POM morphine, heroin, codeine, papaveretum, noscapine, Bentley compounds

Opiate receptor and calcium channel blockade. Contains morphine and codeine, powerful analgesics.

Papaver somniferum morphine. Morphine is made from opium, the milky sap from the seed capsule of the poppy, Papaver somniferum. It has been used for pain relief for more than 5000 years. In patients who have heart attacks, it not only relieves the pain but also helps breathlessness caused by pulmonary oedema, fluid in the lungs. It makes it easier for the failing heart to pump blood thorough the lungs by relaxing the pulmonary blood vessels. Opium also contains small amounts of papaverine from which a synthetic analogue, verapamil was derived in the 1960s and which is used to control very rapid heart rates.

Nomenclature

Somniferum = from the Latin - bringing sleep.

Other use

Papaver somniferum L. Papaveraceae Opium Poppy Distribution: Asia minor, but has been dated to 5000BC in Spanish caves. Now grows almost everywhere. The oldest medicine in continuous use, described in the Ebers' papyrus (1550 BC), called Meconium, Laudanum, Paregoric and syrup of poppies. Culpeper (1650) on Meconium '...the juyce of English Poppies boyled till it be thick' and 'I am of the opinion that Opium is nothing else but the juyce of poppies growing in hotter countries, for such Opium as Authors talk of comes from Utopia [he means an imaginary land, I suspect]’. He cautions 'Syrups of Poppies provoke sleep, but in that I desire they may be used with a great deal of caution and wariness...' and warns in particular about giving syrup of poppies to children to get them to sleep. The alkaloids in the sap include: Morphine 12% - affects μ-opioid receptors in the brain and causes happiness, sleepiness, pain relief, suppresses cough and causes constipation. Codeine 3% – mild opiate actions – converted to morphine in the body. Papaverine, relaxes smooth muscle spasm in arteries of heart and brain, and also for intestinal spasm, migraine and erectile dysfunction. Not analgesic. Thebaine mildly analgesic, stimulatory, is made into oxycodone and oxymorphone which are analgesics. Protopine – analgesic, antihistamine so relieves pain of inflammation. Noscapine – anti-tussive (anti-cough). In 2006 the world production of opium was 6,610 metric tons, in 1906 it was over 30,000 tons when 25% of Chinese males were regular users. The Opium wars of the end of the 19th century were caused by Britain selling huge quantities of Opium to China to restore the balance of payments deficit. Laudanum: 10mg of morphine (as opium) per ml. Paregoric: camphorated opium tincture. 0.4mg morphine per ml. Gee’s Linctus: up to 60 mg in a bottle. J Collis Browne’s chlorodyne: cannabis, morphine, alcohol etc. Kaolin and Morph. - up to 60 mg in a bottle. Dover’s Powders – contained Ipecacuana and morphine. Heroin is made from morphine, but converted back into morphine in the body. One gram of poppy seeds contains 0.250mgm of morphine, and while one poppy seed bagel will make a urine test positive for morphine for a week, one would need 30-40 bagels to have any discernible effect.
