Please send all feedback to: doc@psychiatrix.com Los Angeles area residents call 818-991-8376 for appt. "Single isomer" medications often represent a modification of existing medication. Many psychiatric medications exist in a "racemic" mix of molecules comprised of mirror-image isomers (enantiomers). These mirror-image molecules bend light in opposite directions. Hence one group is labeled dextro-rotary and the other group is labeled levo-rotary. One of the "single isomers" recently introduced is Lexapro. This is a single isomer form of Celexa, an antidepressant medication. A possible advantage of Lexapro is fewer side effects and greater effectiveness at a lower dose vs. the racemic Celexa. Other single isomer medications will probably be introduced in the future. Unfortunately a single isomer form of Prozac (R-Fluoxetine) never made it through the FDA regulatory process. Perhaps it will return. Please send all feedback to: doc@psychiatrix.com Los Angeles area residents call 818-991-8376 for appt. |
