METHODOLOGY
- Consent: Participants will be explained the benefit and harm of joining the study and the freedom of withdrawing from the study at any moment they would like to. A full voluntary written informed consent will be obtained from each participant. Study will be conducted following the principles of Helsinki after getting written permission of the institutional ethics committee. Before enrolment of first subject in this study registration for clinical trial will be done.
- Participants: Patients of either sex, above 18 yrs. of age undergoing Total Knee Arthroplasty will be the participants in this study.
1. Inclusion Criteria:
- Patients both males and females undergoing elective total knee replacement surgery
- Patients are capable to provide an informed consent
- Age 18-75 yrs.
2. Exclusion Criteria:
- Patients with Asthma, COPD or any other respiratory disease.
- Persistent nausea and vomiting at the time of randomization.
- Epilepsy.
- Treated with mono amine oxidase inhibitors, tricyclic antidepressants, serotonin norepinephrine re uptake inhibitors.
- Patients with ASA grading 3 or more.
- Drug abuse history.

- Migraine patients or patients complaining dizziness, vertigo.
Screening: The trial will be comprised of complete medical history and physical examination and screening. Pre-operative laboratory investigations will be recorded in case record form.
- Randomization: A total of 90 Participants will be selected by computer generated random list.
- Blinding: The study will be conducted in a double blinded manner.
- Treatment Administration and baseline follow up: The participants will be assigned to receive 100 mg of Tapentadol or a matched placebo orally 1 hr before spinal anesthesia in a double-blind manner. All the participants, both control and Tapentadol group will be anesthetized (SP) as per the standard protocol after similar pre-medication. Single dose of injection Paracetamol 1 gm i.v. will be provided in both the groups immediately after operation.
- Assessment of efficacy and safety and Duration: All the subjects will be assessed for pain at rest, before surgery, at 0, 6 12 &, 24 hrs. post operatively by visual analogue scale score(VAS) (0 mm: no pain,100 mm: Worst pain imaginable).16 and TOTPAR SCALE(None-Mild-Moderate-Severe) *. They also will be evaluated for nausea, vomiting, drowsiness, and pruritus and will be rated on0,6,12, & 24 hrs.16. Total rescue analgesic consumption also will be assessed at 24 hrs post operatively 16. The time of 1st request for supplemental analgesia also will be recorded. A blood sample will be obtained from each participant at 0 hrs. post operatively to measure the tapentadol concentration and Cholecystokinin by ELISA method.
