The present invention addresses the problem of providing lipid nanoparticles which function as gene transfer carriers capable of selective transfer to the liver or spleen. Lipid nanoparticles which contain a pH-sensitive cationic lipid represented by formula (I) [a represents an integer of 3-5; b represents 0 or 1; Rand Reach independently represent a group represented by general formula (A) (Rand Reach independently represent a linear or branched Calkyl group; c represents 0 or 1; v represents an integer of 4-12); and X represents a group represented by general formula (B)(d represents an integer of 0-3; and Rand Reach independently represent a Calkyl group or Calkenyl group, while Rand Rmay form a 5- to 7-membered non-aromatic heterocycle) or represents a 5- to 7-membered non-aromatic heterocyclic group]. (I) (R)(R)C(OH)—(CH)a-(O—CO)b-X. (A): (R)(R)—CH—(CO—O)c-(CH)v-. (B):—(CH)d-N(R)(R).(R)(R)C(OH)—(CH)—(O—CO)-X  (I)(R)(R)—CH—(CO—O)—(CH)-  (A)—(CH)-N(R)(R)  (B)

The present invention aims to provide a method and an apparatus for producing a lyophilized body, each of which can achieve energy saving, low cost, and a reduction in processing time and can provide a lyophilized body less damaged by a freezing process and a drying process. The present invention relates to a method for lyophilizing a substance using an electromagnetic wave, and the lyophilization method includes freezing the substance under irradiation of at least an electromagnetic wave and reduced-pressure drying the frozen substance under irradiation of at least an electromagnetic wave.

Method for manufacturing freeze-dried body and manufacturing device for same

The problem of the present invention is to provide a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of a drug, particularly, a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of an acidic drug. A composition for enhancing transdermal absorption of a drug, comprising an unsaturated higher alcohol having 12-20 carbon atoms and a polyvalent alcohol having 3-8 carbon atoms. A composition for enhancing transdermal absorption of a drug, comprising an unsaturated higher alcohol having 12-20 carbon atoms, a polyvalent alcohol having 3-8 carbon atoms and an organic amine having 2-9 carbon atoms.
