APRN prescribing role - Prescriptive authority for nurse practitioners also regulates prescribing rights
beyond medications and controlled substances. These rights include therapeutic devices and services
and are outlined in state practice laws and regulations and include Durable Medical Equipment (DME)
such as wheelchairs, power scooters, hospital beds, portable oxygen equipment, handicap placards, etc.
and medical services such as Physical Therapy (PT), Occupational Therapy (OT), home health services,
etc. Prescriptive authority encompasses more than writing a prescription correctly. It requires
adherence to ethical guidelines to ensure that patients are safeguarded from harm. Ethical prescribing
starts with being well-informed about medications. Mechanism of action, efficacy, and safety are
important considerations, as are a patient's distinct needs and circumstances, including the number of
medications prescribed (Mitchell & Oliphant, 2016). Most patients receiving a prescription are taking
other medications, whether prescription or over-the-counter. Appropriate selection, dosing, and
duration of pharmaceutical agents are key to maximizing outcomes and minimizing adverse effects
benefits of full practice authority - Nurse practitioners have the autonomy to evaluate patients,
diagnose, order and interpret tests, initiate and manage treatments and prescribe medications,
including controlled substances without physician oversight
promoting positive outcomes through prudent prescribing practices - Administering medications and
prescribing medications are two distinct processes. Prescription writing requires prudent and deliberate
decision-making processes to maintain patient safety and reduce liability, including:

*documentation of a provider-patient relationship for the recipient of the prescribed medications
*documentation of a thorough history and physical examination for the recipient
*documentation of discussions regarding risk factors, side effects, or therapy options
*documentation of drug monitoring or titration plan, if applicable
*documentation of consultations, if any
avoidance of prescribing medications for self, family, or friends
Rational drug selection requires a logical approach that includes the formulation of a diagnosis based on
clinical reasoning and the selection and monitoring of the most appropriate pharmacological treatment
Considerations include: Cost, guidelines, availability, interactions, side effects, allergies, hepatic/renal
functions, need for monitoring, & special populations
Beer's Criteria - identifies drugs with a high likelihood of causing adverse effects in older adults.
Accordingly, drugs on this list should generally be avoided in adults older than 65 years except when the
benefits are significantly greater than the risks.
Pharmacodynamics - the study of the biochemical and physiologic effects of drugs on the body and the
molecular mechanisms by which those effects are produced
Pharmacokinetics - the study of drug movement throughout the body

Pharmacogenomics - the study of how genes affect a person's response to drugs. The purpose of this is
to combine the sciences of genomics and pharmacology to provide individualized, targeted, safe drug
therapies to patients
CYP450 inducers - Inducers are xenobiotics (medications and environmental agents) that elevate CYP450
enzyme activity by increasing enzyme synthesis. This action leads to additional sites available for
biotransformation. The increased number of sites enhances medication metabolism, decreasing the
concentration of the "parent drug" while increasing metabolite production.
Inducers = Increase medication metabolism
(Carbamazepine, Rifampin, Alcohol, Phenytoin, Griseofulvin, Phenobarbital, Sulfonylureas)
CYP450 inhibitors - Inhibitors are medications that inhibit the metabolic activity of one or more of the
CYP450 enzymes. Medications that inhibit an enzyme potentially slows that enzyme's activity or blocks
the activity required for the metabolism of other medications, thereby increasing the levels of
medications dependent on that particular enzyme for biotransformation. Inhibitors = decrease
medication metabolism (Valproate, Isoniazid, Sulfonamides, Amiodarone, Chloramphenicol,
Ketoconazole, Grapefruit Juice, Quinidine)
cultural influences in prescribing - The greatest concern surrounding race-based therapy has to do with
genetic variability. We know there is great diversity within and among racial groups; therefore, a "one
fits all" approach based on race is unwise. Still, we can use known associations to guide choices. For
example, differences in metabolism between people with East Asian and European heritage are
common. The provider can use this knowledge to guide initial dosing (with adjustment, as indicated
based on response) if genetic testing is not feasible or warranted
Polypharmacy: Definition, challenges, and outcomes - treatment with multiple drugs
greatly increases the risk for interactions. Some of these interactions are negligible, but some can have
life-threatening consequences. It is of crucial importance to ask the patient about all current drugs,
including over-the-counter (OTC) medications and other herbal preparations. Many patients do not

consider OTC or alternative pharmaceuticals as "medications" and may not mention them unless you
ask specifically.

Regulations of Controlled Substances - The U.S. Department of Justice Drug Enforcement Agency (DEA)
coordinates with local, state, and federal agents to reduce illicit drug use. The DEA enacted the
Controlled Substances Act (CSA) in 1970 to regulate drugs and other substances based on their potential
for abuse and dependency. Five schedules of controlled substances were created that are updated
annually. Classes of scheduled substances include narcotics, depressants, stimulants, hallucinogens, and
anabolic steroids. The DEA issues eligible providers with a registration number to write prescriptions for
controlled substances. Characteristics of a valid DEA number include:
-The first letter identifies the type of provider: A=before 1985; B=after 1985; F=after 2007; M=nurse
practitioner or physician assistant
-The 2nd letter the 1st letter of the provider's last name at the time of initial registration
Example: Tammy Greene applies for and receives a DEA number of MG2705208
M=nurse practitioner and G=Greene
Opioid Epidemic & Responsible Prescribing -
Opioid Use Disorder - a pattern of use that leads to significant impairment or distress. Typically, this
disorder is marked by unsuccessful efforts to reduce or control use resulting in the inability to fulfill
work, school, or home responsibilities. Opioid use disorder is different from drug tolerance and physical
dependence, which may also exist. Opioid use creates high levels of positive reinforcement, increasing
the likelihood of continued use. It is often a chronic lifelong disorder, leading to serious consequences
such as disability and death. Although it is similar to other substance use disorders, it has distinct
