What is Depakote?

First sold in 1983 for epilepsy treatment, Depakote is the brand name for sodium divalproex, a compound made of sodium valproate and valproic acid. Depakote was approved for treatment of bipolar disorder in 1995 and migraine headaches in 1996. Manufactured by Abbott Laboratories, the drug can be ingested in a variety of ways including pill, injection, or liquid form. Regardless of the method ingested, Depakote is used to treat certain medical conditions by increasing the GABA (a neurotransmitter) in the brain and helping to reduce voltage sensitive sodium channels.Depakote has been linked to several serious side-effects including pancreatitis, liver toxicity, suicide, and birth defects (cardiovascular malformations, neural tube defects and facial deformities).

Other Uses

Currently Depakote is only approved to combat and control epileptic seizures, bipolar mania, and the prevention of migraines. Although Abbott Laboratories has conducted clinical trials to use Depakote to treat dementia, these trials were suspended when patients experienced negative side-effects including anorexia, somnolence, and dehydration. From 1998 to 2006 the company illegally marketed the use of Depakote for the control of agitation and aggression in elderly dementia patients. From 2001 to 2006 Abbott Laboratories illegally marketed Depakote for the treatment of schizophrenia. Neither actions were approved by the Federal Drug Administration. In 2012 Global Health Care Company Abbott Laboratories Inc. pled guilty to criminal and civil charges for promoting Depakote for unauthorized purposes and agreed to pay an estimated $1.5 billion in fines and penalties. This payout is the second largest payout to date by a drug company. The Attorney General for the case stated that this move was an effort to “stop this type of activity…and send a strong message to other companies.”

Depakote Usage and Statistics

Antiepileptic therapies which treat patients with epilepsy is big business in the United States. In fact, experts estimate that more than 2.5 million people may suffer from some type of seizure disorder, which generates billions of dollars in healthcare costs. In fact, prescription medications for the treatment of epilepsy are estimated at more than $10 billion dollars per year. Depakote has made billions of dollars for Abbott Laboratories since its market release. Abbot Laboratories, however, is just one of the major players in the market. Other manufacturers of popular Antiepileptic medications include Johnson & Johnson, Pfizer, Cephalon, and GlaxoSmithKline. Sales have declined substantially with the introduction of generic competition in 2008, which drove down the price for antiepileptics. Another issue which damaged the sale of the product was the criminal charges against Abbott Laboratories for the promotion of Depakote for the off-label treatment for certain conditions.

How Depakote Works

Depakote has helped millions of patients suffering from epilepsy, migraines, and bipolar disorder. Medical experts are not exactly sure how the drug works, but they know that it blocks sodium channels in neurons, which can lower neuron activity. Experts also claim it “augments the activity of a GABA-synthesizing protein, GAD, and restrict a GABA-degrading protein, GABA-T.” The result is overactive neurons seem to calm.

Generic medications, although criticized that they may not be as effective as their branded counterparts, now dominant the market for epileptic treatment. The only remaining antiepileptic currently in the market that has not lost its patent exclusivity is Lyrica, which will expire in 2018. There is concern, however, that certain types of antiepileptic medications may pose an increased risk for suicidal thoughts and actions.

In clinical trials subjects who used Depakote showed significant improvement in the reduction of the frequency of their seizures. According to the study, “seizure frequency was calculated to reflect the median number of seizures during an eight-week measurement period versus an eight-week treatment period with Depakote.” Subjects did experience certain common side-effects from Depakote. The most common side-effects included vomiting, abdominal pain, anorexia, and tremors.
