Abstract

Hibiscus rosasinensis (HR) is a shrub belonging to Malvaceae. The leaves of ethanolic extract of HR exhibited antidiabetic activity. Mucilage is present in leaves of HR. The objective of this research is to extract and evaluate the mucilage of HR. Leaves were collected and slurry was prepared which was precipitated using ethanol. The precipitates were separated and dried. The dried mucilage was subjected to various phytochemical and physicochemical tests. The extracted mucilage shows the presence of carbohydrates, reducing sugar and mucilage whereas glycoside, alkaloids, steroids, flavonoids and tannins was absent. The moisture sorption test reveals that the mucilage can sorbed moisture and has ability of swelling in water as shown by result of swelling index test. Other physicochemical studies indicate that the mucilage has properties to be used as excipient. FTIR spectrum shows the presence of various functional groups and bonds it possesses. It can be concluded that the mucilage can be used to prepare dosage form. However, as it can absorb moisture, the prepared dosage form should be packed suitably to avoid the contact of moisture.

Abstract

Mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. Several synthetic polymers are in use for this purpose. Since the biodegradability of the synthetic polymers are questionable, in this investigation an oral mucoadhesive controlled delivery system has been developed for terbutaline sulphate (TS) using natural mucoadhesive materials extracted from the edible fruits like Zizyphus mauritiana (ZM) and Aegle marmelos (Linn.) Cor. (AM) that have better mucoadhesive property than synthetic polymer hydroxypropylmethylcellulose K4M (HPMC K4M). The in vitro adhesive and mucoadhesive strength of mucoadhesive materials extracted from the fruits of ZM and AM were evaluated and compared with HPMCK4M using both Share Stress and Wilhelmy Plate. Different formulations of oral mucoadhesive coated TS tablets were prepared using these natural materials and compared with tablets prepared with HPMCK4M and hardness, thickness, friability, weight variation and drug content of tablets were tested. The in vitro release of TS was studied in buffer pH 7.2 at 37°C ± 0.5°C. Tablets were orally administered to rabbits and blood plasma concentration of TS was determined using HPLC. It was found that mucoadhesive materials extracted from the fruits of ZM and AM exhibited better adhesiveness and mucoadhesiveness as compared with the HPMC- K4M. The in vitro study of TS exhibited showed greater drug release profile for tablets prepared with natural materials than synthetic polymers and confirmed with in vivo study. In vitro and in vivo correlation showed the same release profile.

Abstract

The objective of any formulation is to deliver drug to the patient in the definite amount, at the required rate, and maintains the stability of drug over the product's shelf life. To produce a drug formulation in a final dosage form, a number of pharmaceutical ingredients are required. In selecting excipients for pharmaceutical dosage forms and drug products the development pharmacist should be certain about the existing standards and safety parameters of the excipients. This will assure the consistent quality and functioning of the excipient. The selection and testing of non active ingredients or excipient in the design of drug dosage form present to the formulator the challenge of predictive foresight. While the ability to solve problems when they occur is a valuable attribute, the ability to prevent the problem through adequate experimental design is a virtue. The safety and biodegradability issues related to synthetic excipients have necessitates development of new natural excipients. Newer excipients provide the means for simplifying formulation development, and improving overall operational costs while preserving the quality that is expected by the industry. This review focuses on need to develop such newer natural excipients which shall be utilized to develop efficient dosage forms and the economics involved in doing so.
