1. Quais riscos ao paciente da associação de Clopidogrel 75 mg com Atorvastatina? Em qual concentração de Atorvastatina pode ocorrer interação medicamentosa?
As estatinas metabolizadas pela isoenzima CYP3A4 do citocromo P450 (sinvastatina, atorvastatina e lovastatina) parecem interferir na ação antiplaquetária do clopidogrel, mas não está clara sua significância clínica. É possível que o clopidogrel afete o metabolismo de algumas estatinas 1.
Alguns estudos revelaram que as estatinas metabolizad

2. Phenolic and flavonoid content and in vitro inhibitory effect of some Amazonian fruit juices on CYP3A4 activity
RESUMO Muitos alimentos interagem com medicamentos e podem causar alterações nos efeitos farmacológicos do agente terapêutico coadministrado. A enzima CYP3A4, que pertence ao complexo enzimático do citocromo P450, é responsável pelo metabolismo da maioria dos medicamentos atualmente no mercado e está envolvida em muitas interações medicamentosas. A

3. CYP450 Metabolism of a Semisynthetic Naphthoquinone, an Anticancer Drug Candidate, by Human Liver Microsomes
CNFD (6b,7-dihydro-5H-cyclopenta[b]naphtho[2,1-d]furan-5,6(9aH)-dione) is a semisynthetic naphthoquinone derived from lawsone that has cytotoxic action in different tumor lines and anticancer activity in vivo. Therefore, this molecule is a relevant candidate for drug development, but there is still no information on its human metabolism and systemic eliminat

4. Pharmacogenetic and Pharmacokinetic Assays from Saliva Samples Can Guarantee Personalized Drug Prescription
Resumo Saliva é amplamente utilizada para análises clínicas e laboratoriais. Este estudo propôs o uso de DNA extraído da saliva para genotipagem e farmacocinética do piroxicam. Um método de genotipagem rápido e eficiente foi usado para determinar as variantes alélicas clinicamente relevantes de CYP2C9 (* 2 e * 3), uma vez que fatores genéticos pode

5. Serotonin syndrome associated with methadone and milk thistle seeds: a case report
Abstract Background Serotonin syndrome is rarely, potentially life threatening condition, associated with use of serotonin acting medications and psychoactive drugs. In the majority of cases the symptoms occur soon after the initiation of a new drug or a change in the dose. Objective To present a case report and to describe the possible mechanism of deve

6. Effect of recombinant bovine somatotropin (rbST) treatment on follicular population and development in non-lactating dairy cows
Abstract The aim of this study was to evaluate the long-term effects of recombinant bovine somatotropin (rbST) on follicle population and ovulatory follicle development in non-lactating dairy cows. Twenty-one Jersey cows were allocated in rbST (n=11) or control (n=10) groups. On day -60, cows in rbST group received 500 mg of somatotropin (s.c. Lactotropin®,

7. The use of aromatase inhibitors in boys with short stature: what to know before prescribing?
ABSTRACT Aromatase is a cytochrome P450 enzyme (CYP19A1 isoform) able to catalyze the conversion of androgens to estrogens. The aromatase gene mutations highlighted the action of estrogen as one of the main regulators of bone maturation and closure of bone plate. The use of aromatase inhibitors (AI) in boys with short stature has showed its capability to imp

8. Biotransformation of bromhexine by Cunninghamella elegans, C. echinulata and C. blakesleeana
Abstract Fungi is a well-known model used to study drug metabolism and its production in in vitro condition. We aim to screen the most efficient strain of Cunninghamella sp. among C. elegans, C. echinulata and C. blakesleeana for bromhexine metabolites production. We characterized the metabolites produced using various analytical tools and compared them with

11. ADME studies and preliminary safety pharmacology of LDT5, a lead compound for the treatment of benign prostatic hyperplasia
This study aimed to estimate the absorption, distribution, metabolism and excretion (ADME) properties and safety of LDT5, a lead compound for oral treatment of benign prostatic hyperplasia that has previously been characterized as a multi-target antagonist of α1A-, α1D-adrenoceptors and 5-HT1A receptors. The preclinical characterization of this compound co

12. CYP3A5 genotyping for assessing the efficacy of treatment with simvastatin and atorvastatin
In this work, we examined the impact of polymorphism in the cytochrome P450 (CYP) 3A5 gene, CYP3A5*1 (6986A > G, rs 776746), on the reduction in the lipid levels caused by simvastatin and atorvastatin. We studied 350 hyperlipidemic patients who received 10-40 mg of atorvastatin (n = 175) or simvastatin (n = 175) daily. Genotyping for CYP3A5 was done by PCR-R
