White oblong pill - imprint 'ru..?' [pill is broken in half]

[crawfish79]

I found this pill in an old blazer. It is broken in half and only half of the imprint is there [actually it's NOT an imprint but rather black text printed on the pill].

Nothing is on the reverse side. 'RU' are definitely the first two letters and the third letter looks like it could be a 'F' , 'P', or a 'R'.

I have searched drugs.com, and Google but can't find anything close. Can anybody please help??? My email address is: crawfordhoke@yahoo.com

Thanks everybody!

The only thing I'm finding has more then three letters, is that possible? Maybe RUFEN6 or RUFEN8? They're both Ibuprofen 600 or 800mgs. I went through the entire alphabet and 0-9 three letter combos, I found nothing RU(anything even with four or five letters/#'s)
