Study Notes

Drug Names and Classifications

  • Chemical names are also known as scientific names
  • Chemical names describe the drug's molecular structure
  • IUPAC names are the most important naming system
  • Generic names are used instead of brand names
  • Proprietary names are another name for brand names
  • Trademark names are brand names
  • Copyright names are brand names
  • Therapeutic action, organ systems, mechanism of action, and chemical properties are used to classify drugs based on ATC system level 1
  • Chemical components are classified based on level 5 of ATC system

Pregnancy Categories

  • Category X drugs have demonstrated fetal risks, and there are no benefits that outweigh the risks to the fetus.
  • Category N drugs do not have established categories.
  • Category A drugs have demonstrated no risks to the human fetus based on trials.
  • Category D drugs have demonstrated risk to the human fetus, but the benefits outweigh the risk to the fetus

Drug Schedules

  • Schedule I drugs have high potential for abuse and addiction, and are only safe for medical use under strict supervision.
  • Schedule II drugs are safe for medical use under strict medical supervision

LASA Medications

  • LASA medications have similar physical structures, packaging, drug names, and similar spellings, or pronunciation.
  • Illegible writing, incomplete knowledge of drug names, differences in clinical uses, and similar packaging/labels are risk factors for medications.
  • Tall man lettering is a strategy used to reduce errors in the procurement of LASA medications.
  • Writing parts of the medication name in upper case helps differentiate LASA medications.

Metric system

  • The metric system is the legal system of measurement in the U.S.
  • It uses the decimal system
  • It includes gram, meter, and liter

Drug Risk Management

  • The FDA considers a drug to be safe if the benefits of using it outweigh the risk to patients.
  • At the assessment stage of the drug risk management process, benefit-risk decisions are made to ensure patients' safety.

Drug Classification and Metabolism

  • High-alert medications require monitoring as they have a narrow therapeutic margin, and can cause serious adverse effects with minimal dosage change
  • The risk evaluation and management strategy (REM) is used to monitor high-alert drugs
  • First-order kinetics describes the proportional relationship between the drug's rate of metabolism and the amount of unmetabolized drugs left in the body.
  • Phase I metabolism encompasses reactions like hydrolysis and oxidation.
  • Phase II metabolism includes reactions such as glucuronidation and conjugation
  • Renal excretion pathways are a primary means of drug removal
  • Drugs are categorized based on their risk factors, potential benefits, and contraindications

Drug Formulation and Administration

  • Suspensions are heterogeneous mixtures, not filtered, and use low-speed mixers for preparation
  • Solutions require careful consideration of solubility characteristics of each active ingredient
  • Emulsions are mixtures of immiscible liquids. Oil-in-water emulsions are not greasy, and water-in-oil emulsions are usually for oral use.
  • Creams are for topical use
  • Ointments often include insoluble substances, and are water-based.

Drug Interactions

  • Drug interactions (e.g., with ibuprofen, aspirin, serotonin reuptake inhibitors [SSRIs], and nonsteroidal anti-inflammatory drugs [NSAIDs]) can affect drug efficacy and safety.
  • Interactions that increase the risk of gastrointestinal bleeding need to be considered.

Drug Distribution

  • Multiple factors affect drug distribution rates, including permeability of membranes, tissue binding, receptor affinity and regional pH.

Drug Calculations

  • Various rules (Clark's Rule, Young's Rule) are used to calculate appropriate drug dosages for children based on their weight or age, comparing to adult dosages.
