The rats model has never thoroughly investigated the influence of tramadol on plasma pethidine concentration besides pharmacokinetics. Individually, analgesic ED50s for and are estimated as 3.55 24.21 mg/kg, i.p. Subsequently, their measures decreased to 1.65 11.27 i.p., when both were given in combination at 1:1 from ED50s. Tramadol have a form synergistic interaction, which is therefore class...

Metformin pharmacokinetics in a liquid extemporaneous formulation from commercial tablets was determined paediatric patients. A randomized, transversal clinical trial conducted 34 children and adolescents between 7 17 years of age. were randomized to take metformin the and, after 1-week wash period, 500 mg tablet administered them. Blood samples obtained Whatman 903® cards at 0, 1, 2, 4, 8, 12 ...

PROLOGUE Nonlinear pharmacokinetics, as opposed to the more commonly observed linear pharmacokinetics, is a topic of discussion in most basic pharmacokinetics courses offered to pharmacy students. Although nonlinearity in pharmacokinetics may occur in all aspects of pharmacokinetics (absorption, distribution, and/or elimination), most introductory courses focus on nonlinearity in the metabolism...

Although the fundamental concepts of pharmacokinetics remain the same, ocular pharmacokinetics has its own challenges due to the uniqueness of barrier properties posed by various ocular tissues and its growing complexity with different routes of ocular administration. A thorough understanding of the barrier nature will aid in tailoring a drug or its carrier's physicochemical properties to its a...

The steady-state pharmacokinetics of efavirenz and nevirapine, when used in combination to treat human immunodeficiency virus type 1 (HIV-1)-infected subjects, were investigated. HIV-1-infected persons who had used efavirenz (600 mg once daily) for > or =2 weeks were eligible for study inclusion. The plasma pharmacokinetics of efavirenz were determined over 24 h. Subsequently, nevirapine (400 m...

The selection of an antimicrobial regimen is based on a number of factors, including the nature of the infection, the identity and susceptibility of the pathogens, host characteristics, and the pharmacokinetics and pharmacodynamics of antimicrobial agents. This article provides a comprehensive overview of these factors, with particular attention to pharmacokinetics and monitoring for efficacy a...
