Herbal excipients in novel drug delivery systems

Abstract

The use of natural excipients to deliver the bioactive agents has been hampered by the synthetic materials. However advantages offered by these natural excipients are their being non-toxic, less expensive and freely available. The performance of the excipients partly determines the quality of the medicines. The traditional concept of the excipients as any component other than the active substance has undergone a substantial evolution from an inert and cheap vehicle to an essential constituent of the formulation. Excipients are any component other than the active substance(s) intentionally added to formulation of a dosage form. This article gives an overview of herbal excipients which are used in conventional dosage forms as well as novel drug delivery systems.

Applications of natural polymers in mucoadhesive drug delivery: An overview

“…The cost of polymer should not be very high so that the prepared dosage form remains competitive (Girish et al, 2009). Shirwaikar et al, 2008 1. They are easily to microbial degradation.…”

Herbal excipients in Novel Drug Delivery Systems

“…• Heavy metal contamination -There are chances of Heavy metal contamination often associated with herbal excipients [5,6].…”

“…These ingredients play their role in the formulation as depicted in remark column of Table 2 and thus involve in framing of dosage form or in pharmacokinetics or supportive pharmacodynamics along with main ingredients of formulation. 28 . Both synthetic and natural polymers are available but the use of natural polymers for pharmaceutical applications is attractive because they are economical, readily available and non-toxic.…”
