Use of .BETA.-Cyclodextrins to Prevent Modifications of the Properties of Carbopol Hydrogels Due to Carbopol-Drug Interactions.

Chemical and Pharmaceutical Bulletin, 2002
Carbomers are carboxyvinylic derivatives that are widely used in the manufacture of hydrogel dosage forms. Because of their anionic nature and large number of acid groups, they tend to interact with cationic substances, and with other hydrophilic polymers containing alcohol groups.

Preparation of Solid Dispersion for Ethenzamide-Carbopol and Theophylline-Carbopol Systems Using a Twin Screw Extruder.

Chemical and Pharmaceutical Bulletin, 2002
In the present study, we prepared solid dispersions of water-insoluble and soluble drugs (ethenzamide (ETZ) and theophylline (THEO)) by the twin screw extruder method, which made it possible to control both kneading and heating at the same time under the fusion point of each drug, using three types of the controlled-release high-molecular-weight ...

Carbopol-Based Gels for Nasal Delivery of Progesterone [PDF]

AAPS PharmSciTech, 2008
The purpose of this study was to investigate the nasal absorption of progesterone from carbopol-based nasal gels in rabbits. Progesterone nasal gels were prepared by dispersing carbopol 974 (1%, 1.5%, and 2%) in distilled water followed by addition of progesterone/progesterone-beta cyclodextrin complex dissolved in propylene glycol then neutralization.

Up to 16% Optical Carbon‐13 Hyperpolarization of Donor–Acceptor Molecules at 14.1 T

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Up to 16% 13C nuclear polarization is achieved using a rationally designed photo‐CIDNP polarizing agent (PA) in magic‐angle‐spinning NMR experiments at 14.1 T. The PA was designed using a combination of theoretical photocycle calculations and magnetic field dependent experiments to identify important new design principles.
