injection) is a sterile, ready-to-use solution refrigeration; however, it is recommended for the administration of the broad-spectrum that it be stored at room temperature, 15°- antibiotic oxytetracycline (Terramycin) by 30°C (59°-86°F). The antibiotic activity of injection. Terramycin, discovered by Pfizer scientists, is an antimicrobial agent that is diminished in the presence of body fluids, effective in the treatment of a wide range of disease caused by susceptible gram-positive and gram-negative bacteria.

Exceeding the highest recommended dosage level of drug per pound of body weight per day,
administering more than the recommended number of treatments, and/or exceeding 10 ml
intramuscularly per injection site in adult beef cattle and nonlactating dairy cattle, and 5 ml
intramuscularly per injection site in adult swine, may result in antibiotic residues beyond the
withdrawal period.

Reactions of an allergic or anaphylactic nature, sometimes fatal, have been known to occur in hypersensitive animals following the injection of oxytetracycline. Such adverse reactions can be characterized by signs such as restlessness, erection of hair, muscle trembling; swelling of eyelids, ears, muzzle, anus and vulva ( or scrotum and sheath in males); labored breathing, defecation and urination, glassy-eyed appearance, eruption of skin plaques, frothing from the mouth, and prostration. Pregnant animals that recover may subsequently abort. At the first sign of any adverse reaction, discontinue use of this product and administer epinephrine at the recommended dosage levels. Call a veterinarian immediately.
Shock may be observed following intravenous administration, especially where highly concentrated materials are involved. To minimize this occurrence, it is recommended that LIQUAMYCIN® LA-200 ® be administered slowly by this route.
Shortly after injection, treated animals may have transient hemoglobinuria resulting in darkened urine.
As with all antibiotic preparations, use of this drug may result in overgrowth of non-susceptible organisms, including fungi. A lack or response by the treated animal, or the development of new signs, may suggest that an overgrowth of non-susceptible organisms has occurred. If any of these conditions occur, consult your veterinarian.
Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving LIQUAMYCIN® LA-200 ® in conjunction with penicillin.
STORAGE: Store at room temperature, 15°-30°C (59°-86°F). Keep from freezing.

Lasix ® (furosemide) is a chemically distinct diuretic and saluretic pharmacodynamicallycharacterized by the following: 1) A high degree of efficacy, low-inherent toxicity and a high therapeutic index.
2) A rapid onset of action and of comparatively short duration. 1,2 3) A pharmacological action in the functional area of the nephron, i.e., proximal and distal tubules and the ascending limb of the loop of Henele, 2, 3, 4 4) A dose-response relationship and a ratio of minimum to maximum effective dose Generic name: Furosemide (except in United Kingdom-frusemide). Chemical name: 4-chloro-N-furfuryl-5-sulfamoylanthranilic acid.
5) If may be administered orally or parenterally. It is readily absorbed from the intestinal tract and well tolerated. The intravenous route produces the most rapid diuretic response.

Acepromazine Maleate, a potent neuroleptic agent with a low order of toxicity, is of particular value In the tranquilization of dogs, cats, and horses. Its rapid action and lack of hypnotic effect are added advantages.
According to Baker,' the scope of possible applications for this compound in veterinary practice is only limited by the imagination of the practitioner.
Acepromazine (10.(3.(dimethylamino) propyl) phenothiazin-2-yl-methyl ketonel Maleate has the ACTIONS:
PromAce (Acepromazine Maleate) has a
depressant effect on the central nervoussystem and therefore causes sedation, muscular PromAce Injectable can be used as an aid in relaxation and a reduction in spontaneous activity It acts rapidly, exerting a prompt and transportation. Particularly useful whenused in conjunction with local anesthesia for INDICATIONS:

PromAce Injectable and Tablets can be used as an aid in controlling intractable animals during examination, treatment. grooming, x.ray, and minor surgical procedures; to alleviate itching as a result of skin irritation; as an antie-metic to control vomiting associated with motion sickness. PromAce Injectable is particularly useful as a preanesthetic agent (1) to enhance and prolong the effects of barbiturates, thus reducing the requirements for general anesthesia; (2) as an adjunct to surgery under Local anesthesia.
