Clobazam in the treatment of Lennox-Gastaut syndrome.

PURPOSE: This randomized, double-blind, dose-ranging study evaluated safety and efficacy of clobazam (CLB) as adjunctive therapy for drop seizures in patients with Lennox-Gastaut syndrome (LGS). METHODS: Sixty-eight patients with LGS aged 2-26 years were administered CLB (low dose = target 0.25 mg/kg/day; high dose = target 1.0 mg/kg/day). The study consisted of 4-week baseline, 3-week titration, and 4-week maintenance periods, followed by a 3-week taper or continuation in an open-label study. Seizure frequency was recorded in a diary by the parent/caregiver throughout the study. RESULTS: Weekly drop seizure rates were significantly reduced from baseline in both the high-dose and low-dose groups; the reduction was significantly greater in the high-dose group. A significantly greater proportion of patients in the high-dose group experienced reductions in drop seizures of >or=25%, >or=50%, and >or=75% compared to the low-dose group; more patients in the high-dose group experienced a 100% reduction, but the difference was not significant. Nondrop seizures were also reduced in a dose-dependent manner. In both investigator and parent/caregiver global evaluations, patients in the high-dose group showed significantly greater improvements in overall symptoms compared to low-dose CLB. Adverse events were generally mild or moderate, and were similar between dose groups. Five serious adverse events were reported in four patients, but in no case was CLB discontinued. CONCLUSIONS: Clobazam was well tolerated and reduced drop seizure rates; high-dose CLB was more effective than low-dose CLB. Other seizure types were also reduced.

Efficacy and safety of lansoprazole in adolescents with symptomatic erosive and non-erosive gastroesophageal reflux disease.

OBJECTIVES: To assess the efficacy and safety of lansoprazole in the treatment of adolescents with symptomatic, endoscopically proven, non-erosive gastroesophageal reflux disease and erosive esophagitis. METHODS: Adolescents between 12 and 17 years of age with esophagitis were enrolled in this open-label trial and treated with lansoprazole 15 mg (non-erosive) or 30 mg (erosive) once daily for 8 weeks. If unhealed at week 8, those with erosive esophagitis were treated with an additional 4 weeks of lansoprazole 30 mg once daily. RESULTS: Lansoprazole produced a significant reduction from baseline in the median percentage of days with reflux symptoms (91 to 43% in the 64 adolescents with non-erosive disease and 85 to 16% in the 23 adolescents with erosive esophagitis, P < or = 0.001 for each comparison). At week 8, mucosal healing had occurred in 95% (21 of 22) of those with erosive esophagitis. Treatment-related adverse events were reported by 19% of patients with non-erosive and 4% of patients with erosive esophagitis. Headache (7%), abdominal pain (5%), nausea (3%) and dizziness (3%) were the most frequently reported adverse events. One patient discontinued treatment early because of dizziness and vomiting. An elevation in mean serum gastrin from baseline (59 pg/mL at pretreatment to 80 pg/mL at final visit) was observed. CONCLUSION: Lansoprazole 15 mg or 30 mg once daily reduced symptoms of gastroesophageal reflux in adolescents with non-erosive gastroesophageal reflux disease and erosive esophagitis, respectively. Lansoprazole 30 mg once daily for 8 weeks was effective in healing erosive esophagitis. Both treatment regimens were considered safe.

Flavor and taste of lansoprazole strawberry-flavored delayed-release oral suspension preferred over ranitidine peppermint-flavored oral syrup: in children aged between 5-11 years.

OBJECTIVE: To compare the flavor and taste preference of two acid-inhibitory therapies in healthy children aged between 5-11 years. METHODS: A single-site, single-blind, taste test trial was conducted in which 111 children participated after parental consent. One teaspoonful (5 mL) of lansoprazole delayed-release oral suspension (strawberry-flavored) and ranitidine oral syrup (peppermint-flavored) were provided to each child with a 10-minute break between samples. Children tasted the sample, swished it in their mouth for 10 seconds, and then expectorated the sample. Spring water and crackers were used to clear the palate between samples. After each sampling, children were observed for facial expressions and asked to rate their degree of liking of each sample based on a 5-point facial hedonic scale (5=like it very much, 1=dislike it very much). Likes, dislikes, and product preference were recorded. RESULTS: Of the 56 female and 54 male children who tasted both samples, 95% (105/110) preferred lansoprazole. Taste and flavor were the most often cited reasons for preferring lansoprazole (61 and 17 children, respectively) while three children preferred the flavor of ranitidine oral syrup. Lansoprazole received a higher mean liking rating compared with ranitidine (mean liking scores of 4.1 and 2.2, respectively). There was no significant difference in the preference for lansoprazole between age groups and gender with the degree of liking scores ranging between 3.5-4.4. Forty-two children disliked the texture of the lansoprazole oral suspension, citing the granules (31/110), thickness (7/110), or consistency/texture (4/110), specifically. CONCLUSION: After sampling both products, 95% of children preferred the flavor and taste of the strawberry-flavored lansoprazole delayed-release oral suspension compared with the peppermint-flavored ranitidine oral syrup.
