What is a Generic Drug?
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Product Details
Description
Haldol (Haloperidol) is a medication commonly prescribed to treat mental health disorders, including schizophrenia, acute psychosis, and bipolar disorder. It belongs to a class of drugs known as antipsychotics, which work by blocking the effects of dopamine, a neurotransmitter in the brain.
Schizophrenia is a chronic mental illness characterized by disturbances in thinking, emotions, and behavior. Symptoms can include hallucinations, delusions, disorganized thinking, and a lack of motivation or social withdrawal. Haldol helps to alleviate these symptoms and improve overall functioning.
Haldol works by blocking dopamine receptors in the brain, which helps to restore the balance of chemicals and reduce psychotic symptoms. It is available in various formulations, including oral tablets, injectable solutions, and long-acting depot injections for maintenance therapy.

Popular Questions
Haloperidol primarily works by blocking dopamine receptors in the brain, particularly those in the mesolimbic and mesocortical pathways. This action reduces the activity of dopamine, a neurotransmitter involved in various brain functions, including movement, reward, and motivation. By reducing dopamine activity, haloperidol can help manage symptoms of psychosis, such as hallucinations and delusions, as well as other conditions like Tourette's syndrome and severe behavioral problems. However, this mechanism can also lead to side effects related to movement and other dopamine-regulated functions.View allHaloperidol (Haldol) is a medication used to treat a variety of mental and mood disorders, including schizophrenia and schizoaffective disorders. It works by helping to restore the balance of certain natural substances in the brain. Haloperidol is also used to treat uncontrolled movements and outbursts of words or sounds related to Tourette's syndrome, and for severe behavioral problems in children when other treatments or medications have not worked.
