Levoamphetamine is a medication used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is a potent CNS (central nervous system) stimulant that increases the production of neurotransmitters in the brain. Levoamphetamine is also known by several synonyms such as l-Amphetamine, L-Amfetamine, Levamfetamine, and Levamphetamine. These synonyms are often used interchangeably to refer to the same drug. While the use of these synonyms may be confusing to some, they serve an important purpose in terms of pharmaceutical identification and classification. Regardless of the term used, Levoamphetamine remains a powerful medication with proven efficacy in treating certain health conditions.
