摘要:
A medical lubricant suitable for injection into the blood stream of a patient. The lubricant is suitable for use with rotating equipment such as atherectomy drive shafts moving within sheaths and over guide wires and other minimally invasive medical devices introduced into a patient through a catheter like instrument. The lubricant is an oil-in-water emulsion including a surfactant, a co-surfactant, and a pH buffer. The lubricant can further include a cryogenic agent and a pH adjusting agent. One lubricant includes olive oil as an emulsified oil, egg yolk phospholipid as a surfactant, sodium deoxycholate as a co-surfactant, glycerin as a cryogenic agent, L-histidine as a pH buffer, and is pH adjusted using sodium hydroxide. The lubricant can also include a therapeutic agent. The lubricant can withstand freeze/thaw cycles as well as saline dilution, heating, and shear stress without significant creaming, separation, or unacceptable increases in oil droplet size. Compared to saline, the lubricant provides significantly increased lubrication efficiency for rapidly moving parts.
摘要:
A flexible transparent container for improved storage of oxygen sensitive parenterally administerable agents comprising an inner, primary container enclosed in a substantially oxygen impermeable outer envelope. The inner container is made of a polypropylene containing flexible polymeric material compatible with lipophilic agents capable of forming both permanent and peelable seals, while the envelope is made of a substantially water impermeable flexible multilayered polymeric material comprising a first outer substantially water impermeable polymeric film with oxygen barrier forming capacity, assembled with a second, inner polymeric film with a supplementary oxygen barrier forming capacity. The container essentially maintains its characteristics after being subjected to sterilization by steam or radiation.

摘要:
The present invention relates to preparations to be used in therapy or nutrition containing stabilized or solubilized forms of amino acids otherwise unstable in solution or poorly soluble in aqueous fluids. The sensitive amino acids are included in the said preparations as glyceryl esters of compounds chosen among at least one amino acid and fatty acids.

New compounds of the general formula I wherein R' and R 2 each independently represent an alkyl group containing 1 to 4 carbon atoms, or an alkoxy group containing 1 to 3 carbon atoms, or halogen, R' represents hydrogen, halogen, an alkyl group containing 1 to 4 carbon atoms, an alkoxv group containing 1 to 3 carbon atoms, an amino group or a nitro group, A represents which is bonded to the benzene ring by its sulphu r or nitrogen atom and in which R' is hydrogen or an alkyl group containing to 4 carbon atoms; together with salts thereof with I physiologically acceptable acids and, when R' is hydrogen, with physiologically acceptable bases are described. The compounds are of use in inhibiting thrombosis formation, in treating thrombosis and in fibronolytic therapy. Various methods of producing the new compound are described involving the building up of the -A-CH 2 -CH 2 -S-CH 2 CH 2 -NH 2 side chain from aromatic precursors having an imcomplete side chain or by introducing at least one of R 1 , R or R'substituents into a precursor lacking that substituent or from an amino-protected precursor.
摘要:
A flexible transparent container for improved storage of oxygen sensitive parenterally administerable agents comprising an inner, primary container enclosed in a substantially oxygen impermeable outer envelope with an oxygen absorber, capable of consuming essentially all residual oxygen after the outer envelope is sealed, and for sufficient period also the oxygen penetrating said envelope. The inner container is made of a polypropylene containing flexible polymeric material compatible with lipophilic agents capable of forming both permanent and peelable seals, while the envelope is made of a substantially water impermeable flexible multilayered polymeric material comprising a first outer substantially water impermeable polymeric film with oxygen barrier forming capacity, assembled with a second, inner polymeric film with a supplementary oxygen barrier forming capacity. The container essentially maintains its characteristics after being subjected to sterilization by steam or radiation.

摘要:
The invention relates to a process of preparing pharmaceutical closures for containers made of flexible polymeric materials which are suitable to be filled with parenterally administerable fluids prior to their sealing and sterilization. The process involves a specific relaxation period for the elastomer material of the closure which thereby can settle and develop resealing characteristics. The closures will have an excellent resealing capacity after being penetrated by a piercing device for establishing fluid communication with the container, even after multiple entries into the container.
摘要:
A device for storing and administering a medical fluid comprising a sealed flexible formed container (10) with an opening part (12) in its front end in which an insert (20) is positioned. Over the insert, the container extends into a removable sealing cap (14). After removal of the sealing cap an injection means is attached to the insert and fluid administration through the insert is admitted in one direction by squeezing the container.
