Abstract
OBJECTIVES: The grant of marketing authorisation (MA) for new medicines requires comprehensive assessment by regulatory authorities. This study sought to identify ophthalmic medicines granted United Kingdom MA and consider trends in licence approvals. METHODS: This retrospective study reviewed published lists of products granted MA by the UK Medicines & Healthcare products Regulatory Agency between January 2001 and December 2018, inclusive. Eye drops and medicinal products intended for ophthalmic use were identified. All regulatory data sources consulted are in the public domain. Data analyses were descriptive. RESULTS: A total of 295 MAs were issued for ophthalmic products between 2001 and 2018, inclusive. Of these 229 (78%) were for single-active substances and 66 (22%) fixed-dose combination (FDC). Approvals for products with single-active substance included ocular hypotensives (115; 50%), antibiotics (48; 22%), allergy medicines (30; 13%), lubricants (18; 8%) and anti-inflammatories (11; 5%). Approvals for FDCs were predominantly ocular hypotensives (56; 85%), with timolol combined with carbonic anhydrase inhibitors (27; 48%) and prostaglandin analogues (26; 46%) accounting for the majority of glaucoma FDCs. Other FDCs were approved for antibiotic/inflammatory (5; 7.5%), pupillary mydriasis (2; 3%), allergy (2; 3%) and ocular surface lubrication (1; 1.5%) products. A median of 16 licences were approved per year (range 7 [2005] to 35 [2011]). CONCLUSIONS: The majority of MAs granted were for single-agent products, particularly ocular hypotensives and antibiotic preparations. Most products were generic versions of well-established active substances. A trend for increased approvals for FDCs is evident, particularly for the treatment of raised IOP.
