About Chlorthalidone
Chlorthalidone is approved for hypertension and oedema in heart failure, hepatic cirrhosis or nephrotic syndrome. In South Korea, prescription medicines (전문의약품) are dispensed only against a doctor's prescription, while general medicines (일반의약품) are sold OTC at pharmacies. The 2000 medical reform separated dispensing from prescribing — doctors prescribe, pharmacists dispense.
Mechanism and action
Chlorthalidone blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis.
Brands and generics in South Korea
In South Korea, Chlorthalidone is typically dispensed as one internationally recognised brand along with their corresponding authorised generics. Korean pharmacies (약국) are licensed by the MFDS and present in every neighbourhood, often clustered near clinics. Pharmacists verify each prescription and provide medication counselling at dispensing, with the National Health Insurance Service covering most prescription costs. Brand-to-generic substitution is decided by the pharmacist under local MFDS (Ministry of Food and Drug Safety) equivalence rules, and the price difference in KRW is usually substantial.
Online and tele-prescribing access
Online prescription dispensing is heavily restricted in South Korea — telemedicine and remote prescribing were expanded only temporarily during COVID-19 and remain limited. Direct online sale of prescription medication is not permitted; consumers can browse OTC products on chain-pharmacy websites. For Chlorthalidone specifically, the legal online options in South Korea depend on its Rx-or-OTC classification under MFDS (Ministry of Food and Drug Safety).
