The effect of lactitol, a new non-absorbable disaccharide, in the treatment of chronic hepatic encephalopathy was assessed in 14 cirrhotic patients with non-selective portosystemic anastomosis in a randomized, cross-over study. At the time of inclusion, all patients showed alterations in mental state, and/or psychometric performance, and in the electroencephalogram. Moreover, 10 out of 14 patients suffered from recurrent episodes of hepatic encephalopathy in the 12 months prior to the study. Patients were randomly treated for two consecutive periods of six months with either lactitol or lactulose. The PSE index was calculated to quantify the neuro-psychiatric impairment. Twelve patients completed the study. The patients required a daily dose of 38.2 g +/- 19 of lactulose or 36.3 g +/- 5 of lactitol to produce two semi-soft stools per day. No deterioration in the mental state or in the other neuro-psychiatric parameters were observed, neither during lactitol nor during lactulose therapy. During the study, mild episodes of recurrent encephalopathy occurred in 60% of the patients taking lactulose, and in 25% of the patients taking lactitol, the difference not being significant (X = 1.54, p = 0.21). Flatulence, the major side-effect noted during the study, was present in 7 of the 12 patients during lactulose treatment, and in 2 patients during lactitol treatment; one patient on lactitol complained of nausea. The side effects which occurred during lactitol of the dosage, while those occurring during lactitol appeared when the dosage was higher than 40 g. Lactitol may be considered at least as effective as lactulose in the treatment of chronic hepatic encephalopathy.

A need exists for safe, effective therapy for the relief of the symptoms of allergic rhinitis (AR) that also consistently relieves nasal congestion, the most common and bothersome symptom. This study was performed to assess efficacy and safety of a once-daily tablet containing 10 mg of loratadine, an antihistamine, and 10 mg of montelukast, a leukotriene antagonist (SCH 445761) versus placebo and pseudoephedrine (PSE; 240 mg once-daily formulation; active comparator). In a multicenter, parallel-group, double-blind, double-dummy, randomized study, 1095 subjects with documented history of seasonal AR and positive skin-prick test to a prevailing aeroallergen were treated for 15 days with fixed-dose combination loratadine/montelukast (L/M), PSE, or placebo. After randomization, subjects rated severity of nasal congestion and measured peak nasal inspiratory flow (PNIF) rate in the morning and evening. The change in quality of life from baseline was also assessed. L/M and PSE were significantly more effective than placebo in alleviating nighttime and daytime nasal congestion and improving PNIF rate, an objective measure of nasal obstruction. There were no significant differences between L/M and PSE for any efficacy analysis including improvement in the quality of life. Subjects treated with L/M experienced a similar incidence of total adverse events versus placebo and a lower incidence of total adverse events (including dizziness, insomnia, jitteriness, nausea, and dry mouth) versus PSE. Nasal decongestant activity of L/M was significantly higher than that of placebo and similar to that of PSE in symptomatic AR subjects. L/M showed a safety profile similar to placebo and was better tolerated than PSE. Thus, L/M offers a safe and efficacious alternative to PSE for the treatment of nasal congestion associated with AR.
