Artemether-lumefantrine (A-L), a new fixed-dose oral antimalarial drug, combines the fast onset of action of artemether (an artemisinin derivative) in terms of parasite clearance with the high cure rate of lumefantrine in the treatment of acute uncomplicated Plasmodium falciparum malaria. The extensive clinical trial database of A-L has allowed a comprehensive evaluation of its tolerability and safety in a total of 1869 patients (including 243 children aged 5-12 years and 368 children aged < 5 years). The most commonly reported and possibly related adverse effects following A-L therapy involved the gastro-intestinal (abdominal pain, anorexia, nausea, vomiting, diarrhoea) and central nervous (headache, dizziness) systems. Pruritus and rash were reported by < 2% of patients. More than 90% of the reported adverse events, many of which overlapped considerably with the clinical symptomatology or evolution of acute malaria, were rated mild to moderate in intensity. Compared to A-L, significantly higher incidences of vomiting and pruritus were observed with chloroquine, dizziness, nausea and vomiting with mefloquine, somnolence with pyrimethamine + sulfadoxine, and vomiting and dizziness with quinine. There were no serious or persistent neurological side-effects related to A-L administration. A-L did not lead to any clinically relevant alterations of the laboratory parameters. Serial electrocardiographic data were available for 713 patients. The frequency of QT interval prolongations was similar to or lower than that observed with chloroquine, mefloquine, or artesunate + mefloquine; these changes were considerably less frequent than with quinine or halofantrine. All patients with QT prolongation remained asymptomatic and no adverse clinical cardiac events were reported. Artemether-lumefantrine can thus be expected to show, both in children and in adults, a favourable safety profile for the treatment of acute, uncomplicated, P. falciparum malaria; it could as well be a reserve treatment option for travellers to endemic countries.

This trial was designed to study the efficacy and tolerability of azelastine in controlling symptoms of chronic idiopathic urticaria, using ebastine as validation group. Fifty-two adult patients were randomised to receive azelastine (4 mg), ebastine (10 mg) or 18 placebo for 21 days. Patients were required to visit the investigating physicians on three different occasions (days 0, 7 and 21). On each of these three study days, investigators assessed itching, wheals and erythema, based on a 4-point scale, and quality of life using a visual-analogue scale and subscale 9 of the Short Form 36 (SF-36) Health Survey. Patients entered daily assessments of itching on diary cards also using a 4-point scale. Furthermore, investigators assessed global efficacy and tolerability of the study medication on day 21 or upon premature discontinuation of the trial. Side effects and compliance were evaluated on each visit. A statistically significant reduction in itching was found for both active treatments compared with placebo. These improvements, which were statistically significant already after 1 day of treatment, continued over the course of 3 weeks. Additionally, both azelastine and ebastine were effective in improving symptoms such as wheals and erythema when compared to placebo. The quality-of-life parameters were unaffected by either treatment. Taste perversion (2 cases) and somnolence (1 case) were the only adverse drug reactions of azelastine. Ebastine, however, seemed to cause more often and more severe symptoms such as fatigue, sleepiness and asthenia. Global assessments of efficacy and tolerability performed by the investigators, also favoured azelastine. In conclusion, both azelastine and ebastine are effective and safe drugs, able to control symptoms of chronic idiopathic urticaria since the first day of treatment, and along a period of 3 weeks.

Parecoxib (parecoxib sodium) is an injectable pro drug of valdecoxib, which is a potent and selective inhibitor of cyclo-oxygenase-2. Intravenous (IV) or intramuscular (IM) parecoxib >20 mg has analgesic activity superior to that of placebo and similar to that of IV or IM ketorolac 30 or 60 mg well controlled trials in patients with postoperative dental pain (n = 304 to 457). In a well controlled trial (n = 202), IV parecoxib 20 or 40mg showed analgesic activity greater than that of placebo and IV morphine 4mg and similar to that of IV ketorolac 30 mg following gynaecological surgery Following orthopaedic surgery, the analgesic activity of IV parecoxib 20 or 40mg was similar to that of IV ketorolac 30 mg and superior to that of IV morphine 4 mg or placebo in well controlled trials (n = 175 and 208). IV parecoxib (40 mg twice daily for 7 days) produced significantly fewer gastrointestinal erosions and/or ulcers than ketorolac (15 mg 4 times a day for 5 days) in healthy volunteers in a well controlled trial; effects on upper gastrointestinal mucosa were similar for parecoxib and placebo. Parecoxib is well tolerated after dental, gynaecological or orthopaedic surgery. The most common adverse events irrespective of treatment (parecoxib, ketorolac or placebo) after dental surgery were nausea, alveolar osteitis, dizziness and headache. Nausea, abdominal pain, headache, abdominal fullness, dizziness, back pain, fever, hypoactive bowel sounds, vomiting, tachycardia, somnolence, abnor mal breath sounds and pruritus occurred in > or = 10% of parecoxib recipients after gynaecological surgery. Similar results were seen in placebo recipients.

Cetirizine is the carboxylated metabolite of hydroxyzine, and has high specific affinity for histamine H(1) receptors. Pseudoephedrine is a sympathomimetic drug that acts directly on alpha-adrenergic receptors. black triangle Cetirizine/pseudoephedrine 5/120 mg twice daily was significantly more effective than intranasal budesonide 100 microg or placebo at improving nasal obstruction, nasal patency and reducing the volume of nasal secretion, and was significantly more effective than intranasal xylometazoline 0.1% with respect to nasal secretion, during house dust mite faeces challenge in three randomised, cross- over studies among volunteers with seasonal or perennial rhinitis. The onset of action of cetirizine/pseudoephedrine was reported to be approximately 30 minutes. black triangle The bioavailability of cetirizine and pseudoephedrine is similar after administration of cetirizine/pseudoephedrine 5/120 mg bilayer tablets or coadministration of cetirizine 5 mg tablets plus pseudoephedrine sustained-release (SR) 120 mg caplets. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was significantly more effective than each drug given alone at reducing mean total symptom scores for seasonal or perennial allergic rhinitis in two randomised, double-blind, multicentre trials. In both studies, the mean proportion of days during which the five measured symptoms (nasal obstruction, sneezing, rhinorrhoea, nasal pruritus and ocular pruritus) were absent or mild was significantly greater in recipients of the cetirizine plus pseudoephedrine SR. black triangle In one study, cetirizine 5 mg plus pseudoephedrine SR 120 mg was significantly more effective at reducing nasal obstruction than either drug alone. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was well tolerated in patients with seasonal or perennial allergic rhinitis. The most common adverse events were dry mouth, insomnia, headache, somnolence, asthenia and nervousness.

This study evaluates the efficacy and side effects of a low dose of epidural morphine combined with clonidine for postoperative pain relief after lumbar disc surgery. In 36 of 51 patients who accepted the procedure, an epidural catheter was inserted (L1-L2 level). General anesthesia was induced with propofol and sufentanil, and maintained with sevoflurane in O2/N2O. After emergence from anesthesia, epidural analgesia was initiated according to two randomly assigned protocols: 1 mg of morphine with 75 microg of clonidine (Group M) or 12.5 mg of bupivacaine with 75 microg of clonidine (Group B), in 10 mL saline. Piritramide was administered during the first postoperative 24 hours using a patient-controlled analgesia device (PCA). The following parameters were recorded: piritramide consumption during the first 24 hours; pain at rest during the first postoperative hours (D0), during the first night (D1), and during the first mobilization; [visual analogue scale (VAS)]; and the occurrence of drowsiness, motor blockade, respiratory depression, nausea, vomiting, itching, micturition problems, and bladder catheterization during D0 and D1. Epidural administration of morphine-clonidine significantly improved postoperative pain relief and reduced piritramide consumption as compared to epidural bupivacaine-clonidine. Side effects did not differ between groups except for a higher incidence of micturition problems in Group M during D1. The occurrence of bladder catheterization was not significantly higher in that group. We conclude that a low dose of epidural morphine combined with clonidine offers a better postoperative analgesia than does bupivacaine-clonidine. The excellent analgesic conditions were obtained at the expense of a higher incidence of difficulties in initiating micturition.

A multicenter, open labeled, randomized early Phase II study for CGS 20267 was conducted at the doses 0.5 mg once daily and 1.0 mg once daily in postmenopausal women with advanced breast cancer. Sixty-four patients were randomly assigned to the doses of either 0.5 mg once daily (n = 33) or 1.0 mg once daily (n = 31). Thirty-one patients were eligible for 0.5 mg group, and 29 for 1.0 mg group. A total of 57 patients (30 in the 0.5 mg group and 27 in the 1.0 mg group) were eligible for the evaluation of efficacy. There were 3 CR, 5 PR, 5 stable disease (SD: NC lasting over 24 weeks), 7 NC and 10 PD in the 0.5 mg group. The objective response rate (ORR) was 26.7%. There were 4 CR, 7 PR, 8 SD, 3 NC and 5 PD in the 1.0 mg group. The ORR was 40.7%. A total of 57 patients (29 in the 0.5 mg group and 28 in the 1.0 mg group) were eligible for safety evaluation. Adverse clinical events related to CGS 20267 in the 0.5 mg group were headache, nausea, cold sweat, sleepiness and muscle ache in the lower extremities (2 patients, incidence rate 6.9%) whereas those in the 1.0 mg group were generalized itching and generalized hot feeling (2 patients, incidence rate 7.1%). All of the adverse events were grade 1 except the generalized itching which was grade 2. CGS 20267-related abnormalities in the laboratory tests for the 0.5 mg group were a decrease in WBC, and increases in GOT, GPT, LDH and gamma-GTP (5 patients, 14.3%) whereas those in the 1.0 mg group were increases in GPT, gamma-GTP, alkaline phosphatase, and total bilirubin (1 patient, 3.6%). The increases in GOT and GPT were grade 2, but others were grade 1. The data show both CGS 20267 0.5 mg once daily and 1.0 mg once daily to be effective and tolerable in the treatment of postmenopausal women with advanced breast cancer.

Patients with reflux esophagitis (grade II or III, Savary-Miller, intention-to-treat, n=256, age range 19-82 years) were randomly assigned to a double-blind, double-dummy treatment with either pantoprazole 40 mg once daily or ranitidine 150 mg twice daily. After 4 weeks, each patient was clinically and endoscopically assessed. Failure to heal required a further 4 weeks of treatment and a new evaluation thereafter. After 4 weeks, healing of lesions was confirmed in 63% (69 out of 109) of patients receiving pantoprazole and in 22% (25 out of 113) receiving ranitidine (P < 0.001, per protocol population). After 8 weeks, the cumulative healing rates were 88% and 46%, respectively (P < 0.001). Complete freedom from esophagitis-related symptoms (acid eructation, heartburn, pain while swallowing) was greater in the pantoprazole than in ranitidine group after 2 and 4 weeks (74% vs. 47%; 87% vs. 52%, respectively, P < 0.001). After 4 weeks, the healing rate was 76% in Helicobacter pylori (Hp)-positive vs. 45% in Hp-negative patients treated with pantoprazole (P < 0.01). The Hp status did not influence healing rates in patients treated with ranitidine. The most frequent adverse events in the pantoprazole group were diarrhea and somnolence (2-3% of patients), and in the ranitidine group, headache, diarrhea, dizziness, increase of liver enzymes and pruritus (2-4% of patients). In conclusion, pantoprazole was more effective than ranitidine in the healing rate and relief from reflux esophagitis-associated symptoms, and Hp infection was associated with higher healing rate during therapy with pantoprazole but not with ranitidine.

Atopic dermatitis is a common skin disease in Thai children. The treatment of atopic dermatitis requires topical corticosteroids, emollients, systemic antihistamine as well as avoidance of the precipitating factors. A double blind multicenter placebo controlled study was conducted to assess the therapeutic efficacy of topical mometasone furoate 0.1 per cent cream in combination with loratadine syrup. Forty-eight patients, 23 boys and 25 girls, mean age 73.67 months, with atopic dermatitis were included in the study. The severity of the disease was measured by using the SCORAD index including the degree of erythema, dryness, edema/papulation, oozing/crusting, lichenification, and excoriation. Total area involved was measured and a target area of dermatitis was selected for specific evaluation. The degree of clinical signs and pruritic symptom was graded. The sensation of pruritus, disturbance of sleep due to pruritus, and feeling of sleepiness in the morning were recorded. Mometasone furoate 0.1 per cent cream was applied to all patients once daily. One group received loratadine syrup and another group received placebo syrup. They were followed-up on day 5, 8 and 15. The severity of atopic dermatitis and pruritus significantly decreased after 14 days of treatment in both groups (p < 0.001). There was no difference in therapeutic response between the loratadine and placebo groups (p = 0.99). All signs examined had decreased by the end of the study. The result demonstrated that 0.1 per cent mometasone therapy is very effective for treating childhood atopic dermatitis. Loratadine did not show beneficial effect when combined with good topical corticosteroid but it was safe and had no serious side effect on the children.

This case report demonstrates the anesthetic management of a 41-year-old primiparous parturient with massive ascites due to advanced Krukenberg tumors, undergoing Cesarean section. We chose a combined intrathecal-epidural technique, using intrathecal hypobaric fentanyl and hyperbaric meperidine, and a low dose of epidural bupivacaine in order to avoid hemodynamic instability in this critically ill patient. Surgery was carried out without difficulty under adequate regional anesthesia. The blood pressure was maintained with low doses of phenylephrine and dopamine. Opioid-related complications such as nausea-vomiting, pruritus, drowsiness, and respiratory depression were not observed in this patient. Therefore, intrathecal opioids combined with a low dose of epidural local anesthetics for Cesarean section is suitable for critically ill patients with malignant abdominal tumors, such as a Krukenberg tumor, complicated by massive ascites.

The aim of our open clinical trial was to determine the efficacy and the tolerance of a blue coloured placebo in moderated anxious patients (Hamilton score below 15) and a red one for tired patients without DSM IV criteria of major depressive disorder. All the patients knew that treatment was a placebo and so, had no pharmacological effect. The trial run over seven days. All patients were considered as responders if their initial symptoms were reduced more than 50%. At the end of the week, the final clinical evaluation showed that 18 patients about 34 were in good condition (10 anxious patients, 7 women and 3 men, and 8 tired patients, 4 women and 4 men). The anxious score of Hamilton scale was reduced of 63%; 16 of the 18 responders were absolutely sure that the treatment was usefull. Four patients were obliged to stop their treatment because side effects: insomnia, tiredness and sleepiness, gastric pain and itching of fore arm.
