Drug absorption in the human body depends on the dissolution rate of the drug. Suitable dissolution characteristics are important to ensure that the drug will achieve the desired therapeutic effects. To assess the similarity of dissolution rates of several drug lots, we apply a general growth curve model with different covariance structures. The Box-Cox power transformation and the naive log tr...

Biotechnology is often presented as if progress in the past two decades represented a major success, but the reality is quite different. For example, ten major classes of antibiotics were discovered between 1935 and 1963, but after 1963 there has been just one, the oxazolidones. To illustrate the possibilities of doing better by taking account of the real behaviour of metabolic systems, we can ...

In this review, we focus on cyclic voltammetry as a reliable electrochemical technique to study mechanisms, kinetics and thermodynamics of various types of drug-drug interactions. While we present and discuss six theoretical models relevant to analyze drug-drug (or drug-DNA) interactions, we also give hints about recent experimental achievements in this field. In addition, we provide the reader...

Some limitations of existing data are first identified and discussed. They include the reliance on self-reports; the indirect relationship between available indicators and the underlying quantities of greatest interest; and an overemphasis on measures of drug use at the expense of other factors, such as externalities associated with drug control efforts. Four encouraging trends are the ongoing ...

The drug release analysis and optimization for drug-eluting stents in the arterial wall are studied, which involves mechanics, fluid dynamics, and mass transfer processes and design optimization. The Finite Element Method (FEM) is used to analyze the process of drug release in the vessels for drug-eluting stents (DES). Kriging surrogate model is used to build an approximate function relationshi...

background: chronic obstructive pulmonary disease (copd) is usually considered one of the leading causes of death worldwide, so finding proper therapeutic strategies for this disease is of high importance. in this meta-analysis, we reviewed the existing literature on the efficacy and safety of conventional long acting beta agonists (labas) in copd patients. methods: we searched medline and goog...
