As yоu cоnduct аn intrаоrаl exam on your patient, you notice a 4 mm erythemic ulcer on the floor of the mouth. Your patient said the sore had only been there for two days. You document the details of the exam in your Dentrix clinical notes. When should you have your patient back to determine if you need to refer her for a biopsy?

Anоther clаssificаtiоn system оf note is the Drug Schedule thаt is a product of the US government. We cover the US Drug Schedule in some other classes. Personally, I don't think it makes much sense and after this lecture, won't reference it. However, it is our government's official classification system and it is important to be aware of how it identified common drugs of use. This system identifies five classes of drugs. Schedule One being identified as drugs with a significant abuse potential and no medical use (dangerous), and then through Schedule Five which are considered to have strong medical efficacy and no risk of abuse (safest). I have provided a table, below, that provides a definition and some examples of each schedule. See if you can find any odd placement of some of these drugs.  Schedule 1 Schedule I drugs, substances, or chemicals are defined as drugs with no currently accepted medical use and a high potential for abuse. Some examples of Schedule I drugs are: heroin, lysergic acid diethylamide (LSD), 3,4-methylenedioxymethamphetamine (ecstasy), methaqualone, and peyote Schedule 2 Schedule II drugs, substances, or chemicals are defined as drugs with a high potential for abuse, with use potentially leading to severe psychological or physical dependence. These drugs are also considered dangerous. Some examples of Schedule II drugs are: combination products with less than 15 milligrams of hydrocodone per dosage unit (Vicodin), cocaine, methamphetamine, methadone, hydromorphone (Dilaudid), meperidine (Demerol), oxycodone (OxyContin), fentanyl, Dexedrine, Adderall, and Ritalin Schedule 3 Schedule III drugs, substances, or chemicals are defined as drugs with a moderate to low potential for physical and psychological dependence. Schedule III drugs abuse potential is less than Schedule I and Schedule II drugs but more than Schedule IV.  Some examples of Schedule III drugs are: products containing less than 90 milligrams of codeine per dosage unit (Tylenol with codeine), ketamine, anabolic steroids, testosterone, and marijuana (as of 2024) Schedule 4 Schedule IV drugs, substances, or chemicals are defined as drugs with a low potential for abuse and low risk of dependence. Some examples of Schedule IV drugs are: Xanax, Soma, Darvon, Darvocet, Valium, Ativan, Talwin, Ambien, Tramadol Schedule 5 Schedule V drugs, substances, or chemicals are defined as drugs with lower potential for abuse than Schedule IV and consist of preparations containing limited quantities of certain narcotics. Schedule V drugs are generally used for antidiarrheal, antitussive, and analgesic purposes.  Some examples of Schedule V drugs are: cough preparations with less than 200 milligrams of codeine or per 100 milliliters (Robitussin AC), Lomotil, Motofen, Lyrica, Parepectolin   Our textbook provides classification by these categories: Purpose of Use- Why someone would take them (drugs used for pain relief, drugs used to work to work longer, to build endurance in sports) Chemical, Trade, or Street name Chemical names describe the molecular structure Trade names are the manufacturer's name, like Xanax or OxyContin Street names (this seems self explanatory...) Effects- This is what we will use for this course. It groups psychoactive drugs with similar effects together: Stimulants, as example. (The text's title is the clue. It uses Uppers, Downers, and All-Arounders as its classification system). We dedicate one or more modules to each of these during the semester.

Pleаse reаd ch.1, sectiоn 1.1 thru 1.8 befоre cоntinuing... Pleаse note that the written lectures for this course come directly from Uppers, Downers, and All-Arounders, 8th edition, by Darryl Inaba and William Cohen. Any additional works are cited in the text. A psychoactive drug is any substance that directly alters the normal functioning of the central nervous system (CNS).  These are the substances we are covering in this course. We also expand on this definition to include some compulsive behaviors like gambling, sex, or internet gaming when learning about physiology of psychoactive substances. These compulsive behaviors are often referred to as process disorders.  Classification of Psychoactive Drugs The World Health Organization (WHO) panel of experts understood, their definition of drug is very broad. To make the definition useful for research and practical purposes, it is necessary to order the substances that fit the definition of drug into smaller categories. Pharmacologists have done this with their many systems for classifying drugs. These classification systems have been based on the primary properties of drugs to communicate a drug’s nature and the ways it can be used. Following are some of the major ways of classifying drugs: By origin. An example is drugs that come from plants, such as the opiates, which are derived from the opium poppy. The “pure” (non-synthetic) opiates include compounds such as morphine and codeine. Heroin, which is a semisynthetic compound, is often called an opiate drug. Because this classification distinguishes only the source of the drug, a given drug class may include many drugs that have different chemical actions. By therapeutic use, or according to similarity in how a drug is used to treat or modify something in the body. For example, with this system, amphetamines are called appetite-suppressant drugs. Note that the reasons some drugs are used can be much different from their therapeutic effects. Amphetamines are often used non-medically because of their stimulant effects. Similarly, morphine may be used medically as a powerful painkiller, but street users most commonly take morphine for its euphoric effects.  By site of drug action, which pertains to where in the body the drug is causing physical changes. For example, alcohol is often called a depressant drug because of its depressant action on the central nervous system (CNS). Conversely, because of its CNS stimulant properties, cocaine is often called a stimulant drug. The utility of this system is limited when a drug affects several different body sites. One example is the CNS stimulant cocaine, which also has local anesthetic (pain-reducing) effects. Furthermore, drugs that differ widely in chemical structure or mechanisms of action may affect the same body site. By chemical structure. For example, the barbiturates (such as phenobarbital, amobarbital, and secobarbital) are synthetic compounds derived from the chemical structure of barbituric acid, the synthetic compound that forms the chemical base for barbiturate drugs. By mechanism of action, which means how a drug produces its drug effects. This is a good system in principle, and ongoing research in pharmacology is directed at specifying the mechanisms of action of an increasing number of drugs.
