_____________________________________________________________________________________
What is part A of the Texas BON rule 222.8 Authority to Order and Prescribe Controlled Substances?
Comply with all federal and state laws and regulations including United States Drug Enforcement
Administration.
NEED DEA #
What is part B of the Texas BON rule 222.8 Authority to Order and Prescribe Controlled Substances?
Orders and prescriptions for controlled substances in Schedules III through V may be authorized,
provided certain requirements are met.
What is part C of the Texas BON rule 222.8 Authority to Order and Prescribe Controlled Substances?
Orders and prescriptions for controlled substances in Schedule II may be authorized only in hospital
setting, admitted to hospital, in ED, or terminal illness (hospice).
What is the Prescription Monitoring Program of Texas?
Collects and monitors prescription data for all Schedule II, III, IV, and V Controlled Substances (CS)
dispensed by a pharmacy in Texas or to a Texas resident from a pharmacy located in another state.
When do pharmacies need to report dispensed controlled substance records according to the PMP?
No later than next business day.
What does the PMP require as of 3/1/2020?
Pharmacists and prescribers (other than a veterinarian) will be required to check the patient's PMP
history before dispensing or prescribing opioids, benzodiazepines, barbiturates, or carisoprodol.
What is the National Provider Identifier (NPI)?
Consists of 10 digits, and each health care provider and practitioner who bills for services must obtain
one.
What are Pharmacodynamics?
,Relationship between the drug concentration and the patient's response to the drug... it is what the
drug does to the body.
What is the variation in drug response explained by?
By variations in environmental and genetic factors.
How do most drugs work?
By binding to receptors.
What is the receptor theory?
Drugs act by binding to receptors.
What happens once drugs are bound to receptors?
Initiates biochemical & physiological changes characteristic of the response to the drug, hormone, or
neurotransmitter.
What does the receptor theory require?
Affinity and efficacy.
What is affinity?
Attraction between a drug and its receptor.
What is efficacy?
Ability of a drug to activate a receptor and produce an effect.
What is the lock and key mechanism of receptors in receptor theory?
The drug molecule must "fit" into the receptor like a lock and key mechanism (not always this simplistic).
What is the dose-response curve?
Intensity of response produced by a drug is related to the number of receptors occupied thus is
proportional to the dose/ concentration of the drug.
What occurs at 50% max response during the dose-response curve?
50% of the max response occurs at a dose/ concentration at which a drug occupies 50% of its receptors.
What happens if a dose is below the curve in dose-response?
Do not produce pharmacological response.
What happens if a dose is above the curve in dose-response?
,Do not produce additional pharmacological response, may have toxicity.
What is efficacy in regards to dose-response?
Maximum effect that a drug can produce regardless of dose (e.g., drugs used to treat mild pain will not
work on severe pain no matter the dose.)
What is potency in regards to dose-response?
The difference in concentration or dosage of different drugs required to produce similar effect.
Based on the graph, which medication is most potent and which is least?
Red is most potent, green is least.
What is ED50?
Dose required to produce a specific effect in 50% of patients.
What is LD50?
Lethal dose for 50% of the population.
Is drug-receptor binding reversible?
Yes, almost always.
What are the two types of drug responses (curves)?
Graded and quantal.
What are graded responses?
illustrate the degree of response to the dose. Dose modification will adjust the physiological response
(e.g., B/P, HR, Pain, etc.)
What are quantal responses?
Are "all or none" responses (e.g., Seizures, Pregnancy, Sleep, etc.)
What is drug selectivity?
Ratio of the dose or concentration producing the undesired effect to the dose producing the desired
effect.
What is the therapeutic index of range?
Difference between the dose that produces a desired effect and dose that produces undesired effects
(LD50/ED50).
, Regarding the therapeutic index of rang, what is MEC/MTC?
MEC (Minimum effective concentration): Level below which therapeutic effects will not occur.
MTC (Minimum toxic concentration): Level above which toxic effect begin
What are the three types of drugs that bind to receptors?
Agonists, antagonists, partial agonists.
What are agonists?
Binds to the receptor and cause a change in cellular activity. It has both affinity and efficacy. Can have
"spare" receptors.
AFFINITY + EFFICACY
What are antagonists?
Binds to the receptor, causes no change in cellular activity, and blocks the ability of endogenous
substances or other drugs to bind to the receptor. It lacks efficacy.
ONLY AFFINITY
What do antagonists do to the dose-response curve?
Shift it to be less potent.
What are examples of antagonists?
Beta-blockers (e.g., propranolol or atenolol) act as antagonists at the beta-adrenergic receptors
What happens if antagonists are abruptly DC'd?
Exaggerated response if they are abruptly discontinued due to an increased # of receptors.
What are partial agonists?
Binds to the receptor, causes a low level of change in cellular activity, but blocks endogenous substances
or other drugs from binding to the receptor.
True or false, Partial Agonists stimulate only some of the receptors (intrinsic activity)- thus they are
part agonist and part antagonist.
True.
What are examples of partial agonists?
