1. What are the requirements for dispensing schedule II and III prescriptions? Name some examples of each. Schedule II can only be prescribed in person, unless it’s an emergency. Schedule II’s dispensing is very strict since it has a high possibility of abuse. An example of schedule II would be morphine, fentanyl and hydromorophone. Schedule III has a moderate potential for abuse. Unlike schedule II which doesn’t have refills on prescriptions, Schedule III can be refilled five times within six months. This has to be approved by a physician. Examples of schedule III are anabolic steroids and codeine with aspirin or acetaminophen. Internet Research

2. Explain the concepts receptor, agonist, and antagonist. * Receptor: it is a specific protein molecule that communicates with a messenger. The receptors are on the surface, or sometimes within the cell. They work simultaneously with messengers. * Agonist: it enhances natural reactions of the body. It can bind with a receptor, in which gives the same similar cellular response if the messenger and receptor binds. * Antagonist: drugs that does the opposite of the agonist. It will bind with the receptor site, and it will prevent the response, and also it will inhibit the natural reaction as well. 3. Define half-life. If a drug’s half-life is six hours, how long would it take to remove the drug from the body. * Half-life: it is the estimated time that it takes to eliminate drugs from the body. It is written in T1/2. If the drug’s half-life is six hours, it would take 30 hours to 42 hours to eliminate the drug.

4. List causes for and discuss altered drug response in the elderly. * There are 4 main changes that causes altered drug response in the elderly. Absorption changes affect the breaking down of the drug. It makes it harder as they age to consume and absorb certain drugs. Distribution changes are changes in the body composition of an elder. This affects the main distribution of the drugs throughout the whole body. Elimination changes are mainly caused by a weakened kidney. In order to eliminate certain drugs, a healthy kidney is needed. Metabolism changes such as impaired metabolism can also cause altered drug response. All of these changes in an elderly person can affect their drug response, which results to an altered drug response. 5. List and explain three things to keep in mind when dosing a child. * Making sure that the drug dosage is mainly appropriate for the child’s age. * Carefully check all computations that involve the height and weight of a child. * Take time to reevaluate the intervals that are given to all the dosages.
