6. Coumadin Classification: Vitamin K Antagonists Clinical uses and indications: The drug Coumadin is used to prevent and treat venous thrombosis, pulmonary embolism, and according towww.rxlist.com, “thromboembolic risks associated with atrial fibrillation and cardiace valve replacement.“ Coumadin also helps reduce the risk of death, myocaridal infartion, and strokes. (www.rxlist.com/coumadin) Normal dosages: Coumadin requires “individualized patient dosage“ (www.rxlist.com) as each patient’s…

Gabapentin and the Nmethyldaspartate antagonist, ketamine, are similar in improving early pain control and in decreasing opioid consumption.One key issue is its safety and tolerability, with psychotomimetic adverse effects being the major concern. In surgery with high risks of neuropathic pain…

8. Another important management step is to order a CT scan of the head to check for any underlying injury to the brain since the patient is non-responsive to pain stimulus, which indicates that the pain stimulus perceived by the sensory receptors that should normally travel up to the dorsal horn of the spinal cord and to the cerebral cortex where it is perceived as pain is not functioning properly. 9. Enhanced elimination techniques that could be applied to this patient include hemodialysis…

lack the ability to release vasopressin and they do not exhibit social memory, however social recognition was regained with the infusion of vasopressin into the brain. When a Long-Evans rat, which can produce vasopressin, was treated with a V1a antagonist social recognition was diminished, however an infusion into the lateral septum rescued this effect (Hammock 2006). These findings further tie vasopressin to actions and behaviors, which are needed for social communication whether in mating or…

The bacterial cell has a protein, which is an enzyme that makes that hormone molecule. The cells then grow, releasing that molecule into the environment. The bacteria have a receptor on their cell surface that fits with that molecule it produced. When the molecule increases to a certain amount, it locks down into that receptor and information comes into the cells that tells the cells to turn on this collective behavior of making light. The importance of the glowing bacteria, is all bacteria use…

Eight o’ Clock: The Effects of Dependence on America’s Most Popular Drug Each year, countless money and time is employed in educating American children about the dangers of drugs. They are taught about their prevalence, as well as the risks involved with their uses and abuses. One of the most prevalent drugs on the market is a certain psychoactive drug, a stimulant classified with cocaine and nicotine for its properties. Largely imported from countries like Brazil, Indonesia, and Colombia,…

kappa-opioid receptors, thus inhibiting and modulating pain signals.88 Morphine is a pure mu-opioid receptor agonist with a great hypoalgesic effect and very used in veterinary medicine.89 Since pure mu-agonist opioids cause addiction in humans, the use of these opioids is strictly controlled, which may limit their use. Butorphanol is a kappa-opioid receptor agonist and a mu-antagonist, which limits its analgesic properties and efficacy.89 Buprenorphine is a partial mu-opioid receptor…

Heart failure (HF) is a complex and progressive clinical syndrome that can result from any structural abnormality or functional impairment of ventricular filling or ejection of blood.1 The term “heart failure” is preferred over “congestive heart failure” because some patients may show no signs or symptoms of volume overload.1 An estimated 5.1 million Americans >20 yrs of age have HF based on NHANES 2007-2010 data.2 By 2030, projection show that the prevalence of HF will increase 25% from…

Pain can be an uncomfortable sensation that surges through our body that can range from mild to very painful. Although we don’t like to feel pain, it is a necessary occurrence in order to signal to the brain that we need to get away from the thing that is causing us the pain. In the previous paper, the journey from the nerves, to the spinal cord, and lastly to the brain was discussed. Information was sent through a multitude of action potentials from the afferent neuron to the 2nd-order neuron…

persistent or paroxysmal atrial flutter who are in sinus rhythm or undergoing cardioversion after initiation of the drug. Dronaderone (Multaq) is sodium and potassium ion channels blocker, like amiodarone. It is also an alpha and beta adrenergic receptor antagonist. Dronaderone is a benzo furan derivative like amiodarone, with the addition of methyl sulfonamide group which reduces the lipophilicity. Lipophilicity reduces the drug to cross blood brain barrier, and this has shown in less adverse…
