These modifications give ketolides much broader spectrum than other macrolides. Moreover, ketolides are effective against macrolide-resistant bacteria, due to their ability to bind at two sites at the bacterial ribosome as well as having a structural modification that makes them poor substrates for efflux-pump mediated resistance.

Agents that "bind" to the toxin can reduce free or active toxin present. It is possible for this binding to be nonspecific or specific. Activated charcoal is the non-specific binding agent most frequently utilised as it has strong adsorption capacity and could prevent the toxin's enterohepatic recirculation.
Antiprotozoal agents (ATC code: ATC P01) is a class of pharmaceuticals used in treatment of protozoan infection.. A paraphyletic group, protozoans have little in common with each other.
Their new text was first published in 1941 under the title The Pharmacological Basis of Therapeutics: A Textbook of Pharmacology, Toxicology and Therapeutics for Physicians and Medical Student. [1] Because the volume was twice as long as a typical textbook, Macmillan printed few copies, but demand for a readable, up-to-date pharmacological text ...
Pharmacological Reviews is a quarterly peer-reviewed scientific journal publishing review articles on all aspects of pharmacology and related topics. It is published by the American Society for Pharmacology and Experimental Therapeutics. The editor-in-chief is Lynette C. Daws (The University of Texas Health Science Center at San Antonio).
Molecular pharmacology – the discipline of studying drug actions at the molecular level; it is a branch of pharmacology in general. Pharmacogenomics – the study of the human genome in order to understand the ways in which genetic factors determine the actions of medicines. [6] [7]
Some of the substances require conversion into active substances in vivo (e.g., cyclophosphamide).. Cyclophosphamide is one of the most potent immunosuppressive substances. In small dosages, it is very efficient in the therapy of systemic lupus erythematosus, autoimmune hemolytic anemia, granulomatosis with polyangiitis, and other autoimmune diseases.
Illustration showing the hepatic portal vein system. The first pass effect (also known as first-pass metabolism or presystemic metabolism) is a phenomenon of drug metabolism at a specific location in the body which leads to a reduction in the concentration of the active drug before it reaches the site of action or systemic circulation.
