The average number of kickting attempts that majority of smokers try in their lifetime varies from 6 to 9 times (Pfizer, Inc. , 2007). The smoking cessation attempts ar often not successful because of faulty methodologies used in the endeavor. Majority of smokers efforts to quit atomic number 18 without usage of medical drugs. Thus, the meager success order of only 3 to 5 percent of the total yearly attempts.The availability of products like bupropion hydrochloride, nortriptyline hydrochloride, and nicotine renewal drugs manifests only modalityst accomplishments (Nides et al. , 2006). In line with this dilemma, a drug was manufactured to aide smokers in their quitting back with a step-by-step technique. This drug which is manufactured by Pfizer, Inc. is known for its brand name Chantix but its generic wine name is v benicline tartrate. This drug was manufactured to offer an eff ective support for smokers that want to quit this vice. Drug specifics and mode of actionVarenicline tartrate, the tartrate salt form of varenicline, posses the chemical name 7,8,9,10-tetrahydro-6,10-methano-6H-pyrazino2,3-h3benzazepine, (2R,3R)-2,3-dihydroxy- butanedioate (11). This substance which is the active ingredient of Chantix remarkably dissolves in water and has a white to slightly yellow color when in powered form. Varenicline has the molecular approach pattern C13H13N3C4H6O6 (RxList, Inc. , 2009). This drug is a non-nicotinic drug that targets the ? 4? 2 nicotinic receptor in the brain. It acts through with(predicate) blockage of nicotine from attaching to the ?4? 2 nicotinic receptor. These receptors are the same target of nicotine, a substance present in cigarette. The binding of nicotine with the ? 4? 2 nicotinic receptors after the smoker inhales cigarette smoke conveys a message to a specific fragmentize in the brain to pouch dopamine, the substance responsible for creating the pleasure feeling. The addiction to cigarette smoking is due(p) to short duration nature of the pleasurable feeling that is created by dopamine. The body yearns for more nicotine so that a simulation of the pleasurable feeling occurs again and again.Since varenicline prevents the binding of nicotine with its brain receptors the recess of this drug will eat the feeling of pleasure that a person experiences every time cigarette is smoked. Therefore, quitting of smoking is easier along with intake of varenicline because the act of smoking does not bring the good feeling anymore (Coe et al. 2005). Another positive specify of varenicline is its capacity to decrease the smoking withdrawal signs through its interaction with the dopamine receptors. This interaction results in the discharge of the horm singles that allows the individual to feel pleasure or feel-good hormones (Bullock, 2007).Thus, during varenicline medical specialty the smoker will not experience the p ortentous withdrawal symptoms because high amounts of feel-good hormones are distributed in his or her blood. Pre anxietys and side effects The adverse reactions associated with the intake of varenicline are dizziness nausea headache fatigue behavioral changes like depression and crankiness boosted appetite excrete decreased bowel motility flatulence and, sleeping problems. This drug can not be interpreted along with cimetidine because the latter will amplify varenicline levels in the plasma.Insulin blood thinners like warfarin or coumadin and theophylline are other therapeutic medicines prohibited during varenicline medication (MSN health and fitness). Precautions that require to be observed during varenicline medication are consultation with a physician about the proper window pane and duration of therapy monitoring of behavioral changes during the medication period this drug is not good for individuals whom are downstairs 18 years old, pregnant, and breast feeding mothers th e intake of this drug may also alter the achievement of specialized tasks and, medication should be after food ingestion (MIMS, 2009).Further precautions indicated in the use of this drug are non- usage among people with history of mental disease and kidney problems compliance with proper dosage prescribe by the doctor and, observance of prescription label (MSN health and fitness). Efficacy of varenicline therapy According to its manufacturer, varenicline medication has the smoking quitting success rate of 44 percent while sugar pills only have 18 percent efficacy (Pfizer, Inc. , 2007). In a study conducted by Nides et al.(2006) comparing varenicline with bupropion a significantly high success rate among varenicline medicated subjects was observed. The efficacy of this drug in the said study was 21. 9 percent, whereas, bupropion only had 16. 1 percent. Another study which proves the capacity of this drug to increase the success rate of smoking cessation is that one done by Cahill et al. (2007). It is noted in the said study that varenicline triples the achievement of smoking termination as compared to those who are medicated with antidepressants or had no medications at all.Issues on varenicline medication Among the issues that are coupled with the medication of varenicline are the harsh side effects like hallucinations and the alterations in the perception of joy. A varenicline medicated individual reported that during his therapy with varenicline he experienced intense hallucinations as well as alterations in his fulfillment after activities that can supposedly make an individual happy.

This drug is also accounted to amplify psychiatrical conditions like schizophrenia and bipolar disorder. These reports were already reported to FDA thus the advice of this agency to take tremendous caution when prescribing and taking varenicline (FDA, 2007).Biochemical Pathway The maximum plasma concentration of varenicline is attained 3 4 hours offer oral intake of the drug. This drugs bioavailability is high after oral intake and is not change by the dosing time and the presence or absence of food. Varenicline though has a plasma protein binding that is below or equal to 20 percent. It takes an estimate of 24 hours for the half-life elimination of this drug to take attribute and negligible metabolism was observed (RxList, Inc. , 2009). ConclusionDespite the side effects that are said to be attributed to the administration of varenicline, this drugs efficacy as a smoking cessation aide clay to be unaffected. Al nearly all of the available drugs have side effects thus it is not dreadful for varenicline to also have some side effects. That is why precautions are available to eliminate the occurrence of most of a drugs side effects. The proper observance of all the precautions indicated for this drug ensures that the person undergoing varenicline therapy and smoking cessation endeavor will have no health problems attributable to the medication.The weight of support that this drug can lend to the smokers who are trying to leave their deadly vice (smoking) is significantly higher as compared to the risks of side effects manifestation during the therapeutic period. Thus, cessation of smoking can be made easier through the aide of varenicline tartrate (Chantix ).Reference ListBullock, Carole. (2007).
