The study compares a sequential test of a beta mimetic drug (ritodrine) and an alpha inhibitor (ifenoprodil) to show that the beta mimetic drug is superior in treating threatened premature labour, because it has a success rate of 90 per cent whereas the second has a success rate of 45 per cent. Ritodrine produces secondary effects in 69 per cent of cases.
该研究比较了一种β-拟似药物(利托君)和一种α-抑制剂(艾芬地尔)的序贯试验,以表明β-拟似药物在治疗先兆早产方面更具优势,因为其成功率为90%,而第二种药物的成功率为45%。利托君在69%的病例中会产生副作用。
