Adverse effects of propyphenazone

There have been case reports describing risk of acute inferior myocardial infarction with low atrial rhythm due to propyphenazone (Kounis syndrome).^[2]^{[citation needed]}

Countries that have banned propyphenazone

Excerpt from WHO comments:

“Propyphenazone, a pyrazolone derivative with anti-inflammatory, analgesic and antipyretic activity, was introduced in 1951 for the treatment of rheumatic disorders. As it is structurally related to aminophenazone it has been associated with severe blood dyscrasias. However, it cannot be transformed into potentially carcinogenic nitrosamines and has therefore been widely used as a replacement drug for aminophenazone. In certain countries, products containing propyphenazone have now been restricted in their indications, whereas in others they are still available, sometimes as over-the-counter preparations.”^[3]

Sri Lanka^[4]
South Korea^[4] - as reported by PharmAsia News in 2009:

“Amid rising claims that it isn't moving fast enough to counter public concern over the safety of OTC painkillers, Korea FDA has banned Bayer Korea's painkiller Saridon-A, Samjin Pharm's Geworin and 26 other products from being prescribed or sold over the counter to those under 15 years of age.”^[5]

Malaysia^[4]
Thailand^[4]
Turkey - production and sale banned in January 1986 due to incidence of severe adverse reactions.^[3]
India- Still in use. Saridon tablets contain 150 mg/tablet.
