Effects of Voriconazole on the Pharmacokinetics and Pharmacodynamics of Oral Buprenorphine: A Two-phase Cross-over Study in Healthy Subjects

The psychomotor effects on buprenorphine will be assessed with the measurement of pupil size, Maddox wing test and digit symbol substitution test

The analgesic effect of buprenorphine will be evaluated using the cold pressor test. Briefly, the subject's hand is immersed into ice-cold water of + 4° C up to the wrist. The subject is told to keep his or her hand in the water and to report when the cold sensation becomes painful. Cold pain threshold is defined as the latency from the immersion of the hand to the subject's first report of pain. Cold pain intensity is assessed at 30 s intervals following immersion of the hand in cold water for up to 60s . A verbal numerical rating scale of 0-100 will be used.

25 patients after elective colorectal surgery will be given 100 mg caffeine citrate orally diluted in 50 ml apple flavored water three times per day starting on the morning of postoperative day 1 after surgery until flatus will occur for the first time or to a maximal period time of 7 days, whichever comes earlier.

The time in hours from end of surgery to first flatus.

The time in hours from end of surgery to first bowel movement.

The time in hours from end of surgery to first solid meal tolerated (the first time the patient is able to eat any food requiring chewing, without vomiting or going back to liquid diet)

The postoperative hospital stay is the number of hours from surgery until discharge. The criteria for hospital discharge include stable vital signs with no febrile morbidity for ≥24 hours, passage of stool, toleration of a solid diet and the absence of other complications.

After a baseline polysomnography (PSG), subject will receive 100 mg of trazodone 30 minutes prior to their 2nd PSG and will receive 100mg Placebo 30 minutes prior to their 3rd PSG.

Sleep Disorder

BASELINE PSG Patient has to sleep over at the hospital (sleep lab). The technician will place several sensors on your scalp, temples, chest and legs to record all the data needed for your evaluation. You will be monitored throughout the duration of the test (approximately 6 hours). Brain waves, eye movements, chin muscle tone, breathing patterns, snoring, heart rate, blood pressure, blood oxygen level, body position and muscle activity will be recorded.

Accuracy and Efficacy of Trazodone (Desyrel) on Sleep Quality and Pain Management of TMD Patient

Stabilisation de la qualité du Sommeil Chez le Sujet en Douleurs Orofaciales Chroniques - étude expérimentale en chassé croisé : Trazodone/ Placebo

Based on visual analysis of these parameters:
Sleep stage shifts: change from deeper to lighter sleep stage (stage 2, 3&4, REM toward stages 1 or 2); measured as number/hour.
Awakening: presence of alpha and beta electroencephalography (EEG) activities, with rise in submental/chin muscle tone, lasting>10s; measured as number/hour.
Movement arousal: an EEG pattern or awakening associated with major body movement; measured as number/hour.
Microarousal (MA): abrupt shift in EEG frequency lasting more than 3s and less than 10, excluding spindles and K-complexes; measured as number/hour.
Heart rate rapid fluctuations: acceleration of heart beat within 15s recorded by 2 electrodes at thoracic positions. Measured as number/hour.
Presence and severity of abnormal values will be determined based on AASM recommended cutoffs. For value reference in TMD women participants, see Dubrovksy et al 2014. We hypothesize all these parameters would decrease in Trazodone group.

Based on visual analysis of these parameters:
Sleep duration: from time in bed to wake as estimated by EEG (minutes) Sleep efficiency: % time asleep/time in bed (time in minutes) Sleep fragmentation: index of all above criteria (point 1) number/hour Sleep latency: from light off to first sign of sleep on EEG (minutes). REM sleep latency: from sleep onset (on EEG) to first REM sleep stage (minutes).
Presence and severity of abnormal values will be determined based on AASM recommended cutoffs. For references of values in TMD women participants, see Dubrovksy et al 2014. We hypothesize that sleep duration and efficiency will improve in Trazodone group, while sleep fragmentation, sleep latency, and REM sleep latency will decrease.

Measured with a numerical rating scale (0 to 10) were 0 is poorest possible sleep quality and 10 is the greatest possible sleep quality

Measured with a numerical rating scale (0 to 100) were 0 is no pain and 100 is the most intense pain imaginable.
