For epilepsy

Historically the only melanocortin peptide to be used clinically is the parent hormone from which all these peptides are derived from namely ACTH (see above). It has also been used in the treatment infantile spasms for epilepsy, where it is administered as an intramuscular injection only over a 2-12 weeks period. Obvious side effects include weight gain, puffy face, high blood pressure and an increased risk of infection and should never be administered to patients with diabetics, renal or heart failure. ACTH is also used as a stimulation test to measure adrenal cortex activity, i.e. production of cortisol and is used to ascertain whether someone has Addison s disease. 

This is not really a treatment but there is a view that glial cells can protect against seizures since the enzyme systems they possess (e.g. Na-K+ATPase and carbonic anhydrase) facilitate the regulation of ion movements and reduce the spread of seizures. Certainly ageing, a fatty diet, and phenytoin itself increase glial cell count while decreasing seizure susceptibility. In fact inhibition of carbonic anhydrase and the production of bicarbonate was one of the first treatments for epilepsy and a recent discovery that under certain circumstances intracellular bicarbonate can depolarise neurons has created a fresh interest in it.

Mesial temporal lobe epilepsy (MTLE) A type of epilepsy that consists of partial seizures arising from the mesial temporal lobe of the brain. Often this type of epilepsy is associated with an anatomic change described as hippocampal sclerosis. Patients with this type of epilepsy often have excellent outcomes with surgery for epilepsy.

The extensive clinical experience with these drugs in epilepsy shows they are better tolerated and less toxic than lithium (Bowden and Muller-Oerlinghausen, 2000 Rang et ah, 2003). Since the dose regimens for epilepsy and affective disorders are similar, it would be expected that the levels of adverse drug reactions would also be similar. With... 

Long before the age of plastics and nylons, I. G. Farben-industrie was known to many Americans as simply the world s best druggist. Every reputable pharmacy, every physician s bag, every good family medicine cabinet, stocks some of Farben s 6000 medicines. The firm invented a drug that is still the best cure for epilepsy. They made atabrine, the quinine-substitute for treating malaria. And from the aspirin tablet alone, I. G. Farben made a vast fortune. 

PET scans with 18F-fluorodeoxyglucose (18F-FDG) have an established role in the localization of epileptic foci in patients being evaluated for epilepsy surgery. 

There are currently no diagnostic laboratory tests for epilepsy. In some cases, particularly following GTC (or perhaps CP) seizures, serum prolactin levels may be transiently elevated. Laboratory tests may be done to rule out treatable causes of seizures (e.g., hypoglycemia, altered serum electrolyte concentrations, infections, etc.) that do not represent epilepsy.

In contrast to the reduction of tremors by DFMO, pretreatment of rats with diphenylhydantoin results in exacerbation of chlordecone-induced tremors (Hong et al. 1986 Tilson et al. 1985, 1986b). The mechanism for the exacerbation of the tremors is unknown. Therefore, if persons receiving diphenylhydantoin treatment for epilepsy were exposed to sufficiently high concentrations of chlordecone at a hazardous waste site, increased tremor severity would be likely to occur. 

The use of valerian extends back at least 1000 years, and it gained a reputation in sixteenth-century Europe as a treatment for epilepsy (Tyler 1994 Temkin 1971). Its reported uses are broad (digestive aid, muscle relaxant, antipyretic, etc.) but it is commonly known to treat insomnia and anxiety (Gruenwald et al. 1998 Kowalchick and Hylton 1987). Valerian has a distinct, unpleasant odor. Perhaps appropriately, it is believed to be an herb in the writings of Galen and Dioscorides, called phu (Leyel 1994). 

Benzodiazepines. Safer than the barbiturates but acting in a similar manner, the benzodiazepines have largely replaced barbiturates since their introduction in the 1960s. Other uses of benzodiazepines include treatment for epilepsy, alcohol withdrawal, several anxiety disorders, agitation, and impulsivity, as muscle relaxants, and as conscious sedation during certain medical procedures. 

Clinically, it was found that for epilepsy patients, the optimal dose for adults is 1.6-2 g/day for children it is 1-1.5 g/day. Under this dosage complete disappearance of epileptic seizures is noted in over 20 per cent of cases [619,625].

Valproic acid, like the succinimides, is nsed for epilepsy in the absence of attacks, but its clinical efficacy exceeds that of the succinimides. 

Benzodiazepines are primarily used in medicine as tranquilizers. However, they also have been snccessfully used for epilepsy in controlling long-lasting convnlsions. The most widely nsed is diazepam (5.1.2) and chlordiazepoxide (5.1.22). The synthesis of these was described in Chapter 5. 

The third drug of the benzodiazepine family used for epilepsy is called clonazepam. 

Acetazolamide is used for epilepsy in the absence of attacks and also in conjunction with other antiepileptic drugs. The most common synonym of this drag is diamox.

A reduced response to simvastatin was noted after phenytoin was added for epilepsy the cholesterol level increased from 9.4 mmol/1 to 15.99 mmol/1. The level decreased again when phenytoin was discontinued. Phenytoin induces the CYP3A4 isoform which is involved in simvastatin metabolism. Some other examples of this type of interaction are shown in Table 5.

The first effective treatment of seizure disorders was the serendipitous finding in 1857 that potassium bromide could control seizures in some patients. Even though side effects were troublesome, the bromides were widely used for many years. Phenobarbital was introduced as a treatment for epilepsy in 1912 and was immediately shown to be markedly superior to bromides. While other barbiturates were synthesized and used, none were shown to be superior to phenobarbital, and the latter compound is still used. A chemically related... 

Lamotrigine is an anticonvulsant drug that attenuates some forms of cortical glutamate release via inhibition of sodium, calcium, and potassium channels. An open-label case series (Uvebrant and Bauziene, 1994) and a case report (Davanzo and King, 1996) described improvement in autistic symptoms and self-injurious behavior, irritability, disturbed sleep, and social impairment in autistic children and an 18-year-old female with profound mental retardation, respectively, who were treated for epilepsy.
