An implantable device for delivery of a macromolecular drug compound is provided. The device comprises a core having an outer surface and a membrane layer positioned adjacent to the outer surface of the core. The core comprises a core polymer matrix within which is dispersed a drug compound having a molecular weight of about 0.5 kDa or more, the polymer matrix containing a hydrophobic polymer. Further, the membrane layer comprises a membrane polymer matrix within which the macromolecular drug compound is optionally dispersed. The concentration of the macromolecular drug compound in the core is greater than the concentration of the macromolecular drug compound in the membrane layer.

The present invention aims to provide a preparation containing a compound of the formula [I] or a pharmaceutically acceptable salt thereof or a hydrate thereof having improved pharmacokinetics, and a manufacturing method thereof. The present invention relates to a solid dispersion containing (1) an amorphous compound represented by the following formula [I]:

##STR00001##

or a pharmaceutically acceptable salt thereof or a hydrate thereof, and

(2) one to four kinds of pharmaceutically acceptable polymers selected from the group consisting of hydroxypropylmethylcellulose acetate succinate, methylcellulose, hypromellose and polyvinyl alcohol, and a manufacturing method thereof.

Provided herein are fixed-dose combination formulations of a pharmaceutically effective amount of eflornithine together with a pharmaceutically effective amount of sulindac. Also provided are methods of use and of methods of manufacture of these formulations.

The present invention discloses a novel film coating composition of polyvinyl alcohol (PVA) in combination with sugar, and a plasticizer or a combination of plasticizers resulting in a composition which is non tacky and easily dispersible in water at high solids content. The coating compositions help in achieving higher spray rates, disperse in less solvent i.e water, and helps in reduction of coating process time. Further the resultant film which when coated onto substrates exhibits good adhesion and provides smooth surface to substrates.

The present invention relates to a gastro-resistant pharmaceutical composition comprising a solid solution prepared by hot-melt extrusion, whereby the solid solution contains posaconazole, an enteric polymer and a non-enteric polymer. The composition is preferably a granulate material that can be filled into a capsule or compressed into a tablet.

Methods of improving visual endpoints related to retina-associated disease with CCR3 modulating agents are provided. An example of such an endpoint is visual acuity. Retina-associated diseases upon which visual acuity and other visual endpoints may be improved include retinopathy of prematurity, age-related macular degeneration, central retinal vein occlusion, and diabetic retinopathy.

An oseltamivir formulation and a preparation method of the formulation, the method being simple to operate, having good reproducibility, and being suitable for manufacture. The oseltamivir formulation includes oseltamivir or a salt thereof and a sustained-release material. The formulation may be a single-phase release formulation, a dual-phase release formulation, a three-phase release formulation, or a multi-phase release formulation having more than three phases. The formulation is administered once-daily and can achieve sustained release of at least 24 hours or longer, which can reduce the times of administration and avoid peak-to-valley fluctuations, thereby improving the compliance and safety of patients.

The present disclosure relates to the field of pharmaceutical chemistry, and particularly to a compound represented by Formula (I), a preparation method and medical use thereof. In the compound represented by Formula (I), a lactulosyl group is connected to a heteroatom of genin (G) via a glycosidic bond, wherein the genin (G) is a group formed by removing one hydrogen atom from a heteroatom of an active pharmaceutical molecule, and “” indicates that the lactulosyl group is connected to the heteroatom of the genin (G) via an α-glycosidic bond or a β-glycosidic bond. Pharmacokinetic experiments prove that the lactuloside compound according to the present disclosure can pass through the gastrointestinal tract of a mammal without being absorbed significantly by the gastrointestinal tract and hydrolyzed significantly by endogenous enzymes of a mammal host. Therefore, the lactuloside compound can arrive at the colon site of the mammal, and release an active drug in the colon under the action of colon flora. The lactuloside compound has a function of colon-localized drug release, and can be used for preventing or treating an intestinal disease. ##STR00001##
