In US, Meperidine Is Approved By Food and Drug Administration for Treatment of Moderate-To-Severe Pain

 

Meperidine

Meperidine belongs to the class of opioid analgesics, which work by relieving the body from the actions of certain chemicals called opioids. Meperidine, also known as Demerol, is recommended for the quick relief of moderate to severe pain, which is delivered either as an intravenous, intramuscular, or oral injection. In the U.S., the drug has also been approved by the FDA (Food and Drug Administration) for the treatment of moderate-to-severe pain.

Besides its antinociceptive, anti-inflammatory, and analgesic properties, there are other reported medical uses for Meperidine. It is used for chronic obstructive pulmonary disease, asthma, allergies, and fibromyalgia. Meperidine may also have significant interactions with any nonsteroidal anti-inflammatory drug (NSAID), including acetaminophen, aspirin, ibuprofen, naproxen, or trazodone. Meperidine, Meperidine, and other NSAIDs, may produce gastrointestinal side effects, such as nausea, vomiting, cramps, diarrhea, constipation, and sweating. It may also interact with antacids, acid suppressants, and calcium channels blockers, and cause acute liver toxicity.

Meperidine and other NSAIDs interfere with neurotransmitter receptor sites in the brain and cause Parkinson's disease, a disorder characterized by progressive loss of muscle co-ordination and speech. These drugs also reduce serotonin levels in the brain; consequently, they can promote symptoms of depression, anxiety, irritability, restlessness, impulsivity, difficulty sleeping, slurred speech, blurred vision, tremor, and nausea. It has also been found that these NSAIDs produce a rebound effect in patients taking monoamine oxidase inhibitors (MAOIs) to treat depression. Some research indicates that Meperidine, Meperidine, and other selective serotonin reuptake inhibitors (SSRIs) may increase the risk of suicidal thoughts and behavior in individuals already at increased risk for suicide.

Meperidine increase the amount of dopamine in the synapses and result in a euphoric "high," but the drug's effect on serotonin levels is less clear. Some studies suggest that, after treating an individual with a powerful opiate, the addition of Meperidine increases the amount of serotonin in the brain and decreases the amount of norepinephrine, a substance that is associated with mood and anxiety. The increased amount of dopamine may contribute to hallucinations and euphoria observed during the onset of opiate use, according to research. However, the decrease of serotonin may contribute to a reduction in nonrestorative sleep and an increase in poor quality sleep, according to some research. Meperidine can be purchased over-the-counter without a prescription. In certain countries, however, doctors must be specially trained to prescribe Meperidine to treat severe pain and cannot prescribe it for non-life-threatening acute pain.

Bell shaped pepper is a member of the Capsicum Baccatum species, which includes the Ají pepper

Image
  Bell pepper is the normal name for a cultivar gathering of the species Capsicum annuum, generally developed for their consumable, bell-shaped natural products, which are described by a polished outside of various shadings, including red, yellow, green, and orange. Bell peppers are now and then gathered with less impactful pepper assortments of Capsicum annuum known as "sweet peppers." There additionally are assortments of C. annuum that are impactful or hot, like the cayenne and jalapeño peppers. Bell shaped peppers contain a latent quality that disposes of capsaisin, the alkaloid that causes "hotness" in different plants in the family Capsicum. With their perfectly shaped structure and strikingly shaded outside of assorted shadings, bell peppers have been classified "the Christmas decorations of the vegetable world," to which is added a crunchy surface and tart taste (GMF 2008). Expanding on the variety in nature, bell shaped peppers mirror the notew...

Light Linear Alpha Olefins Are Produces through Oligomerization of Ethylene and by Fischer-Tropsch Synthesis

Image
  Light linear alpha olefins are commonly manufactured by two main routes: oligomerization of ethylene and by Fischer-Tropsch synthesis followed by purification. They are manufactured for a variety of reasons. One such reason is to use them as fabric and other textile applications in clothing manufacture. Various companies use ethylene trimerization process that produces only 1-hexene. In the U.S., Chevron Phillips Chemical Company, LLC, uses this process. Another commercial process, offered by a technology licensor IFP, dimerizes ethylene to high purity 1-butene. There are a wide range of applications for light linear alpha olefins . They are predominantly use in production of polyethylene, linear aldehyde, fatty acids, linear alcohols. Alpha olefins are also used in production of synthetic lubricant basestock and to make surfactants in a blend with higher linear alpha olefins. Another common use of light linear alpha olefins includes printing and apparel industries, agricul...

How is Tissue Banking Beneficial to People with Severe Morbidity, Chronic Diseases, and Organ Transplant Surgery?

Image
  Tissue banking alludes to the movement of gathering, stockpiling, handling, and circulation of transplantable human tissues. This industry fills in as a store of disposed of tissue and organs, both legitimately and wrongfully. These organs are here and there taken from criminal bodies or the dead groups of lawbreakers. Some of the time they may come from individuals who kick the bucket in emergency clinics. Whatever they are, every one of the organs are normally taken to a focal tissue bank which at that point discards them as indicated by neighborhood enactment. This interaction of collecting organs happens both when passing. There are numerous elements that decide when organs come from dead bodies. The fundamental one is that the organ must be dead and not yet deteriorating. Numerous organs must be eliminated from individuals who have passed on of sicknesses and ailments as these organs are not, at this point valuable. Some are even too harmed to possibly be helpful any longe...
