The invention provides pharmaceutical compositions comprising macromolecular gastrointestinal enzyme-labile opioid prodrugs, co-formulated with small-molecule and/or macromolecular gastrointestinal enzyme inhibitors. The macromolecular constructs are minimally absorbed from the GI tract, and can produce non-linear pharmacokinetic profiles of the delivered opioid agonist following oral ingestion. An optional macromolecular opioid antagonist may also be present in compositions of the invention to discourage tampering by potential abusers.
本发明提供了由大分子胃肠道酶抑制阿片类原药与小分子和/或大分子胃肠道酶抑制剂共同配制而成的药物组合物。大分子构建物从胃肠道的吸收率极低,口服后可产生所输送阿片类激动剂的非线性药代动力学特征。本发明的组合物中还可加入一种可选的大分子阿片拮抗剂,以防止潜在的滥用者篡改。
