CORRECT & VERIFIED SOLUTIONS.
What is extra-label drug use (ELDU)? - ANSWER ☑☑ELDU describes the use of an
approved drug in a manner that is not in accordance with the approved labeling,
yet meets the conditions set forth by the Animal Medicinal Drug Use Clarification
Act of 1994 (AMDUCA) and U.S. Food and Drug Administration (FDA) regulations.
What deviations from FDA-approved labeling make it ELDU? - ANSWER ☑☑use in
another species use for a different indication use at a different dose or frequency
use via a different route of administration.
What is the purpose of the Animal Medicinal Drug Use Clarification Act
(AMDUCA)? - ANSWER ☑☑The Animal Medicinal Drug Use Clarification Act of
1994 (AMDUCA) made ELDU an FDA-regulated veterinary medical activity,
allowing veterinarians to prescribe extra-label uses of approved animal and
human drugs when the health of an animal is threatened, or when suffering or
death may result from failure to treat animals.
Prior to the passage of the AMDUCA, ELDU of animal drugs was illegal. AMDUCA
amended the Federal Food, Drug, and Cosmetic Act to legalize ELDU under a valid
VCPR as well as certain other conditions describing requirements for use, record
requirements, and label requirements according to FDA regulations.
,Isn't ELDU only for food-producing animals? If not, to which species do ELDU
regulations apply? - ANSWER ☑☑ELDU regulations apply to all animal species,
not only food-producing animals.
Who regulates ELDU and enforces the regulations? - ANSWER ☑☑The FDA Center
for Veterinary Medicine regulates ELDU and enforces the regulations. In cases of
AMDUCA violations, FDA regulatory actions may include warning letters, seizure of
product, misdemeanor fines, injunction or criminal prosecution.
Is "off-label" use the same as ELDU? - ANSWER ☑☑"Off-label" is a term
commonly used in foreign countries, and by physicians in the United States. It is
also sometimes used in veterinary medicine in the U.S., but the term has no legal
or regulatory definition. In the United States, extralabel drug use is the
appropriate term.
How do I know what qualifies as ELDU? - ANSWER ☑☑Specific criteria must be
followed:
-A valid VCPR is a prerequisite for all ELDU;
-Only a veterinarian can determine that ELDU is needed and can administer,
prescribe or dispense a medication extralabelly. The veterinarian must direct or
supervise ELDU in an animal;
-ELDU rules only apply to FDA-approved animal and human drugs;
-ELDU is intended for prevention, treatment, and control purposes only when an
animal's health is threatened.
-ELDU is not permitted if it results in an illegal food residue, or any residue which
may present a risk to public health;
,-A veterinarian must not pursue use of certain FDA-prohibited drugs in
foodproducing animals
ELDU of an FDA approved drug may be used if: - ANSWER ☑☑-There is no
approved animal drug that is labeled for such use, or that contains the same
active ingredient in the required dosage form and concentration.
-Alternatively, an approved animal drug for that species and condition exists, but a
veterinarian finds, within the context of a VCPR, that the approved drug is
clinically ineffective for its labeled use.
How did ELDU regulation come about and why is it necessary in veterinary
medicine? - ANSWER ☑☑Prior to enactment of the AMDUCA, the Federal Food,
Drug, and Cosmetic Act had provided that a new animal drug was deemed unsafe
unless it was subject to the FDA's stringent approval process - for exactly what was
on the label - specific species, disease indication, dose, duration, frequency, and
route of administration.
Created a relative disincentive for companies to put resources toward creating
new veterinary drugs. Making it harder to treat.
Minor species have few to no drugs approved for various indications.
The following additional conditions must be met for ELDU in food-producing
animals: - ANSWER ☑☑-Such use must be accomplished in accordance with an
appropriate medical rationale; and
, -If scientific information on the human food safety aspect of the use of the drug in
food producing animals is not available, the veterinarian must take appropriate
measures to assure that the animal and its food products will not enter the human
food supply.
An approved animal drug must be considered for the particular use before a drug
labeled for humans is considered. The prescribed or dispensed extralabel drug
(prescription legend or over-the-counter) must bear labeling information which is
adequate to assure the safe and proper use of the product.
What drugs qualify for ELDU? - ANSWER ☑☑Any drug approved by the FDA
qualifies for ELDU in a non-food-producing animal given that a valid VCPR exists
and FDA-delineated criteria are met. For food-producing animals, the extralabel
use of certain drugs is prohibited.
What does AMDUCA mean to the everyday veterinary practice? - ANSWER
☑☑Keep in mind that AMDUCA does not give veterinarians "carte blanche" for
extralabel use of medications. There are certain guidelines to follow. To the
everyday veterinary practice, this means that the veterinarian should do the
following when considering ELDU:
-Make a careful diagnosis and evaluation of the conditions for which the drug is to
be used;
-First make certain there is no approved animal drug that is labeled for such use in
that species, or that contains the same active ingredient in the required dosage
form and concentration;Alternatively, if an approved animal drug exists but a
veterinarian finds, within the context of a veterinarian-client-patient relationship,
that the approved drug is clinically ineffective for its intended use, extralabel use
of an alternative medication is permissible.
-Assure that the identity of the treated animal(s) is carefully maintained;
