Document:
This letter concerns the marketing of the product Gastroade Xtra by your firm, Cox Veterinary Laboratory, Inc. The U.S. Food and Drug Administration (FDA) reviewed your website at the internet address coxvetlab.com, where you promote and sell this product, and obtained and tested samples of your product.
We have determined that Gastroade Xtra is intended for use in the mitigation, treatment, or prevention of disease in animals, which makes it a drug under section 201(g)(1)(B) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) [21 U.S.C. § 321(g)(1)(B)]. Under the FD&C Act, drugs intended for use in animals require an approved new animal drug application unless they are generally recognized as safe and effective. As discussed below, we have determined that your drug is not generally recognized as safe and effective, and is therefore unsafe under section 512(a)(1) of the FD&C Act [21 U.S.C. § 360b(a)], and adulterated under section 501(a)(5) of the FD&C Act [21 U.S.C. § 351(a)(5)], because you are marketing it without an approved new animal drug application. In addition, the drug is adulterated under section 501(c) of the FD&C Act [21 U.S.C. § 351(c)], as testing of the drug revealed that its strength differs from the strength stated on the label.
Because Gastroade Xtra is intended to mitigate, treat, or prevent disease in animals, it is a drug within the meaning of section 201(g)(1)(B) of the FD&C Act [21 U.S.C. § 321(g)(1)(B)]. Further, this product is a new animal drug, as defined by section 201(v) of the FD&C Act [21 U.S.C. § 321(v)], because it is not generally recognized among experts qualified by scientific training and experience to evaluate the safety and effectiveness of animal drugs, as safe and effective for use under the conditions prescribed, recommended, or suggested in the labeling.
To be legally marketed, a new animal drug must have an approved new animal drug application, conditionally approved new animal drug application, or index listing under sections 512, 571, and 572 of the FD&C Act [21 U.S.C. §§ 360b, 360ccc, and 360ccc-1]. Gastroade Xtra is not approved or Index listed by the FDA, and therefore the product is considered unsafe under section 512(a)(1) of the FD&C Act [21 U.S.C. § 360b(a)], and adulterated under section 501(a)(5) of the FD&C Act [21 U.S.C. § 351(a)(5)]. Introduction of an adulterated drug into interstate commerce is prohibited under section 301(a) of the FD&C Act [21 U.S.C. § 331(a)].
In addition, testing by FDA of samples of your product revealed that the amount of active ingredient (omeprazole) in your product did not correspond with the amount represented on the labeling. Specifically, your product was found to be sub-potent at 36.3% of the label claim for potency. Your product is therefore adulterated under section 501(c) of the FD&C Act [21 U.S.C. § 351(c)], in that its strength differs from that which it purports or is represented to possess.
