Abstract: Extended dosage forms of stavudine are provided comprising beadlets formed by extrusion-spheronization and coated with a seal coating. The beadlets are also coated with a modified release coating such that a hard gelatin capsule containing such beadlets will provide blood levels of stavudine over approximately 24 hours. The beadlets are prepared from a dry blend of stavudine, a spheronizing agent, a suitable diluent and a stabilizing amount of magnesium stearate. The magnesium stearate, in contrast to other similar pharmaceutical adjuncts, has been found to stabilize stavudine against degradation due to hydrolysis in the presence of the limited amount of water necessary for the extrusion-spheronization process. Also included in the scope of the invention are hard gelatin capsules containing, in addition to the stavudine beadlets, similar beadlets containing other therapeutic agents utilized to treat retroviral infections.

Abstract: A high drug load spheronized beadlet is provided wherein said beadlet comprises about 80% to 100% by weight of an acid labile medicament, preferably didanosine, about 0% to about 10% by weight of a disintegrant, and about 0% to about 10% by weight of a binder selected from the group consisting of sodium carboxymethylcellulose, hydroxypropylmethylcellulose, potassium alginate, and partially pregelatinized corn starch. A high drug load pharmaceutical composition, comprising the beadlet, with an enteric coating disposed thereon, is also provided.

Abstract: A high drug load enteric coated pharmaceutical composition is provided which includes a core in the form of a tablet and which is comprised of a medicament which is sensitive to a low pH environment of less than 3, such as ddl, and having an enteric coating formed of methacrylic acid copolymer and a plasticizer. The tablets may be of varying sizes and may be orally ingested individually or a plurality of tablets sufficient to attain a desired dosage may be encapsulated in a dissolvable capsule. The tablets have excellent resistance to disintegration at pH less than 3 but have excellent drug release properties at pH greater than 4.5. A novel method of making said pharmaceutical composition is also disclosed.

Abstract: The present application relates to a series of compounds, and pharmaceutical formulations thereof, of the formula ##STR1## which provide a method of inhibiting hyperlipidemia, especially hypercholesterolemia, and the pathological sequelae thereof, in mammals, including humans.

Abstract: The present invention provides a method for producing a potentiating effect on a therapeutic action of an agent which is selected from a serotonin re-uptake inhibitor, a norepinephrine re-uptake inhibitors, both a serotonin and norepinephrine re-uptake inhibitor, and an atypical antidepressant in a warm blooded mammal, which comprises administering to said mammal an effective amount of moxonidine, or a pharmaceutically acceptable salt thereof.

Abstract: This invention provides novel indenone derivatives, their pharmaceutical formulations and their use for the inhibition of leukocyte adherence to cells.
