Buy Pseudoephedrine Powder Online Pseudoephedrine is a diastereomer of ephedrine and is readily reduce into methamphetamine or oxidize into methcathinone.
Although pseudoephedrine occurs naturally as an alkaloid in certain plant species (for example, as a constituent of extracts. Also know as ma huang, in which it occurs together with other isomers of ephedrine), the majority of pseudoephedrine produce for commercial use is derive from yeast fermentation of dextrose in the presence of benzaldehyde. In this process, specialize strains of yeast (typically a variety of Candida utilis or Saccharomyces cerevisiae) are add to large vats containing water, dextrose and the enzyme pyruvate decarboxylase (such as find in beets and other plants). After the yeast has begin fermenting the dextrose, the benzaldehyde is add to the vats, and in this environment the yeast converts the ingredients to the precursor l-phenylacetylcarbinol (L-PAC). L-PAC is then chemically converted to pseudoephedrine via reductive amination. Buy Pseudophedrine Online
More about Pseudoephedrine
The bulk of pseudoephedrine is produce by commercial pharmaceutical manufacturers in India and China. This is where economic and industrial conditions favor its mass production for export.
It is a sympathomimetic amine. Its principal mechanism of action relies on its direct action on the adrenergic receptor system. The vasoconstriction that It produces is believe to be principally an α-adrenergic receptor response.
It acts on α- and β2-adrenergic receptors, to cause vasoconstriction and relaxation of smooth muscle in the bronchi, respectively.α-adrenergic receptors are locate on the muscles lining the walls of blood vessels. When these receptors are activate the muscles contract, causing the blood vessels to constrict (vasoconstriction). The constrict blood vessels now allow less fluid to leave the blood vessels and enter the nose throat and sinus. Which results in decrease inflammation of nasal membranes, as well as decrease mucus production. Thus, by constriction of blood vessels, mainly those locate in the nasal passages, pseudoephedrine causes a decrease in the symptoms. Activation of β2-adrenergic receptors produces relaxation of smooth muscle of the bronchi,causing bronchial dilation.
