Abstract: Compositions and methods for treating addiction in a subject are disclosed. In particular, compositions and methods for treating addiction to a dopaminergic psychostimulant are disclosed. In some embodiments, addiction is treated by agonizing bile acid receptors in the subject. For example, in some embodiments, the method comprises administering to the subject a therapeutically effective amount of a composition comprising a therapeutically effective amount of a bile acid receptor agonist. In some embodiments, the method comprises surgically diverting bile acids in the subject in a manner suitable to increase circulating bile acids in the subject.

Abstract: The present invention involves the use of GLP-1 and its analogs or GLP-1 receptor agonists to modulate dopamine transporter signaling. The implications of this ability include the use of MT-1 and its analogs or GLP-1 receptor agonists, such as exendin-4, to blunt behavioral response to addictive drugs, to decrease drug dependence, to prevent drug abuse relapse, and to treat brain disorders such as neuropsychiatric disorders including ADHD. The present invention also involves the use of GLP-1 and its analogs or GLP-1 receptor agonists to activate GLP-1R in penile tissue, such as for the treatment of erectile dysfunction either as a monotherapy or in combinations with other treatments, such as PDE 5 inhibitors.
