简要总结
A clinical, multicenter, randomized, parallel-group, double-blind, double-dummy, comparative study of non-inferiority.
⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil) .
详细描述
Patients aged between 16 and 35 years with indication for surgical removal of impacted lower third molar will be randomized at a 1:1 ratio to receive FDC oxycodone 5 mg/ibuprofen 400 mg from Eurofarma Laboratórios SA (experimental drug) or FDC codeine 30 mg/paracetamol 500 mg (Tylex® - Janssen-Cilag Farmacêutica Ltda.) as tablets, for up to three (03) days. Participants whose surgery lasts no more than 40 minutes (starting from the initial incision to the extraction of impacted third molar) and who experience post-surgical pain that is moderate to intense in intensity up to four (04) hours after the surgery ends will be randomized. The first administration of the study treatment will be performed at the clinical investigation site when post-surgical pain reaches moderate/intense intensity (≥ 40 mm on a 0-100 mm Visual Analogue Scale [VAS]).
Participants will be instructed to, from then on, use the study treatment as needed for pain relief, observing a minimum interval of six (06) hours between two intakes, for up to three (03) days (72 hours after the initial dose).
Subjects who meet all of the eligibility criteria will be randomized to one of the following treatment groups:
Group 1: FDC oxycodone 5 mg/ibuprofen 400 mg from Eurofarma Laboratórios SA (experimental drug) - Participants randomized to this group will receive one (01) tablet of the experimental drug + one (01) tablet of Tylex® placebo when post-surgical pain intensity reaches moderate to intense intensity (≥ 40 mm on a 0-100 mm VAS).
Group 2: Tylex® (codeine 30 mg/paracetamol 500 mg) - Participants randomized to this group will receive one (01) Tylex® tablet (codeine 30 mg/paracetamol 500 mg) + one (01) tablet of FCD placebo when post-surgical pain intensity reaches moderate to intense intensity (≥ 40 mm on a 0-100 mm VAS).

入选标准
- •Aged between 16 and 35 years old (inclusive).
- •Presence of impacted third lower molar with surgical removal indicated (diagnosed via panoramic x-ray within six [6] months before inclusion in the study), at vertical, mesioangular or horizontal position as per the Winter's classification, provided that it belongs to the following Pell & Gregory's classes.
- •Maximum surgery duration of 40 minutes, counted from the initial incision to the impacted third molar extraction.
- •Moderate to intense postoperative pain (≥ 40 mm at a VAS of 0-100 mm) up to four (4) hours after the end of the surgery (counted from the end of the suture).
- •Informed Consent Form (ICF) and Informed Assent Form (IAF) signature, when applicable, before performing any study procedure
排除标准
- •Known hypersensitivity to oxycodone or other opioid agents.
- •Known hypersensitivity to ibuprofen, acetylsalicylic acid (ASA), or any other non-steroidal anti-inflammatory drug (NSAID).
- •Known hypersensitivity to paracetamol or to any component of the Tylex® formulation;
- •History of bronchospasm or other anaphylactoid reactions (e.g.: hives, rhinitis, angioedema) associated with the use of analgesics, such as salicylates, paracetamol, diclofenac, ibuprofen, indomethacin, naproxen;
- •Abuse of illegal drugs, including alcoholism; emotional instability and/or previous attempt of suicide;
- •Pregnancy or breastfeeding.
- •Women of childbearing potential who do not agree to use a known effective birth control method, unless the participants are surgically sterile or state they are expressly free of the risk of getting pregnant for not having sexual intercourse or for having sexual intercourse with no reproductive potential.
- •Known hepatic or renal failure.
- •Participation in a clinical research protocol within the past 12 months, unless the investigator considers that the participation in the study could result in a direct benefit to the subject.
- •Presence of any condition that, in the investigator's opinion, would make the subject ineligible to participate in the study.
研究组 & 干预措施
Group 1: FDC oxycodone 5 mg/ibuprofen 400 mg from Eurofarma Laboratórios SA (experimental drug)
Participants randomized to this group will receive one (01) tablet of the experimental drug + one (01) tablet of Tylex® placebo when post-surgical pain intensity reaches moderate to intense intensity (≥ 40 mm on a 0-100 mm VAS). Participants will be instructed to, from then on, use this same treatment whenever needed for pain relief, observing a minimum interval of six (06) hours between two intakes, for up to 3 days (72 hours after the initial dose).
干预措施: FDC of oxycodone 5 mg/ibuprofen 400 mg (Drug)
Group 2: Tylex® (codeine 30 mg/paracetamol 500 mg)
Participants randomized to this group will receive one (01) Tylex® tablet (codeine 30 mg/paracetamol 500 mg) + one (01) tablet of FCD placebo when post-surgical pain intensity reaches moderate to intense intensity (≥ 40 mm on a 0-100 mm VAS). Participants will be instructed to, from then on, use this same treatment whenever needed for pain relief, observing a minimum interval of six (06) hours between two intakes, for up to 3 days (72 hours after the initial dose).
干预措施: Tylex (Drug)
结局指标
主要结局
sum of pain relief scores over 6 hours (TOTPAR6)
时间窗: 6 hours
After the administration of the first dose of study treatment, participants will assess pain relief using the 5-point categorical scale (0 = no relief, 1 = little relief, 2 = some relief, 3 = a lot of relief, 4 = complete relief) in one-hour intervals (1, 2, 3, 4, 5, and 6 h). The sum of pain relief scores within 6 hours determines TOTPAR6, which ranges from 0 to 24, and the higher the value, the greater the pain relief.
次要结局
- Sum of pain relief scores over four (4) hours (TOTPAR4)(4 hours)
