Japanese drugmaker Kobayashi Pharmaceutical Co. faced a significant setback as shares were poised to fall following the announcement of a recall of supplement pills. The recall was prompted by complaints of kidney issues experienced by the users. Consequently, the stock remained untraded in Tokyo on Monday after the company revealed that an analysis had uncovered 'unintended' elements in the supplements. This development has garnered attention within the industry and has the potential to have a notable impact on the company's position in the market.
