Key result
Levamlodipine plus bisoprolol lowers BP and limits organ damage versus monotherapy in hypertensive rats.
Why the study?
Hypertension is a major risk factor for stroke, and the synergic effects of levamlodipine and bisoprolol on blood pressure reduction and organ protection were studied in spontaneously hypertensive rats.
Does the combination of levamlodipine and bisoprolol reduce blood pressure and provide organ protection in spontaneously hypertensive rats?
Does the combination of levamlodipine and bisoprolol reduce blood pressure and provide organ protection in spontaneously hypertensive rats?
The combination of levamlodipine and bisoprolol provides synergistic blood pressure reduction and organ protection in a hypertensive rat model while mitigating individual heart rate side effects.

Supports synergistic effects in SHR models; leaves open clinical translation for hypertension-related stroke prevention.
AIMS: Stroke is a major cause of disability and death worldwide. Hypertension is one of the most important risk factors for stroke. The objective of this work was to study the synergic effects of levamlodipine and bisoprolol on blood pressure reduction and organ protection in spontaneously hypertensive rats (SHR). METHODS: Blood pressure was continuously monitored in conscious SHR. For acute study, a single dose of drugs was administrated via an intragastric catheter. For chronic study (4 months), drugs were delivered via rat chow. RESULTS: A single dose of levamlodipine (from 1 mg/kg), bisoprolol (from 0.125 mg/kg), and their combinations significantly decreased blood pressure. The levamlodipine-induced tachycardia and the bisoprolol-induced bradycardia were temporized by the combination of these two drugs. Upon chronic treatment, this combination also decreased blood pressure variability and reduced organ damage. CONCLUSION: Levamlodipine and bisoprolol produce synergic effects on blood pressure reduction and organ protection in SHR.

Yang et al. (2012) studied Hypertension. Levamlodipine and bisoprolol combination was evaluated on Blood pressure reduction and organ protection. The combination of levamlodipine and bisoprolol significantly decreased blood pressure, temporized drug-induced heart rate changes, and reduced organ damage in spontaneously hypertensive rats.
