Betalucil is the trade name for Metoprolol Tartrate. In principle, olmesartan ester tablets and metoprolol tartrate can be taken at the same time, but whether they need to be taken at the same time needs to follow the doctor’s advice. Olmesartan ester tablets are angiotensin II receptor antagonists. It can be used for the treatment of hypertension, but may cause allergy, gastrointestinal reactions, hypotension, tachycardia and other adverse reactions, allergy to this drug, bilateral renal artery stenosis, uremia and other patients are prohibited. Metoprolol tartrate reduces heart rate, decreases cardiac output and lowers blood pressure by blocking β1-receptor agents, but may cause adverse reactions such as low blood pressure and bradycardia, and is contraindicated in patients with allergy to this drug, cardiogenic shock, sick sinus node syndrome, and bradycardia. In principle, the combination of the two drugs can play a synergistic role in lowering blood pressure, but there is a risk of low blood pressure, so whether you need to take at the same time still need to be judged by the doctor according to individual circumstances. Be sure to take the medication under the guidance of a doctor, and regularly review blood pressure, heart rate and other items.
