This study is to investigate whether anastrozole ODF is bioequivalent with Arimidex tablet after a single oral administration of each anastrozole formulation.
Propofol is a commonly used agent for sedation and anaesthesia in the intensive care unit and the operating room. The pharmacokinetics of propofol are difficult to predict in patients not conforming to the norms in which the original pharmacokinetic research was based. Such patients, including the critically ill, and morbidly obese, are increasingly being encountered. The investigators group have been involved in the development of a device which can measure blood propofol concentrations, and hope for this to be available to use in the operating room in a clinically useful timeframe in the future. Data will be collected on patients undergoing propofol based general anaesthesia. The Marsh target controlled algorithm in effect site mode (commonly used by anaesthetists) will be assessed for accuracy using the propofol monitor. A new proportional correction method will be developed using this data, designed to enable recalibration of the TCI algorithm in near real time in order to achieve a more accurate estimated propofol concentration in these identified patient groups. The research will investigate the effectiveness of a correction of estimated propofol levels based on a one off measurement early on in the anaesthetic, and will take subsequent samples to measure propofol levels without modifying the TCI algorithm. Additionally, data on anaesthetist choice of TCI model, and method of administration in this relatively unselected group of patients will be analysed.
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 purpose of this study is to determine the pharmacokinetics and safety of TAK-875, once daily (QD), with and without glimepiride in participants with type 2 diabetes mellitus (T2DM).
The study aims to compare blood pressure and pulse in male healthy subjects taking mirabegron and tamsulosin both alone and in combination.
The study aimed to compare age and gender differences for increasing doses of mirabegron when given to healthy young and elderly males and healthy young and elderly females.
The purpose of this study is to measure the area under the curve (AUC0-48h; extent of systemic availability) and the maxi-mum concentrations (Cmax) of total serum levothyroxine (TT4, bound and free fraction) after a single pharmacological dose of 600 μg administered as tablets also containing iodine supple-ments vs. the same dose of levothyroxine administered as a reference solution without iodine.

The primary objective of this study is to learn about the relative bioavailability (the extent to which the drug becomes available to the body) and pharmacokinetics (blood levels) of rivaroxaban in healthy participants after receiving a 20 mg rivaroxaban tablet orally as a whole tablet, crushed and mixed in applesauce, and as a suspension through a Naso-gastric (NG) tube. The relative bioavailability of rivaroxaban may be different when given as a crushed tablet compared with an intact (whole) tablet and when given via an NG tube. The safety and tolerability of rivaroxaban will also be assessed.
