Pharmacology
Methampyrone is a potent nonnacrcotic analgesic - antipyretic drug. It is a pyrazolon derivative with therapeutic efficacy equivalent to that of acetosal, the standard drug for the nonnarcotic analgesic - antipyretic class. It causes less gastric irritation than acetosal and does not produce the acid - base or metabolic effects of salicylate.
However, it has been implicated for many years to cause a high incidence of agranulocytosis. An epidemiologic study of international scale involving about 30 milion people had been especially designed to study this matter. 
The study was completed just recently and the results showed that methampyrone, in fact, accounted for only a very low incidence of agranulocytosis.
Trimethylxanthine is commonly added to an analgesic as an analgesic adjuvant. in a dose of 50 mg or more, trimethylxanthine has been shown to enhance the analgesic efficacy of acetosal and acetaminophen ; in this case methampyrone should not be an exception.
