B. Evidence has been presented for an unstable aldehyde carbamate intermediate, 5-carbamoyl-5-phenylproprionaldehyde (aldehyde monocarbamate), in the pathway leading to the formation of the major metabolite in humans, 2-carbamoyl-5-phenylproprionic acid (acid monocarbamate. Although few data are available to describe the typical presentation and clinical course, available information from seven cases of likely felbamate hepatotoxicity reveals a high incidence of females (6/7) and time to presentation of 26–261 days. Hepatic function continued to decline over the ensuing 5 weeks, ultimately progressing to multisystem organ failure. Massive to submassive necrosis without signiﬁcant ﬁbrosis was observed on microscopic sections and moderate inﬂammatory inﬁltrate consisting primarily of lymphocytes was present within portal tracts.
Considerable progress has been made over the past 8 years in identifying and characterizing potential reactive metabolites that may play a role in the pathogenesis of felbamate idiosyncratic toxicities, however. Postulated Mechanisms The mechanism of felbamate hepatotoxicity is unknown. Two of the seven patients were less than 10 years of age and an aromatic anticonvulsant (primidone, phenobarbital, phenytoin, or CBZ) was concomitantly administered in six cases (222).
Phospholipid fatty liver may develop sildenafil dosage pediatric as early as 4 months of treatment (36,62). The phospholipid accumulation in lysosomes may inhibit phospholipase A 1 or other enzymes (73–86). Fibrosis or cirrhosis (9), acute conﬂuent, necrotizing hepatitis (18), and infrequent fatal hepatic injury suggests a wide range of hepatotoxic presentations (9,46,51,38,80,87,68).
Hepatic tissue levels of amiodarone and desethylamiodarone can be detected several months after treatment has been stopped. Death can follow sildenafil dosage pediatric amiodarone-induced hepatic failure. The presence of the drug or its metabolite may account for the persistent hepatic injury due to strong lipid-binding afﬁnity.
Cardiovascular and Antidiabetic Drugs 603 A Reye’s syndrome–like illness after amiodarone intake was reported (29,77), and increased transaminases and ammonia levels were followed by coma and death. Acute intravenous amiodarone can cause hepatic necrosis or acute hepatitis (50,59).
The appearance of motor neuron disease or parkinsonism strongly influences survival in FTD (Grasbeck, Englund, Horstmann, Passant, sildenafil dosage pediatric & Gustafson, 1999. Genetics remain the only known risk factor for FTLD. FTD tends to occur at a slightly younger age and has the shortest life expectancy from time of presentation.
There is a strong link between FTD and motor neuron disease, and atypical Parkinsonian syndromes, including corticobasal degeneration and progressive supranuclear palsy (Kertesz, Hillis, & Munoz, 1999. Hodges, Davies, Xuereb, sildenafil dosage pediatric Kril, & Halliday, 2002). Talbot, 1995).
Spillantini, Bird, & Ghetti, 1998. The majority of cases are sporadic, but approximately 6% of cases seem to follow an autosomal dominant pattern of inheritance (Chow et al., 1999.
