Medications (also known as pharmaceutical drugs, medicines, or medicaments) can be loosely defined as chemical substances intended for use in the medical diagnosis, cure, treatment, or prevention of disease. Some of these substances, such as piracetam, are also sometimes taken as nutritional supplements.
Many different kinds of medication are used to treat autistic people. These include but are not limited to: anticonvulsants, antidepressants, antipsychotics, anxiolytics, hormones, immune globulins, psychostimulant medications and many others. None of these medications was initially designed specifically to treat autism, but instead target other conditions such as high blood pressure, epilepsy, ADHD and drug dependency.
There are various ways in which these medications can be classified, such as by chemical properties, mode or route of administration, biological system affected, or therapeutic effects. We have categorised them by the principal biological system affected because most medications designed to help autistic people target the central nervous system and it makes sense to group these together.
Medications are available in many forms including tablets, capsules, liquids, infusions and injections. The same medication may have several different brand names. For example, the antipsychotic haloperidol is marketed as Dozic, Haldol, and Serenace.
Research suggests that most medications have no effect on the core features of autism. However, some medications may have some benefits. For example,
Very little high-quality research evidence supports the effectiveness of most other medications for treating the other issues facing people on the autism spectrum
The central nervous system (CNS) consists of the brain and spinal cord. The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory. The spinal cord carries signals between the brain and nerves in the rest of the body.
There are a number of medications which are designed to improve or repair CNS functions and many of these have been suggested as treatments for autistic people.
Those medications include anticonvulsants, antidepressants, antipsychotics, anxiolytics and hypnotics, cholinesterase inhibitors, NMDA receptor antagonists, opioid receptor antagonists, and psychostimulants.

The cardiovascular system, also known as the circulatory system includes the heart, blood vessels and blood. The respiratory system includes the nose, mouth, sinuses, throat, bronchial tubes and lungs.
The two systems are responsible for ensuring the body receives an adequate supply of oxygen and that carbon-dioxide is expelled from the body.
There are a number of medications which are designed to improve or repair cardiovascular and respiratory functions and some of these have been suggested as treatments for autistic people.
They include antihistamines, antihypertensives, calcium channel blockers and diuretics.

The endocrine system is up of various glands such as the hypothalamus gland, pituitary gland, thyroid gland, pineal gland etc..
Glands produce and secrete hormones - chemical substances that regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.
There are a number of medications which are designed to improve or repair the endochrine system and many of these have been suggested as treatments for autistic people.
Those medications include hormones (such as melatonin, oxytocin and secretin) or medications (such as leuprolide) which are designed to change the amount and effect of hormones (such as testosterone).

The immune system is made up of a network of cells, tissues, and organs that work together to protect the body against disease and infections.
The medications in this section are all used to treat problems in the immune system. For example, antibiotics are used to treat, and in some cases prevent, bacterial infections.
A number of these medications have been suggested as treatments for autistic people including antibiotics, antifungals and immune globulins.
