The safety and efficacy of intravenous granisetron were compared with combinations of conventional antiemetics in two single-blind, parallel-group studies which have been reported previously. In this review updated data from both studies is presented. In both studies granisetron (40 micrograms/kg) was given as a single 5-min infusion before chemotherapy with two additional doses allowed to control subsequent nausea and vomiting. All patients were naive to chemotherapy. Patients due to receive cisplatin (greater than 49 mg/m2) were randomly assigned to receive either granisetron alone or metoclopramide (3 mg/kg) plus dexamethasone (12 mg) given prophylactically followed by an 8-h infusion of metoclopramide (4 mg/kg). In the 24 h after the start of chemotherapy 70% of granisetron-treated patients and 67% of comparator group were complete responders. In patients due to receive moderately emetogenic chemotherapy, granisetron was compared with chlorpromazine (up to 200 mg/24 h) plus dexamethasone (12 mg). Twenty-four hour efficacy was significantly higher in the granisetron group with complete response in 68% of patients compared to 47% in the comparator group (P less than 0.001). A subset of 40 patients in this study were crossed over to receive the alternative antiemetic on their next cycle of chemotherapy. A significant majority of patients (32/34; 94%) preferred granisetron (P less than 0.001). Around 80% of the granisetron-treated patients in both groups required only a single prophylactic dose of granisetron. Following the first additional dose of granisetron, around 87% of patients reported symptoms to be improved or resolved. Adverse experience reporting was higher in the comparator groups with somnolence and extrapyramidal reactions representing the most common events. Headache was the most commonly reported adverse experience in granisetron-treated patients. Granisetron has proved safe and effective in controlling chemotherapy-induced emesis and is more convenient to administer than conventional antiemetics.

Cytokines are polypeptides which possess various biological properties affecting host defense function and response to disease. Two cytokines, interleukin-1 (IL-1) and tumor necrosis factor (TNF) induce fever, hypotension and inflammation when injected into animals or human subjects. In humans injected with either IL-1 or TNF, sleepiness, generalized myalgias and headache are commonly reported. Therefore, the production of IL-1 and TNF as a consequence of hemodialysis was hypothesized to explain, in part, the signs and symptoms of the dialysis patient. Laboratory studies confirmed that the activation of complement and the passage of microbial products from the dialysate into the blood compartment induces the synthesis of IL-1 and TNF. Although elevated production of IL-1 and TNF in the mononuclear cells and in the circulation of patients during and after hemodialysis have been reported, these levels have not been a consistent finding and are low compared to the amount of dialysis related symptoms. Recent studies, however, demonstrate that IL-1 and TNF have naturally occurring antagonists which specifically block the biological activities of these two cytokines. The IL-1 receptor antagonist blocks IL-1 binding to cells but has no IL-1 activity of itself. Soluble TNF receptors prevent TNF from binding to its cellular receptors and hence serve as anti-TNF mechanisms. These inhibitors are currently in clinical trials for sepsis where efficacy has been demonstrated; however, the IL-1 receptor antagonist (IL-1Ra) and soluble TNF receptors (sTNFR) are likely candidates for use in dialysis patients with symptomatic hypotension. Although levels of IL-1Ra and sTNFR are elevated in patients on HD, these levels reflect the host response to inflammation. It is unclear whether acute or chronic administration of IL-1Ra or sTNFR will be beneficial in treating some of the acute or chronic changes seen in dialysis patients.

Blood pressure and clinical status of 1,736 patients with cerebrovascular disease were observed during 12 months of treatment with nicardipine. The most common diagnoses were chronic cerebral ischemia (53.2%), transient ischemic attacks (TIA; 25.1%), and cerebral infarct (8.7%); 50.1% of patients were classed as hypertensive [systolic blood pressure (SBP) > or = 160 mm Hg or diastolic blood pressure (DBP) > or = 90 mm Hg]. Most patients (91.2%) received a daily dose of 60 mg nicardipine. Additional treatments included diuretics (37%), beta-blockers (11.5%), other antihypertensive drugs (15.8%), platelet antiaggregants (25.1%), and cardiotonic drugs (15.1%). A total of 282 patients (16.2%) were lost to follow-up, 21 (1.2%) patients withdrew due to side effects, 32 (1.8%) died, and 9 (0.5%) patients had treatment interrupted due to concomitant illness. In the hypertensive subgroup, blood pressure (SBP/DBP) was reduced from a mean baseline value of 175 +/- 22/97 +/- 14 mm Hg to 152 +/- 17/85 +/- 11 mm Hg at 3 months and 149 +/- 23/81 +/- 11 mm Hg after 12 months of treatment. The incidence of TIA or stroke among these patients was reduced from 29 cases (3.5%) during the first 3 months to 11 cases (1.54%) during months 4-12 (p < 0.01). In normotensive patients there were 18 (2.15%) cases during months 1-3 and 13 (1.55%) cases during months 4-12 (difference not significant). In the 280 patients treated with nicardipine alone, the most frequent side effects during the first month were facial flushing (6.8%), gastrointestinal problems (5%), dizziness (3.2%), headache (3.2%), drowsiness (3.2%), and hypotension (1.1%). Most of these side effects were transient.(ABSTRACT TRUNCATED AT 250 WORDS)

A review of the safety and tolerability of fluvoxamine in worldwide marketing studies involving 24,624 patients, predominantly receiving fluvoxamine treatment in uncontrolled studies in depression, has been conducted. There was a marked preponderance of female patients and patients aged between 30 and 50 years. The majority of patients were treated for 6 weeks, with the most frequent modal total daily dose being 100mg. The greatest proportion of adverse experiences occurring, by COSTART body system, affected the digestive system (24.1%), the nervous system (23.7%), and the body as a whole (15.3%). The only adverse experience with an incidence greater than 10% was nausea (15.7%), with somnolence (6.9%) and asthenia (6.2%) as the next most frequent experiences. Notably, the rates of agitation and anxiety were only 1.4 and 1.3%, respectively. The incidences of adverse experiences increased with age, and were slightly higher in females than males. 15.1% of patients discontinued treatment prematurely as a result of adverse experiences, principally nausea, dizziness, vomiting, somnolence, abdominal pain, and headache. The overall incidence of serious adverse events associated with fluvoxamine treatment was 2.5%, and the incidence of overall suicidality, including suicidal ideation, overdose, and intentional overdose as well as attempted and completed acts of suicide, was remarkably low at 0.8%.

Inhibitory effects on acute nausea and emesis, safety and usefulness of a single oral dose of Ondansetron tablet were evaluated in 3 different dose levels for comparison by telephone registration system, in patients receiving non-platinum anti-cancer drugs. A single dose of ondansetron at 4 mg, 8 mg or 12 mg was given orally at 2 hrs before the initial administration of anti-cancer drugs. The patients were observed for 24 hours after administration of anti-cancer drugs, for occurrence of nausea and emesis. Efficacy rates of inhibitory effects on nausea and emesis were 83.3% (10/12 cases) in 4 mg dose group, 78.6% (11/14 cases) in 8 mg dose group and 84.6% (11/13 cases) in 12 mg dose group, without statistically significant difference. Side effects were observed in 3 cases (headache, cold feeling and trembling in limbs, sleepiness) in 12 mg dose group, but these symptoms were not severe and disappeared after several hours or several days. No abnormality in clinical laboratory findings attributable to Ondansetron was observed. From the above, it was considered that Ondansetron was a clinically useful anti-emetic for nausea and emesis induced by non-platinum anti-cancer drugs and that 4 mg once daily was the optimal dose.

Nocturnal oxygen desaturation (NOD) is commonly seen not only in sleep apnea syndrome (SAS) but also in chronic lung disease (CLD) including chronic obstructive lung disease even without sleep apnea. However, the relationship of NOD to clinical symptoms such as morning headache, sleep deprivation due to breathlessness, and daytime sleepiness is not known. In this study, we examined by polysomnography the relationship between several NOD indexes, parameters of apnea, and subjective symptoms in 25 patients with SAS and 22 patients with CLD. In addition, the relation between daytime arterial blood gas data and NOD indexes, parameters of apnea, was examined. In the SAS group, there were no differences in any parameters of NOD and apnea between patients with subjective symptoms and those without symptoms. However, in the CLD group, symptomatic patients had significantly lower lowest SaO2, higher mean SaO2, and longer total desaturation time. In both groups, daytime PaCO2 had a significant correlation with several NOD parameters such as mean SaO2, lowest SaO2, and total desaturation time. In the SAS group, daytime PaCO2 was also correlated with the parameters of apnea. On the other hand, daytime PaO2 was significantly correlated with mean SaO2 only in the CLD group. From these data, we conclude that in patients with SAS, daytime PaCO2 is a variable that is related to the degree of NOD, and that in patients with CLD, subjective symptoms and daytime PaO2 in addition to daytime PaCO2 are associated with NOD.

We treated 23 patients with obstructive sleep apnea syndrome (OSAS) by nasal continuous positive airway pressure (NCPAP) at home, and examined the long-term compliance, clinical effects, and complications after NCPAP therapy. Nineteen patients continued and four patients discontinued the therapy during the mean observation period of 15 months, and the compliance was 83%. There was no significant difference in age, weight, and sleep data between the compliant group (C) and non-compliant group (NC). The causes of discontinuation of therapy were lack of adaptation to the apparatus (2 cases), improvement of clinical symptoms due to weight reduction (1 case), and induction of asthma attack (1 case). Disappearance of excessive daytime sleepiness, improvement of sleep quality, and disappearance of nocturia were observed in most cases, and disappearance of morning headache and improvement of sexual ability and emotional instability were also observed in several cases. Nine cases (39%) complained of discomfort due to the nasal mask and 6 cases (26%) complained of dryness of the mouth and nose, whereas 10 cases (43%) experienced no adverse effects. No serious complications were observed. These findings suggest that long-term home NCPAP is an effective and safe treatment for OSAS patients.

An awakening has taken place over the last 25 years to the science of sleep disorders. Foremost amongst these, both in the medical world and the public eye, has been Sleep Apnoea Syndrome (SAS). The prevalence is thought to be the order of 1-2%. Males are eight times more commonly affected than females, although after the menopause the gap narrows considerably. Sleep apnoea occurs in children, usually in relation to large tonsils and adenoids, but in adult life patients usually present between the age of 40 and 60 and the prevalence increases with age. Numerous apnoeas or hypopnoeas during the night's sleep result in disordered sleep architecture and unrefreshing sleep. This is usually accompanied by night-long snoring which may lead to marital discord and even complaints from neighbours. Symptoms on waking may be a headache and a feeling of not being refreshed by sleep. Sleepiness during the day can interfere with work and social activities and may produce risks to the patient and others if it occurs while operating dangerous machinery or driving. Over a longer time scale SAS results in intellectual and memory deterioration, a higher incidence of ischaemic heart disease, hypertension, polycythemia and pulmonary hypertension. Right heart failure is particularly likely if there is chronic airflow obstruction contributing to a low arterial oxygen level. Asystolic periods and tachyarrhythmias may occur during apnoeic periods. The increased mortality of SAS relates to coronary and cerebrovascular disease and arrhythmias. Sudden death occurs with greater frequency in patients with SAS, mainly at night.

Zardaverine is a newly developed selective phosphodiesterase III and IV inhibitor. This study investigates the bronchodilatory properties of zardaverine, administered by inhalation. Twelve patients with reversible bronchial obstruction (increase in forced expiratory volume in one second (change FEV1 % predicted) at least 15% after 200 micrograms salbutamol, median age 31 yrs, range 21-54 years) entered the double-blind, crossover study. Four puffs of either zardaverine (total dose 6 mg) or placebo were inhaled at 15 min intervals. Pulmonary function (specific airway conductance (sGaw) and FEV1 was measured by body plethysmography at regular intervals (5 and 12 min after each puff and, in addition, 30, 60, 120, 180 and 240 min after the last puff). Compared to placebo, sGaw and FEV1 increased significantly during the first hour of repeated inhalations, but not during the entire observation period of almost 5 h. The maximum mean difference between zardaverine and placebo for FEV1 was 0.3 l or 12% and occurred approximately 1 h after inhalation of the first puff. In seven patients FEV1 increased by > 15%. The duration of action varied considerably between patients. Three patients complained of side-effects (headache, drowsiness, vertigo, nausea), and one of these dropped out of the study due to vomiting. We conclude that inhalational administration of zardaverine has a modest and short-lasting bronchodilating activity.
