Levetiracetam, sold under the brand name Keppra among others, is a novel antiepileptic drug [7] used to treat epilepsy. [8] It is used for partial-onset , myoclonic , or tonic–clonic seizures, [ 7 ] and is taken either by mouth as an immediate or extended release formulation or by injection into a vein .
The dosing range for this drug is anywhere from 100-400 mg with a half-life of 55 hours. There have been at least three separate clinical trials involving cenobamate with results showing a reduction in seizure burden by at least 50% in the experimental groups, especially at higher doses of the drug.
Seletracetam (UCB 44212) is a pyrrolidone-derived [2] drug of the racetam family that is structurally related to levetiracetam (trade name Keppra). [2] [3] It was under development by UCB Pharmaceuticals as a more potent and effective anticonvulsant drug to replace levetiracetam but its development has been halted.
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
The U.S. Food and Drug Administration (FDA) announced a new definition of “healthy” food for the first time in 30 years. The new definition will apply to manufacturers who want to call their ...
The plasma half-life is about 35 to 40 hours when carbamazepine is given as single dose, but it is a strong inducer of liver enzymes, and the plasma half-life shortens to about 12 to 17 hours when it is given repeatedly. The half-life can be further shortened to 9–10 hours by other enzyme inducers such as phenytoin or phenobarbital. About 70% ...
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
In very large overdoses, multi-dose activated charcoal is a mainstay of treatment as the drug undergoes enterohepatic recirculation. Urine alkalization (achieved with sodium bicarbonate) enhances renal excretion. Hemodialysis is effective in removing phenobarbital from the body and may reduce its half-life by up to 90%. [40]
