  Bioadhesives coatings increase the gastrointestinal retention time of orally-ingested medicaments. Certain bioadhesive coatings producing a fracture strength of at least 100 N/m 2 , as measured on rat intestine, when applied to at least one surface of a pharmaceutical dosage form for oral delivery of a drug, result in a gastrointestinal retention time of at least 4 hours in a fed beagle dog model, during which the drug is released from the dosage form. Multi-layer tablets, particularly those including hydrophobic excipients, are useful in administering hygroscopic and/or deliquescent drugs. In addition, varying the amount of drug in multi-layer tablets allows the release rate of the drug to be controlled.

  生物粘合剂涂层可以增加口服药物的胃肠道保留时间。当应用于至少一种药物剂型的表面以口服给药时，产生至少100 N/m²的断裂强度的某些生物粘合剂涂层（在大鼠肠道上测量）可导致在饲养的比格犬模型中至少保留4小时的胃肠道保留时间，在此期间药物从剂型中释放。多层片剂，特别是包括疏水助剂的多层片剂，可用于给予吸湿性和/或易溶性药物。此外，改变多层片剂中药物的量可以控制药物的释放速率。
