摘要 |
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.
