Cylert (pemoline) is off the U.S. market. Valrelease (diazepam E.R.) failed the U.S. market. All Midrin and generics have been assigned to C4 due to stupid people reporting the psychoactive effects--thanks stupid people! Pondimin(fenfluramine) is long off the U.S. market. Redux(fenfluramine/phentermine) damages heart valves-withdrawn.-apparently reformulated as dexfenfluramine. Talwin(pentazocine) has been withdrawn a long time. Reformulations are available--pentazocine/APAP-- Talacen and pentazocine/naloxone-Talwin NX. Is Placidyl (ethchlorvynol) still available?
