  • Patent number: 4808413
    Abstract: A pharmaceutical composition is provided which is in the form of a plurality of beadlets, adapted to be filled into pharmaceutical hard shell capsules, or compressed into tablets, which beadlets are formed of a pharmaceutical such as an ACE inhibitor, for example, captopril, a beta-blocker such as nadolol, propranolol or atenolol, a calcium channel blocker such as diltiazem or nifedipine or other pharmaceuticals including combinations thereof, binder such as microcrystalline cellulose, and at least 5% by weight of an acid processing aid, such as citric acid, which imparts plasticity to the wet mass needed for efficient extrusion and spheronization. A method for forming beadlets is also provided which includes the steps of extruding a composition as described above, and subjecting the resulting extrudate to a spheronization step wherein an acid processing aid such as citric acid is employed to improve processing and form improved beadlets.

  • Patent number: 4804770
    Abstract: A process is provided for preparing the keto-phosphonate ##STR1## in enantiomerically homogeneous form, by reacting the anhydride ##STR2## with S-.alpha.-methylbenzylamine to effect diastereoselective opening of the anhydride to give a mixture of amides ##STR3## separating the amides, for example, by frictional crystallization, and converting the desired amide IVA (which is obtained in high yield from the anhydride) to enantiomerically homogeneous ketophosphonate in high yield and on a large scale.The so-formed ketophosphonate is useful in the synthesis of compactin as well as 7-substituted-(3,5-dihydroxy)-hept-6-enoic and -heptanoic acid HMG-CoA reductase inhibitors.

  • Patent number: 4801297
    Abstract: The present catheter employee a series of axial slits adjacent to its tip. The slits act to increase the flexibility of the catheter adjacent the tip thereby providing pressure relief in the event of blockage of the lumen at the tip. In addition, by forming the slits as slots, i.e. by removing material from the slits, it is possible to provide a catheter having flow through the sides adjacent to the tip for any desired purpose.

  • Patent number: 4795439
    Abstract: An improved multi-lumen catheter having lumens which do not extend in a straight line down the length of the catheter is disclosed. The twisting of the catheter provides that side holes which extend into the lumens of the catheter are not aligned in a straight line. Accordingly, when the catheter is inserted into a patient's vessel, the side holes cannot be aligned in a manner which causes all of the side holes of a particular lumen to be occluded by the wall of the patient's vessel.A catheter of the type disclosed can be manufactured by an extrusion process in which the catheter is twisted during the extrusion, or by heating a non-twisted catheter and then twisting it in order to impart an appropriate twist therein.
