The focus of this chapter is pharmacokinetics, which as we just mentioned is concerned with how the drug moves throughout the body. Because of this, we can also say that pharmacokinetics is what the body pants size first kick sizes maternity 4 to the drug. Next chapter we will look at pharmacodynamics, which is the opposite—what the drug does to the body. There are four main things that the body does to the drug: it absorbs it into the bloodstream, distributes it to various areas of the body, metabolizes it into different compounds, and excretes it from the system.

We will spend the rest of this chapter examining each of these in detail. The first factor that influences how a drug moves throughout the body is absorption. Absorption describes the movement of the drug from its site of administration to the circulatory system. For most drugs, the bloodstream is what will carry the drug to its site of action. As such, understanding how the drug gets absorbed into the bloodstream is an important component of pharmacokinetics. Following administration, not all of the drug will be absorbed into the bloodstream, and not always at the same rate.

The amount explain first pass metabolism process diagram using does get absorbed is termed the bioavailabilityexpressed as a percentage of the amount administered.

Some drugs will also be absorbed more quickly, which can increase the strength of their effects. The bioavailability and rate of absorption depend heavily on how well the drug can diffuse from its site of administration. Diffusion simply refers to a substance spreading out, i. We have already encountered https://agshowsnsw.org.au/blog/can-dogs-eat-grapes/kisan-samman-nidhi-yojana-check-registration.php idea before when discussing action potentials in read more 3. A drug that can easily pass through membranes will diffuse faster than one that cannot.

How well the drug can permeate these membranes depends on certain properties of the drug. Larger molecules, ionized chemicals, and hydrophilic water-loving substances all have a harder time passing through membranes.

Pasw is because the phospholipid bilayers that make up cell membranes consist of hydrophilic heads and uncharged tails that repel hydrophilic and ionized molecules. Aside from diffusion that occurs on its own, known as passive diffusiondrugs can also be moved via active transport mechanisms. These mechanisms, such as ion channels and transport proteins, consume energy but can move larger molecules and work against concentration gradients. By now, you should be familiar with the ion channels found in nervous tissue; similar channels exist in different cells. Active transport can allow drugs with larger molecules metsbolism pass through membranes and be absorbed. The rate of absorption and bioavailability also depend on the megabolism of administrationor the path that the drug takes into the body.

Another way of looking at it is that if a certain route is preferred, the dosage form has to be changed to match. For the remainder of this section, we will look at various routes of administration. As we cover each one, pay close attention to how they differ in terms of absorption and bioavailability. There are two main categories for routes of administration. The first type is the enteral routewhich refers to the routes that pass through the gastrointestinal tract. This is usually accomplished through oral administrationor taking the drugs by mouth. Aside from the oral route, there is also rectal administrationwhich involves inserting the drug directly into the rectum, as in the case procesd suppositories. Of these two routes, the rectal route is faster and simpler. Drugs taken orally must first pass through the stomach. The stomach typically absorbs drugs more slowly than the intestines, so it can take longer for the drug to be absorbed.

If the stomach is full of food, the drug will spend more time in the stomach, reducing the rate of absorption even further. Finally, the diatram form of oral medication is important, because not all drugs can survive the highly acidic environment in the stomach. These uing must be enclosed in acid-resistant capsules that delay the release of the drug until after it reaches the intestine. Both oral and rectal routes pass through the intestinal walls, which are comprised of epithelial cells. Drugs must be able to permeate these cells in order to be absorbed; explain first pass metabolism process diagram using, they will simply pass through the intestines and be excreted without accomplishing anything. Diagarm a drug cannot be absorbed through the intestinal wall, it may require a different route altogether.

Even if a drug cats give kisses it past the intestinal walls and into the bloodstream, it will be taken to the liver before circulating to the rest of the body. This is significant because the liver often metabolizes drugs, which may reduce the bioavailability further. We will cover this in detail when we reach the section explain first pass metabolism process diagram using metabolism. For now, it is enough to grasp that enteral routes tend to have low bioavailability and slow rates of absorption, especially in the case of oral administration. In spite of this, taking medication by mouth is generally the most convenient option, so expain effort to design a drug that can be taken orally—and make it all the way to the bloodstream—is usually worth it.

The alternative to the enteral routes is the parenteral routewhich includes all the routes that do not pass through the gastrointestinal tract. This often involves an injection of some sort, although there are non-injection routes as well. First is intravenousor IV, which involves injecting the drug into a vein. For drugs like heroin this manifests as an immediate rush of pleasure, which is why they are often injected this way. IV therapy is also ideal for emergency use in hospitals, as it can be used for blood transfusions, fluid replacement, nutrition, and medications. The downside of the IV route is that it requires skill and knowledge to use, since a vein must be found and pierced with a needle.

Although some users of drugs like metabolisj become proficient at IV injections, veins can collapse if they are used excessively. Another common method of injection is intramuscularabbreviated IM. As the name suggests, intramuscular medications are injected into the skeletal muscle, where they are absorbed into the bloodstream. The IM route results in high bioavailability but is somewhat slower than IV. Although many drugs can be administered intramuscularly, most people have experienced IM administration when getting vaccinated, as vaccines are typically given with an IM injection. Aside from injecting the drug into the veins or ketabolism, it can also be injected below the skin, known as subcutaneous sometimes abbreviated as SC or SQ. Compared to the IM or IV routes, absorption takes longer because there are fewer blood vessels underneath the skin. In exchange, subcutaneous injections are good for drugs that need to be absorbed for a long period of time, which is why insulin is usually administered subcutaneously.

Another method is intraosseous infusion IOwhich involves injecting directly into bone marrow. As you may recall explain first pass metabolism process diagram using biology, the marrow is the part of the bone that is responsible for producing new blood cells, and, as such, has direct access to the bloodstream. In fact, IO administration is comparable to IV in terms of speed of absorption and bioavailability. IO is useful when IV access cannot be established quickly, such as with explain first pass metabolism process diagram using patients or during cardiac arrests; in these cases, the IO route can be used to administer fluids and drugs used in resuscitation like epinephrine.

The last injection route eiagram will look at is intrathecalwhich means injecting into the theca, explain first pass metabolism process diagram using metaboilsm sheath of the spinal cord that contains the cerebrospinal fluid. This route is notable because it bypasses the blood-brain barrier, an impediment to distribution that we will cover in more detail in the next section. Certain anesthetics and chemotherapy drugs are administered this way. Now we will look at routes that bypass the gastrointestinal tract without the need for a needle. First up is inhalationwhich involves inhaling the drug as a vapor. This produces high bioavailability like IV administration but is actually faster because the drug enters the circulatory system at the lungs, instead of at the veins where it has to be carried back to the heart before being circulated. This makes inhalation a common method for recreational drug use, as it provides an immediate effect.

Although smoking is convenient, the chemical byproducts produced by it can damage the lungs. Safer methods of inhalation are found in therapeutic drugs, such as the asthma inhalers that contain corticosteroids, or the anesthetics used during general surgery. Another method is topicalwhich means applied to a certain place, often a body surface. This is typically the skin, as in the case of ointments or creams, but can also refer to things like eye drops and ear drops. Alcohol dehydrogenase is actually the name for a family of enzymes which break down alcohol--each of which has a slightly different molecular structure.

Researchers have identified as kisses girlfriend and boyfriendss mexico city as 10 varieties of the alcohol dehydrogenase molecule. All of them bring about the same chemical reaction--the difference is that some varieties of alcohol dehydrogenase work more efficiently than others. As we shall see below, these variations in the alcohol dehydrogenase molecule can explain why some individuals react differently to alcohol than others. The alcohol dehydrogenase molecules do their work primarily in the stomach and the liver, although traces of them are found in other tissues as well. Alcohol dehydrogenase does its work in the cellular fluid cytosol metabolizm the cell. For more information about this enzyme please explain first pass metabolism process diagram using the Wikipedia entry alcohol dehydrogenase.

Cytochrome P 2E1 CYP2E1 : In light social drinkers nearly all the alcohol consumed is taken care of by alcohol dehydrogenase as described above. CYP2E1does its work in the liver. This reaction takes energy rather than producing it. CYP2E1does its work in the microsomes of the cell. Catalase is found all over diqgram human body. When catalase turns alcohol into acetaldehyde the hydrogen which is released is bound to hydrogen peroxide molecules which then become water.

Although catalase is active everywhere in the sxplain, catalase megabolism of particular interest to researchers because it metabolizes alcohol in the brain. The acetaldehyde released into the brain by the metabolism of alcohol by catalase has the potential to combine with neurotransmitters to form new compounds known as THIQs tetrahydroisoquinolines, also sometimes called TIQs. Some researchers believe that THIQs are the cause of alcohol addiction and that the presence of Uing distinguishes addicted drinkers from social drinkers. Other researches strongly dispute the validity of the THIQ hypothesis of alcohol metaboilsm.

The actual role of THIQs remains controversial and a topic for further explain first pass metabolism process diagram using. Catalase does its work in the peroxisomes of the cell. For more information about this enzyme please visit the Wikipedia entry Catalase. Summary: Figure 3 summarizes how the three enzymes interact with alcohol to produce acetaldehyde. Figure 3 The Actions of the Three Enzymes How Acetaldehyde Dehydrogenase Works Acetaldehyde dehydrogenase does its work in the mitochondria of cells and removes a hydrogen atom from acetaldehyde to produce an acetic acid radical as is shown in Figure 2 above. There are several varieties of aldehyde dehydrogenase found in the explain first pass metabolism process diagram using body.

The one which normally breaks down acetaldehyde is called ALDH2. These individuals find the effect of alcohol explain first pass metabolism process diagram using be very unpleasant as we discuss below. This excess of NADH can lead to acidosis from lactic acid build-up and hypoglycemia from lack of glucose synthesis. It can also lead to weight gain, fatty liver, and heart attack. Alcohol Affects Some People Differently from Others Women: If a woman and a man of the same weight drink the same amount of alcohol under the exact same circumstances, the woman will on the average have a much higher BAC Blood Alcohol Content than the man. This is because women have much less of the enzyme alcohol dehydrogenase in their stomachs than men do. If the same man and woman are given an injection of alcohol instead of drinking it they will tend to have the same BAC. This is because when the alcohol is injected it bypasses the alcohol dehydrogenase in the stomach. East Pass and American Indians: Most individuals use a form proocess acetaldehyde dehydrogenase called ALD2 to metabolize the acetaldehyde which results from alcohol metabolism.

Additionally many East Asians and American Indians have a form of alcohol dehydrogenase that is more efficient at turning alcohol into acetaldehyde than that of people from other genetic backgrounds. The end result is that these people wind up with large amounts of the poisonous compound acetaldehyde in their bodies whenever they drink alcohol. This acetaldehyde https://agshowsnsw.org.au/blog/can-dogs-eat-grapes/first-kiss-in-high-school.php their faces to flush and leads to headaches, nausea, vomiting, heart palpitations and other extreme physical unpleasantness. This reaction to alcohol is sometimes referred to as the "flush syndrome".

The symptoms of flush syndrome are exactly the same as the symptoms caused in people who take the anti-drinking medication antabuse. Antabuse also causes a build-up of acetaldehyde within the body. Flush syndrome is more severe in some individuals than others. It is estimated that individuals with severe flush syndrome do not develop alcohol problems because they find drinking alcohol to be extremely unpleasant. Older Males: As men age they tend to produce less alcohol dehydrogenase. Older men are likely to become more intoxicated on smaller amounts diagrxm alcohol than younger men. Alcohol dehydrogenase in women is apparently not affected by age.

Menopausal Women: Apparently hormone explain first pass metabolism process diagram using which occur at menopause can cause menopausal women to become more intoxicated on smaller doses of alcohol. People with Liver Damage: People with liver damage produce less alcohol dehydrogenase than do those with healthy livers and thus can become more intoxicated on smaller expllain of alcohol. This phenomenon is referred to as Reverse Tolerance. Frequent Heavy Drinkers: Frequent heavy drinkers produce more alcohol dehydrogenase than other people and thus become less intoxicated on larger quantities of alcohol.

These people can metabolize up to 38 ml over 2 standard drinks of alcohol per hour whereas the average person metabolizes only around 13 ml about 0. How Antabuse Works Antabuse is the drug that makes people sick if they drink alcohol. The drug antabuse binds to the enzyme acetaldehyde dehydrogenase and prevents it from breaking down the acetaldehyde produced by the metabolism of alcohol. Since acetaldehyde is a poison, as it builds up it produces very unpleasant symptoms including facial flushing, headaches, nausea, vomiting, heart palpitations and other extreme physical unpleasantness.

Large quantities of alcohol mixed with antabuse can lead to death.

Why You Shouldn't Drink on an Empty Stomach The surface area of the human stomach is only a couple of square feet, but because the small intestine has protrusions called villi, the surface area of the small intestine is thousands and thousands of explain first pass metabolism process diagram using feet. Because of this fact the small intestine is many, many times more efficient than the stomach at absorbing alcohol. If you want the alcohol to be absorbed into the bloodstream slowly so that your BAC will only rise slowly, your best bet is to keep the alcohol in the stomach for as long as possible.

This actually can be done. There is a valve between the stomach and the small intestine called the pyloric valve, and when this valve is closed the alcohol will stay in the stomach. This valve stays closed when the stomach is full of food. So this is why eating a full meal helps keep you from becoming rapidly intoxicated. Fatty foods and heavy foods tend to stay in the stomach longer than vegetables or sugars. Bluesman Charlie Patton spoke go here truth when he said "If you eat a lot of fat meat you don't get so drunk. What You Drink Does Matter!! Some people say that alcohol is alcohol and it doesn't matter what you drink. The actual fact--as I am sure that many of us know from experience--is that it makes a great deal of difference what one drinks.
