Selected AbstractsEfficacy and safety of 800 and 1200 mg eslicarbazepine acetate as adjunctive treatment in adults with refractory partial-onset seizuresACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009A. Gil-Nagel Objectives ,,, To evaluate the efficacy and safety of eslicarbazepine acetate (ESL) as adjunctive therapy in adults with partial-onset seizures. Material and methods ,,, Double-blind, placebo-controlled, parallel-group, multicenter study consisting of an 8-week baseline period, after which patients were randomized to placebo (n = 87) or once-daily ESL 800 mg (n = 85) or 1200 mg (n = 80). Patients received half dose during 2 weeks preceding a 12-week maintenance period. Results ,,, Seizure frequency over the maintenance period was significantly (P < 0.05) lower than placebo in both ESL groups. Responder rate was 23% (placebo), 35% (800 mg), and 38% (1200 mg). Median relative reduction in seizure frequency was 17% (placebo), 38% (800 mg), and 42% (1200 mg). The most common adverse events (AEs) (>10%) were dizziness, somnolence, headache, and nausea. The majority of AEs were of mild or moderate severity. Conclusions ,,, Once-daily treatment with ESL 800 and 1200 mg was effective and generally well tolerated. [source] The efficacy of telmisartan compared with perindopril in patients with mild-to-moderate hypertensionINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 2004I. Nalbantgi Summary In this study, efficacy of the angiotensin II type 1 receptor blocker telmisartan given as monotherapy was compared with that of perindopril monotherapy in patients with mild-to-moderate hypertension. After a 2-week, single-blind, placebo run-in period, 60 patients were randomised to double-blind, once-daily treatment with telmisartan 80 mg or perindopril 4 mg for 6 weeks. Clinic and ambulatory blood pressure measurements and clinical laboratory evaluation were performed at the end of the placebo run-in and active treatment phases. Both telmisartan and perindopril significantly (p < 0.0001) reduced clinic systolic blood pressure (SBP) and diastolic blood pressure (DBP) compared with baseline values. Also, both drugs significantly (p < 0.0001) reduced 24-h mean ambulatory SBP and DBP compared with baseline. Comparison of the mean hourly antihypertensive activities showed that the reduction in mean ambulatory DBP for the last 8 h of the dosing interval was significantly greater (p < 0.05) in telmisartan-treated patients. A 24-h mean DBP of <85 mmHg was observed in 66.6% of the telmisartan-treated patients but in only 46.6% of the perindopril-treated patients (p < 0.05). It is concluded that telmisartan and perindopril both produce significant reductions in clinic SBP and DBP, but the mean reduction in ambulatory DBP during the last 8 h of the dosing interval is greater in patients treated with telmisartan. [source] Antihypertensive Efficacy of the Oral Direct Renin Inhibitor Aliskiren as Add-On Therapy in Patients Not Responding to Amlodipine MonotherapyJOURNAL OF CLINICAL HYPERTENSION, Issue 10 2007Waymon Drummond MD This study investigated the addition of the direct renin inhibitor aliskiren to amlodipine in patients with mild to moderate hypertension that was inadequately controlled with amlodipine alone. Following once-daily treatment with amlodipine 5 mg for 4 weeks, patients whose hypertension responded inadequately to therapy (mean sitting diastolic blood pressure [DBP] 90,109 mm Hg) (n=545) were randomized to 6 weeks of double-blind treatment with amlodipine 5 mg plus aliskiren 150 mg, amlodipine 5 mg, or amlodipine 10 mg. At the study's end, mean systolic blood pressure and DBP reductions with the combination of aliskiren 150 mg and amlodipine 5 mg (11.0/8.5 mm Hg) were significantly greater (P<.0001) than with amlodipine 5 mg (5.0/4.8 mm Hg),the comparator group,but similar to amlodipine 10 mg (9.6/8.0 mm Hg). All treatments were well tolerated. Edema occurred more frequently with amlodipine 10 mg (11.2%) than with combination therapy (2.1%) or amlodipine 5 mg (3.4%). In conclusion, aliskiren 150 mg plus amlodipine 5 mg shows similar but not better blood pressure-lowering efficacy when compared with amlodipine 10 mg in patients not completely responsive to amlodipine 5 mg; less edema was noted with combination therapy. [source] An investigation of dose titration with darifenacin, an M3 -selective receptor antagonistBJU INTERNATIONAL, Issue 4 2005William Steers OBJECTIVES To evaluate the efficacy, tolerability and safety of a flexible-dosing strategy with darifenacin, an M3 -selective receptor antagonist, in patients with symptoms of overactive bladder (OAB). PATIENTS AND METHODS In this multicentre double-blind 12-week study, 395 patients (aged 22,89 years; 84% female) with OAB symptoms for >6 months were randomized (2 : 1) and received once-daily treatment with darifenacin controlled-release tablets 7.5 mg (268 patients) or matching placebo (127). After 2 weeks of treatment, the efficacy, safety and tolerability were assessed and the dose increased to 15 mg once daily (pseudo-increase for placebo recipients) if additional efficacy was required by both the patient and physician. In the week before clinic visits (at 2 and 12 weeks), patients recorded incontinence episodes (primary efficacy endpoint) and several secondary efficacy variables in an electronic daily diary. Safety and tolerability were evaluated from withdrawal rates and adverse-event reports. RESULTS The treatment groups had comparable baseline characteristics. Similar proportions of darifenacin (59%) and placebo (68%) recipients increased the dose at 2 weeks; at 12 weeks patients on darifenacin (overall group) had a significantly greater reduction in the median number of incontinence episodes per week than had those on placebo, at ,,8.2 (,62.9%) and ,,6.0 (,48.1%), respectively (P = 0.035). There were also significant improvements in voiding frequency (P = 0.001), bladder capacity (volume voided; P=,0.036), frequency of urgency (P < 0.001), severity of urgency (P = 0.013) and number of significant leaks/week (i.e. incontinence episodes needing a change of clothing or pads, per week; P = 0.010) for darifenacin over placebo. Subset analysis suggested that some patients (those remaining on darifenacin 7.5 mg) were more sensitive to darifenacin than those who increased the dose, based on both efficacy and adverse events. Continued treatment with 7.5 mg for ,sensitive' patients, and an increased dose (to 15 mg) for remaining patients, resulted in comparable outcomes by 12 weeks. The most common treatment-related adverse events were mild-to-moderate dry mouth and constipation, which led to discontinuation in <,3.0% of darifenacin-treated patients and <1.0% of the placebo group. Central nervous system and cardiovascular adverse events were comparable to those with placebo. CONCLUSIONS Darifenacin appears to be an effective, well-tolerated and flexible treatment for patients with OAB, allowing individualized dosing according to patient needs. [source] Combination treatment with telmisartan and hydrochlorothiazide in black patients with mild to moderate hypertensionCLINICAL CARDIOLOGY, Issue 1 2001Janet B. Mcgill M.D. Abstract Background: Hydrochlorothiazide (HCTZ) is commonly used to treat black patients with hypertension. To avoid the metabolic disturbances associated with high-dose HCTZ, blood pressure control may be achieved by combining low doses with another antihypertensive. Hypothesis: The study was undertaken to assess the tolerability and antihypertensive dose-response efficacy of telmisartan and HCTZ and their combination in black patients with mild to moderate hypertension (mean supine blood pressure 140/95-200/114 mmHg). Methods: Following a 4,week, single-blind, placebo run-in period, 222 black patients were randomized to once-daily treatment with one of 20 different double-blind combinations of telmisartan (0, 20, 40, 80, 160 mg) and HCTZ (0, 6.25, 12.5, 25 mg) for 8 weeks. Blood pressure was measured at baseline and after 2, 4, and 8 weeks. Results: Telmisartan 80 mg/HCTZ 12.5 mg reduced supine trough diastolic blood pressure (DBP),primary efficacy parameter,by 13.3 mmHg, and supine trough systolic blood pressure (SBP) by 21.5 mmHg. These reductions represented benefits of 13.7/8.7 mmHg over telmisartan 80 mg and 12.3/8.1 mmHg over HCTZ 12.5 mg(p<0.01). Telmisartan 40 mg/HCTZ 12.5 mg reduced supine trough SBP/DBP by 14.3/10.0 mmHg, amounting to 12.3/3.3 mmHg more than telmisartan 40 mg and 5.1/4.8 mmHg more than HCTZ 12.5 mg, This reached significance for the comparisons with telmisartan 40 mg for SBP and HCTZ 12.5 mg for DBP (p,0.05). A response surface analysis and therapeutic response rates confirmed the additive antihypertensive effects of telmisartan and HCTZ. All treatments were well tolerated, with side-effect profiles comparable with placebo. Adverse events were mainly transient and of mild to moderate severity. Conclusions: Telmisartan 80 mg combined with HCTZ 12.5 mg is effective and well tolerated in black patients with mild to moderate hypertension, providing greater antihypertensive activity than the corresponding monotherapies. [source] Effects of long-term vardenafil treatment on the development of fibrotic plaques in a rat model of Peyronie's diseaseBJU INTERNATIONAL, Issue 3 2006MONICA G. FERRINI OBJECTIVES To determine whether the phosphodiesterase-5 (PDE5) inhibitor, vardenafil, given orally and in different regimens, has a similar effect to that of the PDE5 inhibitor sildenafil, which prevented the development of a Peyronie's disease (PD)-like plaque formation induced by injecting transforming growth factor ,1 (TGF-,1) into the tunica albuginea of the rat. MATERIALS AND METHODS Vardenafil was given to male rats (eight per group) either in the drinking water or as an oral instillation once daily, at ,,1 and ,,3 mg/kg/day for 45 days after one injection with TGF-,1 into the tunica albuginea, as an ,early preventive' treatment for TGF-,1-induced formation of a PD-like plaque. Other groups received the two doses of vardenafil only in the drinking water, starting with a well-formed plaque, for 42 days (,late, therapeutic' administration). Sections of penile tissue were stained histochemically or immunohistochemically, followed by quantitative image analysis for collagen/smooth muscle and collagen III/I ratios, myofibroblast content (,-smooth muscle actin), TGF-,1 expression, and apoptotic index. RESULTS Preventative treatment with vardenafil at the higher dose (both continuous and once-daily treatments) reduced the collagen/smooth muscle and collagen III/I ratios, and the numbers of myofibroblasts and TGF-,1-positive cells, and selectively increased the apoptotic index in the PD-like plaque. The lower dose was less effective, When vardenafil was given continuously in the drinking water for 41 days after the PD-like plaque was formed, there was only a partial reduction of the plaque. CONCLUSIONS Long-term oral treatment with vardenafil slows and reverses the early stages of an experimental PD-like plaque in the rat, and might ameliorate a more advanced plaque.
