APAKAH MAKSUD HYOSCYAMINE dalam CORSICA?
Hyoscyamine
Hyoscyamine adalah alkaloid tropane. Ia adalah metabolit sekunder yang terdapat dalam tumbuhan tertentu dari keluarga Solanaceae, termasuk henbane, mandrake, jimsonweed, tomato dan malam-malam yang mematikan. Ia adalah isomer levorotary atropin dan oleh itu kadang-kadang dikenali sebagai levo-atropin. Hyoscyamine tidak boleh dikelirukan dengan hyoscine, nama alternatif yang lebih lama untuk scopolamine antikolinergik yang dijumpai malam-malam yang berkaitan dengannya yang mana ia adalah pendahulu. Nama jenama untuk hyoscyamine termasuk Symax, HyoMax, Anaspaz, Egazil, Buwecon, Cystospaz, Levsin, Levbid, Levsinex, Donnamar, NuLev, Spacol T / S dan Neoquess.
