Patent Claims:	1. A method of treating seizures, which comprises administering a formulation of oxacarbazepine having improved bioavailability, wherein said oxacarbazepine consists essentially of oxacarbazepine having a maximum residue on a 40 .mu.m sieve of less than or equal to 5%. 2. The method according to claim 1 wherein said maximum residue on a 40 .mu.m sieve is less than or equal to 5%. 3. The method according to claim 1 wherein said formulation is substantially free from particles greater than or equal to 40 .mu.m in size. 4. The method according to claim 1 wherein the seizures results from the onset of epilepsy. 5. A method of treating seizures, comprising oral administration of a formulation of oxacarbazepine, wherein said formulation comprise a therapeutically effective dose of oxacarbazepine and wherein said oxacarbazepine has a median particle size of approximately 2 .mu.m to 12 .mu.m. 6. The method according to claim 5 wherein said oxacarbazepine has a median particle size of approximately 4 .mu.m to 10 .mu.m. 7. The method according to claim 5 wherein said oxacarbazepine has a median particle size of approximately 6 .mu.m to 8 .mu.m. 8. The method according to claim 5 wherein said oxacarbazepine has a maximum residue on a 40 .mu.m sieve of less than or equal to 5%. 9. The method according to claim 5 wherein said oxacarbazepine has a maximum residue on a 40 .mu.m sieve of less than or equal to 2%. 10. The method of claim 1, wherein said oxacarbazepine has a median particle sie of approximately 2 .mu.m to 12 .mu.m.
