Starch-based release modifying excipients and pharmaceutical compositions derived therefrom

There is provide an extended release dosage form comprising a release modifying excipient comprising high amylose starch, cross-linked hydroxypropylated amylopectin, and a pre-gelatinized common starch; wherein the release modifying excipient is substantially free of crosslinks between amylose and amylopectin and substantially free of crosslinks between amylose and amylose. It has been found that the extended release properties of conventional cross-linked high amylose starches (e.g., Contramid®) can be reproduced by intimately mixing i) cross-linked chemically modified amylopectin; ii) a high amylose, non-chemically modified starch and; iii) a pre-gelatinized common starch. Producing a release modifying excipient in this way means that no chemical cross linking between (a) amylose and amylopectin or (b) amylose and amylose has occurred—properties heretofore considered vital for Contramid® function. The release modifying excipient blends overcome problems associated with use of Contramid, and provide a flexible platform for formulation of active pharmaceutical ingredients for controlled release applications.

20220387309 · 2022-12-08 ·

Orally adhering lozenges comprising soluble dietary fiber are provided herein. The orally adhering lozenges provided herein may be in the form of tablet-type lozenges comprising compressed powders and/or granules in at least two layers. The orally adhering lozenges include at least 30% soluble dietary fiber. The orally adhering lozenges also include an adhesive component to adhere the lozenge inside the mouth. The orally adhering lozenges are also low in cariogenic sugar, non-resistant starch, and polyols.

Compositions of different densities for fast disintegrating multi-layer tablet

Described herein is a method for forming multi-layer drug dosage forms having at least two layers. In the method, a first formulation comprising a non-gelling matrix forming agent and having a first density is dosed into a preformed mold. A second formulation comprising a non-gelling matrix former and having a second density not equal to the first density is subsequently dosed into the preformed mold. Then, the combination of the formulations dosed into the mold is freeze dried to form the multi-layer dosage form having at least two layers. The use of a density difference between the first and second formulations ensures formation of a product with two distinct layers.

Disclosed are a solid preparation, and a preparation method therefor and the use thereof. The solid preparation comprises an immediate-release part and a sustained-release part, which contains active ingredients, wherein the weight ratio of the active ingredient in the sustained-release part to the active ingredient in the immediate-release part is 1:1 or higher. In particular, the solid preparation is a tofacitinib preparation.

PHARMACEUTICAL COMPOSITE FORMULATION COMPRISING PROTON PUMP INHIBITOR AND ANTACID

An aspect provides a pharmaceutical composite formulation containing: a first layer comprising a proton pump inhibitor or a pharmaceutically acceptable salt thereof as an active ingredient, a disintegrant, and a binder; and a second layer comprising, as an active ingredient, an antacid selected from magnesium hydroxide, magnesium oxide, or a mixture thereof.

OSELTAMIVIR FORMULATION

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.
