What is Tiazac
 Tiazac
is in a class of drugs called calcium channel blockers. Tiazac
relaxes (widens) your blood vessels (veins and arteries),
which makes it easier for your heart to pump and reduces the
workload on it.
Tiazac
is used to treat hypertension (high blood pressure), to treat
angina (chest pain), and to slow unusually fast heartbeats.
Tiazac
may also be used for purposes other than those listed in this
medication guide.
