Webb25 jan. 2024 · Divalproex sodium/valproic acid (VPA) is used with therapeutic plasma blood levels between 45 and 125 μg/ml to treat complex partial seizures, simple and complex absence seizures, migraines, bipolar mania, and schizoaffective disorders. WebbValproic acid (VPA) is broadly used in the treatment of neuropsychiatric disorders, and it is also prescribed for epilepsy, migraine, and mood disorders. The commonly adverse events associated with VPA treatment are fatigue, gastrointestinal disturbances, weight gain, tremor, hair loss, thrombocytopenia, and an increase in hepatic enzymes.

WebbResults: A total of 851 VPA levels and concomitant platelet counts were analyzed in 265 patients. Of these, 17.7% of patients experienced at least one episode of thrombocytopenia (platelet count ≤ 100,000/μl) after exposure to divalproex sodium. A significant negative correlation was found between VPA levels and platelet counts. WebbTherapeutic drug monitoring results of valproic acid revealed that 58% of Chinese patients taking valproic acid had the drug in therapeutic levels. The plasma VPA levels were found in sub-therapeutic level in 29% of patients and 13% patients had found in toxic levels.

Fortunately, at supratherapeutic plasma concentrations, the protein-binding sites become saturated and VPA circulates as a largely “free” drug more amenable to removal via dialysis4. careening catalog immemorial
