Altered Drug Response
The response to drug treatment seen in the elderly is very different to that seen with younger patients. Altered drug response in the elderly is often associated with changes in the body that result in modification to the pharmacokinetics of the drugs in older people. Absorption changes result from Morphological changes to the gastrointestinal mucosa. GI function changes have an effect on enzymatic breakdown, dissolution, and drug ionization which then leads to alterations in oral drug absorption. Intestinal absorption of some drugs is delayed due to reduction rate in gastric emptying. Another example is Elimination changes, which are caused by altered pharmacokinetics in renal function. Diminished renal and hepatic function can have

    The plasma peak time of these drugs ranges between 1-2 hours with Empagliflozin peak level at 1.5 hours. Studies have shown a slight reduction in circulation of Empagliflozin after the consumption of a high-fat meal. Dapagliflozin has the highest bioavailability in this class of drugs at 78 percent and the bioavailability of Canagliflozin is 65 percent. The excretion of the drug is through the urine and feces by way of the O-glucuronidation pathway. The half-life for Canagliflozin is dose dependent and ranges between 10-13 hours. The half-life of Dapagliflozin is 12.9 hours and the half-life of Empagliflozin is between 10-19 hours.

    The idea that your imagination is a key determining factor in accepting your uncertain future is supported but also refuted in the short story On the Rainy River. The main character, Tim O'brien provides strong evidence for the strength of one's imagination through the visual representation he provides of the slaughterhouse where he works and the way he imagines disappointment and disgust those back in his home would feel. However, at the end of the story it becomes clear that regardless of one's imagination or will, the future is set in stone and the path you walk is already set in stone.…

    Case 6.4 Drug Dilemmas

    • 1435 Words
    • 6 Pages

    The cost of new medical drugs seems to be accepted by many people who use them. These pharmaceutical companies increase their profits more and more each year because many people assume that it does cost a lot of money for research and development. Where in reality, they are only spending about 15% of their profit margins on research and development alone. A huge percentage of these drugs are actually tested in other countries where people are more willing to do trials with these drugs because they cannot afford them. Not only are there more people who are more willing to try them, but also there is less regulation and oversight when it comes to testing. Conducting these clinical trials overseas not only saves money, but it also bypasses the requirement of the FDA approval before any human testing can be performed. Using Kant’s theory for determining what actions are considered morally right and wrong, we can look into his Categorical Imperatives. The first CI states, “Act only according to that maxim by which you can at the same time will that it would become a universal law”. (McPhee 1) The second CI states, “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end”. (McPhee 1) According to this case, we may now bring up several morally questionable actions that these pharmaceutical companies are doing. Is it okay for these companies to sell medical drugs at such a high cost? Should these pharmaceutical companies have a moral obligation to make drugs available to the country in which they perform research and development? Are these test subjects being exploited and being taken advantage of? Should pharmaceutical companies do their testing overseas? Now that we understand the situation at hand, we may come to believe that the pharmaceutical companies are acting in an immoral way according to the CI's. We can look further in…

    Drug testing? Insane, outrageous, and wasteful. The issue is whether or not welfare recipients should be drug tested and clean in order to receive funding.

    While the text states that taking "drugs won’t enhance creativity", I disagree, because for one, some of our best music comes from the major drug using era known as the 60’s, 70’s, & 80’s. All joking aside, I mainly just disagree with this statement in particular because I think it could have been worded a bit differently and really define what they mean by a “drug” especially because I think addiction affects everyone. What people think about when they see the word can be anything (usually derived from their own experience perhaps with loved ones who were addicted) the thought of what a drug is (as well as the thought of what addictive behaviors and patterns are) may vary from person to person and it happens to do with and can be a many assortment of things that make up a part of everyone’s life. It’s just when a person starts to do something obsessively and excessively, do things with no regard of or for their own life, and also having and feeling like they cannot control themselves because their life is falling into in a downward spiral or they are already feeling the undertow. -Intended to be associated with being a part of (in) and an album from two very talented bands. Although drugs affecting creativity is not supportive in either argument, per say, it still effects everyone in one way or another whether to inspire a career or destroy a life. While the text states that, “you don’t have to be a genius to be creative,” even genius’s fall victim to drug abuse and one perspective (although no one has answered this question satisfactorily), also from the text, suggests that drugs harm creativity because, “their addiction reduces judgment, and the activities they provoke are hallucinatory rather than illuminating.”-Brewster Ghiselin The bottom line is, that if you have lost control in whatever aspect of your life, drugs or not, the journey (experience) in recovering complete control will enlighten your “creative discipline” so the more you are in control of,…

    Tranexamic acid is a synthetic derivative of the amino acid lysine. It exerts its antifibrinolytic effect through the reversible blockade of lysine-binding sites on plasminogen molecules. Anti-fibrinolytic drug inhibits endometrial plasminogen activator and thus prevents fibrinolysis and the breakdown of blood clots. The plasminogen-plasmin enzyme system is known to cause coagulation defects through lytic activity on fibrinogen, fibrin and other clotting factors. By inhibiting the action of plasmin (finronolysin) the anti-fibrinolytic agents reduce excessive breakdown of fibrin and effect physiological hemostasis. |…

    Drugs Negative Effects

    In drug-related prosecutions, the State bears the burden not only of proving the elements of the offenses of sale and possession of shabu under Republic Act No. 9165, but also of proving the corpus delicti, the body of the crime. “Corpus delicti has been defined as the body or substance of the crime and, in its primary sense, refers to the fact that a crime has been actually committed. As applied to a particular offense, it means the actual commission by someone of the particular crime charged. The corpus delictiis a compound fact made up of two (2) things, viz: the existence of a certain act or result forming the basis of the criminal charge, and the existence of a criminal agency as the cause of this act or result.” The dangerous drug is itself the very corpus delicti of the violation of the law prohibiting the possession of the dangerous drug. Consequently, the State does not comply with the indispensable requirement of proving corpus delicti when the drug is missing, and when substantial gaps occur in the chain of custody of the seized drugs as to raise doubts on the authenticity of the evidence presented in court.…
