👉 Thioureas are a class of drugs that are used to treat certain types of seizures. They work by blocking the transmission of electrical signals from the brain to the muscles, which in turn helps to stop or reduce the intensity and frequency of seizures. The most common type of thiourea is levodopa, but other medications like carbidopa and bupropion are also used for seizures. Thioureas can be prescribed by a doctor and should only be taken under medical supervision.
