Examples of toxic agents are toxic metals, toxic chemicals, microbe neurotoxins, radiation particles and even specific neurotransmitters when the system is out of balance. Also some types of drugs, e.g alcohol , [ 1 ] and some venom , e.g. from the puff adder ( Bitis arietans ) or brown recluse spider ( Loxosceles reclusa ) are toxic to cells.
The Chinese definition of "bioequivalence" entails having the test drug's geometric mean C max, AUC (0–t), and AUC (0–∞) fall into 80%–125% of the reference drug in both fasting and fed states. The reference drug should be preferably the original brand-name drug, then (if not available) an internationally-recognized generic approved by ...
The type of linker, cleavable or noncleavable, lends specific properties to the cytotoxic drug. For example, a non-cleavable linker keeps the drug within the cell. As a result, the entire antibody, linker and cytotoxic (anti-cancer) agent enter the targeted cancer cell where the antibody is degraded into an amino acid.
Chemotherapy of cancer, treatment of skin diseases and treatment of infections are common use cases of cytostatic drugs; although they can also affect normal and healthy cells and tissues. [3] [4] Active hygienic products generally contain cytostatic substances. Cytostatic mechanisms and drugs generally occur together with cytotoxic ones.
Before administration, a lyophilized drug is reconstituted as a liquid before being administered. This is done by combining a liquid diluent with the freeze-dried powder, mixing, then injecting. Reconstitution usually requires a reconstitution and delivery system to ensure that the drug is correctly mixed and administered.
Examples include melphalan and chlorambucil. [6] The following three groups are almost always considered "classical". Nitrogen mustards [7] Cyclophosphamide — the most widely used alkylating agent of modern times; Chlormethine also known as mechlorethamine or mustine (HN2) — the first alkylating agent to receive regulatory approval
The drug is a semi-synthetic analogue of another cancer-fighting drug, vinblastine. Vinorelbine is included in the class of pharmaceuticals known as vinca alkaloids, and many of its characteristics mimic the chemistry and biological mechanisms of the cytotoxic drugs vincristine and vinblastine.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
