Compound Robitussin Tablets is a compound preparation containing a variety of ingredients such as Chinese and Western medicines, including Robitussin, Wild Chrysanthemum, Hanfangji, Hydrazin, Librium and other drugs. Although compound rooibos tablets have the effect of lowering blood pressure, but this drug does not belong to the first line of clinical blood pressure drugs, it is recommended that patients with hypertension should not prefer compound rooibos tablets for long-term antihypertensive treatment. There is a lack of evidence-based clinical support for antihypertensive treatment with compound rooibos tablets, and the effectiveness of long-term antihypertensive therapy and the existence of long-term adverse effects are not clear. Patients with hypertension should use clinical first-line antihypertensive drugs, such as diuretics, beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists. Rational selection is made according to the patient’s specific situation for long-term antihypertensive therapy.
