Brief Summary:
The purpose of this study was to determine whether antiepileptic drug phenytoin is effective in the treatment of chronic asthma in children.

Condition or disease Intervention/treatment Phase
Bronchial Asthma Drug: Phenytoin Phase 4

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. It is known that some other neurogenic inflammatory paroxysmal disorders exist, and they are migraine and trigeminal neuralgia. Antiepileptic drug phenytoin is very effective in therapy of trigeminal neuralgia - more than in 70-80% of cases. Other antiepileptic drugs, salts of valproic acid, are effective in the treatment of migraine. 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 perform a double-blind, placebo-controlled 3-month trial for evaluation of phenytoin efficacy in therapy of bronchial asthma in children. Phenytoin is a well-known, comparatively safe and effective antiepileptic drug with low cost. According our previous data, phenytoin is effective drug for asthma therapy in adults.

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

Exclusion Criteria:

  1. History or presence of cardiovascular, renal, neurologic, psychiatric, liver, immunologic, endocrine, infection or other diseases or dysfunctions if they are clinically significant. A clinically significant disease is defined as one which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study.
  2. Patients with active tuberculosis with indication for treatment.
  3. Patients with clinically significant abnormal baseline haematology, blood chemistry or urinalysis or if the abnormal defines a disease listed as an exclusion criterion.
  4. Patients with known allergy, side effects, intolerance/hypersensitivity to investigational drug
  5. Patients currently using MAO inhibitors, tricyclic antidepressants, antiepileptic drugs, narcotic agents.
  6. Patients between 10 and 14, parents or supervisor of patients unlikely, unable or unwilling to comply with the requirements of the protocol.
