The general aim of this thesis was to improve the understanding of the in vivo pharmacokinetics and, in particular, the metabolism of finasteride, a 5α-reductase inhibitor used in the treatment of enlarged prostate glands and male pattern baldness. CYP3A4 has been identified as the major enzyme involved in the sequential metabolism of finasteride to ω-OH finasteride (M1) and ω-COOH finasteride (M3). The consequences of induced and inhibited metabolism on the pharmacokinetics of finasteride and its metabolites were investigated in humans and pigs. Both studies included bile collection. The coll

In this thesis, a multi-scale approach is provided to a pharmacokinetic and a pharmacodynamic problem. The first part of this research provides a realistic mathematical physiological model of the liver to predict drug drug interactions (DDIs). The model describes the geometry of a lobule (liver unit) and integrates the exchange processes, diffusion and active transport, between the hepatocytes and the blood and possible drug-drug interactions such as; reversible inhibition, mechanistic based inhibition (MBI) and enzyme induction. The liver model is subsequently integrated into a PBPK model wit

Indiana University-Purdue University Indianapolis (IUPUI)<br>Polypharmacy is a general clinical practice, there is a high chance that multiple administered drugs will interfere with each other, such phenomenon is called drug-drug interaction (DDI). DDI occurs when drugs administered change each other's pharmacokinetic (PK) or pharmacodynamic (PD) response. DDIs in many ways affect the overall effectiveness of the drug or at some times pose a risk of serious side effects to the patients thus, it becomes very challenging to for the successful drug development and clinical patient care.

碩士<br>臺北醫學大學<br>藥學研究所<br>97<br>Carrier-mediated processes, often referred to as transporters which located on the membrane, play key roles in the reabsorption and secretion of many endogenous and xenobiotic compounds by the kidney. In recent years, the specific roles of such transporters in drug disposition and drug-drug interactions become more important. The purpose of this study is to estimate the interaction of drugs with the organic anion transporter I (OATI) in the kidney. An accuracy, precision, simple and specific HPLC method was developed to detect the concentration of p-aminohipp

Abstract:
There are numerous areas of application for which PKPD models are a valuable tool. We studied dose linearity, bone penetration and drug-drug interactions of antibiotics by PKPD modeling. Knowledge about possible saturation of elimination pathways at therapeutic concentrations is important for studying the probability of successful treatment of dosage regimens via MCS at various doses, other modes of administration, or both. We studied the dose linearity of flucloxacillin and piperacillin. For data analysis of the dose linearity studies, population PK modeling and MCS was used. Population PK ha

Trabalho Final de Mestrado Integrado, Ciências Farmacêuticas, Universidade de Lisboa, Faculdade de Farmácia, 2016<br>A polimedicação é um problema atual que coloca os doentes sobre um elevado risco de sofrerem interações medicamentosas. Isto verifica-se sobretudo na população idosa, que devido às comorbilidades e às mudanças fisiológicas associadas à idade, são especialmente vulneráveis a estas interações. Os mecanismos envolvidos nas interações entre fármacos podem afetar a farmacocinética ou a farmacodinâmica de um ou de ambos os fármacos em questão. O grande desafio da prática clínica é

Abstract:
碩士<br>國立臺灣大學<br>藥學研究所<br>93<br>In recent years, St. John''s wort (Hypericum perforatum, SJW) was used as an alternative therapy for the treatment of mild to moderate depression. Several active compounds from SJW have been isolated, including hypericin, pseudohypericin and hyperforin, etc. Besides, SJW may affect the activities of P-glycoprotein (Pgp) and cytochrome P450 (CYPs) in rats and human. In some clinical observations, SJW can reduce the plasma concentrations of indinavir, a HIV protease inhibitor, which is a substrate of CYP3A4 and Pgp. Therefore, a rat small intestine perfusion model
