Swiss pharmaceutical giant Roche has stopped delivering its medicines to some Greek hospitals as they have failed to pay their bills.
"There are hospitals who haven't paid their bills in three or four years," a Roche spokesman said on Sunday, quoting chief executive Severin Schwan.
"There comes a point where the business is not sustainable anymore."
Schwan noted in particular that Greek public hospitals "have the habit of not paying the pharmaceutical industry", unlike pharmacies.
Since the supply disruption, some hospitals have began repaying their bills, said Schwan, stressing it is because "they understood that their reputation vis a vis the patients was at risk".
While halting deliveries to the hospitals this year, the company has increased its deliveries to pharmacies, which pay their bills more regularly, said Schwan.
