This paper reports on the results of a prospective double-blind crossover study, comparing adrenaline 1% with adrenaline 0.5% combined with guanethedine 1% over an 8-week period with each formulation. The guanethedine/adrenaline formulation was found to be the more effective hypotensive agent of the two. This study confirms the potentiating effect of adding guanethedine to adrenaline, and suggests that this combination would be a useful alternative treatment when adrenaline 1% or adrenaline 0.25% with guanethedine 1% is insufficient.
本文报告了一项前瞻性双盲交叉研究的结果,在为期8周的时间里,将1%肾上腺素与0.5%肾上腺素联合1%胍乙啶的两种配方进行比较。结果发现,胍乙啶/肾上腺素配方是两者中更有效的降压药。本研究证实了在肾上腺素中添加胍乙啶的增效作用,并表明当1%肾上腺素或0.25%肾上腺素与1%胍乙啶疗效不足时,这种联合用药将是一种有用的替代治疗方法。
