Opium Poppy: Papaver somniferum Member of the Papaveraceae, poppy family Large flashy yearly with prominent blossoms (white, pink, red, purple) Fruit is a case that produces latex with a few powerful alkaloids Latex is gathered from cut cases (latex overflows out and dries – got latex scratched dry) - dried latex called opium

Slide 4

Slide 5

Opium Poppy Native to the Mediterranean range Oldest confirmation of poppy use was presence of a poppy container found with religious antiquities from a collapse Spain that are dated 7500 years of age Evidence of spread in Europe from 3000 to 5000 years prior Reasons for use at these destinations obscure

Slide 6

Ancient therapeutic use Poppy was respected by a few old social orders for its pain relieving properties and its capacity to instigate rest Opium latex has a long history of utilization for agony mitigate and inciting rest among Babylonia, Egyptian, Greek, and Roman civic establishments Opium eaten, intoxicated, and smoked Most regular technique was to break up opium in liquor – opium wine

Slide 7

Mediterranean social orders Writings of Hippocrates, Theophrastus, Dioscorides, and Galen show proof of the boundless utilization of opium In eastern Mediterranean it appears that poppy likewise got to be esteemed for its opiate use Ancient goddess of Crete is delineated wearing a crown with 3 poppy cases

Slide 9

Opium Alkaloids Many alkaloids have been distinguished in opium latex (sedatives) - possibly upwards of 50 Morphine and codeine most imperative Morphine first alkaloid recognized from any plant in 1806 and the torment assuaging properties soon perceived Morphine (like crude opium) is unequivocally addictive and due to this its general restorative use declined in 20 th century Still medication of decision for instances of serious torment

Slide 10

Morphine influences the focal sensory system additionally actuates languor and can discourage breath - overdose can bring about death through respiratory disappointment Cause has high physical reliance Has moderately low oral movement Became medication of decision to treat war wounds amid Civil War - made numerous addicts

Slide 11

Codeine most broadly utilized sedative Only 1/5 as solid as morphine and still addictive Effective in oral prescription and frequently utilized as a part of mix with non-sedative mixes Codeine is particularly compelling in hack syrups since it stifles the hacking reflex

Slide 12

Heroin In 1898, Bayer Pharmaceuticals presented heroin which they believed was a non-addictive sedative and more successful than morphine and codeine Heroin is a semi-engineered subsidiary of morphine - diacetyl morphine Widely accessible in over the counter tonics and hack syrups from 1898 to 1914 - mail request indexes, and so on

Slide 13

Heroin Within a couple of years more than 1 million individuals dependent on heroin in only us Soon understood that it was very addictive than morphine - really six times more addictive In US utilization of heroin is illicit put under Harrison Act of 1914 Heroin still utilized therapeutically as a part of different nations Heroin habit a noteworthy issue around the world

Slide 14

Isoquinoline alkaloids

Slide 15

Opiates

Slide 16

Mode of activity Opiates tie to sedative receptors in film of neurons of the mind and spinal segment (ID\'d in 1970s) The characteristic ligands that typically tie to these receptors are endorphins and enkephalins (little peptides) These peptides are discharged at neurotransmitters on neurons required in transmitting torment signs to the cerebrum

Slide 17

Opiate receptors When enkephalins tie to the sedative receptors they repress neurons from transmitting torment signal - torment signal does not achieve cerebrum Inhibit arrival of neurotransmitter "Substance P" Substance P utilized by the tactile neurons required in the view of incessant and/or extreme torment

Slide 19

Opiate receptors Peptides and receptors shape an unpredictable neurotransmitter framework that assumes a noteworthy part in controlling torment, happiness, and inspiration Also required in other organic occasions - stress reactions, resistant direction, breath, endocrine reactions Different classes of sedative receptors

Slide 20

Opiate receptors Three (or 4) classes of sedative receptors - with subtypes of each Opioids apply their belongings by initiating one or a greater amount of these receptors Pain help includes enactment of one write receptors in the cerebrum and another in the spinal rope Other receptors are included in respiratory dejection and rapture

Slide 21

Opiate receptors m (mu) receptors - absense of pain, elation k (kappa) receptors - sedation, spinal rope absense of pain d (delta) receptors - Antitussive (hacking) properties, emesis (retching), and anticholinergic (blockage) sigma (?) receptors cardiovascular incitement

Slide 22

Opiates Morphine and alternate sedatives tie these same receptors Morphine particularly ties to m receptors Explains why sedatives are magnificent torment executioners However, they are likewise exceedingly addictive
