Diazepam Status Epilepticus

Diazepam Status Epilepticus

Levetiracetam is a new pyrrolidine-based anticonvulsant that has fluvoximine diazepam been tried as an adjunct antiepileptic drug for dogs.
In foals, phenobarbital may be started as a followup to diazepam, with 20 mg/kg administered IV over 20 min, and then maintained at a dosage of 9 mg/kg, bid or tid. SC or IM injections are seldom used because of the variability in drug absorption.

The oral route is preferred for longterm maintenance therapy, although absorption may be limited or variable depending on the drug used (Table: Anticonvulsant Drugs).

Side effects http://freenetmap.net/4312645.php consist of sedation only, but periodic hematologic monitoring is advised because blood dyscrasias and hepatoxicity are reported in humans. In dogs, it is used as a followup to diazepam in status epilepticus by an IV infusion (3-10 mg/hr to effect) or a slow IV bolus (2-4 mg/kg every 20-30 min up to a total of 20 mg/kg).
ALT, serum alkaline phosphatase, or bile acids should be monitored.
. Therapeutic concentrations are 15-45 µg/mL.
Phenothiazine tranquilizers should be avoided in epileptic treatment in all species http://thenetdirect.com/9553455.php because they lower the seizure threshold. Bromide intoxication should be treated with an IV infusion of normal saline to promote renal excretion. In dogs, it is metabolized 30% in the liver; the remainder is excreted by the kidneys. If control is unsatisfactory, the dose should be increased over multiple steps before adding or switching to a new drug. However, one case report described adequate seizure control despite undetectable drug concentrations in plasma, possibly due to either an active metabolite or to a highly sensitive drug reaction. Accordingly, plasma concentrations declined rapidly in dogs on a 1-wk regimen of 30 mg/kg, tid. In these species, it is administered at 2-15 mg/kg to effect for anesthesia. Cats not only have a slower elimination rate than dogs but also do not develop a tolerance to the anticonvulsant effects. It has been used as effective monotherapy in humans.

In foals, as an alternative to diazepam and phenobarbital, it may be given at 2-4 mg/kg, IV to effect for controlling convulsions; sedation is likely at these dosages. http://yourglobaltrade.com/05-26-07-808.php Diazepam is generally continued as maintenance treatment in cats, with dosages ranging from 0. Phenobarbital has also been used to treat episodic dyscontrol syndrome (rage) in dogs when seizure activity is demonstrable (1. It has been used as the first and sole drug treatment for epilepsy in dogs at dosages of 50-80 mg/kg/day, divided for bid treatment. 5 mg/kg/day, or it may be used alone at 0.

For dogs, an initial IV bolus of diazepam (0. It restricts the propagation and spread of seizures and suppresses epileptogenic focus activity. If foals become highly sedated, the dose of phenobarbital should be reduced. Phenobarbital is a second drug of choice for maintenance, given at 3-6 mg/kg, divided into 2-3 daily doses. For longterm maintenance in cats and dogs, phenobarbital may be given at 2-4 mg/kg/day, PO, divided in 2, sometimes 3, daily doses. Mephenytoin, although related to phenytoin, has been effective in dogs (10 mg/kg, tid) due to a slower rate of elimination.

Clonazepam, unlike diazepam, can be used in dogs for oral maintenance therapy because diazepam brand names anticonvulsant tolerance develops less rapidly, the saturatability of its metabolism reduces the elimination rate at therapeutic concentrations, and it is more highly absorbed orally (particularly in micronized formulations). Bromide should not be used in dogs with renal dysfunction; if azotemia is present, the initial dose should be reduced by half, and serum concentrations monitored.
