AbstractThe aim of this study is to compare the clinical and biochemical outcomes of triptorelin acetate (TPA) versus triptorelin pamoate (TPP) treatment in girls with central precocious puberty. A total of 60 patients with idiopathic CPP were retrospectively recruited. Thirty girls were treated with triptorelin acetate 3.75?mg/month (TPA group) and thirty girls in a second group received triptorelin pamoate 3.75?mg/4?weeks (TPP group). Patient follow-up at 12 and 24?months included GnRH Test at 12?months and baseline LH at 24?months. Patients were monitored with pelvic ultrasound, X-Ray of the hand and wrist and anthropometric evaluations. A total of 60/60 girls showed a good response to both formulations. Significant reductions in basal and LH peaks, estradiol values, breast pubertal stage, progression of bone age and growth velocity rate after 12?months treatment were obtained in both groups, demonstrating the equivalence of the two formulations in regulating the hypothalamic–pituitary-gonadal (HPG) axis. Triptorelin pamoate provided a more effective and significant reduction in LH peak after 12?months in comparison with triptorelin acetate more effective in reducing ovarian volume and endometrial thickness. Both formulations were equivalent, even though the LH peak was significantly lower in girls treated with triptorelin pamoate 相似文献

BackgroundTigecycline is an antibiotic that well tolerated for treating complicated infections. It has received attention as an anti-cancer agent and expected to solve two major obstacles, sides effects that accompany chemotherapy and drug resistance, in the breast cancer treatment. However, previous studies reported that the levels in the blood are typically low of tigecycline, so higher doses are needed to treat cancer, that may increase the risk of side effects. To achieve better anti-cancer effects for tigecycline, we need to find a novel adjunct agent.MethodsIn this study, we used different concentration of pyrvinium pamoate combined with tigecycline to treat cell. And assess the effect of two drugs in inhibit cell proliferation, induce cell autophagy, or increase cell apoptosis to evaluate the consequent of combined therapy.ResultsWe observed that after the combined therapy, the cell cycle arrest at G1/s phase, the level of p21 increased, but decreased the levels of CDK2. Others, two drugs via different mechanisms to inhibit cancer cell proliferation and with selective cytotoxic to different cell lines. That could enhance the effect of breast cancer treatment.ConclusionCombining low dose of tigecycline use with pyrvinium pamoate is a novel approach for breast cancer treatment. Appropriate combined therapy in breast cancer is recommended to improve outcomes. Other problems like drug resistance occur in patients or the microbes surrounding breast tissues would confer susceptibility to cancers then influence the effectiveness of treatment, which could be improved through combined therapy. 相似文献

Drugs that are largely restricted to the gastro-intestinal tract (GIT) for their therapeutic efficacy and that are not substantially absorbed into the body are usually inadequately studied in terms of systemic bioavailability. The possibility of systemic effects requires that bioavailabilities be studied to ensure against enhanced toxicity resulting from formulation differences. Pyrantel pamoate falls into this category. High-performance liquid chromatography was employed in this study to determine plasma levels of pyrantel in nine healthy human subjects after administration of tablet and suspension dosage forms. Mean peak plasma concentrations of 37.56 ± 9.37, 35.89 ± 8.94, and 36.22 ± 10.10 ng mL?1 were obtained following administration of 750 mg pyrantel pamoate in three different formulations. The mean tmax values were 2.02 ± 0.12, 2.05 ± 0.356, and 2.05 ± 0.339 h respectively for the above dosage forms; the respective AUC0–9 values were 81.01 ± 12.97, 94.59 ± 17.18, and 101.47 ± 19.59 h ng mL?1. There was no statistically significant difference between the bioavailabilities of the dosage forms tested. Large inter-subject variations were observed. One subject experienced abdominal discomfort and one experienced dizziness. It was not possible to clearly correlate individual variations in absorption with the observed adverse effect because the number of incidents was low (two out of 27 treatments). 相似文献

Objective
To characterize patients treated with olanzapine pamoate in French centers and investigate the conditions of use of olanzapine pamoate in real-life treatment situation.Methods
Data came from French sites participating in an international post-authorization safety study. In this observational study, patients diagnosed with schizophrenia were receiving commercially available olanzapine pamoate, in accordance with their physician's usual standard of care. Data were collected during routine visits within the standard course of patient care.Results
One hundred and thirty eight patients (male, 73.9%; mean age, 39.4 years; mean duration of disease, 12.7 years) received olanzapine pamoate and were included in the study by 32 investigative psychiatrists distributed across 20 different sites (psychiatric hospitals). During the period of analysis, a total of 2975 injections of olanzapine pamoate was administered to the patients. The mean duration of olanzapine pamoate exposure was 475 days (1.3 years). During follow-up, 13.8% of all patients had at least one psychiatric hospitalization, 15.9% had at least one same-day psychiatric hospitalization (information documented for 116 patients), and 44.2% received at least one concomitant drug. Three cases of post-injection delirium/sedation syndrome were reported during the analysis period. Treatment emergent adverse events (incidence, 20.3%) were in line with the known profile of olanzapine.Conclusion
Patients were administered olanzapine pamoate and monitored in compliance with label recommendations. The safety profile assessment of olanzapine pamoate in actual conditions was consistent with that described in clinical studies. 相似文献37.
