WHAT ARE HYDANTOIN ANTICONVULSANTS AND HOW DO THEY WORK?
Hydantoins are a class of drugs mainly used to treat seizures (anticonvulsant or antiepileptic drugs). Hydantoins reduce seizures by targeting the sodium channel present throughout the nerves. Activation of sodium channels results in the conduction of electrical impulses and the release of neurotransmitters. Higher conduction of electrical impulses can result in higher seizure activity. Thus, hydantoins inactivate the sodium channel and prevent the return of the channel to an active state. As a result, they inhibit the development of seizure activity and reduce the spread of seizures.
HOW ARE HYDANTOIN ANTICONVULSANTS USED?
Hydantoin anticonvulsants are mainly used to treat different types of seizures. They may also be used to treat an irregular heartbeat.
WHAT ARE SIDE EFFECTS OF HYDANTOIN ANTICONVULSANTS?

- Drug withdrawal seizure
- Double vision
- Psychosis (high dose) (a mental disorder characterized by a disconnection from reality)
- Optic nerve damage
- Encephalopathy (brain disease or damage)
- Atrioventricular conduction disorder (conduction between the upper chambers and lower chambers is disrupted)
- Ventricular fibrillation (abnormal heart rhythm in lower chambers of the heart)
- Megaloblastic anemia (a condition in which the bone marrow produces unusually large, structurally abnormal, immature red blood cells)
- Hypocalcemia (low blood calcium levels)
