Generic Name: Ketamine Hydrochloride Injection, USP
Dosage Form: Solution
How Supplied: 10 mL multiple dose bottles
How Dispensed: Rx
Amount of Active Ingredients:
Each mL contains ketamine
hydrochloride equivalent to 100 mg ketamine base
Route of Administration: Intramuscular injection
Species: Cats and subhuman primates
Labeled Dosage:
- Cats:
A dose of 11 mg/kg (5mg/lb) is
recommended to produce restraint. Dosages from 22 to 33 mg/kg (10 to 15
mg/lb) produce anesthesia that is suitable for diagnostic or minor
surgical procedures that do not require skeletal muscle relaxation.
- Subhuman primates:
The recommended restraint dosages for the following species
are: Cercocebus torquatus (white-collared mangabey), Papio
cynocephalus (yellow baboon), Pan troglodytes verus (chimpanzee),
Papio anubis (olive baboon), Pongo pygmaeus (orangutan),
Macaca nemestrina (pig-tailed macaque), 5 to 7.5 mg/kg; Presbytis
entellus (entellus langur), 3 to 5 mg/kg; Gorilla gorilla gorilla
(gorilla), 7 to 10 mg/kg; Aotus trivirgatus (night monkey), 10 to 12
mg/kg; Macaca mulatta (rhesus monkey), 5 to 10 mg/kg; Cebus capucinus
(white-throated capuchin), 13 to 15 mg/kg; Macaca fascicularis
(crab-eating macaque), Macaca radiata (bonnet macaque), and
Saimiri sciureus (squirrel monkey) 12 to 15 mg/kg.
Indications for Use:
Ketaject® (ketamine hydrochloride injection. USP)
may be used in cats for restraint or as the sole anesthetic agent
for diagnostic or minor brief, surgical procedures that do not require
skeletal muscle relaxation. It may be used in subhuman primates for
restraint.
Pioneer Product :
Vetalar® /Ketaset® (ketamine hydrochloride
injection, USP.
100 mg/mL), NADA 045-290 by Fort Dodge Laboratories, Inc.
Date of Approval: June 30, 1994
2. TARGET ANIMAL SAFETY AND DRUG EFFECTIVENESS:
Under the provisions of the Federal Food, Drug, and Cosmetic Act, as
amended by the Generic Animal Drug and Patent Term Restoration Act (53 FR
50460, December 15, 1988; first GADPTRA Policy Letter) an Abbreviated New
Animal Drug Application (ANADA) may be submitted for a generic version of an
approved new animal drug (pioneer product). For certain dosage forms, the
Agency grants a waiver from conducting an in vivo bioequivalence study
(55 FR 24645, June 18, 1990; fifth GADPTRA Policy Letter). In lieu of
bioequivalence testing, the safety and efficacy of the generic product are
based on the demonstrated chemical equivalence to the pioneer product.
Based on the formulation characteristics of the generic product, Phoenix
Pharmaceutical, Inc. was granted a waiver July 19, 1990 (see Section 4)
from conducting an in vivo bioequivalence study with Ketaject®. The
generic and pioneer products are solutions with the same inactive ingredients
and the same concentrations of the active ingredient.
3. HUMAN SAFETY:
Human Safety Relative to Food Consumption:
Regarding consumption of drug residues in food, human safety data were not
required for approval of this ANADA. This drug is labeled for use in cats and
subhuman primates not intended for food.
Human Safety Relative to Possession, Handling and Administration:
Labeling contains adequate caution/warning statements.

Dear Dr. Schafer,
We refer to your submission dated April 9, 1990, requesting an Investigational
Exemption for a generic copy of Ketaset (ketamine hydrochloride injection) for
intramuscular use in cats as an anesthetic and restraining agent and in subhuman primates as a reastraining
agent. The Submission also contained a request for a waiver of in vivo bioequivalence
testing required for an Abbreviated New Animal Drug Application (ANADA).
Based on the information you provided, your proposed product is a solution containing the
same active and inactive ingredients as the pioneer product.
It is inteded solely for intramuscular injection. It is, therefore, eligible for waiver from
in vivo bioequivalence testing under our current policy.
Your request for a waiver is granted on the condition that the full
information presented in your ANADA continues to show that your proposed
generic product is chemically equivalent to the pioneer product. If it is not shown
to be chemically equivalent, in vivo bioequivalence testing
could be required.
Granting of this waiver does not assure approval of your ANADA. All
necessary requirements must be fulfilled, including certification that
your product or its proposed uses do not violate or infringe upon any
patent or exclusivity for the pioneer product or its uses.
For administrative purposes, we have assigned you Investigational New Animal Drug (INAD)
number 6752 for the above referenced use of ketamine
hydrochloride. In submitting your ANADA, please refer to this number and
include a copy of this correspondence in your original submission. All
future correspondence pertaining to his drug should be sent to the following:

5. AGENCY CONCLUSIONS:
This is an Abbreviated New Animal Drug Application (ANADA) filed under Section
512(b)(2) of the Federal, Food, Drug and Cosmetic (FFD&C) Act.
Safety and effectiveness for this generic animal drug, Ketaject® (ketamine
hydrochloride, USP, 100 mg/mL), were established by demonstration of chemical
equivalence to the pioneer product, Fort Dodge Laboratories'
Vetalar®/Ketaset® (ketamine hydrochloride, USP,100 mg/mL. NADA 045-290).
This generic product and the pioneer product have identical labeling
indications for use. The route and method of administration of the two drugs
are identical. Both drugs are administered by intramuscular injection. The
generic and pioneer products are both solutions that contain the same active
and inactive ingredients in the same concentrations. Both products have the
same pH. Therefore, in compliance with FDA policy promulgated to implement
Section 512(b)(2) of the FFD&C Act, no additional safety, efficacy, or
in vivo bioequivalency studies were necessary or required.
This ANADA satisfies the requirements of section 512 of the Act and
demonstrates that Ketaject® is safe and effective for its labeled indications
when used under its proposed conditions of use.
