Upon analysis, this pharmacological agent seems to be an agonist of the NMDA receptor, with an unknown [Km]. Because excess Glutamate causes excitotoxicity and neuronal apoptosis, Carisoprodol overdose may also lead to NMDA related toxicity, thus inducing seizures at high doses, and muscle relaxation upon administration. Carisoprodols structural similarity to Meprobamate indicates GABAergic activity, including GABA A agonism, similar to the mechanism of benzodiazepines. This will allow for further muscle relaxation and anxiety reduction. Therefore, Carisoprodol, at low to moderate dosages, may be clinically indicated for absent seizures, yet exacerbate Tonic-clonic seizures. Pharmacokinetics
Carisoprodol has a rapid, 30-minute onset of action, with the aforementioned effects lasting about two to six hours. It is metabolized in the liver via the cytochrome P450 oxidase isozyme CYP2C19, excreted by the kidneys and has about an eight-hour half-life. In patients with low levels of CYP2C19 (poor metabolizers), standard doses can lead to increased concentrations of carisoprodol (up-to a four-fold increase). A considerable proportion of carisoprodol is metabolized to meprobamate, which is a known addictive substance; this could account for the addictive potential of carisoprodol (meprobamate levels reach higher peak plasma levels than carisoprodol itself following administration).
Whereas haemodialysis involves blood being filtered through a dialyser, which consists of a semi-permeable membrane where toxins including urea are removed from the blood. Haemodialysis also filters blood quicker than peritoneal dialysis.Intravenous immunoglobin treatments can be used to support the patients immune system as well as medication with Prednisolone to reduce inflammation.Sensorineural hearing loss is a common symptom in Epstein syndrome and can be treated with cochlea implants. Cochlea implants have four main parts including the electrode array, the transmitter, the receiver/stimulator and the microphone. The microphone is positioned behind the ear and receives sound waves, the processor then converts the sound into electrical signals. These electrical signals are further converted into electrical impulses in the cochlea where the transmitter is located, which in turn sends the signal to the auditory nerve. This results in a nervous impulse sent to the brain where the ‘sound’ is deciphered. Prognosis
In most case Epstein syndrome patients will endure early-onset end-stage renal disease (ESRD) at the end of adolescence. Expected kidney failure means patients will need renal transplants in the near future. Notable cases
In a study which investigated suitable management for severe Epstein syndrome, four patients were observed. Patient 1 demonstrated a common background and symptoms for Epstein syndrome. Patient 1 was a male who was initially diagnosed with chronic idiopathic thrombocytopaenia purpura in early childhood and then macrothrobocytopaenia. He progressed to kidney failure and began haemodialysis at seventeen years old.
