Introduction: Motor behavior and coordination impairment are known side effects of opioid treatment, yet very few studies have investigated the effects of tramadol on motor behavior, or compared its effect with the effect of an opioid. This study investigates the effects of chronic injection of morphine and tramadol on rat motor function during infancy. Methods: Neonate rats (n=56) were randoml...

We tested the effect of tramadol on ventilatory control by quantifying its effect on the steady-state ventilatory carbon dioxide response and by locating its site of respiratory action within the ventilatory control system. We imposed square-wave changes in end-tidal carbon dioxide (approximately 1 kPa; end-tidal oxygen concentration kept constant at resting levels) in 10 healthy volunteers (si...

BACKGROUND Pain after amputation is common but difficult to treat, and few controlled treatment studies exist. METHODS In the current study, 94 treatment-naive posttraumatic limb amputees with phantom pain (intensity: mean visual analog scale score [0-100], 40 [95% confidence interval, 38-41]) were randomly assigned to receive individually titrated doses of tramadol, placebo (double-blind com...

Premature ejaculation (PE) is the most common sexual disorder. It affects 20%-30% of adult men; the aetiology of this condition has not yet been elucidated. The aim of this study is to evaluate the efficacy, safety, tolerability, undesirable effects and improved satisfaction with sexual intercourse with tramadol hydrochloride at different dosages for the treatment of PE. A total of 300 patients...

BACKGROUND AND OBJECTIVES The aim of this study was to investigate the effects of saline solution, bupivacaine, lidocaine and tramadol infiltration on wound healing in rats. METHOD Thirty-two male Wistar Albino rats were randomly separated into four groups, receiving 3 mL saline solution in control group (Group C, n=8), 3 mL of 2% lidocaine in lidocaine group (Group L, n=8), 3 mL of 0.5% bupi...

Background. Parenteral opioids, thus, are still popular for pain relief in labor in many countries throughout the world. Aim. To evaluate and compare the efficacy of intramuscular tramadol and pentazocine in the first stage of labor. Method. Sixty-five patients were divided into pentazocine group and tramadol group. Subjects received either 30 mg pentazocine or 1 mg/kg tramadol intramuscularly....

Background. The contribution of apathy, frequently recognized in individuals with neurodegenerative diseases, to chronic low back pain (LBP) remains unclear. Objectives. To investigate levels of apathy and clinical outcomes in patients with chronic LBP treated with tramadol-acetaminophen. Methods. A retrospective case-control study involving 73 patients with chronic LBP (23 male, 50 female; mea...

BACKGROUND AND OBJECTIVES A prospective, randomized, controlled, double-blind clinical trial to assess the effect of tramadol and ketamine, 50 mg, added to ropivacaine in brachial plexus anesthesia. METHODS Thirty-six ASA physical statuses I and II patients, between 18 and 60 years of age, scheduled for forearm and hand surgery under axillary brachial plexus block, were allocated to 3 groups....

T ramadol hydrochloride is a centrally acting synthetic analgesic with a dual mechanism of action. Tramadol and its Odesmethyl metabolite (M1) bind to opioid receptors, with M1 having a 200-fold higher affinity for binding to these receptors. Tramadol has also been shown to inhibit the uptake of norepinephrine and serotonin, suggesting that its antinociceptive activity is mediated by both opioi...

INTRODUCTION Various hemostatic and analgesic agents and techniques have been used to reduce intraoperative and postoperative hemorrhage and pain in tonsillectomy.Aims and objective; The current study aimed to compare the effect of using adrenaline plus tramadol and normal saline in maintaining hemostasis and control of pain in cold dissection tonsillectomy.
