Pharmacokinetics

ExcerptReferenceRelevance
" Following the first dose of tirilazad, dose-corrected pharmacokinetic parameters for all 3 compounds did not differ significantly among dose groups."( Pharmacokinetics of tirilazad in healthy male subjects at doses above 6 mg/kg/day.
Fleishaker, JC; Peters, GR, 1997)		0.3
" Sufficient data were available to calculate pharmacokinetic parameters for day 5 in 26 patients; 11 received no anticonvulsants."( Pharmacokinetics of tirilazad and U-89678, an active, reduced metabolite, following acute head trauma in adults.
Cross, CJ; Fleishaker, JC; Straw, RN, 1997)		0.3

Dosage Studied

ExcerptRelevanceReference
"Multiple dose pharmacokinetics and tolerability of tirilazad mesylate were assessed at the maximum dosage and duration expected for tirilazad mesylate therapy of subarachnoid hemorrhage and head injury."( Multiple-dose tolerability and pharmacokinetics of tirilazad mesylate at doses of up to 10 mg/kg/day administered over 5-10 days in healthy volunteers.
Fleishaker, JC; Hulst, LK; Peters, GR, 1994)		0.29
" The results of this study thus suggest that increased monitoring and or a reduction in tirilazad dosing may be necessary in patients with hepatic impairment."( Comparison of the pharmacokinetics of tirilazad mesylate in healthy volunteers and stable subjects with mild liver cirrhosis.

Phenobarbital: A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.. phenobarbital : A member of the class of barbiturates, the structure of which is that of barbituric acid substituted at C-5 by ethyl and phenyl groups.		3.3711barbituratesanticonvulsant;

Craniocerebral Injuries
[description not available]		02.3920
Hemorrhage, Subarachnoid
[description not available]		02.3920
Craniocerebral Trauma
Traumatic injuries involving the cranium and intracranial structures (i.e., BRAIN; CRANIAL NERVES; MENINGES; and other structures). Injuries may be classified by whether or not the skull is penetrated (i.e., penetrating vs. nonpenetrating) or whether there is an associated hemorrhage.		02.3920
Subarachnoid Hemorrhage
Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.		02.3920
Cirrhosis, Liver
[description not available]		01.9910
Liver Cirrhosis
Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules.		01.9910
Cerebral Ischemia
[description not available]		03.3711
Brain Ischemia
Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.		03.3711
Ataxia
Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.		03.3811
