containing tramadol 37.5 milligram [mg] and paracetamol 325mg). Participants may be given the additional dose according to the clinical requirement. The total treatment duration will be 6 hours. The total study duration will be 4 months. Efficacy will be evaluated primarily by pain intensity and pain relief. Participants will evaluate the pain severity and pain relief at 0.5, 1, 2, 3, 4 and 6 hours respectively after the first dose; and the drug efficacy and overall satisfaction level at the end of 6 hours after the first dose. Participants' safety will be monitored throughout the study.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

  • Pain intensity to be assessed using Numerical Rating Scale (NRS), NRS score more than or equal to 4 (from 0 to 10, 0 = no pain, 10 = extreme pain)
  • During normal pain and stable feeling, can study pain assessment methods and can fill in pain control diary
  • Be willing to participate in the study and must give written informed consent

Exclusion criteria

  • Have used strong opium kind of medication 7 days prior to the enrolment
  • Have severe mental disease or using antipsychotic (agent that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect) medication for medical treatment
  • Drug abuse/dependence, or chronic alcohol abuse/depend on history

Treatment and study plan

Tramadol HCl-Paracetamol

Drug

Participants will receive 1 to 2 tablets of tramadol HCl-paracetamol orally once daily (each tablet containing tramadol 37.5 milligram [mg] and paracetamol 325mg) for up to a total duration of 6 hours. Additional dose may be given based upon the clinical requirement.

Primary outcomes

  1. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 0.5

    Time frame: Hour 0.5

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  2. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 1

    Time frame: Hour 1

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  3. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 2

    Time frame: Hour 2

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  4. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 3

    Time frame: Hour 3

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  5. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 4

    Time frame: Hour 4

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  6. Pain Intensity Score Based on Numeric Rating Scale (NRS) at Hour 6

    Time frame: Hour 6

    Pain intensity was measured using NRS (0=painless and 10=most severe pain). Score of 1-3 means mild pain; 4-6 means moderate pain and 7-10 means severe pain.

  7. Number of Participants With Pain Relief Score at Hour 0.5

    Time frame: Hour 0.5

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

  8. Number of Participants With Pain Relief Score at Hour 1

    Time frame: Hour 1

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

  9. Number of Participants With Pain Relief Score at Hour 2

    Time frame: Hour 2

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

  10. Number of Participants With Pain Relief Score at Hour 3

    Time frame: Hour 3

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

  11. Number of Participants With Pain Relief Score at Hour 4

    Time frame: Hour 4

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

  12. Number of Participants With Pain Relief Score at Hour 6

    Time frame: Hour 6

    Pain relief was measured using 6-point Likert Scale (4=complete, 3=significant/comparatively large, 2=moderate, 1=mild/slight, 0=none, -1=exacerbated/heavier).

Secondary outcomes

  1. Number of Participants Who Required Additional Dosage Administration

    Time frame: Baseline up to Hour 2

    Number of participants who additionally required a second tablet within 2 hours after the first administration of the investigational drug was reported.

  2. Number of Participants With Analgesic Satisfaction Score

    Time frame: Hour 6

    Participants evaluated their satisfaction with the analgesic effect of the study drug using a 4-point scale (4=very good, 3=good, 2=average, 1=poor). Number of participants in each category was reported.

  3. Number of Participants With Overall Analgesic Satisfaction Score

    Time frame: Hour 6

    Participants and physicians separately evaluated their satisfaction with the analgesic effect of the study drug using a 5-point scale (1=very unsatisfied, 2 =unsatisfied, 3=average, 4= satisfied and 5=very satisfied). Number of participants in each category was reported.
