C.; Driessen, B. published an article.Safety of N-(2-Bromo-6-fluorophenyl)-4,5-dihydro-1H-imidazol-2-amine hydrochloride The title of the article was Pharmacokinetic profile and pharmacodynamic effects of romifidine hydrochloride in the horse. And the article contained the following:
Romifidine HCl (romifidine) is an α2-agonist commonly used in horses. This study was undertaken to investigate the pharmacokinetics (PK) of romifidine following i.v. (i.v.) administration and describe the relationship between PK parameters and simultaneously recorded pharmacodynamic (PD) parameters. Romifidine (80 μg/kg) was administered by i.v. infusion over 2 min to six adult Thoroughbred horses, and plasma samples were collected and analyzed using liquid chromatog.-mass spectrometry. Limit of quantification was <0.1 ng/mL. PD parameters and arterial blood gases were measured for 300 min following romifidine administration. Statistical PD data anal. included mixed-effect modeling. After i.v. administration of romifidine, the plasma concentration-vs.-time curve was best described by a two-compartmental model. Terminal elimination half-life (t1/2β) was 138.2 (104.6-171.0) min and volumes for central (Vc) and peripheral (V2) compartments were 1.89 (0.93-2.39) and 2.57 (1.71-4.19) L/kg, resp. Maximum plasma concentration (Cmax) was 51.9 ± 13.1 ng/mL measured at 4 min following commencement of drug administration. Systemic clearance (Cl) was 32.4 (25.5-38.4) mL·min/kg. Romifidine caused a significant reduction in heart rate and cardiac index and an increase in mean arterial pressure (P < 0.05). Sedation score and head height values were significantly different from the baseline values for 120 min (P < 0.05). The decline in cardiovascular and sedative effects correlated with the decline in plasma romifidine concentration (P < 0.05). In conclusion, a highly sensitive anal. technique for the detection of romifidine in equine plasma allowed detailed description of its PK profile. The drug produces long-lasting sedation in horses that corresponds with the long terminal elimination half-life of the drug. The experimental process involved the reaction of N-(2-Bromo-6-fluorophenyl)-4,5-dihydro-1H-imidazol-2-amine hydrochloride(cas: 65896-14-2).Safety of N-(2-Bromo-6-fluorophenyl)-4,5-dihydro-1H-imidazol-2-amine hydrochloride
