Tylvalosin Tartrate Chemical Nomenclature And Structure

(4R,5S,6S,7R,9R,11E,13E,15R,16R)-15-{[(6-deoxy-2,3-di-O-methyl-β-D-allopyranosyl)oxy]methyl}-6-({3,6-dideoxy-4-O-[2,6-dideoxy-3-C-methyl-4-O-(3-methylbutanoyl)-α-L-ribo-hexopyranosyl]-3-(dimethylamino)-β-D-glucopyranosyl}oxy)-16-ethyl-5,9,13-trimethyl-2,10-dioxo-7-(2-oxoethyl)oxacyclohexadeca-11,13-dien-4-yl acetate (2R,3R)-2,3-dihydroxybutanedioate.

Antibiotic Classification

Tylvalosin, the active ingredient in Aivlosin® Water Soluble Granules, is a macrolide antibiotic.


Control of porcine proliferative enteropathy (PPE) associated with Lawsonia intracellularis infection in groups of swine in buildings experiencing an outbreak of PPE.

Control Of Porcine Proliferative Enteropathy

Prepare drinking water medicated with 50 parts per million Tylvalosin as shown in the following table.Aivlosin® Water Soluble Granules sachet size40 grams160 grams400 gramsTylvalosin content of sachet (grams)25100250Recommended volume of stock solution (US gallons)1410Volume of drinking water (US gallons)1325281320Final tylvalosin inclusion rate in drinking water50 parts per million (ppm)Administer continuously in drinking water for five (5) consecutive days.Keep water supply equipment clean and in good operating condition. Clean water medication equipment before and after each use. Do not mix or administer Tylvalosin medicated water using equipment made of galvanized metal. Galvanized metal adversely affects the stability of Tylvalosin in water and may reduce the effectiveness of the product. Prepare a fresh batch of medicated stock solution or medicated drinking water daily.

Mixing Directions

Aivlosin® Water Soluble Granules may be mixed directly into the drinking water system or first mixed as a stock solution in a smaller amount of water, which is then added to the drinking water system, for example, using an automatic water proportioner.

Direct Mixing

When mixing the product directly into the drinking water system, the contents of the sachet should be sprinkled onto the surface of the water and mixed slowly and thoroughly for at least 3 minutes. Prepare a fresh batch of medicated drinking water daily.

Stock Solution

When preparing a stock solution, the recommended concentration is one 40-gram sachet per US gallon, or one 160-g sachet per four (4) US gallons or one 400-gram sachet per 10 US gallons. Sprinkle sachet contents onto the surface of the water of the stock solution and mix slowly and thoroughly for at least 10 minutes. Use the stock solution for dilution into the drinking water system as soon as it is prepared. Add one (1) fluid ounce of this stock solution per 131 fluid ounces (1 US gallon, 3 fluid ounces) of drinking water to provide a final concentration of 50 ppm. If using an automatic water proportioner, set the flow rate to add stock solution at a rate of 1 fluid ounce per 131 fluid ounces of drinking water (1:131). Prepare a fresh batch of medicated stock solution daily.



Withdrawal Period

When used in accordance with label directions, no withdrawal period is required before slaughter for human consumption.

Antibacterial Warnings

Use of antibacterial drugs in the absence of a susceptible bacterial infection is unlikely to provide benefit to treated animals and may increase the development of drug-resistant pathogenic bacteria.

User Safety Warnings

May cause skin irritation.Tylvalosin Tartrate has been shown to cause hypersensitivity reactions in laboratory animals. People with known hypersensitivity to Tylvalosin Tartrate should avoid contact with this product. In case of accidental ingestion, seek medical advice. When handling Aivlosin® Water Soluble Granules and preparing medicated drinking water, avoid direct contact with the eyes and skin. Wear a dust mask, coveralls and impervious gloves when mixing and handling this product. Eye protection is recommended. In case of accidental eye exposure, wash eyes immediately with water. If irritation persists, seek medical attention. Avoid eating, chewing gum and smoking during handling.Wash contaminated skin.The Material Safety Data Sheet contains more detailed occupational safety information.To report adverse effects in users, to obtain more information or obtain a Material Safety Data Sheet, call the ASPCA Animal Product Safety Service at 1-800-345-4735.


Not for use in lactating or pregnant females, or males and females intended for breeding. The effects of Tylvalosin on swine reproductive performance, pregnancy and lactation have not been determined. The safety and efficacy of this formulation in species other than swine have not been determined.

Adverse Reactions In Animals

No adverse reactions related to the drug were observed during clinical or target animal safety trials. To report suspected adverse reactions in animals, contact the ASPCA Animal Product Safety Service at 1-800-345-4735 or the FDA at 1-888-FDA-VETS.

Clinical Pharmacology

Tylvalosin is a 16-membered semi-synthetic macrolide antibiotic. Macrolides are generally considered to be bacteriostatic agents that exert their antibiotic effect by reversibly binding to the 23S rRNA of the 50S ribosomal subunit, thereby inhibiting bacterial protein synthesis. The spectrum of activity of most available macrolides used in veterinary medicine is primarily against Gram-positive bacteria and Mycoplasmas, with some activity against Gram-negative fastidious bacteria. These compounds have no activity against the naturally resistant Enterobacteriaceae including Escherichia coli and Salmonella spp. Typically, macrolides achieve higher concentrations in tissues than in plasma.

Control Of Porcine Proliferative Enteropathy (Ppe)

A multi-location challenge model study was conducted to confirm the effectiveness of AIVLOSIN® Water Soluble Granules for the control of PPE associated with Lawsonia intracellularis. Pigs were challenged by intragastric gavage with a mucosal homogenate containing a North American isolate of Lawsonia intracellularis isolated in 2005 that induces representative disease in challenged pigs. When at least 15% of the study pigs were showing signs of infection based on abnormal fecal scores, pigs were provided water containing tylvalosin at an inclusion rate of 50 ppm for five consecutive days, or were provided non-medicated water.Effectiveness was evaluated using clinical scores (pig demeanor score, abdominal appearance score, and fecal score) and clinically-validated gross PPE lesion scores. A conclusion of the effectiveness of 50 ppm tylvalosin for the control of PPE was determined based on a statistically significant (p = 0.0103) improvement in the clinically-validated gross PPE lesion scores in the 50 ppm tylvalosin-treated group compared to the non-medicated group.

Margin Of Safety

Aivlosin® Water Soluble Granules given orally in drinking water at 0, 50, 150 and 250 ppm tylvalosin (0, 1×, 3× and 5× the labeled dose, respectively) to 8 healthy pigs per treatment group over 15 days (3× the labeled duration) did not result in drug-induced clinical signs, gross pathologic lesions, histopathologic lesions or clinically-relevant clinical pathology abnormalities.


Store in a cool dry place at or below 25°C (77°F).

How Supplied

Aivlosin® Water Soluble Granules is packaged in 40-, 160- and 400-gram sachets supplied in boxes holding 20, 10 and 5 sachets respectively.
