The domestic narcotic-analgesic and anesthetic market has grown on the back of an aging population and rising demand for endoscopy and cosmetic procedures, with one estimate putting the combined size of the two markets at close to KRW 200bn a year.
Structurally, narcotics and anesthetics have a quasi-monopoly character because the government limits the number of licensed manufacturers per active ingredient, and a small number of firms including Hana Pharm have shared the market for years.
More recently, however, a new drug based on remimazolam has entered a prescription market long dominated by propofol and midazolam, with observers noting this could reshape the existing prescribing landscape.
Hana Pharm holds the domestic exclusive rights to this remimazolam-based drug (Byfavo), putting it in a position to both benefit from and be exposed to risks from any market restructuring.
Meanwhile, the broader domestic pharmaceutical industry, heavily weighted toward generics, is exposed to government drug-pricing policy, and the recent confirmation of a 45% price cut for generic drugs is cited as a burden on the profitability of generics-centered companies.
In 2025, average operating margin among KOSPI-listed pharmaceutical companies fell to 4.97% from the prior year, while Hana Pharm posted a 10.78% margin, placing it among 15 companies with double-digit margins and keeping it near the top of the sector.
In terms of competitive landscape, Mundipharma, Hanlim Pharm, Janssen, and Pfizer are cited as key players in the anesthetic market, while Samjin Pharmaceutical is cited among mid-tier competitors in the cardiovascular and digestive generics market.
