Randomized Controlled Trial Comparative Study
Pharmacokinetics and pharmacodynamics of intravenous dexmedetomidine in healthy Korean subjects.
Dexmedetomidine is a selective alpha2-adrenoreceptor agonist used for sedation in critically ill patients. The current study aimed to evaluate the pharmacokinetics (PKs), pharmacodynamics and tolerability of intravenous dexmedetomidine in healthy Korean subjects. ⋯ Dexmedetomidine shows linear PK characteristics and dose-dependent sedative effects. A two-compartment population PK model was developed for healthy Korean subjects. The PK parameter estimates are similar in Koreans and Caucasians.

Randomized Controlled Trial Comparative Study
Lack of clinically significant pharmacological interactions between ticagrelor and enoxaparin or unfractionated heparin in healthy subjects.
Patients with acute coronary syndromes (ACS) receive several pharmacological therapies concomitantly, including antiplatelet and anticoagulant agents. As unfractionated heparin (UFH) activates platelets in vitro and in vivo, co-administration with an antiplatelet agent may lead to decreased clinical effectiveness of the latter. The aim was therefore to determine any potential drug-drug interactions between the new oral antiplatelet agent ticagrelor, and UFH or enoxaparin. ⋯ Enoxaparin and UFH had no effect on the pharmacokinetics and no clinically significant effect on the pharmacodynamics of ticagrelor. Ticagrelor had no clinically significant effects on the pharmacodynamics of enoxaparin or UFH.

Spontaneous Adverse Drug Reaction Reporting Systems (ADRRS) provide early warnings or 'signals' for adverse drug reactions (ADRs). Our aim was to survey reports of ADRs made through our teaching-hospital-based pharmacovigilance system to identify the drugs most commonly associated with allergies and the types of immunological reactions reported. ⋯ A hospital-based ADR reporting system can generate useful data. In our study, antibiotics accounted for the majority of drug allergies, particularly anaphylactic reactions. More cases of drug allergies were owing to cephalosporin allergies than penicillins. Anti-epileptic agents caused most of the severe drug hypersensitivity syndromes.
