During the space travel mission, astronauts' physiological and psychological behavior will alter, and they will start consuming terrestrial drug products. However, factors such as microgravity, radiation exposure, temperature, humidity, strong vibrations, space debris, and other issues encountered, the drug product undergo instability This instability combined with physiological changes will affect the shelf life and diminish the pharmacokinetic and pharmacodynamic profile of the drug product. Consequently, the physicochemical changes will produce a toxic degradation product and a lesser potency dosage form which may result in reduced or no therapeutic action, so the astronaut consumes an additional dose to remain healthy. On long-duration missions like Mars, the drug product cannot be replaced, and the astronaut may relay on the available medications. Sometimes, radiation-induced impurities in the drug product will cause severe problems for the astronaut. So, this review article highlights the current state of various space-related factors affecting the drug product and provides a comprehensive summary of the physiological changes which primarly focus on absorption, distribution, metabolism, and excretion (ADME). Along with that, we insist some of the strategies like novel formulations, space medicine manufacturing from plants, and 3D printed medicine for astronauts in longer-duration missions. Such developments are anticipated to significantly contribute to new developments with applications in both human space exploration and on terrestrial healthcare. [ABSTRACT FROM AUTHOR]

This review focuses on the epigenetic factors that play a vital role in the formation of plaques and lead to atherosclerosis and related diseases in humans during current times. Apart from the epigenetics there are plenty more factors that influence the atherosclerotic risk in the older population of the current era. Lack of physical activities has become one of the most commonly found traits that causes obesity in people especially the middles aged adults. People working 9 - 5 in an office, or an IT firm tend spend idle time with their computer for 4 - 5 consecutive hours with barely changing their position. Lack of exercise tends to affect not only the physical health but also stress a person mentally. Chronic inflammatory diseases like atherosclerosis have a major role in the morbidity and mortality from cardiovascular disease worldwide. Atherosclerotic plaques are created by the pathophysiological process of lipids, inflammatory cells and fibrous components gradually accumulating within artery walls. Endothelial dysfunction signals the start of atherosclerosis and allows low-density lipoproteins (LDL) to enter the subendothelial region. Oxidative stress-induced changes in retained low-density lipoprotein (LDL) set off an inflammatory cascade that draws T cells and monocytes to the site of the lesion. The interaction of these immune cells with the local vascular cells encourages the production of foam cells, which fills the plaque's centre with lipids. Smooth muscle cells multiply and help produce fibrous caps as the lesion ages, which affects the stability of the plaque. Studies shows how the brain responds to physical labour and how differently the effectively the enzymes and hormones are secreted, and their actions are vastly guided based on the physical stress an individual undergoes. Among the most prominent causes of atherosclerosis epigenetics has been focused majorly in this review, where we focus on the underlying genetic factors that play a vital role in atherosclerosis and related cardiovascular diseases and also the genetic approach to a treatment is also elaborated. A number of miRNAs are involved in the cause/cure for the atherosclerosis, the following tables give an outlook regarding the same. This review aims to focus on the causes, risk factors, pathophysiology and the treatment and therapies that are currently available all the way concentrating on the genetic approach in the above-mentioned perspective.
