Chantix Start Month Pak Uses, Dosage, Side Effects, Food Interaction and all others data.

Chantix Start Month Pak binds with high affinity and selectivity at α4β2 neuronal nicotinic acetylcholinereceptors. The efficacy of Chantix Start Month Pak in smoking cessation is believed to be the result of varenicline's activity at α4β2 sub-type of the nicotinic receptor where its binding produces agonist activity, while simultaneously preventing nicotine binding to these receptors.Electrophysiology studies in vitro and neurochemical studies in vivo have shown that varenicline binds to α4β2 neuronal nicotinic acetylcholine receptors and stimulates receptor-mediated activity, but at a significantly lower level than nicotine. Chantix Start Month Pak blocks the ability of nicotine to activate α4β2 receptors and thus to stimulate the central nervous mesolimbic dopamine system, believed to be the neuronal mechanism underlying reinforcement and reward experienced upon smoking. Chantix Start Month Pak is highly selective and binds more potently to α4β2 receptors than to other common nicotinic receptors ( >500-fold α3β4, >3,500fold α7, >20,000-fold α1βγδ), or to non-nicotinic receptors and transporters (> 2,000-fold). Chantix Start Month Pak also binds with moderate affinity (Ki = 350 nM) to the 5-HT3 receptor.

Chantix Start Month Pak is a partial nicotinic acetylcholine receptor agonist, designed to partially activate this system while displacing nicotine at its sites of action in the brain.

Uses

Chantix Start Month Pak is used for use as an aid to smoking cessation treatment.

Chantix Start Month Pak is also used to associated treatment for these conditions: Cessation, Smoking

How Chantix Start Month Pak works

Chantix Start Month Pak is an alpha-4 beta-2 neuronal nicotinic acetylcholine receptor partial agonist. The drug shows high selectivity for this receptor subclass, relative to other nicotinic receptors (>500-fold alpha-3 beta-4, >3500-fold alpha-7, >20,000-fold alpha-1 beta gamma delta) or non-nicotinic receptors and transporters (>2000-fold). The drug competitively inhibits the ability of nicotine to bind to and activate the alpha-4 beta-2 receptor. The drug exerts mild agonistic activity at this site, though at a level much lower than nicotine; it is presumed that this activation eases withdrawal symptoms.

Dosage

Chantix Start Month Pak dosage

Smoking cessation therapies are more likely to succeed for patients who are motivated to stop smoking and who are provided additional advice and support. Provide patients with appropriate educational materials and counseling to support the quit attempt.The patient should set a date to stop smoking.

Half Life

The elimination half-life of varenicline is approximately 24 hours

Elimination Route

Chantix Start Month Pak undergoes minimal metabolism, with 92% excreted unchanged in the urine. Renal elimination of varenicline is primarily through glomerular filtration along with active tubular secretion possibly via the organic cation transporter, OCT2.

Pregnancy & Breastfeeding use

Use in Pregnancy: Category C. There are no adequate and well-controlled studies in pregnant women. Chantix Start Month Pak should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus

Use in Lactation: It is unknown whether varenicline is excreted in human breast milk. Animal studies suggest that varenicline is excreted in breast milk. A decision on whether to discontinue breast-feeding or to discontinue therapy with varenicline should be made taking into account the benefit of breast-feeding to the child and the benefit of varenicline therapy to the woman

Contraindication

Known hypersensitivity to varenicline or to any of the excipients in the product (microcrystalline cellulose, dibasic calcium phosphate, anhydrous, croscarmellose sodium, colloidal silicon dioxide, magnesium stearate, Opadry Blue/White and Opadry Clear).
