Taisho Pharmaceutical, a world-class OTC drug manufacturer, was founded in 1928 and had sales of more than 200 million yen in 2017. Taisho Pharmaceutical is involved in more than a dozen countries around the world, and has R&D and manufacturing in the United States, Mexico, Thailand, Malaysia, China and other places. Among them, Taisho cold medicine is a standing medicine for Japanese families, and health care functional drinks also entered the Chinese market in the early years, and in the field of ophthalmic preparations, Taisho is also quite popular.
 
In Taisho eye drops, IRIS CL i2 is the only single-dose artificial tears that do not contain any preservatives, simulating natural tears, with simple and safe ingredients, mainly sodium chloride and potassium chloride, adding a small amount of taurine to activate the metabolism of eye tissue, if there are symptoms such as dry eyes, this artificial tears can be used as the first choice. The Chinese Pharmacopoeia stipulates that conventional eye drops should not be used for more than 4 weeks after opening to prevent contamination by airborne microorganisms, and disposable artificial tears such as IRIS CL i2, which are designed in thin tubes, need to be discarded on the same day as Allergan's Bright Vision eye drops. A box of 30 sticks, one contains 0.4ml, which is equivalent to about 50 yuan.
 
Taisho also has children's eye drops specially prepared for children, which belong to the third category of medicines and have fewer side effects. However, its antiseptic system still uses the traditional benzalkonium chloride, which is not as good as Nissan's Xiaoletun eye drops, and Taisho's formula contains neoss constriction pupil ingredient to improve the regulatory function of the ciliary muscle, and long-term frequent use may cause discomfort. If you just want to increase the moisturity of your child's eyes, artificial tears are more appropriate.
 
The IRIS Neo and IRIS AG series, which soothe eye fatigue, are enhanced with cooling ingredients such as peppermint and camphor to give them the signature cooling sensation of Japanese eye drops. Other series of eye drops are lackluster, not much different from the old versions of Rohto and Towering eye drops, and mostly use traditional antiseptic systems and aminocaproic acid, tetrahydrozoline and other ingredients to reduce inflammation and redness.
 
Taisho Pharmaceutical has not officially entered the Chinese eye drops market, and none of the Taizheng eye drops currently circulating in the market have not been approved by the Food and Drug Administration, so consumers are advised to choose their purchase channels carefully.
