Pharmaceutical Properties of Nifedipine from a Ground Mixture with Nifedipine, Casein, Magnesium Silicate and Cellulose Acetate Phthalate.

Electrochemical Behaviour of Nifedipine and Nitrendipine in Chloroform and Chloroform-Isopropanol Mixture

The electrochemical behavior of nifedipine (I), nitrendipine(II) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (PPC) as supporting electrolyte. It has been shown that I and II undergo in a 4e, 4H+ irreversible reduction reaction, while the reduc...

Water dispersible microbicidal cellulose acetate phthalate film

BACKGROUND Cellulose acetate phthalate (CAP) has been used for several decades in the pharmaceutical industry for enteric film coating of oral tablets and capsules. Micronized CAP, available commercially as "Aquateric" and containing additional ingredients required for micronization, used for tablet coating from water dispersions, was shown to adsorb and inactivate the human immunodeficiency vi...

Electrokinetics and Stability of a Cellulose Acetate Phthalate Latex

An experimental investigation is described on the surface electric characterization of a commercially available latex, Aquateric, composed of cellulose acetate phthalate polymer particles, and used in enteric-controlled drug release. Since the surface charge of dispersed systems is an essential parameter governing most of their behavior, it is of fundamental importance to characterize how that ...
