OBJECTIVE
To summarize the pharmacology, pharmacokinetics, efficacy, and safety of acetazolamide and to evaluate its therapeutic role in patients with epilepsy.
METHODS
A computerized search of the MEDLINE (OVID) database (1966-1994) was used to identify publications regarding acetazolamide. The MEDLINE search was supplemented by information from textbooks.
METHODS
Included were English-language review articles, clinical trials, cohort studies, and case reports. Topics investigated included basic pharmacology, therapeutics, toxicology, adverse reactions, dosage, administration, and pharmacokinetics of acetazolamide.
RESULTS
Acetazolamide, a carbonic anhydrase inhibitor, has been approved for the treatment of epilepsy since 1953. Acetazolamide is primarily used in combination therapy with other antiepileptic medications in both children and adults although it may be used as monotherapy. Drug concentration monitoring has not been found to be routinely beneficial. Adverse effects include kidney stones, metabolic acidosis, lethargy, appetite suppression, paresthesias, and rare blood dyscrasias. Partial tolerance may develop to the antiepileptic activity.
CONCLUSIONS
Acetazolamide is a beneficial adjunctive agent in the pharmacotherapy of epilepsy and should be considered in refractory epilepsy. Although it may be useful in partial, myoclonic, absence, and primary generalized tonic-clonic seizures uncontrolled by other marketed agents, acetazolamide has been inadequately studied by current standards and its use has been limited.
