Brivaracetam in the treatment of focal and idiopathic generalized epilepsies and of status epilepticus

Brivaracetam is the latest approved antiepileptic drug in focal epilepsy and exhibits high affinity as SV2A-ligand. More than two thousand patients have received brivaracetam within randomized placebo-controlled trials. Significant median seizure reduction rates of 30.5% to 53.1% for 50 mg/d, 32.5% to 37.2% for 100 mg/d and 35.6% for 200 mg/d were reported. Likewise, 50% responder rates were 32.7% to 55.8% for 50 mg/d, 36% to 38.9% for 100 mg/d and 37.8% for 200 mg/d. Overall, brivaracetam is well tolerated. The main adverse events are fatigue, dizziness, and somnolence. Immediate switch from levetiracetam to brivaracetam at a conversion ratio between 10:1 to 15:1 is feasible, and might alleviate the behavioral side effects associated with levetiracetam. Brivaracetam has the potential to perform as an important, possibly broad-spectrum AED, initially in patients with drug-refractory epilepsies. Its intravenous formulation may be a new and desirable alternative for status epilepticus, but there is so far no experience in these patients.     

Treatment of overactive bladder with once-daily extended-release tolterodine or oxybutynin: the antimuscarinic clinical effectiveness trial (ACET)

Treatment with the antimuscarinic agents tolterodine and oxybutynin is the mainstay of therapy for overactive bladder, a chronic and debilitating condition characterized by urinary urgency with or without urge incontinence, usually in combination with urinary frequency and nocturia. This study consisted of two trials; in one, patients with overactive bladder were randomized to 8 weeks of open-label treatment with either 2 mg or 4 mg of once-daily extended-release tolterodine (TER), and in the other to 5 mg or 10 mg of extended-release oxybutynin (OER). The study protocol and design were identical for the two trials and site selection ensured that there was no bias in either trial for the tendency of investigators to prescribe one drug rather than the other, or for geographical location. A total of 1289 patients were enrolled, 669 in the tolterodine trial (TER 2 mg, n = 333; TER 4 mg, n = 336) and 620 in the oxybutynin trial (OER 5 mg, n = 313; OER 10 mg, n = 307). Fewer patients prematurely withdrew from the trial in the TER 4 mg group (12%) than either the OER 5 mg (19%; p = 0.01) or OER 10 mg groups (21%; p = 0.002). More patients in the OER 10 mg group than the TER 4 mg group withdrew because of poor tolerability (13% vs 6%; p = 0.001). After 8 weeks, 70% of patients in the TER 4 mg group perceived an improved bladder condition, compared with 60% in the TER 2 mg group, 59% in the OER 5 mg group and 60% in the OER 10 mg group (all p < 0.01 vs TER 4 mg). Response to therapy was greater in a subgroup of patients whose perception of bladder condition was moderate to severe at baseline (TER 4 mg 77% vs OER 10 mg 65%; p < 0.01). Dry mouth was dose-dependent with both agents, although differences between doses only reached statistical significance in the oxybutynin trial (OER 5 mg vs OER 10 mg; p = 0.05). Patients treated with TER 4 mg reported a significantly lower severity of dry mouth compared with OER 10 mg. In conclusion, the greater efficacy and tolerability of tolterodine ER 4 mg suggests improved clinical effectiveness compared with oxybutynin ER 10 mg.     

Comparison of 1 mg/body and 3 mg/body of intravenous granisetron for the prevention of chemotherapy-induced nausea and vomiting and adverse events in hematological malignancy patients

Granisetron is a selective 5-hydroxy tryptamine3 receptor antagonist and widely used for chemotherapy-induced nausea and vomiting (CINV). Recommended dose of intravenous granisetron in the USA and Europe has been set at 0.01 mg/kg (1 mg/body) in the antiemetic treatment guidelines established by the American Society of Clinical Oncology and National Comprehension Cancer Network. In contrast, the approved dose in Japan is 0.04 mg/kg (3 mg/body). Randomized controlled trials (RCTs) which compared 1 mg/body with 3 mg/body of intravenous granisetron for CINV had been reported in Japan. In these RCTs, however, hematological malignancy patients were excluded. We performed observational retrospective study to compare 1 mg/body with 3 mg/body of intravenous granisetron for the prevention of CINV and adverse events in hematological malignancy patients. Number of the patients and chemotherapy courses were 15 and 30 in the 1 mg/body group, and 15 and 27 in the 3 mg/body group, respectively. No nausea rates in the 1 and 3 mg/body group were 83% and 89% of courses, respectively. No vomiting rates in the 1 and 3 mg/body group were 97% and 100% of courses, respectively. The incidences of constipation in the 1 and 3 mg/body group were 34% and 45% of courses, respectively. Anaphylaxis and headache did not occur in both groups. Our findings suggested that 1 mg/body of intravenous granisetron can prevent from CINV in hematological malignancy patients, as well as 3 mg/body.     

Perampanel in the treatment of focal and idiopathic generalized epilepsies and of status epilepticus

Perampanel is the latest approved antiepileptic drug in focal and generalized epilepsies and has a distinct and selective mode of action on AMPA-receptors. Several thousand patients have received perampanel within randomized placebo-controlled trials, open-label extension trials and post-marketing observational studies. Significant median partial-onset seizure reduction rates of 23% for 4 mg/day, 26–31% for 8 mg/day and 18–35% for 12 mg/day were reported. Likewise 50 percent responder rates were 29% for 4 mg/day, 33–38% for 8 mg/day and 34–36% for 12 mg/day. Primary generalized tonic–clonic seizures were reduced by 76.5% (8 mg) vs 38.4% (placebo) in a recent controlled trial. Overall, perampanel is well tolerated and the main adverse events are dizziness, somnolence and fatigue. There are also anecdotal reports on use in progressive myoclonic epilepsies and status epilepticus. Perampanel will likely remain an important, possibly broad-spectrum AED with a significant market share, especially in patients with drug-refractory epilepsies.

Efficacy and safety of cerivastatin, 0.2 mg and 0.4 mg, in patients with primary hypercholesterolaemia: a multinational, randomised, double-blind study. Cerivastatin Study Group

Elevated serum cholesterol level is a key risk factor for cardiovascular morbidity and mortality. Cerivastatin is a highly effective lipid-lowering agent currently licensed at doses of 0.1, 0.2, 0.3 and 0.4 mg. This was a multicentre, randomised, double-blind, parallel-group study comparing the efficacy and safety of cerivastatin 0.4 mg/day with that of cerivastatin 0.2 mg/day in patients with primary hypercholesterolaemia. There was a six-week placebo run-in phase followed by a 24-week active treatment phase. A total of 494 patients were randomised to receive cerivastatin 0.4 mg (n = 332) or 0.2 mg (n = 162). Per-protocol (PP) analysis revealed that mean low-density lipoprotein cholesterol (LDL-C) level decreased by 38.4 +/- 0.7% from baseline in the 0.4 mg group, compared with a decrease of 31.5 +/- 0.9% in the 0.2 mg group (p < 0.0001). There was a significant gender difference in the 0.4 mg group: LDL-C decreased by 44.4 +/- 8.9% in women, compared with a decrease of 37.0 +/- 0.9% in men (p < 0.046). In the PP group as a whole, total cholesterol decreased by 26.0 +/- 0.5% from baseline in the 0.4 mg group, compared with a decrease of 21.6 +/- 0.7% in the 0.2 mg group (p < 0.0001). Both doses were well tolerated; only eight (2.4%) patients in the 0.4 mg group and five (3.1%) patients in the 0.2 mg group withdrew owing to adverse events. Cerivastatin 0.2 mg/day and 0.4 mg/day was found to lower low-density lipoprotein cholesterol and total cholesterol levels in a dose-dependent manner, with both doses exhibiting a good safety profile.

The absolute bioavailability and dose proportionality of intravenous and oral dosage regimens of recainam

Recainam is a novel class I antiarrhythmic agent with electrophysiologic characteristics of all three subclasses. The authors evaluated the absolute bioavailability and dose proportionality of three oral doses and two 2-stage intravenous (IV) infusion doses. Single oral doses of 200, 400, and 800 mg and IV infusions consisting of 0.8 mg/kg/5 min + 1.2 mg/kg/hr (3.75 mg/kg) and 1.6 mg/kg/5 min + 1.2 mg/kg/hr for 4 hours and 55 minutes (7.50 mg/kg) were administered to 15 healthy men. Plasma and urine samples were collected during the 36-hour period after drug administration and analyzed for recainam concentrations by HPLC. No significant differences were found in any of the pharmacokinetic parameters between the two IV dosage regimens. The absolute bioavailability of orally administered recainam increased from 73% for the 200 mg dose to 81% and 84% for the 400 and 800 mg doses, respectively. Dose proportionality deviated from linearity by 13% for the 200 vs. 400 mg doses, and 10% for the 400 vs. 800 mg doses. The slight deviation from linearity was apparently caused by increased absorption at the higher oral doses. The slight disproportionality in the disposition of recainam is not expected to be clinically significant.     

Cardiovascular protective properties of kiwifruit extracts in vitro

It is currently accepted that the consumption of fruit-derived antioxidants such as vitamin C, carotenoids, and flavonoids provides a preventive effect against cardiovascular disease. The purpose of the present study was to investigate potential cardiovascular protective properties of aqueous and 70% ethanol extracts from kiwifruit by analyzing the antioxidative, antihypertensive, hypocholesterolemic, and fibrinolytic activities in vitro. Aqueous and 70% ethanol extracts at 50 mg/ml showed DPPH-radical scavenging activities of 72.31% and 70.75%, respectively. Total antioxidant activity in linoleic acid emulsion was 85-88% at 10 mg/ml and 96-98% at 50 mg/ml of kiwifruit extract. Inhibitory activities against angiogensin I-converting enzyme of kiwifruit extracts were 21-26% at 10 mg/ml and 46-49% at 50 mg/ml, and inhibitory activities on HMG-CoA reductase were 13-14% at 10 mg/ml and 19-30% at 50 mg/ml. Fibrinolytic activity of kiwifruit was also observed at a high concentration of 100 mg/ml in both aqueous and 70% EtOH extracts. Based on our results, kiwifruit have potential cardiovascular protective properties in vitro.
