Y49.4: Butyrophenone and thioxanthene neuroleptics

Butyrophenone and thioxanthene neuroleptics are a classification of medications that are often used in the treatment of certain psychiatric conditions, such as schizophrenia. They work by altering the balance of chemicals within the brain. However, as with many medications, there are potential adverse effects. In some cases, these can affect the nervous system, leading to a condition known as neuroleptic-induced movement disorder. This disorder can cause involuntary movements, such as tremors, stiffness, and slow movement. Symptoms often present gradually and can worsen over time if the medication intake is not managed or adjusted. The range and severity of symptoms can vary widely from individual to individual and may be influenced by factors such as the dose of medication and the duration of treatment.
