The present invention relates to compositions and methods which enhance the local and systemic uptake and delivery of oligonucleotides and nucleic acids via non-parenteral routes of administration. Pharmaceutical compositions comprising oligonucleotides disclosed herein include, for systemic delivery, emulsion and microemulsion formulations for a variety of applications and oral dosage formulations. It has also suprisingly been discovered that oligonucleotides may be locally delivered to colonic sites be rectal enemas and suppositories in simple solutions, e.g., neat or in saline. Such pharmaceutical compositions of olignonucleotides may further include one or more penetration enhancers for the transport of oligonucleotides and other nucleic acids across mucosal membranes. The compositions and methods of the invention are utilized to effect the oral, buccal, rectal or vaginal administration of an antisense oligonucleotide to an animal in order to modulate the expression of a gene in the animal for investigative, therapeutic, palliative or prophylactic purposes.
本发明涉及通过非肠道给药途径提高寡核苷酸和核酸的局部和全身摄取和递送的组合物和方法。本发明公开的包含寡核苷酸的药物组合物包括用于全身给药的乳剂和微乳剂制剂以及口服制剂。人们还意外地发现,寡核苷酸可以通过直肠灌肠剂和栓剂以简单的溶液(如纯溶液或生理盐
水)局部输送到结肠部位。这种寡核苷酸药物组合物可进一步包括一种或多种渗透
促进剂,以促进寡核苷酸和其他核酸在粘膜上的转运。本发明的组合物和方法可用于对动物口服、口腔、直肠或阴道给药反义寡核苷酸,以调节动物体内
基因的表达,达到研究、治疗、缓解或预防的目的。
