"Drug Patch Design"

Download file to see previous pages The patch I shall design would work for at least 60hours at a stretch and would work on all types of skin. Here I shall examine the rates of design patch on fast skin and slow skin to help me come up with an efficient design for all. The parameters that I shall be controlling and altering are membrane thickness L, diffusivity D, and the concentration of Scopolamine in the reservoir Cp.
The second layer acts as the reservoir in which the drug is added in a predetermined concentration. It is from this layer that the drug would diffuse into the layer layers and ultimately into he skin. The final layer which would stay in touch with the skin of the wearer would be membranous and permeable such the drug can easily diffuse out of the patch and into the skin.
When the patch is put on, the drug slowly diffuses out of its layer into the next layer and travels right down to the skin layer and diffuses through it. It crosses the body barriers and enters the blood stream continuously thereby ensuring that the astronauts would not suffer from motion sickness as long as they wear a working patch.
I plotted the graph of concentration versus time in the body to understand which concentration lasted longer in the body since my aim was at least 60 hours.From these plots I selected the best effective concentration. All this was studied for maximum diffusivity (D2) and fast skin (l2).
The main purpose is to design a perfect patch which can be worn by all astronauts and which would work efficiently for a long stretch of time. If the time it is required to work for is less than or exceeds its requirement the patch would not be usable. On the other hand another rimportanat factor would be the concentration since a slightly higher concentration may have negative side effects on the astronauts.
The several layered patch would last for a long time thereby supplying the drug to astronauts in order to curb motion sickness passed simulation tests and could now be used ...Download file to see next pagesRead More

Drug Addiction
Julien et al. (2010) and Selye (1978) consider introduction of a foreign material to the body as one cause of deviation from this normalness. Exposing systems of an individual to a foreign material over a long period results to addiction. That is, addicts of a particular substance develop the behavior after being exposed to the substance over some time.

Chemotherapy and drug drug design
Iron is a part of several macromolecules in the human body involved with production of energy by the formation of adenosine triphosphate molecules, ribonucleoside reductase activity in DNA synthesis and xenobiotic metabolism (He et al, 2007; MacKenzie et al, 2007).The macromolecules consist of hemoglobin, cytochromes, oxygenases, flavoproteins, and redoxins. This makes iron a significant part of the vital biologic processes in human beings. Iron has a dichromatic nature; it is able to participate favourably in production of energy by electron transfer and can be simultaneously toxic by electron transfer in oxidation-reduction reactions (MacKenzie et al, 2007).
