We conducted a multicenter, double-blind, parallel-group study to compare the efficacy and safety of dihydroergotamine (DHE) nasal spray and placebo over 4 hours in the treatment of migraine. Of the 112 patients enrolled, 100 were included in the "intent-to-treat" efficacy analysis. The patients self-administered either 2.0 mg DHE (0.5 mg per nostril, repeated after 15 minutes) or placebo at the onset of two separate headaches and rated hourly the drugs' effects on pain severity, pain relief, nausea, and vomiting. The physicians assessed the overall effectiveness of the drugs in relieving headache pain, nausea, and vomiting. Both the patients' and physicians' ratings indicated that DHE was significantly superior to placebo in improving headache and nausea; according to the patients' ratings, these between-group differences were already significant at the first (hour 1) evaluation. There were no significant differential treatment effects with respect to relief of vomiting. Most adverse events were mild or moderate, confined to the nasopharyngeal area, and probably related to the route of administration. We conclude that DHE nasal spray is a safe and effective treatment for the pain and nausea of migraine attacks.
Both isometheptene mucate, dichloralphenazone with acetaminophen and sumatriptan succinate are safe and effective when used early in the treatment of an acute migraine. Several parameters suggest that isometheptene mucate, dichloralphenazone with acetaminophen may have a slight advantage compared with sumatriptan succinate in the early treatment of mild-to-moderate migraine.
The cholesterol-lowering effects of a fiber supplement were evaluated in patients with mild to moderate hypercholesterolemia. After a 9-wk diet stabilization period, patients were randomly assigned to treatment with 10 or 20 g/d of the fiber supplement or with a matching placebo. Among patients who completed the 15-wk treatment period, total cholesterol, LDL cholesterol, and the ratio of LDL to HDL (LDL/HDL) were significantly reduced (P < 0.05) for the 10- (n = 40) and 20-g/d (n = 39) groups compared with the placebo group (n = 48). In the placebo group and 10- and 20-g/d groups, the percent changes in total cholesterol were 0.4%, -5.8%, and -4.9%, in LDL cholesterol were -0.4%, -8.1%, and -7.3%, and in LDL/HDL were 1.0%, -5.6%, and -8.7%, respectively. The fiber supplement had no significant effects (P > 0.05) on HDL cholesterol or triglycerides. The changes in lipoprotein concentrations could not be attributed to changes in diet or body weight because there were no significant changes in these variables during the 15-wk treatment period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
