Valproic acid is available as three different entities diabetic nephropathy order cheap glipizide on-line, and all of them are prescribed as val- proic acid equivalents: valproic acid diabetic diet resources cheap glipizide 10 mg otc, sodium valproate (the sodium salt of valproic acid) diabetes symptoms 21 year old order discount glipizide online, and divalproex sodium (a stable coordination compound consisting of a 1:1 ratio of valproic acid and sodium valproate). When given intravenously, it should be diluted in at least 50 mL of intravenous solution, and given over 1 hour (injection rates should not exceed 20 mg/min). For oral use, a syrup (50 mg/mL), soft capsule (250 mg), enteric coated capsules (125 mg, 250 mg, and 500 mg), sustained-release tablets (250 mg and 500 mg) and sprinkle capsule (125 mg, used to sprinkle into foods) are available. The enteric coated capsules are not sustained- release products, but only delay the absorption of drug after ingestion. The oral bioavailability of valproic acid is very good for all dosage forms and ranges from 90% for the sustained-release tablets to 100% for the other oral dosage forms. Usually, val- proic acid doses are not fine-tuned to the point of directly accounting for the difference in valproic acid bioavailability. Rather, clinicians are aware that when valproic acid dosage forms are changed, the serum concentration versus time profile may change. Because of this, most individuals recheck valproic acid steady-state serum concentrations after a dosage form change is instituted. The typical maintenance dose for valproic acid is 15 mg/kg/d resulting in 1000 mg or 500 mg twice daily for most adult patients. Similarly, if children receive therapy with other antiepileptic drugs that are enzyme inducers, clearance is 20–30 mL/h/kg and half-life is 4–6 h. The volume of distribution may be larger because of reduced plasma protein binding (free fraction ≈29%). Protein binding may be reduced and unbound fraction may be increased owing to hypoalbuminemia and/or hyper- bilirubinemia (especially albumin ≤3 g/dL and/or total bilirubin ≥2 mg/dL). However, the effects that liver dis- ease has on valproic acid pharmacokinetics are highly variable and difficult to accurately pre- dict. It is possible for a patient with liver disease to have relatively normal or grossly abnormal valproic acid clearance and volume of distribution. For example, a liver disease patient who has relatively normal albumin and bilirubin concentrations can have a normal volume of dis- tribution for valproic acid. An index of liver dysfunction can be gained by applying the Child- Pugh clinical classification system to the patient (Table 12-3). The Child-Pugh score consists of five laboratory tests or clinical symptoms: serum albumin, total bilirubin, pro- thrombin time, ascites, and hepatic encephalopathy. Each of these areas is given a score of 1 (normal) to 3 (severely abnormal; Table 12-3), and the scores for the five areas are summed. The Child-Pugh score for a patient with normal liver function is 5 while the score for a patient with grossly abnormal serum albumin, total bilirubin, and prothrombin time values in addition to severe ascites and hepatic encephalopathy is 15. A Child-Pugh score greater than 8 is grounds for a decrease of 25–50% in the initial daily drug dose for valproic acid. As in any patient with or without liver dysfunction, initial doses are meant as starting points for dosage titration based on patient response and avoidance of adverse effects. Since the drug has been associated with hepatic damage, valproic acid therapy should be avoided in patients with liver disease whenever possible. Valproic acid serum concentrations and the presence of adverse drug effects should be monitored frequently in patients with liver cirrhosis. Elderly patients have lower valproic acid oral clearance rates and higher unbound frac- tions than younger adults so lower initial doses may be used in older individuals. Val- proic acid therapy also decreases the clearance and increases steady-state concentrations of other drugs including zidovudine, amitriptyline, and nortriptyline. As a general rule, when valproic acid is added to a patient’s drug regimen, an adverse effect from one of the other drugs must be considered as a possible drug interaction with valproic acid. Cime- tidine, chlorpromazine, and felbamate are examples of drugs that decrease valproic acid clearance and increase valproic acid steady-state concentrations. Because valproic acid is highly protein bound, plasma protein binding drug interactions can occur with other drugs that are highly bound to albumin. The drug interaction between valproic acid and phenytoin deserves special examination because of its complexity and because these two agents are regularly used together for the treatment of seizures.
