All drugs produce various levels of unwanted side effects, and although most are predictable, some effects are linked to the individual’s health. Other triggers are a misuse of the medicine, incorrect doses, frequencies or improper applications. Clortrimazole is applied to the skin intended to treat the area because the skin absorbs the topical it can become systemic with serious side effects. The risks of severe side effects are low – but if you experience unusual or discomforting symptoms, contact your doctor.
Is Ignorance Always Bliss? Does knowing that one can control their own behaviour make it more likely that they will do so? In the short story, “Quarantine”, author Alix Ohlin illustrates the difference between self-awareness and oblivion, and how both characteristics can affect personal relationships. Ohlin portrays the idea that there are generally two types of people in life, those who are aware of their identity and those who are not aware, and that a person’s identity impacts the way others see them.
DOCETAXEL Docetaxel is an anti-mitotic chemotherapy medication that is used to treat breast, ovarian, lung cancer, docetaxel is given intravenously, docetaxel was first approved by the FDA IN 1996, 11 years ago docetaxel was approved again by the FDA on October 17th 2006, docetaxel binds to microtubules reversibly with high affinity. Docetaxel is well known under a brand name Taxotere, Docetaxel belong to a chemical called taxoid. Docetaxel promotes the formation of microtubules that do not function properly. Microtubules aid the replication of cells by disrupting this function and docetaxel inhibits cell replication. There is an active ingredient of 20mg and 80mg of taxotere.
OxyContin Emmanuela Brown Pharmacology Mr.JD Southern Technical College Have you ever thought of why people get additive to Pharmacia drugs. What are the street values of those drugs? Why are these drugs so important if various people are abusing and getting addictive to them? “Acadiana Addiction Center says, people get addicted, because it causes a Euphoric high caused by stimulation of the reward center of the brain (acandiana addiction center, n.d.). There is always someone going to abuse this drug, because of how it makes you feel.
The purpose of this experiment is to perform a two step reductive amination using o-vanillin with p-toluidine to synthesize an imine derivative. In this experiment, 0.386 g of o-vanillin and 0.276 g of p-toluidine were mixed into an Erlenmeyer flask. The o-vanillin turned from a green powder to orange layer as it mixed with p-toludine, which was originally a white solid. Ethanol was added as a solvent for this reaction. Sodium borohydride was added in slow portion as the reducing agent, dissolving the precipitate into a yellowish lime solution.
Minoxidil 's main role is to stimulate the blood circulation of hair follicles, improve hair follicle. Here with the simply introduce a few basic knowledge when using cosmetic raw material minoxidil solution to cure the male hair loss. The initial hair loss: topical minoxidil solution can cause initial mild hair loss to increase, because minoxidil already in the telogen hair loss, usually on the scalp hair in the telogen last 100 days fall, 10% of hair in telogen increased to 20%, but in the area of male pattern baldness, shrinking of hair follicles in the telogen, when minoxidil work for thinning hair, can explain why Minoxidil can cause hair loss, hair fall will be the repose of the end of the thicker, healthier hair to replace the other hand, the treatment of male pattern baldness will result in hair follicles gradually narrowing. On minoxidil resistance, misunderstanding, minoxidil will help restore the hair follicles, again in about two years (sometimes years) to grow thicker hair, more than this
Zika virus has made it’s way to the U.S. after starting out in Central and South America. Mosquitoes are the carriers of the virus which causes a problem for many that live in the Southeast United States and specifically in Miami Florida since there is an abundance of the nasty blood suckers there. Scientist however may have found a way to stop the spread of this disease a new genetically modified mosquito called OX513A which I believe is the way that we will be to stop the spread Zika virus and here is why. Zika virus is an illness that is spread through mosquitos when they bite you. Many people that are infected with Zika virus will have no or very mild symptoms.

SITE SPECIFIC DRUG DELIVERY Site specific delivery systems are unique forms of delivery systems whereby the drug or medicine is specifically or selectively delivered to a particular site in the body where it is going to exert it's action and it is not delivered to other non-target organs and cells. The main aim of site specific delivery of drugs is to develop drug concentration that is sufficient to produce therapeutic effect at the site of the disease with minimal effect to the rest of the organs, tissues and cells of the body. These site specific drug delivery systems act on a particular disease or anatomical area or organ to produce the desired therapeutic effect. For the drug to be delivered to a specific site there has to be a carrier,
