There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Background: The aim of this prospective, randomized, double-blind study is to determine the most effective supplemental analgesic, paracetamol or lornoxicam for postoperative pain relief after lower abdominal surgery. Methods: Sixty patients scheduled for lower abdominal surgery under general anesthesia were randomly allocated to receive either isotonic saline (Control group), intravenous paracetamol 1 g every 6 h (Paracetamol group) or lornoxicam 16 mg then 8 mg after 12 h (Lornoxicam group). Additionally pain was treated postoperatively using morphine patient-controlled analgesia. Postoperative pain scores measured by the verbal pain score (VPS), morphine consumption and the incidence of side effects were measured at 1, 2, 4, 8, 12 and 24 hours postoperatively.
The aim of this study is to determine if by providing a collaborative, integrated pathway-based healthcare compared to the usual healthcare, whether or not this would be superior in reducing the length of hospital stay across five high frequency /high risk medical diagnoses: Acute Venous Thromboembolism, Acute Kidney Injury, Community Acquired Pneumonia, Adult Left Ventricular Heart Failure, and Asthma.
The investigators postulate that the use of pre-incisional peritonsillar infiltration of tramadol or lidocaine reduces both the inflammatory response and postoperative analgesic consumption, without harmful effects. Therefore, the present study is designed to evaluate the effects of infiltration of tramadol or lidocaine on the postoperative acute-phase serum protein, C-reactive protein, and analgesic consumption after tonsillectomy.
The primary objective of this Non- Interventional Study (NIS) is to describe the use of atypical antipsychotics in subjects with Schizophrenia during the hospitalisation due to acute psychotic episode by evaluation of drug, dose and mode of administration of the medication.
This is a randomized phase III trial of CC-5013 (lenalidomide, NSC-703813) and low dose dexamethasone (LLD) versus bortezomib (PS-341, NSC-681239), lenalidomide and low dose dexamethasone (BLLD) for induction, in patients with previously untreated multiple myeloma without an intent for immediate autologous stem cell transplant.
This is a Randomized Multicentre study Comparing GCSF Mobilized Peripheral Blood and GCSF stimulated Bone Marrow in Patients undergoing matched sibling Transplantation for Haematologic Malignancies.
The purpose of this study is to compare the antitumor activity of everolimus plus best supportive care versus placebo plus best supportive care in patients with progressive nonfunctional neuroendocrine tumor (NET) of gastrointestinal (GI) or lung origin without a history of, or current symptoms of carcinoid syndrome.
Asthma is the most common chronic illness of childhood. About 10% of children are affected. Not surprisingly, acute asthma exacerbations are one of the common reasons to visit pediatric emergency rooms (ER). About 5.7% of all pediatric emergency room visits are due to acute asthma exacerbation. Around 8% of those get admitted to the hospital. This constitutes huge financial and administrative burden on the health care system. Inhaled corticosteroids (ICS) is the gold standard prophylactic therapy for patients with persistent asthma. In the setting of acute asthma exacerbation systemic steroids given early in the course of treatment help decrease the rate of admission and return to the ER. However, the anti-inflammatory action of corticosteroids, through which this effect is caused, takes 4 hours to start working. This is because it is mediated through genomic pathways where the transcription of several inflammatory cytokines is suppressed. It was also shown that corticosteroids can cause vasoconstriction through non-genomic pathways. The onset of this action is as quick as 30-60 minutes. It is proposed that this action is mediated by blocking the extraneuronal uptake (metabolism) of norepinephrine in vascular smooth muscle cells, hence, making it available for re-use by the sympathetic neuronal cells. Our objective is to compare the efficacy of adding repetitive sequential doses of budesonide versus placebo (normal saline (NS)) to β2-agonist and ipratropium bromide (IB) combination (standard treatment) in the management of acute asthma in children in the ER. We hypothesize that the addition of budesonide to β2-agonist and IB in the management of moderate to severe acute asthma in the ER is superior to the addition of placebo.
The total effect of a medication is the sum of its drug effect, placebo effect (meaning response of placebo), and their interaction. Current interpretation of clinical trials (the gold standard of evidence-based-medicine) assumes no interaction, and the mechanism(s) underlying such interaction have not been fully explored. One possibility is that the placebo effect may modulate drug bioavailability. Using caffeine as a model drug, we have recently shown that the placebo effect of caffeine ingestion prolongs caffeine half life. Due to the novelty of this finding and its important clinical practice and clinical research implications, it needs to be confirmed in another set of subjects and extended to additional drugs. The results of the study are expected to further our understanding of the mechanism of action of a widely used medical intervention, i.e., placebo. The results will be important for both clinical practice and clinical research.
The total effect of a medication is the sum of its drug effect, placebo effect (meaning response of placebo), and their possible interaction. Current interpretation of the results of clinical trials (the gold standard in evidence based medicine) assumes no such interaction. Using a novel cross-over balanced placebo design and caffeine as a model drug, the investigators have recently shown that a negative interaction does exist; suggesting that the size of drug effect as currently measured by clinical trials may not be accurate. Due to the novelty of the findings and their important clinical practice and research implications, they need to be confirmed using another drug; and the size of drug effect measured using the novel design need to be directly compared to that measured using conventional clinical trial design. The results of the study are expected to further our understanding of a widely used medical intervention, i.e., placebo, and help assess the appropriateness of randomized clinical trials in determining the size of drug effect.
