Blood pressure response to Ro15-1788, a benzodiazepine antagonist. 1985

H C Rosenberg, and T H Chiu

The effects of Ro15-1788, a benzodiazepine antagonist, on heart rate and blood pressure were studied in chloralose anesthetized cats. In previously untreated controls, Ro15-1788 lowered both systolic and diastolic arterial pressure about 15 mm Hg, and slightly decreased heart rate. In cats that had been given a single acute dose of diazepam or flurazepam, Ro15-1788 increased blood pressure about 40 mm Hg. A similar increase was measured in cats that were tolerant and physically dependent after 5 weeks of chronic flurazepam treatment. High spinal (C-1) section abolished all Ro15-1788 effects. It is suggested that the observed drug actions occur within the CNS rather than in the periphery, and that it might be useful to study further the cardiovascular actions of benzodiazepine agonists and antagonists.

D001794	Blood Pressure	PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.	Systolic Pressure,Diastolic Pressure,Pulse Pressure,Pressure, Blood,Pressure, Diastolic,Pressure, Pulse,Pressure, Systolic,Pressures, Systolic
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D003292	Convulsants	Substances that act in the brain stem or spinal cord to produce tonic or clonic convulsions, often by removing normal inhibitory tone. They were formerly used to stimulate respiration or as antidotes to barbiturate overdose. They are now most commonly used as experimental tools.

D003975	Diazepam	A benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant, and amnesic properties and a long duration of action. Its actions are mediated by enhancement of GAMMA-AMINOBUTYRIC ACID activity.	7-Chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one,Apaurin,Diazemuls,Faustan,Relanium,Seduxen,Sibazon,Stesolid,Valium
D004361	Drug Tolerance	Progressive diminution of the susceptibility of a human or animal to the effects of a drug, resulting from its continued administration. It should be differentiated from DRUG RESISTANCE wherein an organism, disease, or tissue fails to respond to the intended effectiveness of a chemical or drug. It should also be differentiated from MAXIMUM TOLERATED DOSE and NO-OBSERVED-ADVERSE-EFFECT LEVEL.	Drug Tolerances,Tolerance, Drug,Tolerances, Drug
D005442	Flumazenil	A potent benzodiazepine receptor antagonist. Since it reverses the sedative and other actions of benzodiazepines, it has been suggested as an antidote to benzodiazepine overdoses.	Flumazepil,Anexate,Lanexat,Ro 15-1788,Romazicon,Ro 15 1788,Ro 151788

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
