ryanodine receptor abnormalities has implicated in the generation and maintenance of seizure. dantrolene, a selective ryanodine receptor antagonist, may be a potential drug for the prevention of seizure. therefore, we aimed to clarify the protective effects of dantrolene against pentylenetetrazole seizure in mice. male albino mice were received an intra-peritoneal injection of pentylenetetrazol...
OBJECTIVE The use of dantrolene in the treatment of hyperpyrexia related to MDMA (3,4-methylenedioxymethamphetamine) is controversial, with little data available to guide clinical decision-making. Although the treatment is recommended by several poison control centres, published data are primarily in the form of case reports and animal and in vitro experiments. We conducted a systematic review ...
Dantrolene is the first line therapy of malignant hyperthermia. Animal studies suggest that dantrolene also protects against heart failure and arrhythmias caused by spontaneous Ca(2+) release. Although dantrolene inhibits Ca(2+) release from the sarcoplasmic reticulum of skeletal and cardiac muscle preparations, its mechanism of action has remained controversial, because dantrolene does not inh...

The skeletal muscle relaxant dantrolene inhibits the release of Ca from the sarcoplasmic reticulum during excitation-contraction coupling and suppresses the uncontrolled Ca release that underlies the skeletal muscle pharmacogenetic disorder malignant hyperthermia; however, the molecular mechanism by which dantrolene selectively affects skeletal muscle Ca regulation remains to be defined. Here w...
Dantrolene is effective in the management of malignant hyperpyrexia. Due to the similarities of malignant hyperpyrexia and heat stroke, we have investigated the effect of dantrolene on heat stroke in sheep. Our study indicates that dantrolene pretreatment decreases the extent of heat stroke signs and some of the induced changes in enzymes and hormones. These results indicate that dantrolene may...
Dantrolene was introduced for treatment of malignant hyperthermia. It also has antiarrhythmic properties and may thus be an alternative to amiodarone for the treatment of ventricular fibrillation (VF). Aim of this study was to compare the return of spontaneous circulation (ROSC) with dantrolene and amiodarone in a pig model of cardiac arrest. VF was induced in anesthetized pigs. After 8 min of ...
Dantrolene inhibits and ryanodine stimulates calcium release from skeletal-muscle sarcoplasmic reticulum (SR), the former by an unknown mechanism, and the latter by activating the ryanodine receptor (RyR), the primary Ca2+-release channel of SR. Dantrolene is used to treat malignant hyperthermia (MH), a genetic predisposition to excessive intracellular Ca2+ release upon exposure to volatile ana...
BACKGROUND Resistant ventricular fibrillation, refibrillation. and diminished myocardial contractility are important factors leading to poor survival after cardiac arrest. We hypothesized that dantrolene improves survival after ventricular fibrillation (VF) by rectifying the calcium dysregulation caused by VF. METHODS AND RESULTS VF was induced in 26 Yorkshire pigs for 4 minutes. Cardiopulmon...
