Pharmacological Therapy that May Reduce Autistic Behaviors

Some studies have investigated the potential role of Gamma-Aminobutyric Acid (GABA) modulators such as valproate (Depakote), Acamprosate (Campral), and Arbaclofen (Brondine et.al 2016); Memantine (Namenda) and Minocycline (Minocin) (Kumar & Sharma, 2016).

Depakote is an anticonvulsant medication. Acamprosate (Campral) is a GABA analog indicated for maintenance of alcohol abstinence. Arbaclofen is a derivate of Baclofen, a skeletal muscle relaxant. Bumetanide (Burnex) is a chloride co-transporter NKCC1 antagonist diuretic which can reduce intracellular concentration of chloride in neurons. Dipeptide L-carnosine acts by reducing zinc and copper influx near GABA receptors. Riluzole (Rilutex) is used for the treatment of amyotrophic lateral sclerosis (ALS).

Kumar and Sharma (2016) have studied the role of Minocycline and Memantine to reduce maladaptive behaviors. Minocycline is a tetracycline indicated to treat inflammatory lesions. Memantine is used for the treatment of moderate to severe dementia. While the authors did not study its effect specifically in Autistic subjects, they were able to demonstrate that Minocycline and Memantine reduced locomotion, anxiety, brain oxidative and nitrosative stress, inflammation, calcium and blood brain barrier permeability when these symptoms were induced by Valproic acid.

All of the above medications are not yet approved by the FDA for treatment of autism, although they may have potential off label use for autistic individuals.
