The inhibitory effects of GG032X tablets, a new dosage form (fast dispersing tablet) of ondansetron, 5-HT2 receptor antagonist, on nausea and emesis induced by cisplatin (CDDP), were investigated along with safety and usefulness. Subjects were chemotherapy patients starting CDDP administration for the first time, who were receiving a high single dose of CDDP (50 mg/m2 or more and intravenous drip infusion of less than 4 hours), or lower multiple doses of CDDP (a single dose of 10 mg/m2 or more, administered intravenously for 3-5 consecutive days). GG032X tablets were administered orally 1-2 hours before CDDP administration. In lower multiple doses of CDDP, GG032X tablets and CDDP were administered, as much as possible, at the same respective time when they were administered on the first day. Efficacy of GG032X tablets was evaluated in terms of inhibitory effect on nausea and emesis 24 hours after administration of a high single dose of CDDP, and of the inhibitory effect on nausea and emesis during the study period (3-5 days) in lower multiple doses of CDDP. Efficacy, safety and usefulness were evaluated in accordance with the evaluation criteria used in the clinical study of already-approved ondanstron tablets. In a high single dose of CDDP, the cases judged "effective" or better in the investigation of the inhibitory effect of the drug on nausea and emesis, accounted for 52.9% (63/119 cases). As for the overall safety rating, the cases judged as "safe" accounted for 87.0% (107/123 cases), and as a "minor safety problem" accounted for 13.0% (16/123 cases). As for the usefulness rating, the cases judged "useful" or better accounted for 52.1% (62/119 cases). Major adverse effects included headache, fever, atrial fibrillation and increases in total bilirubin, GOT and GPT values. None of these was serious, and the patients recovered without any treatment or by nosotropic therapy. Meanwhile, in lower multiple doses of CDDP, the inhibitory effect judged "effective" or better accounted for 70.6% (12/17 cases). As for the overall safety rating, all cases were judged "safe". In terms of usefulness, those cases judged "useful" or better accounted for 70.6% (12/17 cases). No adverse effect was observed. Study results of these two groups were almost the same as those for already-approved ondansetron tablets. According to the results of questionnaires for the patients who participated in the study and took GG032X tablets, the drug was found to be easy to take and had favorable results. Based on the above results, GG032X tablets were evaluated as having the same inhibitory effect as the already-approved ondansetron tablets against CDDP-induced nausea and emesis, and were considered safe and clinically useful.

To evaluate the feasibility of adjuvant chemotherapy, we analyzed the toxicities of chemotherapy for primary breast cancer in Japanese women. Since the opening of the National Cancer Center Hospital East, 180 female breast cancer patients have received adjuvant chemotherapy or chemo-hormonal therapy following surgical treatment between June 1992 and December 1995. On the basis of informed consent about prognosis and adjuvant therapy, most patients decided to choose the type of cytotoxic chemotherapy themselves. Adjuvant chemotherapy consisted of oral fluoropyrimidine compounds (OFP), cyclophosphamide + adriamycin +/- 5-fluorouracil [CA(F)] or cyclophosphamide + methotrexate + 5-fluorouracil (CMF). Toxicity was determined using the Toxicity Grading Criteria of the Japan Clinical Oncology Group (JCOG). Sixty-six patients received OFP, 59 CA(F) and the rest 55 CMF. The toxicity grading of leukocytes and neutrophils was significantly higher in patients treated with CA(F) or CMF than in those treated with OFP. Similar results were also seen relating to the toxicity of nausea/vomiting and alopecia. There was no statistical difference in the toxicity grading of hemoglobin, glutamic oxaloacetic transaminase/glutamic pyruvic transaminase (GOT/GPT) and stomatitis/ gastritis between the three groups of patients. Interestingly, the number of patients that were forced to discontinue chemotherapy was higher in those receiving OFP than in those receiving CA(F) or CMF. Cytotoxic chemotherapy of CA(F) or CMF results in greater toxicity than OFP, but is tolerated and feasible in the adjuvant setting used in Japanese breast cancer patients from the viewpoint of toxicities by anticancer chemotherapy.

Taltirelin tetrahydrate (TA-0910), novel thyrotropin-releasing hormone (TRH) analogue, was orally administered to dogs as dose levels 0.5, 5, and 50 mg/kg for 13 weeks and 0.15, 1.5 and 15 mg/kg for 52 weeks. Blood concentrations of test substance measured in 52-week study revealed that absorption of TA-0910 was with dose-dependent manner and not changed through the treatment period. These toxicokinetics suggested that there were no alterations on metabolism of TA-0910 with repeated treatment. The animals receiving 5 or 50 mg/kg showed decrease in body weight or suppression of body weight gain, and decrease in food intake (13-week study). As an abnormality in general conditions, vomiting and salivation (5 mg/kg or more, both in 13- and 52-week studies), increase in behavior as water intake (5 mg/kg or more, 13-week study), and hyperlocomotion (50 mg/kg) were observed. Elevating GPT values were noted temporally in the animals treated with 5 mg/kg or more (both in 13- and 52-week studies) without abnormal findings in histopathology. The thyroid weights were increased in treated animals receiving 5 or 50 mg/kg in 13-week study, but no histopathological changes were noted. Electron microscopy revealed dilatation of granular endoplasmic reticulums in follicular cells of thyroid from 50 mg/kg group in 13-week study. It was concluded that no-effect levels of 13- and 52-week studies were 0.5 mg/kg and 1.5 mg/kg, respectively.

A 9-year-old male German Shepherd Dog was presented with the primary complaints of vomiting, profuse watery diarrhea, anorexia, and severe weight loss. The dog developed hematemesis and melena, which were unresponsive to treatment with an H2-receptor antagonist and a gastrointestinal protectant. A marked neutrophilia, panhypoproteinemia, hypokalemia, and mildly increased activities of alkaline phosphatase and alanine aminotransferase were the only relevant abnormalities found on a CBC, serum biochemical profile, and urinalysis. An exploratory laparotomy revealed several small nonresectable masses at the root of the mesentery, which were identified histologically as a neuroendocrine neoplasm. Immunohistochemical staining of the neoplasm was positive for gastrin and negative for insulin, glucagon, pancreatic polypeptide, and vasoactive intestinal polypeptide. Fasting serum gastrin concentrations were high. Zollinger-Ellison syndrome was diagnosed, and the dog was treated with omeprazole, an H+,K(+)-ATPase inhibitor. All clinical signs resolved, and the dog remains asymptomatic 2 years later. Omeprazole may be the gastric acid antisecretory drug of choice for dogs with gastrinoma.

Azithromycin (AZM), a new oral macrolide antibiotic, in 10% fine granules or 100 mg capsules was given to pediatric patients to treat various infections. The following results were obtained in our studies of AZM for its antibacterial activities against clinical isolates, its pharmacokinetics, its efficacy, and its safety. 1. MICs of AZM, erythromycin (EM) and clarithromycin (CAM) were determined against a total of 57 strains all at 10(6) cfu/ml. Among Gram-positive cocci, MICs of AZM ranged from 0.78 to > 100 micrograms/ml against Staphylococcus aureus (20 strains), from 0.05 to 0.1 microgram/ml against Streptococcus pyogenes (11 strains), and from 0.0125 to 3.13 micrograms/ml against Streptococcus pneumoniae (10 strains). These MICs were similar to those of the other macrolides. Among Gram-negative bacilli, MICs of AZM were 0.05 micrograms/ml against Moraxella subgenus Branhamella catarrhalis (1 strain), from 0.78 to 3.13 micrograms/ml against Haemophilus influenzae (9 strains), 0.78 micrograms/ml against Haemophilus parainfluenzae (1 strain) and 6.25 micrograms/ml against salmonella sp. (1 strain). These values were similar to or lower than those of the other macrolides. Against Mycoplasma pneumoniae, MICs of AZM were < or = 0.0008 micrograms/ml in three strains. One strain of M. pneumoniae showed tolerance to AZM at MIC 25 micrograms/ml. The other agents exhibited higher MIC than AZM against this organism. 2. Plasma samples were collected from five patients receiving fine granules and four patients receiving capsules for drug level determination. The patients received AZM at 10.0 approximately 16.3 mg/kg body weight once daily for 3 days. Drug concentrations in plasma at two hours after Day 3 dosing were in a range between 0.02 and 0.19 micrograms/ml for fine granules and were in a range between 0.11 and 0.42 micrograms/ml for capsules. 3. Urine samples were collected from four patients receiving fine granules and four patients receiving capsules. Drug levels were determined to be 3 micrograms/ml at post-treatment 48 hours for fine granules and post-treatment 72 hours for capsules. Urinary excretion rates of AZM in three patients on capsules lied in a range between 4.69 and 10.17%. 4. Effectiveness of AZM in fine granules was evaluated in 128 patients having a total of 19 different infections. AZM was rated "excellent" in 51 patients, "good" in 63, "fair" in 8, "poor" in 6, resulting in an efficacy rate of 89.1%. Effectiveness of AZM in capsular form was evaluated in 23 patients with five different infections. AZM was found "excellent" in 13 patients and "good" in 10, resulting in an efficacy rate of 100%. 5. AZM in fine granules eradicated 45 strains of 54 in 8 different bacteria. AZM in capsules eradicated 9 strains of 10 strains in 6 different bacteria. 6. As for adverse reactions, one patient complained of eruption, one vomiting, one loose stool, five diarrhea, when administered with fine granular form of AZM. One patient on AZM capsules experienced urticaria and vomiting. 7. As for abnormal laboratory changes, three patients were found with decreased WBC, seven with increased eosinophil, two with increased GOT and GPT, one with increased GPT. They were all on fine granular form of AZM. As far as abnormalities found in patients administered with AZM in capsular form, two showed decreased WBC, one decreased WBC along with increased eosinophil, and three increased eosinophil.

A diagnosis of hepatocellular toxicosis attributable to carprofen administration was made in 21 dogs on the basis of development of clinical signs and clinicopathologic abnormalities associated with hepatic disease and histopathologic documentation of hepatic necrosis. Clinical signs of toxicosis were anorexia, vomiting, and icterus. Hyperbilirubinemia and high serum activities of alanine transaminase, alkaline phosphatase, and aspartate transaminase were the most notable clinicopathologic abnormalities. In 7 of 9 dogs in which urinalyses were performed, abnormalities suggestive of renal tubular disease were detected. Clinical course of toxicosis was variable; however, most dogs had resolution of clinical signs and improvement or resolution of biochemical abnormalities with discontinuation of the drug and administration of supportive care. As with any medication, clients should be informed of possible adverse effects and reactions associated with administration of carprofen. In the event of those signs, clients should be instructed to immediately discontinue administration of carprofen to their dog and contact their veterinarian.

The safety of tacrine (Cognex), a centrally active, reversible acetylcholinesterase inhibitor approved in 1993 for the treatment of mild to moderate dementia of the Alzheimer type, was evaluated in 2,706 patients with Alzheimer disease (AD) in clinical trials and in 9861 patients with AD in a treatment investigational new drug (TIND) program. More than 190,000 patients in the United States received tacrine during the first 2 years following marketing approval. The most common tacrine-associated adverse events were elevated liver transaminase levels [alanine aminotransferase (ALT) and, to a lesser degree, aspartate aminotransferase] and peripheral cholinergic events involving primarily the digestive system (nausea, vomiting, diarrhea, dyspepsia, anorexia, and weight loss). Based on clinical trial experience, potentially clinically significant (>3 x upper limit of normal) ALT elevations occurred in 25% of patients, requiring routine monitoring early in treatment. The elevations were almost always asymptomatic, rarely accompanied by significant increases in bilirubin, and related to time on drug rather than to dose (90% occurred within the first 12 weeks of treatment). Gastrointestinal events were related to dose and generally of mild to moderate intensity. Tacrine-associated events, including ALT elevations, were reversible. Cholinergic events were manageable with dosage adjustment. Tacrine was not associated with permanent liver injury in clinical trials or a TIND setting.

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 9-year-old spayed female Poodle was admitted because of vomiting of 3 weeks' duration, lethargy, and anorexia. Palpation of the cranial portion of the abdomen elicited signs of pain. Principal laboratory abnormalities included mild segmented neutrophilia, lymphopenia, high serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities, and hyperbilirubinemia. Radiography revealed foamy appearing areas of mineral opacity in the region of the gallbladder. Ultrasonographically, a hyperechoic structure with acoustic shadowing was seen in the same region, and extrahepatic bile ducts were distended. Cholecystectomy was performed. The gallbladder wall felt thicker than normal and was bluish-white. Multiple choleliths were found in the gallbladder and extrahepatic bile ducts. Histologic examination revealed chronic proliferative lymphoplasmacytic cholecystitis with mineralization and a well-differentiated adenocarcinoma of the gallbladder neck. A diagnosis of porcelain gallbladder was made. The dog recovered without complications and was healthy 14 months after surgery. To our knowledge, porcelain gallbladder has not been reported in dogs. In human patients, it is defined as intramural mineralization of the gallbladder commonly associated with gallbladder neoplasia. Early recognition is important for appropriate surgical treatment.

AG331 (N6-[4-(morpholinosulfonyl)benzyl]-N6-methyl-2, 6-diaminobenz-[c,d]-indole glucuronate) is a lipophilic thymidylate synthase inhibitor with activity in solid tumor models. On the basis of preclinical data supporting regimens of frequent drug administration, we performed a Phase I trial of AG331 as a 5-day continuous infusion repeated every 3 weeks. Twenty-nine patients were entered at doses ranging from 25 to 1000 mg/m2/day. The major side effects were mild to moderate fatigue, nausea, vomiting, diarrhea, and fever. At doses >/=400 mg/m2, acute reversible elevation of bilirubin, aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltranspeptidase was observed. All patients who received >/=600 mg/m2/day experienced elevated alanine aminotransferase. Elevated liver function tests were evident by day 3 of the infusion and had resolved by day 8 in the majority. This toxicity was dose limiting at 1000 mg/m2/day, at which dose two of two patients developed grade 4 reversible hyperbilirubinemia in addition to the enzyme elevations. Serum and urine samples were analyzed by a novel high-pressure liquid chromatography method for the determination of the pharmacokinetics of AG331. Over the 50-1000 mg/m2/day dose range, mean total clearance ranged from 11.6 to 30.0 liters/h/m2, and volume of distribution at steady state ranged from 279.5 to 758.7 liters/m2. These parameters were dose independent over the dose range tested. The harmonic mean terminal half-life of AG331 was 20.2 h. Less than 5% of an AG331 dose is eliminated unchanged in the urine. Both the administered dose and exposure to the drug were related to the changes in bilirubin and aminotransferase blood levels. Evidence for inhibition of thymidylate synthase was obtained at doses ranging from 100 to 1000 mg/m2 in seven patients; plasma deoxyuridine concentrations at end-infusion were 1.8-3.8-fold higher than pretreatment values. Because of the nature of toxicity on this schedule, more extensive Phase II evaluation is not recommended, although an AG331 dose of 800 mg/m2/day for 5 days is tolerable. Exploration of less frequent dose administration is under way.
