The Post-finasteride Syndrome: Clinical Manifestation of Drug-Induced Epigenetics Due to Endocrine Disruption

AbstractPurpose of ReviewPost-finasteride syndrome (PFS) is a disorder characterized by a set of clinical symptoms experienced during use or after drug discontinuation. This cluster of symptoms encompasses overall sexual dysfunction (SD), erectile dysfunction (ED), loss of libido, depression, suicidal ideation, anxiety, panic attacks, insomnia, and cognitive dysfunction. To date, there is lack of comprehensive understanding of the biochemical and pathophysiological mechanisms responsible for the adverse effects of finasteride. More importantly, there is lack of knowledge and effective clinical tools for treatments of this condition, resulting in outright dismissal of complaints by individuals afflicted with this syndrome. Psychological symptoms and cognitive dysfunction of PFS are far more serious and difficult to treat than sexual dysfunction symptoms and may lead young men to contemplate, attempt, or even commit suicide. Therefore, an urgent need exists to fill the knowledge gap in physiology, pathophysiology, and clinical management of patients with PFS.Recent FindingsFinasteride treatment impairs biosynthesis and function of neurosteroids, which are critical regulators of central (CNS) as well as peripheral nervous system functions and modulate a host of neurotransmitter receptors, such as gamma amino butyric acid receptors. Thus, finasteride-induced neuroendocrine disruption of biosynthesis of critical signaling molecules results in pathophysiological states, which contr...
