Cough syrups

Many industrial proce.sses experience. seasonal ri.ses and falls. This means that flow varies. For example, we consume more cough syrup and aspirin in the flu season and less of rhe.se products in other sea.sons. 

In the food production and OTC (Over the Counter) Drug industries, like milk, soups, cough syrup, and juices, outside balanced seals are quite popular. Their design permits easy cleaning of the equipment without pump disassembly. These seals are prominent in the chemical processing industry because all metal components in the seal are located outside the fluid. This avoids problems of galvanic eorro.sion. 

Plastics are extensively used in medicine to package drugs, ointments, and accessories. Plastics serve to protect medicines, surgical/ clinical equipment, medical materials, etc. from contamination and breakage in many ways, from single-service squeeze packs of cough syrup to carrying cases used to ship human eyes between hospital eye banks. 

Gelatin was patented in the United States in 1845 by Peter Cooper, founder of New York s Cooper Union, according to the Jell-O history pages at www.kraftfoods.com. A cough syrup manufacturer bought the patent and introduced Jell-O late in the nineteenth century.

So far, we have discussed only pure substances. However, most materials are neither pure elements nor pure compounds, and so they are not substances in the technical sense of the term (Section A) they are mixtures of these simpler substances, with one substance mingled with another. For example, air, hlood, and seawater are mixtures. A medicine, such as a cough syrup, is often a mixture of various ingredients that has been formulated to achieve an overall biological effect. Much the same can be said of a perfume. 

Achiral-chiral chromatography has also been accomplished using subcritical fluid chromatography (Phinney et al., 1998). In this work, the structurally related [3-blockers, 1,4-benzodiazepines, and two cold medicines were separated using methanol or ethanol modified carbon dioxide mobile phases. The (3-blockers were separated using cyanopropyl and Chiracel OD columns connected in series. Likewise, an amino bonded phase and Chiracel OD column were used for the separation of the 1,4-benzodiazepines. Guaifenesin and phenylpropanolamine from cough syrup were separated on cyanopropyl and Chiralpak AD columns in series.

Schedule V—The drug or other substance has (1) a low potential for abuse relative to the drugs or other substances in Schedule IV, (2) a currently accepted medical use in treatment in the United States, and (3) abuse of the drug or other substance may lead to limited physical dependence or psychological dependence relative to the drugs or other substances in Schedule IV. Example codeine cough syrup. 

Ecstasy-related visits to hospital emergency rooms have skyrocketed in recent years, with approximately 250 reports of Ecstasy-related emergencies in 1994 to more than 4,500 in 2000. The majority of the visits are Ecstasy-induced malignant hyperthermia, the risk of which is increased when Ecstasy is combined with other drugs such as LSD ( candy flipping ), psychedelic mushrooms ( hippie flipping ), methamphetamine ( up Ecstasy ), heroin ( down Ecstasy ), and cocaine, Rohypnol, cough syrup, and antidepressants. 

Chloroform (CHCl ) Toxic and carcinogenic if ingested or inhaled over a long period of time. Formerly used as an anesthetic during surgical procedures, it is currently banned for use in cosmetics and items such as toothpaste and cough syrup. 

There are millions of different precursors for thousands of different dmgs, making it impossible for me to list all of them. I will stick with the more commonly called for items. If you need to find something that I have not listed, look in the Merck Index or Chemical Abstracts to find a reference of where the synthesis of this precursor can be found. At the end of the formulas given here, I have listed some hints or ways to get good precursors out of over the counter medication, like cough syrup, asthma pills, motion sickness pills, etc. Some of these precursors are psychoactive as is, such as ephidrine.
