摘要:
The present invention relates to an anti-adhesion polymer composition capable of supporting growth factor, which effectively exhibits anti-adhesion function and, at the same time, has an excellent adhesive property so as to be able to easily and continuously adhere to a wound site, has antibacterial and hemostatic properties, and is composed of an injectable formulation suitable for use in minimally invasive surgery, laparoscopic surgery or the like. The anti-adhesion polymer composition capable of supporting growth factor comprises: 24-50 wt % of a polyethyleneglycol-polypropyleneglycol-polyethyleneglycol (PEG-PPG-PEG) block copolymer having a polyethyleneglycol (PEG) content of 65-85 wt % and a molecular weight of 6,000-20,000 Da; 0.03-5 wt % of gelatin; 0.03-5 wt % of chitosan; and distilled water.

摘要:
The present invention relates to a carrier for growth factor related to regeneration of bone tissues that is capable of arbitrarily controlling the delivery rate of growth factors related to bone regeneration and thus especially applicable to a bone void filler in the fields of the dental or orthopedic applications.The carrier for controlling the delivery rate of the growth factor in the present invention is composed of a hyaluronic acid hydrogel having a distribution of interconnected pores and a calcium phosphate microsphere being distributed in the pores of the hyaluronic acid hydrogel. The calcium phosphate microsphere having a porosity suitable for delivery of the growth factor is positioned into the pores of the cross-linked hyaluronic acid hydrogel to complete the carrier.

Disclosed is a transdermal preparation containing a hydrophobic drug. As a method of continuing the high drug permeation, it is used an unique hydrophilic polymer system in which the drug can be contained in a high concentration under no water environment, a solubility of the hydrophobic drug is decreased as the water is introduced to the patch from the skin, so that the drug is maintained at the saturation concentration even though the drug content is decreased as the drug is permeated to the skin. During the application of the transdermal preparation to the skin, it is possible to continuously permeate the high amount of drug, to maintain the sufficient adhesion during the use and to minimize the skin side effect, because the hydrophilic polymer absorbs the water from the skin. The hydrophilic polymer system can serve the function thereof through the hydrophobic adhesive layer capable of preventing the water quickly absorbed from the skin from being evaporated to the outside of the patch.

The present, invention relates to a transdermal absorption preparation. The transdermal absorption preparation of the present invention comprises a drug-containing adhesive layer, a drug-protective layer and a release layer, wherein the drug-containing adhesive layer contains ropinirole or a salt thereof, rubber, an adhesion-imparting resin, an antioxidant, and a transdermal absorption promoter. Also, the present invention provides a transdermal absorption preparation comprising a drug-containing adhesive layer, a drug-protective layer, and a release layer, wherein the drug-containing adhesive layer contains ropinirole or a salt thereof, acrylic rubber, an anti-crystallisation agent, and a transdermal absorption promoter. When the transdermal absorption preparation of the present invention is used for the treatment of Parkinson's disease or restless leg syndrome, no side effect due to an increase in the initial drug concentration in blood occurs and the skin penetration effect of the drug is excellent.
