Clinical Trials Related to Promethazine and Phenylephrine (Promethazine / Phenylephrine)

A Dose Ranging Effect of Preoperative Diphenhydramine on Postoperative Quality of Recovery After Ambulatory Surgery [Recruiting]
Pain after ambulatory surgery remains an unsolved problem in The United States and Europe. It is associated with delayed hospital discharge and it can result to an increased opioid consumption with adverse side effects. The concept of multimodal analgesic technique was introduced more than 15 years ago and several techniques have been studied over the years including non steroidal antiinflammatory drugs (NSAIDs), acetaminophen, gabapentoids, ketamine, local and regional anesthetic techniques. Histamine can have effects on polymodal nociceptors and C-fibers, producing pain which is further increased by neurogenically mediated release of substance P from afferent pain fibers. Several non-selective or H1

- selective histamine receptors antagonists have been demonstrated in animal models and

clinical pain. Chia et al demonstrated that preoperative promethazine had opioid sparing properties without adverse sedative effects in patients undergoing abdominal hysterectomy.

Diphenhydramine is an anti-histamine drug who has been found to be effective in reducing postoperative nausea and vomiting after ambulatory surgery but its effects on postoperative pain and other important outcomes after ambulatory surgery such as time to meet discharge criteria have not being studied.

The MQOR 40 is a validated instrument that was specifically design to evaluate patient recovery after anesthesia and surgery. This instrument can be particularly valid to examine interventions which affect different spheres of patient recovery as is the case of diphenhydramine. The objective of this study is to determine a dose response effect of preoperative diphenhydramine on postoperative quality of recovery after ambulatory surgery. The use of preoperative diphenhydramine can improve patient's quality of recovery, decrease postoperative pain, opioid consumption and opioid related side effects after ambulatory surgery.

The research question: Does a preoperative dose of diphenhydramine improve postoperative quality of recovery after ambulatory surgery? The hypothesis of this study is that preoperative diphenhydramine will improve postoperative pain, Postoperative nausea and vomiting (PONV), sleep which will translate in a better overall quality of recovery.

Morphine Versus Morphine-promethazine Combination for Acute Low Back Pain Relief in the Adult Emergency Department [Not yet recruiting]
Acute low back pain is a common cause for emergency department visits. Controversy remains regarding the optimal medication for acute low back pain relief. The investigators hypothesized that administration of pharmacological anxiolysis in addition to analgesia will improve pain relief and patient management in the emergency department.

Pharmacogenetic Factors and Side Effects of Metoclopramide and Diphenhydramine [Recruiting]

Lorazepam, Diphenhydramine Hydrochloride, and Haloperidol Gel in Patients With Nausea [Recruiting]
This randomized clinical trial studies lorazepam, diphenhydramine hydrochloride, and haloperidol gel in patients with nausea. Lorazepam, diphenhydramine hydrochloride, and haloperidol gel, when absorbed into the skin, may be an effective treatment for nausea and vomiting.

Adjunct Sedatives in Procedures Involving Endoscopic Ultrasound (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) [Recruiting]
The purpose of this study is to compare meperidine/midazolam with diphenhydramine, meperidine/midazolam with promethazine, and meperidine/midazolam with placebo as sedation methods. The investigators are interested to see whether adjunct sedatives (diphenhydramine and promethazine) will improve sedation.
