I'm teaching English in Korea and I'm trying to identify some of the pills they're giving me for my frequent bouts with bronchitis. It's an oval pill with "LG" and "320" stamped into the left and right halves on the same side of the pill. The opposite side is blank. Some medicines prescribed here in Korea are produced by global manufacturers like Pfizer and are somewhat easy to identify. Some not much. With this one I can't tell if it's an antibiotic, or for suppression of symptoms... Can anyone help?
