Divalproex may be used in the treatment of absence or partial seizures, as a preventive treatment for migraine, and to treat mania associated with bipolar disorder. For headache frequency data, we calculated mean differences (MDs) between valproate and comparator (placebo, active control, or valproate in a different dose) for individual studies and pooled these across studies. The 10 included papers reported data from 10 unique studies, including four trials of divalproex sodium (The doses of valproate investigated in the 10 included trials ranged from 400 to 1500 mg/day. Pooled analysis of post‐treatment mean headache frequencies in two trials (88 participants) demonstrates a slight but significant advantage for topiramate 50 mg over valproate 400 mg (MD ‐0.90; 95% CI ‐1.58 to ‐0.22). The prophylactic treatment of migraine in children is the subject of a separate Cochrane review (Valproic acid (2‐Propylpentanoic acid) was first synthesised in 1882 as analogue of valeric acid, found naturally in valerian. We attempted to identify all relevant published trials, irrespective of language. It's hard to tell if it's any better than previous medications. Efficacy data based on contemporaneous and timed (usually daily) recording of headache symptoms were preferred to those based on global or retrospective assessments. valproate vs valproic acid.

I didn't suffer any immediately obvious side effects and my mood does appear to have been mostly 'stable' since using it. For new studies identified in the present update, two of us completed this assessment independently; for older studies, one of us performed the assessment and a second author reviewed and commented on it.
Disagreements were resolved through discussion. Papers that could not be excluded with certainty on the basis of information contained in the title and/or abstract were retrieved in full for screening. Tremors were a problem. (1 = yes; 0 = no) Each trial thus received a score of 0 to 5 points, with higher scores indicating higher quality in the conduct or reporting of the trial. Evidence‐based guidelines on the drug treatment of migraine have been developed and published by the European Federation of Neurological Societies (EFNS; This review considers the evidence for the efficacy and tolerability of valproate for preventing episodic migraine in adults. We attempted to standardise the unit of time over which headache frequency was measured at 28 days (four weeks) wherever possible. Diagnostic criteria, baseline headache frequency, washout periods for previous medication, rules for rescue medication, and the statistical power of the comparison were handled very variably in the 10 included studies. Cochrane Database Syst Rev. Most commonly used formulations worldwide are sodium valproate alone or a combination of sodium valproate with valproic acid in controlled release tablets; in North America, however, divalproex semisodium or valproic acid alone are used. Although we prefer ORs because of their statistical properties, some readers may find it simpler to interpret the clinical significance of our findings using risk ratios (RRs); we have therefore calculated RRs where appropriate. It is a liquid at room temperature, but it can be reacted with a base such as sodium hydroxide to form the salt sodium valproate, which is solid. . We completed a 'Risk of bias' table for each study, using assessments of random sequence generation (selection bias), allocation concealment (selection bias), blinding of participants and personnel (performance bias), blinding of outcome assessment (detection bias), incomplete outcome data (attrition bias), and selective reporting (reporting bias).

Divalproex Sodium rated 6.5/10 vs Valproic Acid rated 6.2/10 in overall patient satisfaction. Although we attempted to standardise the extraction of headache frequency data to a 28‐day (four‐week) period, this was not possible in every case.
