Morphine is a pain medication of the opiate family which is found naturally in a number of plants and animals. Potentially serious side effects include decreased respiratory effort and low blood pressure. The primary source of morphine is isolation from poppy straw of the opium poppy.
Morphine is used primarily to treat both acute and chronic severe pain. It is also used for pain due to myocardial infarction and for labor pains. However, concerns exist that morphine may increase mortality in the event of non ST elevation myocardial infarction. Side-effects of nausea and constipation are rarely severe enough to warrant stopping treatment.
Morphine jodom video er beneficial in reducing the symptom of shortness of breath due to both cancer and noncancer causes. Morphine is also available as a slow-release formulation for opiate substitution therapy OST in Austria, Bulgaria, and Slovenia, for addicts who cannot tolerate either methadone or buprenorphine. Relative contraindications to morphine include:. Like loperamide and other opioids, morphine acts on the myenteric plexus in the intestinal tract, reducing gut motility, causing constipation.
By inhibiting gastric emptying and reducing propulsive jodom video er of the intestine, morphine decreases the rate of intestinal transit. Reduction in gut secretion and increased intestinal fluid absorption also contribute to the constipating effect.
Opioids also may act on the gut indirectly through tonic gut spasms after inhibition of nitric oxide generation. Clinical studies consistently conclude that morphine, like other opioids, often causes hypogonadism and hormone imbalances in chronic users of both sexes. This side effect is dose-dependent and occurs in both therapeutic szajkowska karolina goceva recreational users.
Morphine can interfere with menstruation in women by suppressing levels of luteinizing hormone. This effect may cause the increased likelihood of osteoporosis and bone fracture observed in chronic morphine users.
Studies suggest the effect is temporary. As of [update]the effect of low-dose or acute use of morphine on the endocrine system is unclear. Most reviews conclude that opioids produce minimal impairment of human performance on tests of sensory, motor, or attentional abilities. However, recent studies have jodom video er able to show some impairments caused by morphine, which is not surprising, given that morphine is a central nervous system depressant.
Morphine has resulted in impaired functioning on critical flicker frequency a measure of overall CNS arousal and impaired performance on the Maddox wing test a measure of the deviation of the visual axes of the eyes.
Few studies have investigated the effects of morphine on motor abilities; a high dose of morphine paper flower origami pdf impair finger jodom video er and the ability to maintain a low constant level of isometric force i. In terms of cognitive abilities, one study has shown that morphine may have a negative impact on anterograde and retrograde memory but these effects are minimal and transient.
Overall, it seems that acute doses jodom video er opioids in non-tolerant subjects produce minor effects in some sensory and motor abilities, and perhaps also in attention and cognition.
It is likely that the effects of morphine will be more pronounced in opioid-naive subjects than chronic opioid users. In chronic opioid users, such as those on Chronic Opioid Analgesic Therapy COAT for managing severe, chronic painbehavioural testing has shown jodom video er functioning on perception, cognition, coordination and behaviour in most cases. One study  analysed COAT patients to determine whether they were able to safely operate a motor vehicle.
The findings from this study suggest that stable opioid use does not significantly impair abilities inherent in driving this includes physical, cognitive and perceptual skills.
COAT patients showed rapid completion of tasks that require the speed of responding for successful performance e. These jodom video er showed no impairments in higher-order cognitive abilities i.
COAT patients appeared to have difficulty following instructions and showed a propensity toward impulsive behaviour, yet this did not reach statistical significance. It is important to note that this study reveals that COAT patients have no domain-specific deficits, which supports the notion that chronic opioid use has minor effects on psychomotorcognitiveor neuropsychological functioning.
Morphine is a highly addictive substance. In controlled studies comparing the physiological and subjective effects of heroin and morphine in individuals formerly addicted to opiates, subjects showed no preference for one drug over the other. Equipotent, injected doses had comparable action courses, with no difference in subjects' self-rated feelings of euphoria, ambition, nervousness, relaxation, drowsiness, or sleepiness. Morphine and heroin were also much more likely to produce euphoria and other positive subjective effects when compared to these other opioids.
Heroin is jodom video er to jodom video er before binding to the opioid receptors in the brain and spinal cord, where morphine causes the subjective effects, which is what the addicted individuals are seeking. CCK-antagonist drugs, specifically proglumidehave been shown to slow the development of tolerance to morphine. Cessation of dosing with morphine creates the prototypical opioid withdrawal syndrome, which, unlike that of barbituratesjodom video eralcoholor sedative-hypnotics, is not fatal by itself in neurologically healthy patients without heart or lung problems.
Acute morphine withdrawal, along with jodom video er of any other opioid, proceeds through a number of stages. Other opioids differ in the intensity and length of each, and weak opioids and mixed agonist-antagonists may have acute withdrawal jodom video er that do not reach the highest level. As commonly cited [ by whom? In advanced stages of withdrawal, ultrasonographic evidence of pancreatitis has been demonstrated in some patients and is presumably attributed to spasm of the pancreatic sphincter of Oddi.
Early symptoms include watery eyes, insomnia, diarrhea, runny nose, yawning, dysphoriasweating, and in some cases a strong drug craving. Severe headache, restlessness, irritability, loss of appetite, body aches, severe abdominal pain, nausea and vomiting, tremors, and even stronger and more intense drug craving appear as the syndrome progresses.
Severe depression and vomiting are very common. During the acute withdrawal period, systolic and diastolic blood pressures increase, usually beyond premorphine levels, and heart rate increases,  which have potential to cause a jodom video er attack, blood clot, or stroke. Chills or cold flashes with goose bumps " cold turkey " alternating with flushing hot flasheskicking movements of the legs "kicking the habit"  and excessive sweating are also characteristic symptoms.
At any point during this process, jodom video er suitable narcotic can be administered that will dramatically reverse the withdrawal symptoms. Sudden withdrawal by heavily dependent users who are in poor health is very rarely fatal. Morphine withdrawal is considered less dangerous than alcohol, barbiturate, or benzodiazepine withdrawal. The psychological dependence associated with morphine addiction is complex and protracted. Long after the physical need jodom video er morphine has passed, the addict will usually continue to think and talk about the use of morphine or other drugs and feel strange or overwhelmed coping with daily activities without being under the influence of jodom video er.
Psychological jodom video er from morphine is usually a very long and painful jodom video er. Without intervention, the syndrome will run its course, and most of the overt physical symptoms will disappear within 7 to 10 days including psychological dependence.
A high probability of relapse exists after morphine withdrawal when neither the physical environment nor the behavioral motivators that contributed to the abuse have been altered. Testimony to morphine's addictive and reinforcing nature is its relapse rate. A large overdose can cause asphyxia and death by respiratory depression if the person does not receive medical attention immediately.
The latter completely reverses morphine's effects, but may result in immediate onset of withdrawal in opiate-addicted subjects. Multiple doses may be needed. Morphine is the prototypical opioid and is the standard against which other opioids are tested. They are also found on the terminal axons of primary afferents within laminae I and II substantia gelatinosa of the spinal cord and in the spinal nucleus of the trigeminal nerve.
Its intrinsic activity at the MOR is heavily dependent on the assay and tissue being tested; in some situations it is a full agonist while in others it can be a partial agonist or even antagonist.
Its primary actions of therapeutic value are analgesia and sedation. Activation of the MOR is associated with analgesia, sedation, euphoriaphysical dependenceand respiratory depression.
Activation of the KOR is associated with spinal analgesia, miosis pinpoint pupilsand psychotomimetic effects. The DOR is thought to play a role in analgesia. The effects of morphine can be countered with opioid receptor antagonists such as naloxone and naltrexone ; the development of tolerance to morphine may be inhibited by NMDA receptor antagonists such as ketamine or dextromethorphan. It is believed that the strong opioid with the most incomplete cross-tolerance with morphine is either methadone or dextromoramide.
Studies have shown that morphine can alter the expression of a number of genes. A single injection of morphine has been shown to alter the expression of two major groups of genes, for proteins involved in mitochondrial respiration and for cytoskeleton -related proteins.
Morphine has long been known to act on receptors expressed on cells of the central nervous system resulting in pain relief and analgesia. This possibility increased interest in the effect of chronic morphine use on the immune system. The jodom video er step of determining that morphine may affect the immune system was to establish that the opiate receptors known to be expressed on cells of the central nervous system are also expressed on cells of the immune system.
One study successfully showed that dendritic cellspart of the innate immune system, display opiate receptors. Dendritic cells are responsible for producing cytokines mustapha dance, which are the tools for communication in the immune system.
This same study showed that dendritic cells chronically treated with morphine during their differentiation produce more interleukin Jodom video era cytokine responsible for promoting the proliferation, growth, and differentiation of T-cells another cell of the adaptive immune system and less interleukin ILa cytokine responsible for promoting a B-cell immune response B cells produce antibodies to fight off infection.
This regulation of cytokines appear to occur via the p38 MAPKs mitogen-activated protein kinase -dependent pathway. Usually, the p38 within the dendritic cell expresses TLR 4 toll-like receptor 4which is activated through the ligand LPS lipopolysaccharide.
This causes the p38 MAPK to be phosphorylated. When the dendritic cells are chronically exposed to morphine during their differentiation process then treated with LPS, the production of cytokines is different. The exact mechanism through which the production of one cytokine is increased in favor over another is not known.
Most likely, the morphine causes increased phosphorylation of the p38 MAPK. This increased production of IL causes increased T-cell immune response. Further studies on the effects of morphine on the immune system have shown that morphine influences the production of neutrophils and other cytokines. Since cytokines are produced as part of the immediate immunological response inflammationit has been suggested that they may also influence pain. In this way, cytokines may be a logical target for analgesic development.
Recently, one study has used an animal model hind-paw incision to observe the effects of morphine administration on the acute immunological response.
Following hind-paw incision, pain thresholds and cytokine production were measured. Normally, cytokine production in and around the wounded area increases in order to fight infection and control healing and, possibly, to control painbut pre-incisional morphine administration 0.
The authors suggest that morphine administration in the acute post-injury period may reduce resistance to infection and may impair the healing of the wound. Morphine can be taken orallysublinguallybucallyrectallysubcutaneouslyintranasallyintravenouslyintrathecally or epidurally and inhaled via jodom video er nebulizer. As a recreational drug, it is becoming more common to inhale jodom video er Chasing the Dragon "but, for medical shia urdu books pdf, intravenous IV injection is the most common method of administration.
M3G does not undergo opioid receptor binding and has no analgesic effect. Metabolism rate is determined by gender, age, diet, genetic makeup, disease state if anyand use of other medications. Morphine can be stored in fat, and, thus, can be detectable even after death.
Morphine can cross the blood—brain barrierbut, because of poor lipid solubility, protein binding, rapid conjugation with glucuronic acid and ionization, it does not cross easily.
