Study type | Interventional |
Neospastil (ketorolac tromethamine / pitofenone hydrochloride / fenpiverinium bromide fixed-dose combination) in a form of solution for injections and film-coated tablets has been studied as a treatment for pain after surgical abdominal and pelvic operations. The aim of the study was to test the hypothesis that Neospastil was non-inferior (phase II) and superior (phase III) than ketorolac tromethamine monotherapy due to the additional relaxing effect of pitofenone and fenpiverinium on the smooth muscles of internal organs. The study also aimed to show that Neospastil is safe and well-tolerated in people who have pain after surgical abdominal and pelvic operations. Study treatment was initiated with parenteral form of study drug (first 24 hours) and then switched to oral formulation. This trial was conducted in accordance with the ethical principles of Good Clinical Practice and International Council for Harmonization (ICH) Harmonized Tripartite Guidelines.

The estimated need to use the first dose of the IMP no later than 8 hours after the completion of minimally invasive surgical abdominal and pelvic operations. 3. Immediately before randomization, there is a moderate to severe pain associated with minimally invasive surgical abdominal and pelvic operation (the overall assessment of pain at rest is 4-8 points inclusively in 11-point NRS). 4.

The patient agrees to participate in the clinical trial and fulfill all the requirements of the trial and has signed the informed consent form. 7. According to the investigator, IMP is an adequate tactic for postoperative analgesia. Exclusion Criteria: 1. Hypersensitivity or allergic reactions/conditions associated with ketorolac, pitofenone, fenpiverinium, any other components of IMPs, acetylsalicylic acid or other non-steroidal anti-inflammatory drugs. 2. The patient has another disease/condition that requires constant use of non-topical analgesics and/or anti-inflammatory agents or, in the opinion of the investigator, disturbs the patient's perception of postoperative pain. 3. The need for postoperative treatment in the intensive care unit for any reason. 4. Active peptic ulcer, recent gastrointestinal bleeding or perforation, history of peptic ulcer or gastrointestinal bleeding. 5. History of bronchial asthma. 6. Severe heart failure (class III-IV according to NYHA). 7. Severe liver failure (including an increase in the activity of alanine aminotransferase and/or aspartate aminotransferase in the blood more than three times the upper limit of normal). 8. Moderate to severe renal failure (blood creatinine concentration > 160 µmol/l). 9. Suspected or confirmed cerebrovascular bleeding, hemorrhagic diathesis, including blood coagulation disorders and high risk of bleeding. 10. Dehydration with the risk of kidney failure due to a decrease in the volume of circulating blood. 11. Benign prostatic hyperplasia of the ?? and ??? degree. 12. Cardiovascular diseases in which an increase in heart rate may be undesirable (for example, atrial fibrillation, tachycardia [pulse rate at rest > 100 bpm], severe arterial hypertension), as well as an artificial pacemaker. 13. Glaucoma. 14. Signs of intestinal obstruction and/or history of megacolon. 15. Anemia (hemoglobin concentration < 90 g/l) and/or leukopenia (leukocyte count < 3.2x109/l) according to the results of preoperative laboratory examination. 16. Diseases or conditions that make it impossible to take drugs orally in accordance with the Clinical Trial Protocol and/or disrupt their absorption in the gastrointestinal tract. 17. The use of drugs prohibited by the Clinical Trial Protocol before the start of study treatment and/or the need to use drugs prohibited by the Clinical Trial Protocol during the investigational treatment. 18. Mental disorder/illness, which, in the opinion of the investigator, may prevent the patient from fulfilling all the requirements of the trial. 19. Pregnancy or lactation. 20. Within 30 days prior to randomization, the use of a drug or medical product in another clinical trial. 21. The patient has already been previously randomized in this trial. Criteria to start the 2nd stage of treatment, the patient had to meet the criteria for switching to IMP for oral administration: - pain level of 4-6 points at movements according to the 11-point Numerical Rating Scale (NRS) (7 points were allowed, if pain level at rest did not exceed 6 points according to 11-point NRS); - no more than 12 hours have passed since the last use of IMP; - oral analgesic use is an adequate tactic for postoperative analgesia. |
