Affects The Dissolving Time In The Hydrochloric Acid

Hypothesis: It was hypothesised the colder the water is, the slower the tablet dissolves and the hotter the water gets, the faster the tablet dissolves. This is due to the particles heating up and getting excited thus separating the particles faster. It was suspected that the 20°C tablet in water would finish dissolving at 6 minutes, the 40° would dissolve at 4 minutes and the 50° would dissolve at 2 minutes. Also it was suspected that the 30°C tablet in water would dissolve after 4 minutes and the 60°C would finish dissolving after 1 minute.

Introduction: The purpose of this lab is to see how fast an Alka-Seltzer tablet dissolves in water when the surface area increases. Problem Statement: How does surface area influence the Alka-Seltzer tablet on how fast it can dissolve in water? Hypothesis: If the surface area increases then the time it takes to dissolve will decrease. Investigation Diagram (ID)

The intended use of medications is meant to improve a person’ health, it is very important the individual administering medication or self-medicating use the drugs correctly, by following the doctors’ instruction for the medication prescribed. Medication is given to diagnose, treat, and prevent illness. Medication can be very dangerous, which can potentially cause harm or even deaf if it’s not used properly.

The majority of medicines are formulated for oral administration. This means they are taken via the mouth, in the form of a tablet, capsule, liquid or suspension. These medicines come in a variety of

There are several types of medication, each has a purpose and function needed for their administration via the different routes.

A drug is a substance that causes changes in how your body functions. When you swallow a pill, the pill dissolves in your digestive system and the drug is absorbed into your bloodstream. Many drugs are designed to

The route in which a medication is administered is the ‘path’ that the drug/substance/fluid/poison is taken into the body these include:-

The National Prescribing Centre recognize some fundamental differences in the absorption, distribution and excretion of medicines between adults and children. The differences are published in the National Prescribing Centre’s bulletin, produced by

This is medication that is taken via the mouth. This can be in the form of tablets and capsules. If an individual finds it difficult to swallow tablets oral medication is also available in liquids, suspensions and syrups. Sublingual medications are for example when tablets are placed under the tongue to dissolve quickly.

Oral - medicines can be given orally in the form of capsules, tablets, liquids or powders.

Absorption – “How the drugs enter the circulation process through the body, and how they resist general breakdown by the stomach, liver, and the intestines”. Some of the factors that affect the absorption of drugs in the body is as follows, “acidity of the stomach, Physiochemical properties, Presence of food in the stomach or intestine, and Routes of administration”,

There are many different types of pills that humans use for various reasons, and each one is designed to cure or contain a certain problem or pain. This form of medication is usually compacted in a small tablet, sometimes with a coating on top, and meant for the user to swallow as a whole without allowing it to dissolve before entering the stomach. However, considering that people seem to want the fastest relief possible that they can get from their bodily ailments, the research question of this experiment was: Which class of pills dissolve the fastest?

According to Burchum and Rosenthal, pharmacokinetic is the study of drug movement throughout the body. When working in a Cardiac ICU, many of our patients required the use of digoxin for heart failure. Due to the narrow therapeutic index of digoxin, it had to be closely monitored. The end point for digoxin, is the heart muscle (myocardium). The trick is that we cannot take samples of the heart muscle to determine the level of digoxin. The good news is that we are able to measure its concentration through periodic blood levels. We then assume that as blood levels rose and fell within therapeutic, sub-therapeutic, or supratherapeutic values, so did the concentration level at the heart or its “distribution” into the cardiac cells. This

1. Oral and Intravenous are two different ways that a drug may be administered into the body. Oral drugs are absorbed by the intestinal lumen where they are transmitted to the liver to be metabolized, while Intravenous drugs are administered directly into the bloodstream. Because oral medication must go through the liver before being absorbed into the bloodstream, the level of bioavailability, or the amount/extent of the drug absorbed, is less than the medications that are administered directly into the bloodstream. Although intravenous administration allows for quicker absorption, oral medications are easier and more convenient for patients.

Pharmacology is the branch of medicine and biology that seeks to understand drugs and how they affect the body. It involves the analysis of how drugs interact with the biological function of the body and how these drugs react with each other, their natures, and their properties. All drugs are considered chemicals and when ingested into the body an affect from the drug takes place. According to Doweiko (1999), “A drug is essentially a foreign chemical that is introduced into the individual’s body to bring about a specific desired response. There are many forms of drugs and how these drugs are administered in the body determines the kind of result that will take place. The Central Nervous System, (CNS) plays a major role in how these
