According to the American "Pharmaceutical Executive" (Pharmaceutical Executive), in 2017, Allergan ranked 12th in the ranking of the top 50 global pharmaceutical companies, with global sales of 19.258 billion US dollars, and the cyclosporine eye drops for ophthalmic treatment are one of its best-selling drugs, and Allergan is gradually penetrating the Chinese medical aesthetic market.
 
Allergan entered the Chinese market in 2009 and launched products in the fields of ophthalmology and medical aesthetics, reaching the highest level in the industry. In 2017, its heavyweight ophthalmic new drug Ozurdex (dexamethasone intravitreal implant 0.7mg) has obtained the import drug license (IDL) from the CFDA, which is the first intravitreal injection drug approved for the treatment of retinal vein occlusion (RVO) in China, which can benefit 4.7 million RVO patients in China.
 
Allergan is mainly engaged in four modules in the field of ophthalmology: glaucoma, dry eye, extraocular inflammation and fundus, but it has a conservative attitude towards China's over-the-counter OTC eye drops market, and its product line is relatively simple, all of which are "old products" that have been on the market for many years. Its Bright, Fresh, Clear and Xiaolaiwei are all artificial tear brands, namely sodium carboxymethylcellulose eye drops, which are used to soothe dry eyes or reduce the burning and stinging sensation of the eyes caused by exposure to sunlight and sand. These moisturizing eye drops have simple ingredients and few side effects, but they are not particularly effective in eliminating redness or anti-inflammatory.
 
The higher the concentration of sodium carboxymethyl cellulose, the more long-term moisturizing it can be for the eyes, and these four products are mainly distinguished by the concentration and dosage of sodium carboxymethyl cellulose. Bright Vision and Sunny Bright are single doses, and Shine Vision's sodium carboxymethyl cellulose concentration is higher, which can be chosen by people with severe dry eyes, while people with moderate to mild dry eyes are preferred Bright Vision eye drops, that is, the most simple version of Allergan Refresh plus eye drops. Freshening and decoagulation are multi-dose eye drops, both of which use new preservatives to "pure", which can be decomposed by light without cumulative side effects, minimizing the risk of irritation and corneal damage caused by preservatives.
 
Allergan eye drops are priced at about 50 yuan in China, and consumers prefer its single dose of artificial tears, using one a day, because a single dose of artificial tears does not contain preservatives, there may be a risk of bacterial invasion after opening, and it must be covered in time.
