Sustained-release compositions comprising a macrolide compound, a surfactant, a co-solvent, and a solvent. The sustained-release compositions of this invention may be parenterally administered to animals, and are useful for preventing or treating helminth, acarid or arthropod endo- or ectoparasitic infection or infestation in warm-blooded animals for prolonged periods of time.

Sustained-release compositions for parenteral administration

The invention relates to certain stable microsphere compositions containing a fat, a wax or a mixture thereof; an active ingredient selected from LL-F28249&agr;-&lgr; compounds, 23-oxo or 23-imino derivatives of LL-F28249&agr;-&lgr; compounds, milbemycin compounds and avermectin compounds; an antioxidant and, optionally, an oil, a semi-soft fat, a fatty acid derivative or mixture thereof. The invention also relates to a method for introducing and maintaining levels of the active compound in the blood of warm-blooded animals for extended periods of time and for the prevention or treatment of infections and infestations caused by helminths, nematodes, acarids and endo- and ectoparasitic arthropods in warm-blooded animals by the parenteral administration of compositions of the invention.

Stable compositions for parenteral administration and their use

The invention relates to implants for the parenteral administration of an essentially uniform and continuous amount of a biologically active protein, peptide or polypeptide over an extended period of time which comprises a compacted, indented and partially coated composition containing from one to three layers of a homogeneous core mixture comprising about 20% to about 80% of a biologically active protein, a peptide or a polypeptide; about 10% to about 75% of a fat, a wax or a mixture thereof; 0% to about 25% of a buffer, a salt, a sugar or a mixture thereof; 0% to about 15% of a filler, on a weight basis of the total weight of the core mixture. The partial coating of a semipermeable material comprises about 5% to about 50%, on a weight basis of the total weight of the implant. The invention also relates to methods for increasing and maintaining elevated blood levels of biologically active proteins, peptides and polypeptides in animals by the administration of said implants.

Implant compositions containing a biologically active protein, peptide

A therapeutic composition which contains a potentiating or safening amount of an aqueous surfactant in combination with a bactericidal agent and/or a biological response modifier is described herein. The disclosure further describes an improved method for treating mastitis by administering the composition to an afflicted mammal. Additionally, the disclosure describes a method for screening suitable formulations for treating infectious diseases.

Compositions for the treatment of mammalian diseases

The invention relates to certain stable microsphere compositions suitable for parenteral administration containing a fat or wax or mixture thereof; a biologically active protein, peptide or polypeptide; and an oil, semi-soft fat, fatty acid derivative or mixture thereof. The invention also relates to a method of making the microsphere compositions.

Stable compositions for parenteral administration and method of making

Veterinary delayed release dosage forms which remain in the rumeno-reticular sac of an animal over an extended period of time and in which the therapeutically active substance has a predictable and delayed release pattern. The compositions comprise a dense filler, a disintegrant and a therapeutically active substance. The dosage form has a hydrophobic polymer or co-polymer coating and can deliver a plurality of doses of a medicament intermittently at a preset time interval in the rumen.

Intermittent release dosage form

Veterinary delayed release dosage forms which remain in the rumeno-reticular sac of an animal over an extended period of time and in which the therapeutically active substance has a predictable and delayed release pattern. The compositions comprise a dense filler, a disintegrant and a therapeutically active substance. The dosage form a hydrophobic polymer or co-polymer coating and can deliver a plurality of doses of a medicant intermittently at a present time interval in the rumen.

The invention is a microsphere composition of fat or wax or mixture thereof and a biologically active protein, peptide or polypeptide suitable for parenteral administration. The invention is also a slow release composition of fat or wax or mixture thereof and a biologically active protein, peptide or polypeptide suitable for parenteral administration. The invention also relates to methods for increasing and maintaining increased levels of growth hormone in the blood of treated animals for extended periods of time, increasing weight gains in animals, and increasing milk production of lactating animals by the administration of compositions of the invention.
