4 Drug and Medication Information
4.1 Therapeutic Uses

Paracelsus, a physician and proponent of alchemy in sixteen century Europe, and his followers favored the use of metals, including antimony, as drugs. The view of the Paracelsus followers diverged from the teachings of Galen (c. AD 13-201), a preeminent Roman physician who considered metals to be poisonous. The period of c. 1560-1660 was termed the 'antimony war' and reflects the conflict in medicine between Galenic medicine and the practices of Paracelsus. /Former use/

5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

A study of the retention patterns of labeled antimony in mice following inhalation of particles formed at different temp was conducted. The lower temp aerosol was more sol & left the lung rapidly, localizing in the skeleton. The 2 aerosols produced at higher temp resulted in (124)antimony remaining in the lung for extended periods.

Environment and nutrition influence antimony concentrations of human tissues, causing large differences among individuals. Extremely high levels were found in the lung and bone tissues but not in liver or kidney of deceased antimony smelter workers. The lung contain the highest antimony levels of human tissues. The distribution of antimony is not homogeneous within organs or tissues. ... Great variations of antimony content were found in normal human platelets, serum albumin, and different tissues. /Antimony/

Arsenic and antimony are toxic metalloids, naturally present in the environment and all organisms have developed pathways for their detoxification. The most effective metalloid tolerance systems in eukaryotes include downregulation of metalloid uptake, efflux out of the cell, and complexation with phytochelatin or glutathione followed by sequestration into the vacuole. Understanding of arsenic and antimony transport system is of high importance due to the increasing usage of arsenic-based drugs in the treatment of certain types of cancer and diseases caused by protozoan parasites as well as for the development of bio- and phytoremediation strategies for metalloid polluted areas. However, in contrast to prokaryotes, the knowledge about specific transporters of arsenic and antimony and the mechanisms of metalloid transport in eukaryotes has been very limited for a long time. Here, we review the recent advances in understanding of arsenic and antimony transport pathways in eukaryotes, including a dual role of aquaglyceroporins in uptake and efflux of metalloids, elucidation of arsenic transport mechanism by the yeast Acr3 transporter and its role in arsenic hyperaccumulation in ferns, identification of vacuolar transporters of arsenic-phytochelatin complexes in plants and forms of arsenic substrates recognized by mammalian ABC transporters. /Antimony/

5.2 Metabolism/Metabolites

Recently, tellurium (Te), antimony (Sb) and germanium (Ge) have been used as an alloy in phase-change optical magnetic disks, such as digital versatile disk-random access memory (DVD-RAM) and DVD-recordable disk (DVD-RW). Although these metalloids, the so-called "exotic" elements, are known to be non-essential and harmful, little is known about their toxic effects and metabolism. Metalloid compounds, tellurite, antimonite and germanium dioxide, were simultaneously administered to rats. Their distributions metabolites were determined and identified by speciation. Te and Sb accumulated in red blood cells (RBCs): Te accumulated in RBCs in the dimethylated form, while Sb accumulated in the inorganic/non-methylated form. In addition, trimethyltelluronium (TMTe) was the urinary metabolite of Te, whereas Sb in urine was not methylated but oxidized. Ge was also not methylated in rats. These results suggest that each metalloid is metabolized via a unique pathway. /Antimony metabolites/

5.3 Biological Half-Life

Airborne factory dust (with a volume median diameter of 5.0 um and a geometric standard deviation of 2.1 um) from a Swedish copper smeltery contained antimony (1.6 weight %) and arsenic (19 weight %). The dust was neutron activated and intratracheally instilled in hamsters. In vivo measurements of lung clearance were undertaken of the radionuclides (76)arsenic, (122)antimony, and (124)antimony. Two phases were recognized in the clearance curves. The approx half-time for the initial phase was about 40 hr for antimony trioxide, and 30 hr for antimony dust. The second phase had an approx half-time of 20-40 days for antimony trioxide and antimony dust. The low solubility of antimony in factory dust combined with a long biological half-time may be of importance in explaining the observed lung accumulation of antimony in exposed workers.
