Hyperacusis refers to a condition when any sound becomes intolerable to a person. Generally, the patients of hyperacusis feel pain in their ears by any sound. This dreadful disease can attack anyone through various ways. It never spares the youths also. While some people develop hyperacusis over a longer period, some get that suddenly after hearing a heavy sound. Apart from that, there are other reasons which can create hyperacusis e.g. severe headache, ear irrigation, adverse drug reaction, Williams’ syndrome, Autism, Bell’s palsy, Asperger syndrome, minor head injury, chronic ear infections and others. As medical science has advanced a lot in this modern era, there is nothing to be afraid about hyperacusis. Nowadays, there are several ways to cure Hyperacusis. Carbamazepine has proved as an effective medicine to cure hyperacusis.

Carbamazepine (’CBZ’) is mainly an anticonvulsant and mood stabilizing drug. It works faster than other medicines to cure hyperacusis. Its derivatives are well understood. Carbamazepine has large number of voltage-gated sodium channels. Actually, they have the molecular pores that permit brain cells or neurons to produce certain electrical events. These electric signals make the neurons able to communicate over long distance. As the gates of the sodium channels are opened to commence the action, the obsolete nerve cells become active. Carbamazepine helps to change the inactivated state of brain cells and also keeps them less excited. Carbamazepine is sold at the market under different names, such as- ‘Tegretol’, ‘Biston’, ‘Calepsin’, ‘Carbatrol’, ‘Epitol’, ‘Equetro’, ‘Finlepsin’, ‘Sirtal’, ‘Stazepine’, ‘Telesmin’, ‘Timonil’, ‘Trimonil’, ‘Epimaz’ and ‘Degranol’. Doses of Carbamazepine must be taken according to the prescription of medical practitioners.
