INTRODUCTION Meloxicam is a nonsteroidal anti-inflammatory agent used widely in therapeutics. It is mainly metabolised by the cytochrome P450 enzyme (CYP) 2C9, with minor involvement of CYP3A4. So far, no information on the oral pharmacokinetics of this drug in adult Mexicans is available. The purpose of this study was to evaluate the oral pharmacokinetics(More)
BACKGROUND The efficacy of contraceptives is affected by its route and ease of administration. Herein, both pharmacokinetics and pharmacodynamics of the once-a-month combined injectable contraceptive medroxyprogesterone acetate (MPA) plus estradiol cypionate (E(2)-Cyp) were compared after intramuscular (IM) or subcutaneous (SC) injection in women of(More)
Significant evidence implicates the endogenous opioid system (EOS) (opioid peptides and receptors) in the mechanisms underlying the psychopharmacological effects of ethanol. Ethanol modulates opioidergic signaling and function at different levels, including biosynthesis, release, and degradation of opioid peptides, as well as binding of endogenous ligands(More)
Clindamycin is an antimicrobial agent metabolized by CYP3A4. Gender may influence the pharmacokinetics of drugs metabolized by this pathway, however, no information about differences in the pharmacokinetics of clindamycin in men and women is available. The purpose of this study was to evaluate gender differences in clindamycin oral pharmacokinetics.(More)
In Experiment 1 groups of rats received single injections of 1, 3, 10, 20 or 40 mg/kg quipazine, and their total 24-hr food and water intake after a 24-hr deprivation period was recorded; there was a dose-related reduction of both food and water intake. In Experiment 2 a group of 15 rats received 5 mg/kg/day, SC quipazine during 29 days, and a control group(More)
e20672 Background: Myelophthisis is a form of bone marrow failure due to replacement of hematopoietic tissue by abnormal tissue, most commonly metastatic carcinomas. This results in extramedullary hematopoiesis, typically in the spleen leading to premature release of hematopoietic cells into the circulation. Peripheral blood findings of myelophthisis may(More)
e16150 Background: Renal cell carcinoma has increased its incidence by 126% since 1950. A local study developed a complete economic evaluation of sunitinib versus IFN in first-line treatment of mRCC in Colombia, finding that sunitinib was more cost-useful and cost-effective. METHODS A Markov model was developed using 6-week cycles for evaluating the(More)
The present experiment explored the anorectic and adipsic effects of fluprazine hydrochloride, a phenylpiperazine compound. Thirty-eight albino rats were randomly assigned either to a control saline group (six rats) or to groups (eight subjects each) receiving an IP dose of fluprazine in saline (1.25, 2.5, 5 or 10 mg/kg). No anorectic effect of the drug(More)
