Uses

Indications

Savi Gabapentin 300 medicine is indicated in the following cases:

  • Support treatment in local epilepsy. On experimental animals, the drug has anti -stretching effects after the limbs when shocking electricity and also inhibits the seizures caused by pentylentetrazole. Effective in both experiments are similar to Valproic acid but unlike Phenytoin and carbamazepine, the chemical structure of Gabapentin is similar to neurotransmitter inhibitors, gamma - aminobutyric acid (GABA), but Gabapentin does not directly affect GABA receptors, does not replace the structure, liberation, transformation and acquisition of GABA.

    In In vitro studies with Gabapentin marked by radiation, there is a position of Gabapentin associated with rat brain, including new cortex and hilly area. The strong binding force with protein in the animal brain tissue has been identified as a small auxiliary source for the voltage to activate calcium channels. However, Gabapentin's connected functional correlation, if any, still needs to be clarified.

    pharmacokinetic pharmacokinetics

    gabapentin absorbed through the gastrointestinal tract under saturated mechanism (when the dose increases, bioavailability decreases). The drug reaches the peak concentration in plasma after drinking 2 hours and reaches a stable concentration after 1-2 days. The effective serum concentration of the drug has not been determined. However, in a study, the number of convulsions only decreased in people with gabapentin serum levels per mg/liter (11.7 micromol/liter). Gabapentin plasma concentration is generally within 2 mg/liter (2 micrograms/ml) to 20 mg/liter (20 micrograms/ml).

    Birth is about 60% when used at a dose of 1.8 g/24 hours and does not correspond to the dose, even when the dose increases over 1.8 g/24 hours of competition, it will decrease (bioavailability of about 35% when used with 4.8 g/24 hours). Food less affecting the speed and level of absorption.

    In elderly patients and patients with impaired renal function, plasma gabapentin clearance is reduced. Gabapentin can be eliminated from plasma by hemolysis, so the dose adjustments for these patients are needed.

    gabapentin is distributed throughout the body, entering breast milk, linking with very low plasma proteins (

    Gabapentin is almost no metabolic in the body and excreted mainly through the kidneys in a constant form. Half of the mineral gabapentin 5 to 7 hours in people with normal kidney function.
