Regulating drug release behavior and kinetics from matrix tablets based on fine particle-sized ethyl cellulose ether derivatives: an in vitro and in vivo evaluation.

Kifayat Ullah Shah et al.

TheScientificWorldJournal, 2012, 842348-842348 (2012-06-01)

The design and fabrication of sustained/controlled release dosage forms, employing new excipients capable of extending/controlling the release of drugs from the dosage forms over prolonged periods, has worked well in achieving optimally enhanced therapeutic levels of the drugs. In this

Low molecular mass chitosan as carrier for a hydrodynamically balanced system for sustained delivery of ciprofloxacin hydrochloride.

Anurag Verma et al.

Acta pharmaceutica (Zagreb, Croatia), 62(2), 237-250 (2012-07-04)

Chitosan has become a focus of major interest in recent years due to its excellent biocompatibility, biodegradability and non-toxicity. Although this material has already been extensively investigated in the design of different types of drug delivery systems, it is still

Polymer coating of carrier excipients modify aerosol performance of adhered drugs used in dry powder inhalation therapy.

Daniela Traini et al.

International journal of pharmaceutics, 438(1-2), 150-159 (2012-09-12)

The potential of excipient coating to enhance aerosol performance of micronized drugs in carrier excipient-drug blends, used in dry powder inhalers, was investigated. Both EC (ethyl cellulose) and PVP (polyvinylpyrrolidone) were used as coating agents. Carriers were prepared via sieve
