Betapace is a beta-adrenoceptor blocker, which inhibits the secretion of renin, an enzyme regulating blood pressure, potassium level and fluid balance in the body. Betapace is indicated to adolescents aged 18 and older and adult patients for prophylaxis and treatment of ventricular and supraventricular arrhythmias.

Most patients demonstrate appropriate therapeutic responses in administration of the daily Betapace dose of 160-320mg. Sometimes, the patients can be indicated with maximum doses of the antianginal drug, which vary from 460 to 640mg per day. However, if the maximum doses of Betapace are indicated, the benefits and potential risks to the patient’s health should be evaluated.
Treatment of arrhythmias requires the compliance and adherence to Betapace dosage. Due to the relatively long half-life of the drug, Betapace provides the long therapeutic benefit. Therefore, if the patient did not take an antianginal pill on time, nothing bad happens.
