Antibiotics: If someone has a history of psoriasis, the doctor will most likely take a throat culture when that individual has a sore throat. If the culture results are positive (meaning that the individual has a streptococcal infection), then starting immediately on antibiotics for the infection is very helpful.
A: Metoprolol (Lopressor, Toprol XL) is classified in a class of drugs called beta-blockers. Beta-blockers are used to treat angina (chest pain) and hypertension (high blood pressure). Beta-blockers are also used to treat or prevent heart attack.
Cardioselective beta-blockers, such as acebutolol, atenolol, betaxolol, bisoprolol, esmolol, and metoprolol, would not be expected to cause hypertensive reactions following a systemic dose of epinephrine. This is because cardioselective beta-blockers have little effect on the beta-adrenergic receptors in the arterioles.
