In popular culture
In the pilot episode of Breaking Bad, Walter White first synthesizes methamphetamine through the Nagai route, using  red phosphorus and iodine to reduce pseudoephedrine. In the episode "Vitamin D" of Glee, Terri takes a job as the school nurse to stop her husband, Will Schuester, from becoming closer to guidance counsellor Emma Pillsbury (Jayma Mays), but is fired after giving the students performance-enhancing pseudoephedrine tablets. In her 2013 single "Avant Gardener", Australian rock musician Courtney Barnett refers to the effects of pseudoephedrine: "Reminds me of the time / When I was really sick and I / Had too much pseudoephedrine and I / Couldnt sleep at night". In her 2017 album Melodrama, pop artist Lorde references pseudoephedrine on the song "Writer in the Dark". The lyric reads: "I still feel you, now and then / Slow like pseudoephedrine / When you see me, will you say Ive changed?" Synthesis
Although pseudoephedrine occurs naturally as an alkaloid in certain plant species (for example, as a constituent of extracts from the Ephedra species, also known as ma huang, in which it occurs together with other isomers of ephedrine), the majority of pseudoephedrine produced for commercial use is derived from yeast fermentation of dextrose in the presence of benzaldehyde. In this process, specialized strains of yeast (typically a variety of Candida utilis or Saccharomyces cerevisiae) are added to large vats containing water, dextrose and the enzyme pyruvate decarboxylase (such as found in beets and other plants).
