(SELENIUM, VITAMIN E)

Injection

FOR VETERINARY USE ONLY

E-SE Caution

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Description

E-SE Injection is an emulsion of selenium-tocopherol for the prevention and treatment of myositis (Selenium-Tocopherol Deficiency) syndrome in horses. Each mL contains: 5.48 mg sodium selenite (equivalent to 2.5 mg selenium), 50 mg (68 IU) vitamin E (as d-alpha tocopheryl acetate), 250 mg polyoxyethylated vegetable oil, 2% benzyl alcohol (preservative), water for injection q.s. Sodium hydroxide and/or hydrochloric acid may be added to adjust pH.

Pharmacology

It has been demonstrated that selenium and tocopherol exert physiological effects and that these effects are intertwined with sulfur metabolism. Additionally, tocopherol appears to have a significant role in the oxidation process, thus suggesting an interrelationship between selenium and tocopherol in overcoming sulfur-induced depletion and restoring normal metabolism. Although oral ingestion of adequate amounts of selenium and tocopherol would seemingly restore normal metabolism, it is apparent that the presence of sulfur and perhaps other factors interfere during the digestive process with proper utilization of selenium and tocopherol. When selenium and tocopherol are injected, they bypass the digestive process and exert their full metabolic effects promptly on cell metabolism. Anti-inflammatory action has been demonstrated by selenium-tocopherol in the Selye Pouch Technique and experimentally induced polyarthritis study in rats.

E-SE Indications

E-SE Injection is recommended for the control of the following clinical signs when associated with myositis (Selenium-Tocopherol Deficiency) syndrome: rapid respiration, profuse sweating, muscle spasms and stiffness, elevated SGOT.

E-SE Caution

Intravenous administration, if elected, should be by slow injection.

Emulsions injected intramuscularly into the horse may produce transitory local muscle soreness and can be prevented to some degree by injecting deeply (2 to 2 1/2 inches), in divided doses, in two or more sites. Do not continue therapy in horses demonstrating such sensitivity.

Selenium is toxic if administered in excess. A fixed dose schedule is therefore important (read the package insert for each selenium-tocopherol product carefully before using).

WARNINGS Anaphylactoid reactions, some of which have been fatal, have been reported in horses administered E-SE Injection. Signs include excitement, sweating, trembling, ataxia, respiratory distress, and cardiac dysfunction. These reactions have been reported in association with both intravenous and intramuscular injections. It is presently unknown whether the mode of application affects the frequency of such reactions. However, reactions associated with intramuscular injections have been reported to manifest more slowly and hence may give more time to institute treatment for anaphylaxis, such as epinephrine and/or corticosteroid injection.

Medications which have been reported to cause major adverse reactions in horses should be avoided when E-SE is administered, unless the condition of the animal requires such use.

Not to be used in horses intended for food.

DOSAGE AND ADMINISTRATION Administration: Administer by slow intravenous injection (see WARNINGS) or deep intramuscular injections, in divided doses in two or more sites in the gluteal or cervical muscles. Dosage: 1 mL per 100 pounds of body weight. May be repeated at 5-10 day intervals.

PRECAUTIONS Selenium-Tocopherol Deficiency (STD) syndrome produces a variety and complexity of symptoms often interfering with a proper diagnosis. Even in selenium deficient areas there are other disease conditions which produce similar clinical signs. It is imperative that all these conditions be carefully considered prior to the treatment of STD syndrome. Serum selenium levels, elevated SGOT, and creatine serum levels may serve as aids in arriving at a diagnosis of STD, when associated with other indices.

Important Use only the selenium-tocopherol product recommended for each species. Each formulation is designed for the species indicated to produce the maximum efficacy and safety.
