Fleroxacin (FLRX), a new quinolone oral antibacterial agent, was studied in the field of obstetrics and gynecology, and the following results were obtained. 1. Clinical efficacy was evaluated in 105 patients (intrauterine infection 38, adnexitis 28, extragenital organ infection 29, others 10), with an exclusion of 9 patients out of a total of 114 patients. FLRX was orally administered at 200 mg or 300 mg once daily. 2. Clinical efficacy rates were 37/38 (97.4%) in intrauterine infection, 26/28 (92.9%) in adnexitis, 29/29 (100%) in extragenital organ infection and 10/10 (100%) in others. 3. Efficacy rates classified by isolated organisms were 23/23 (100%) in single infections by Gram-positive organisms, 11/13 (84.6%) in those by Gram-negative organisms, 8/9 (88.9%) in those by anaerobic organisms and 15/19 (78.9%) in mixed infections. 4. Side effects were observed in 4 cases (3.5%); gastrointestinal disorder with diarrhea and diarrhea in 1 patient each and insomnia in 2 patients. In laboratory examination, eosinophilia and elevation of GOT and GPT were noted in 1 patient each (1.9%). Based on the above results, we consider that FLRX is a useful drug for the obstetrical and gynecological infections.

A randomized double-blind study was performed to compare the side effects of long-term chemoprophylaxis of malaria with Fansidar (1 tablet a week) with those of a 300-mg weekly chloroquine regimen. This study was designed as a field trial with Austrian industrial workers in Nigeria and included 173 volunteers, 86 taking Fansidar and 87 taking chloroquine for 6 to 22 months. Only a few complaints were reported during that time, gastrointestinal disorders predominating in the Fansidar group and insomnia in the chloroquine group (3 cases each). The other complaints in both groups included one case each of skin rash and of visual disturbance, as well as one case of facial erythema after alcohol consumption in the Fansidar group and one of hair loss in the chloroquine group. Laboratory checks were performed at 3-monthly intervals, and included white and red cell counts, platelet counts and determination of GOT, GPT and alkaline phosphatase. There were no signs of drug-associated liver damage. In the Fansidar group there occurred a slight and transient decrease in the red cell count and in the chloroquine group a slight and transient decrease in the white cell count. Although statistically significant, these changes were without clinical significance. It is noteworthy that there were no cases of leucopenia in the Fansidar group. With the exception of one volunteer, who had discontinued his prophylactic drug regimen, malaria did not occur. Antibodies against blood stage parasites as determined by the indirect immunofluorescence test (IIFT), however, could be found at different stages of the study, which indicates that these two antimalarials are not causal prophylactic agents.

Statins are regarded as a well-tolerated class of drugs, particularly when compared with some of the older lipid-modifying agents, which have poor rates of compliance. Despite some early concern, the incidence of lens opacities observed in clinical studies involving statin use is no different from that in a normal ageing population. Similarly, the occurrence of insomnia with lipophilic agents appears to have been overemphasised and is not a clinically significant problem, irrespective of the statin under study. Fluvastatin is the newest representative of this class of agents; it has already been evaluated in thousands of patients who have hyperlipidaemia with and without additional risk factors. In controlled clinical studies, the incidence of the majority of adverse events observed with fluvastatin therapy is no higher than that seen with placebo, with the exception of gastrointestinal disturbances (known to be common to all stains). Nonetheless, the incidence of these effects seen with fluvastatin treatment is noted to be lower than that associated with cholestyramine or fibrate use. Elevations in levels of liver transaminases (aspartate aminotransferase and alanine aminotransferase) have been reported with fluvastatin therapy but have led to discontinuation of treatment with the same frequency as with placebo. Elevations in creatine kinase levels as a cause of discontinuing fluvastatin are not more frequent than with placebo. Drug-related myopathy and rhabdomyolysis have not been reported with fluvastatin therapy, and myalgia does not occur more frequently than with placebo. In terms of drug interactions, fluvastatin does not interfere with the efficacy of antihypertensive agents. In controlled clinical trials, the overall reported discontinuation rate due to adverse events noted with fluvastatin therapy is not significantly distinguishable from the rate associated with placebo.

The clinical trial development programme of mirtazapine (Org 3770), performed in Europe and the United States, demonstrated an outstanding safety profile of this compound. The evaluation of the safety was based on data from all patients who took at least one dose of study medication during studies comparing mirtazapine with placebo, amitriptyline or other active comparators. A general indication of mirtazapine's safety is the significantly lower percentage of patients (65%) who complained of any adverse clinical experiences compared with the placebo- (76%) or amitriptyline-treated group (87%). Moreover, drop-out rates due to adverse clinical experiences were significantly lower than in the amitriptyline-treatment group. Mirtazapine has virtually no anticholinergic, adrenergic or typical selective serotonin reuptake inhibitor (SSRI) side effects. The only significantly higher incidences versus placebo were seen in the adverse clinical effects of drowsiness (23% versus 14%), excessive sedation (19% versus 5%), dry mouth (25% versus 16%), increased appetite (11% versus 2%) and weight increase (10% versus 1%). These complaints were typically mild and transient in nature, and decreased over time despite increased doses of mirtazapine. In contrast, significantly higher incidences of headache (5% versus 10%) and weight decrease (2% versus 6%), symptoms commonly seen in depressed patients, were recorded in the placebo-treated patients. Also, typical SSRI adverse events, such as nausea, vomiting, diarrhoea and insomnia, and symptoms of sexual dysfunction were registered less frequently in mirtazapine-treated patients than in the placebo-treated patients. Approximately 10% of the mirtazapine-treated patients in the clinical trial programme were older than 65 years. The pattern of adverse clinical experiences seen in this group of patients is fully in line with that seen in the overall patient population. The analysis of vital sign indices, i.e. blood pressure and heart rate, showed that no changes occurred with mirtazapine treatment; this pattern was fully comparable to that seen with placebo. Furthermore, very low incidences of clinically relevant changes in laboratory indices, such as the liver enzymes alanine aminotransferase and aspartate aminotransferase or neutropenia, were recorded in each treatment group. Mirtazapine has a very low seizure-inducing potential: only one case was recorded in a patient with a history of seizures during previous treatment with clomipramine. The low seizure-inducing potential combined with a lack of cardiotoxic properties allows safety in an overdose of mirtazapine, even in elderly patients. The only symptom seen in the patients taking an overdose of mirtazapine alone or in combination with other drugs was excessive but transient somnolence, which resolved spontaneously within a few hours. In conclusion, the new antidepressant mirtazapine offers clinicians a unique combination of strong efficacy and good safety.

Benign recurrent intrahepatic cholestasis (BRIC or Summerskill-Walshe-Tygstrup-syndrome) is a rare autosomal recessive form of liver disease, which usually becomes manifest in childhood. Characteristic are recurrent episodes of jaundice and itching of different duration. Number and duration of episodic attack and asymptomatic period develop individually. For diagnosis of BRIC following criteria are proposed: At least three episodes of severe jaundice and pruritus with biochemical evidence of cholestasis, normal intra-and extrahepatic bile ducts on cholangiography, absence of a factor known to produce intrahepatic cholestasis and symptom-free intervals of several months or years. Often the diagnosis of BRIC is made very late and patients have to suffer invasive investigations (explorative laparotomy). Because of the unknown pathophysiological mechanism there is no specific treatment. We report on a 53-year-old patient with jaundice, severe pruritus, vomiting, loss of hair and weight, extreme sleeplessness and intractable cough. At the onset of the attack an increase of serum bilirubin concentration and serum alkaline phosphatase was observed, whereas aspartate and alanine aminotransferase and gamma-glutamyltransferase were normal. Histological findings of liver biopsy revealed accumulation of bile plugs in bile canaliculi. The long-term follow-up of our patient confirms that the prognosis is good.

A multi-center trial of exemestane 25 mg, an oral aromatase irreversible inactivator, was conducted to evaluate its efficacy and safety in 33 postmenopausal patients, and to investigate the pharmacokinetics/serum hormone levels in 16 postmenopausal patients, respectively, with breast cancer and anti-estrogen resistance. Exemestane 25 mg was given once daily for up to 48 weeks (maximum). The objective of this study was to confirm the reproducibility of the results shown in two studies in other countries with similar patients, to investigate the possibility of extrapolating the overseas data to Japanese. The response rate (CR + PR) was 24.2% (8.33%), which exceeded the minimum number (6 cases) required to evaluate efficacy. The response rate in this study was very similar to that observed in the two international open studies. Adverse events (subjective/objective symptoms), in which a causal relationship with exemestane administration could not be excluded, were observed in 26 cases (78.8%). Of these, hot flushes, increased sweating, fatigue, and insomnia occurred in more than 10% of patients, which was similar to that observed in the two international open studies. Abnormal laboratory results occurring in more than 10% of patients, in which a causal relationship with exemestane administration could not be excluded, were as follows: lymphocyte count decrease, alkaline phosphate increase, GOT increase, GPT increase, gamma-GTP increase, triglyceride increase, and inorganic phosphate increase, most of which were either grade 1 or 2. A remarkable decrease in serum hormone concentration was observed only for estrogen. The values of AUC0-infinity at day 1 and AUC0-24 h at day 29 (steady state) were similar, suggesting no accumulative effect of exemestane. These results demonstrate the anti-tumor effect and safety of exemestane in postmenopausal anti-estrogen resistant breast cancer patients. The reproducibility of the results of the two foreign studies was verified in Japanese patients, and it is concluded that the foreign trial data on exemestane can be extrapolated to Japanese.

A 74-year-old man with depressive symptoms was admitted to a psychiatric hospital due to insomnia, loss of appetite, exhaustion, and agitation. Medical treatment was initiated at a daily dose of 20 mg paroxetine and 1.2 mg alprazolam. On the 10th day of paroxetine and alprazolam treatment, the patient exhibited marked psychomotor retardation, disorientation, and severe muscle rigidity with tremors. The patient had a fever (38.2 degrees C), fluctuating blood pressure (between 165/90 and 130/70 mg mm Hg), and severe extrapyramidal symptoms. Laboratory tests showed an elevation of creatine phosphokinase (2218 IU/L), aspartate aminotransferase (134 IU/L), alanine aminotransferase (78 IU/L), and BUN (27.9 mg/ml) levels. The patient received bromocriptine and diazepam to treat his symptoms. 7 days later, the fever disappeared and the patient's serum CPK levels were normalized (175 IU/L). This patient presented with symptoms of neuroleptic malignant syndrome (NMS), thus demonstrating that NMS-like symptoms can occur after combined paroxetine and alprazolam treatment. The adverse drug reaction score obtained by the Naranjo algorithm was 6 in our case, indicating a probable relationship between the patient's NMS-like adverse symptoms and the combined treatment used in this case. The involvement of physiologic and environmental aspects specific to this patient was suspected. Several risk factors for NMS should be noted in elderly depressive patients whose symptoms often include dehydration, agitation, malnutrition, and exhaustion. Careful therapeutic intervention is necessary in cases involving elderly patients who suffer from depression.

The purpose of this report is to describe the overall safety profile of both short- and longer-term duloxetine treatment of fibromyalgia. Data from four double-blind, randomized, placebo-controlled studies (two with 6-month open-label extension phases) and a 1-year, open-label safety study were included. Safety measures included treatment-emergent adverse events (TEAEs), adverse events leading to discontinuation, serious adverse events (SAEs), clinical laboratory tests, vital signs, and electrocardiograms. The most common TEAEs for short-term treatment with duloxetine were nausea (29.3%), headache (20.0%), dry mouth (18.2%), insomnia (14.5%), fatigue (13.5%), constipation (14.5%), diarrhea (11.6%), and dizziness (11.0%; all p < 0.05 vs. placebo). Most TEAEs emerged early and were mild to moderate in severity. The profile of adverse events in patients enrolled at least 6 months, and for patients in the 1-year study, was similar to that found in the short-term treatment studies, with no new adverse events emerging at a notable rate. About 20% of patients discontinued due to adverse events in the short-term treatment studies and in the 1-year study. SAEs were uncommon, and none occurred at a significantly higher frequency for duloxetine compared with placebo. Mean changes in vital signs and weight were small. Rates of treatment-emergent potentially clinically significant (PCS) vital sign, laboratory, and electrocardiogram measures were low, with only PCS rates of alanine aminotransferase being significantly higher for duloxetine compared with placebo in the placebo-controlled treatment studies. In the 1-year study, four patients (1.1%) had suicide-related behavior. The data provided here summarize short- and long-term safety from five clinical studies in patients treated with duloxetine for fibromyalgia. In addition, postmarketing surveillance continues for adverse events reported with duloxetine in fibromyalgia, as in other indications.

Levofloxacin (LVFX), a fluoroquinolone agent, has a broad spectrum that covers Gram-positive and -negative bacteria and atypical pathogens. It demonstrates good clinical efficacy in the treatment of various infections, including lower respiratory tract infections (LRTIs) and urinary tract infections (UTIs). To evaluate the efficacy and safety of oral LVFX 500 mg once daily, a large open-label clinical trial was conducted in 1266 patients (899 with LRTIs and 367 with UTIs) at 32 centers in China. In the per-protocol population, the clinical efficacy rate (cure or improvement) at 7 to 14 days after the end of treatment was 96.4% (666/691) for LRTIs and 95.7% (267/279) for UTIs. In 53 patients diagnosed with atypical pneumonia the treatment was effective. The bacteriological efficacy rate was 96.6% (256/265) for LRTIs and 93.3% (126/135) for UTIs. The eradication rate of the causative pathogens was 100% (33/33) for Haemophilus influenzae and 96.0% (24/25) for Streptococcus pneumoniae in LRTIs, and 94.1% (80/85) for Escherichia coli in UTIs. The overall efficacy rates were 89.3% (617/691) for LRTIs and 87.8% (245/279) for UTIs. The incidence of drug-related adverse events (ADRs) was 17.3% (215/1245), and the incidence of drug-related laboratory abnormalities was 15.7% (191/1213). Common ADRs were dizziness, nausea, and insomnia. Common laboratory abnormalities included "WBC decreased", "alanine aminotransferase (ALT) increased", "aspartate aminotransferase (AST) increased", and "lactate dehydrogenase (LDH) increased". All of these events were mentioned in the package inserts of fluoroquinolones including LVFX, and most events were mild and transient. Thirty-four patients (2.7%) were withdrawn from the study because of the ADRs. No new ADRs were found. This study concluded that the dosage regimen of LVFX 500 mg once daily was effective and tolerable for the treatment of LRTIs and UTIs.
