An Overview on Biomaterials: Pharmaceutical and Biomedical Applications

The development of biomaterials have existed from around half a century and manifest its use in different fields. Biomaterials are used in living creature body, looking on its biocompatibility nature. In recent years, advances of biomaterials are showing a marked presence in the fast growing fields of pharmaceuticals and medicines. According to their availability, different types of biomaterials like metal, ceramic, polymer and their composites are used for several purpose in the body. In this review article, types of biomaterials have been discussed with their advantages, disadvantages and recent applications in the pharmaceutical field such as implants used to mimic the structure and function of tissues, dental implants, wound healing, cell regeneration, regenerative medicines, delivery of drugs and different organ regeneration. Organ regeneration leading to replacement of organs such as heart, trachea and lungs etc. by use of specific biomaterials have been reported with the diagnosis of diseases and its treatment

Development and assessment of rutin loaded transfersomes to improve ex vivo membrane permeability and in vitro efficacy

The melanoma is the most dangerous kind of skin cancer begins in the melanocytes, or cells that make melanin, the pigment that gives your skin its color. Due to the need of local effect topical administration of anticancer drugs could be the best option for clinical therapy. Present study aimed to formulate transfersomes to enhance the skin penetration of rutin (Rtn). Rutin loaded transfersomes (RtnTFs) were formulated by employing central composite design (CCD) of experiment and comprising of various ratios of phospholipid 90H and sodium deoxycholate as independent variables. The assessment of critical parameters suggested higher encapsulation of Rtn and improved stability of formulation with significant drug release (P < 0.05). The RtnTFs shows higher cell inhibition on Murine skin Melanoma cell line (B16–F10). Further, formulated RtnTFs were incorporated in transdermal patches (TPs) to enhance skin deposition. However the higher deposition of about 0.921 ± 0.23 mg/cm3 of Rtn was observed. RtnTFs-TPs exhibited ideal morphological characteristics in scanning electron microscopic images. Ex-vivo skin diffusion studies revealed the sustained release of about 98 ± 0.26 % drug at the end of 36 h (P < 0.05). Skin irritancy study demonstrated the suitability of RtnTFs-TPs for dermal delivery and with higher stability. Hence the topical delivery with delayed release of drug by enhancing the solubility could be the promising strategy for efficient delivery of anticancer agents

Agmatine: A potential Neurotherapeutic Agent

Agmatine, a natural polyamine disregarded almost for over 100 years, was discovered in year 1910. Almost after a decade, several researches on Agmatine indicated its modulatory action at multiple molecular targets such as, nitric oxide synthesis, neurotransmitter systems, and polyamine metabolism unbolt the new avenues for extensive therapeutic applications which includes neurotrauma and neurodegenerative diseases, antidepressant, cognitive disorders. Agmatine exerts its varied biological characteristics and therapeutic potential in diverse arena. Agmatine has been extensively researched for its neuroprotective effect in various types of neurological diseases, including stroke and trauma brain injury along with Parkinson's disease, Alzheimer's disease, Hypoxia /Ischemia. In the present review we have summarized the therapeutic potential of agmatine as protective and regenerative properties in the CNS.
