'''Methapyrilene''' is a ] and ] of the ] ] which was developed in the early 1950s. It has relatively strong ] effects, to the extent that its primary use was as a medication for ] rather than for its antihistamine action. Together with ], it was the main ingredient in '''Sominex''', '''Nytol''', and '''Sleep-Eze'''. It also provided the sedative component of '''Excedrin PM'''. All of these products were reformulated in the late 1970s because methapyrilene was demonstrated to cause ] in rats when given chronically.
