Although there is some evidence for the efficacy of long-term treatment with rifaximin for symptomatic relief in patients with uncomplicated diverticular disease, an unresolved issue is whether rifaximin can prevent major inflammatory complications of diverticular disease. In the two prospective open trials discussed above, the occurrence rate of complications in 12 months was lower in patients treated with glucomannan plus rifaximin compared to patients treated with glucomannan only 2.7 versus 0.9% [43] and 3.2 versus 1.3% [44], This observation was not confirmed in the double-blind placebo-controlled trial [45] in which no difference in the 1-year complication rate was observed between the rifaximin and placebo groups. However, in all the studies, the number of patients suffering complications in a 12-month period was too small to detect any statistically significant... 

Orally disintegrating tablets - Administration with liquid is not necessary. The orally disintegrating tablet is packaged in a blister within an outer aluminum pouch. Instruct patients not to remove the blister from the outer pouch until just prior to dosing. The blister pack should then be peeled open with dry hands and the orally disintegrating tablet placed on the tongue, where it will dissolve and be swallowed with saliva. 

When the instillation of eye drops is difficult (eg, pediatric patients, adults with particularly strong blink reflex), the close-eye method may be used. This involves lying down, placing the prescribed number of drops on the eyelid in the inner corner of the eye, then opening eye so that drops will fall into the eye by gravity. 

Fig. 4.2 In Panel A, the effects of CRT on NYHA class is shown for three trials, all of which shared similar entry criteria and a 6-month randomized, double-blind study duration. In each graphic, control (no CRT) is represent in open boxes and patient treated with CRT (CRT) in hashed boxes. Panel B represents the effect of CRT on 6-min hall walk distance and Panel C represents the peak oxygen consumption on cardiopulmonary exercise testing...

Diazoxide is a potassium channel opener with a rapid antihypertensive action after intravenous administration. Diazoxide causes hyperglycaemia which may underlie side-effects such as nausea and vomiting, cardiac dysrhythmia and ketosis. Diazoxide was used occasionally in the management of hypertensive emergencies, but it is now largely abandoned for this indication. Diazoxide is an alternative for glucagons in patients with hypogycaemia. 

Children with Tourette s syndrome and ADHD refractory to other ADHD medication (n = 29) were treated openly with an average deprenyl dose of 8 mg/ day (Jankovic, 1993). The vast majority of patients (26/29) reported clinical improvement with no serious adverse outcomes. Mild side effects that did not require discontinuation of the drug were noted in six patients. Two patients had exacerbations of their tics. A later controlled trial of low-dose selegiline (10 mg/day) did not demonstrate statistically significant improvement of ADHD symptoms in children with Tourette s syndrome (Feigin et ah, 1996). 

There have been numerous trials of use of the atypical antipsychotics in patients with developmental disabilities, but most of these trials were uncontrolled open-labeled studies or case reports (Aman and Madrid, 1999). Findings were reported for 86 adults and 1 child with prominent self-injury. The reports of adults assessed clozapine (1 report) and risperidone (4 reports). Improvement was observed for a majority of participants in all of these trials. The patients presented with a multitude of conditions, ranging from nonspecific MR and associated behavior problems, to pervasive developmental disorders (including autism), to various psychiatric disorders, including schizophrenia and manic disorder. Self-injury appeared to respond to treatment regardless of concomitant condition. In the only clozapine report with a child (who had autistic disorder), a mean dose of 283 mg/day caused a transient reduction in self-injury. 

To our knowledge, there have been no reports of controlled clinical trials of valproate as a prophylactic agent in bipolar disorder. Results from a number of open trials suggest that perhaps half of patients treated with valproate experience prophylactic benefit (reviewed in Keck et al. 1992a]. A placebo-controlled, double-blind study of the efficacy of the divalproex form of valproate is under way and may provide additional information regarding the use of this drug in the maintenance therapy of bipolar disorder. 

In contrast with lithium, valproate has been associated with a good antimanic response in patients with concurrent depressive symptoms or syndromes. Calabrese and colleagues [Calabrese and Delucchi 1990 Calabrese et al. 1992, 1993a, 1993b] have reported favorable responses in patients with rapid-cycling bipolar disorder with index episodes of either mixed or pure mania who received open-label valproate alone or in combination with other psychotropic medication. For those patients who received valproate alone, 18 [95%] of 19 patients with pure mania had a moderate or better response, and 8 [80%] of 10 with mixed mania did similarly. T. W. Freeman et al. [1992] reported on 14 patients treated with valproate in a double-blind trial with lithium carbonate and found that patients responding to valproate had signifi-... 

Berridge had emphasized that inositol enters brain very poorly [W. R. Sherman 1991). We therefore considered whether it might be possible to reverse Li" side effects in patients with low-dose inositol that would not reverse Li s therapeutic effect in brain. To test whether inositol can alleviate polyuria-polydipsia in patients treated with Li, patients complaining of Li -induced polyuria-polydipsia were recruited for an open study with administration of 3 g of inositol daily for 5 days. The dose of inositol given was low, and the treatment period short because of the ethical consideration that inositol might reverse Li s therapeutic benefit in these patients. Five of 11 patients reported a dramatic improvement in polyuria-polydipsia, whereas another four showed a mild improvement. Two patients also showed reversal of Li -induced skin lesions (Bersudsky et al. 1992). 

The only current evidence to support this view is the finding that the addition of desipramine to fluoxetine was better than desipramine alone in the treatment of patients with depression (J. C. Nelson et al. 1991). Desipramine alone resulted in the expected improvement of approximately 20% at week 1 and 40% at 2 weeks in 52 patients. In patients treated with the combination of fluoxetine and desipramine, the response was greatly accelerated, and a response of 42% was seen at the first week of treatment. At the end of 4 weeks of treatment, 71 % of the 14 patients on combined treatment were in complete remission compared with only 14% of those receiving desipramine alone. This study provides some evidence of the better efficacy seen with a double action on both noradrenaline and serotonin, but firm conclusions cannot be drawn because of the open nature of the investigation. 

Several small, open-label studies have supported TCA/antipsychotic combinations in the treatment of PMD. Minter and Mandel [1979) studied 54 inpatients with PMD who were treated openly with either TCAs alone, TCAs and antipsychotic combination, antipsychotics alone, or electroconvulsive therapy [ECT] in treatment failures. Although only 3 of 11 patients treated with TCAs alone responded, 16 of 16 patients treated with the combination of a TCA and an antipsychotic responded. Interestingly, 14 of 15 patients treated with antipsychotic drugs alone also responded, which is contrary to findings in other studies [Spiker et al. 1985). Several other open-label studies have confirmed the utility of the combination treatment for PMD [Charney and Nelson 1981 Frances et al. 1981), but few controlled studies have been completed. 

An open, comparative study of 14 acutely psychotic patients treated with lorazepam alone n = 8, mean dose, 20.9 mg/day) or lorazepam plus haloperidol (mean dose, 15 mg/day mean dose, 5.2 mg/day, respectively) demonstrated a significant decrease in psychotic symptoms over 48 hours (118). Although the improvement in both groups was equal, the doses of haloperidol were low, and there was no comparative placebo group. 

Approximately 50 subjects were randomized to each group. Open lithium or VPA treatment was also used. Those patients treated with risperidone or haloperidol had a substantially greater decrease from baseline YMS scores than those on placebo (i.e., 14 for risperidone and 13 for haloperidol versus 8 points for the placebo group (p=0.009). Further, 57% of the risperidone group achieved at least a 50% decrease from the YMS baseline score, compared with 38% in the placebo group. This study demonstrates that the addition of risperidone or haloperidol produced a better response than that achieved with a mood stabilizer alone. 

According to a randomized, open comparison in 113 adults with severe falciparum malaria in Thailand, hypoglycemia seems to occur less often in patients with malaria treated with artesunate (2.4 mg/kg intravenously followed by 1.2 mg/kg 12 hours later and then by 1.2 mg/ kg/day intravenously or 12 mg/kg orally for 7 days) compared with those treated with quinine (20 mg/kg intravenously over 4 hours followed by 10 mg intravenously over 2 hours or orally tds for 7 days) (167). Artesunate and quinine had comparable efficacy, but hypoglycemia was only observed in 10% of the patients treated with artesunate whereas it occurred in 28% of those treated with quinine. 

The management of lower urinary tract symptoms suggestive of clinical symptomatic BPH remains somewhat controversial. Treatment options range from watchful waiting, for those patients wishing to delay any active therapy, to minimally invasive treatment, such as transurethral needle ablation of the prostate and transurethral microwave therapy, to surgical interventions in the form of transurethral prostatectomy or open enucleation of the prostate. Most patients present with difficulties in urination for which a variety of medical therapies are available, including synthetic 5-a-reductase inhibitors, a-blockers, and plant extracts (Boyle et al., 2000). 

The armodafinil development program was very similar to the development program previously undertaken for modafinil (or racemic API). Four double-blind and two opened-label clinical trials (1090 patients enrolled with 645 receiving active treatment with armodafinil and 445 receiving placebo) have evaluated the efficacy and safety of armodafinil for the treatment of excessive sleepiness (ES) associated with obstructive sleep apnea (OSA), shift-work disorder (SWD), and narcolepsy.24...
