Purpose: To evaluate the super-disintegrant potentials of acid modified Borassus aethiopum starch (AMS) in comparison with native starch (NS) and commercial disintegrant sodium starch glycolate (SSG). Methods: Compatibility of AMS with paracetamol powder was evaluated using Fourier transform infrared (FTIR) spectrophotometry. Seven batches of paracetamol granules and tablets were prepared by wet granulation. AMS and NS were employed as disintegrants at concentrations of 2.43, 4.86 and 9.72 %w/w, respectively while 4.86 %w/w SSG was used as standard disintegrant. All the batches of the granules were compressed under the same compression settings. The properties of the granules as well as those of the tablets were assessed. Results: AMS was compatible with paracetamol powder as no noticeable interaction was observed in FTIR study. The paracetamol tablets formulated using AMS as disintegrant demonstrated satisfactory friability, weight uniformity, hardness, and superior disintegration characteristics to the formulations containing NS and SSG as disintegrant. Even at a lower concentration (2.43 %w/w), AMS possessed better disintegrant property than NS and SSG. AMS and NS had dimensionless disintegrant quantity of 1.447 and 0.005, respectively. As expected, increase in AMS concentration showed a decrease in disintegration time. Conclusion: AMS could be a potential low-cost super-disintegrant in formulation of paracetamol tablets.

Biomaterials are constructed to promote or stimulate the processes of wound healing. Polymeric biomaterials can be used to hydrate the wound and serve as barrier to pathogens with plant extracts, antimicrobial agents and extracellular components incorporated to stimulate the healing process. The biological and physical augmentation provided by extracellular matrix derived implants continues facilitate innovation in biomaterials utilized in management of nonhealing wounds. Tissue-processing methodologies can birth extracellular matrix-based devices with characteristic post-implantation responses ranging from the classic foreign body encapsulation of a permanent implant, to one where the implant is degraded and resorbed, to one where the processed extracellular matrix implant is populated by local fibroblasts and supporting vasculature to produce, a viable and metabolically active tissue. Extracellular matrix components and plant extracts have been shown to possesses pharmacological properties with potential for use in the treatment of skin diseases and wound healing. Antioxidant, anti-inflammatory assays, and wound healing assays have been shown to support the dermatological and wound healing usage of these medicinal plants extracts.
