Duromine is a weight loss
pill which works by directly affecting the area of the brain that controls your appetite making you feel less hungry.This releases substances which are powerful cardiac stimulants which results in increased heart rate
, elevated blood pressure, restlessness
etc.I suggest you to consult your physician for evaluation of chest pain.Beta blocker
are used for the management of elevated blood pressure and angina(chest pain).
Hope this helps.Take care.
