The Pharmacokinetics and Pharmacodynamics of Iron Preparations

Standard approaches are not appropriate when assessing pharmacokinetics of iron supplements due to the ubiquity of endogenous iron, its compartmentalized sites of action, and the complexity of the iron metabolism. The primary site of action of iron is the erythrocyte, and, in contrast to conventional drugs, no drug-receptor interaction takes place. Notably, the process of erythropoiesis, i.e., ...

An Integrated Concept of Carcinogenic- Anticarcinogenic Action

Toxicology and carcinogenic action of pyrrolizidine alkaloids.

The studies of the hepatoxic and hepatocarcinogenic pyrrolizidine alkaloids (PA) have shown that (a) The conventional testing for toxicity and its evaluation on the basis of death occurring a few days after dosing is meaningless for carcino genic agents, (b) A single dose of a water-soluble substance, the main part of which is metabolized and excreted in a few hours after ingestion and which do...
