Detailed Description:

Effective therapy of asthma still remains quite serious problem. According GINA definition, asthma is an inflammatory disorder. Consequently, modern pharmacotherapy of asthma provides wide use of anti-inflammatory drugs. But asthma also is a paroxysmal disorder: many specialists and even some guidelines underline paroxysmal clinical picture of asthma. Besides this, according to some authors, neurogenic inflammation may play important role in asthma mechanism. But some other neurogenic inflammatory paroxysmal disorders exist, and they are migraine and trigeminal neuralgia. Some antiepileptic drugs, like carbamazepine and valproate, are very effective in therapy of migraine and trigeminal neuralgia - more than in 80% of cases. If bronchial asthma also is paroxysmal inflammatory disease, like migraine and trigeminal neuralgia, it is possible that some antiepileptic drugs also are very effective in asthma therapy.

We performed a double-blind, placebo-controlled 3-month trial for evaluation of oxcarbazepine efficacy in therapy of bronchial asthma. Oxcarbazepine is antiepileptic drug of new generation, produced by Novartis, and it is more effective and safe derivative of well-known antiepileptic drug carbamazepine.

Comparison: Patients received investigational drug in addition to their usual routine antiasthmatic treatment, compared to patients received placebo in addition to their usual routine antiasthmatic treatment.
