Nicorette Microtab or Boots NicAssist
Nicorette Microtab or Boots NicAssist Uses, Dosage, Side Effects, Food Interaction and all others data.
Nicorette Microtab or Boots NicAssist, a pyridine alkaloid, is a stereo-selective nicotinic-cholinergic receptor agonist. Low doses cause an initial stimulation of autonomic ganglia, adrenal medulla, neuromuscular junction, and brain. High doses produce initial ganglionic stimulation followed by inhibition of neurotransmission leading to subsequent persistent depression of receptor activity.
Nicorette Microtab or Boots NicAssist, the primary alkaloid in tobacco products binds stereo-selectively to nicotinic-cholinergic receptors on autonomic ganglia, the adrenal medulla, neuromuscular junctions and in the brain. Nicorette Microtab or Boots NicAssist exerts two effects, a stimulant effect exerted at the locus ceruleus and a reward effect in the limbic system. Itranvenous administration of nicotine causes release of acetylcholine, norepinephrine, dopamine, serotonine, vasopressin, beta-endorphin and ACTH. Nicorette Microtab or Boots NicAssist is a highly addictive substance. Nicorette Microtab or Boots NicAssist also induces peripheral vasoconstriction, tachycardia and elevated blood pressure. Nicorette Microtab or Boots NicAssist inhalers and patches are used to treat smoking withdrawl syndrome. Nicorette Microtab or Boots NicAssist is classified as a stimulant of autonomic ganglia.

How Nicorette Microtab or Boots NicAssist works
Nicorette Microtab or Boots NicAssist is a stimulant drug that acts as an agonist at nicotinic acetylcholine receptors. These are ionotropic receptors composed up of five homomeric or heteromeric subunits. In the brain, nicotine binds to nicotinic acetylcholine receptors on dopaminergic neurons in the cortico-limbic pathways. This causes the channel to open and allow conductance of multiple cations including sodium, calcium, and potassium. This leads to depolarization, which activates voltage-gated calcium channels and allows more calcium to enter the axon terminal. Calcium stimulates vesicle trafficking towards the plasma membrane and the release of dopamine into the synapse. Dopamine binding to its receptors is responsible the euphoric and addictive properties of nicotine. Nicorette Microtab or Boots NicAssist also binds to nicotinic acetylcholine receptors on the chromaffin cells in the adrenal medulla. Binding opens the ion channel allowing influx of sodium, causing depolarization of the cell, which activates voltage-gated calcium channels. Calcium triggers the release of epinephrine from intracellular vesicles into the bloodstream, which causes vasoconstriction, increased blood pressure, increased heart rate, and increased blood sugar.
Dosage
Nicorette Microtab or Boots NicAssist dosage
Buccal:As chewing gum containing 2 mg or 4 mg nicotine polacrilex: Smokers of ≤20 cigarettes daily: Start with 2 mg chewed slowly and parked between cheek and gum over 30 min when urge to smoke occurs.

Nicorette Microtab or Boots NicAssist Disease Interaction
Major: CVD/PVD, pheochromocytomaModerate: diabetes, hyperthyroidism, liver disease, PUD
Volume of Distribution
- 2 to 3 L/kg
Elimination Route
Absorption of nicotine through the buccal mucosa is relatively slow and the high and rapid rise followed by the decline in nicotine arterial plasma concentrations seen with cigarette smoking are not achieved with the inhaler. About 10% of absorbed nicotine is excreted unchanged in urine.
Half Life
Cotinine has a half life of 15-20 hours, while nicotine has a half life of 1-3 hours
Clearance
- 1.2 L/min [healthy adult smoker]
Elimination Route
About 10% of the nicotine absorbed is excreted unchanged in the urine.
Pregnancy & Breastfeeding use
Pregnancy Category D. There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
Contraindication
Recent cerebrovascular accident. Self-medication in patients who will continue to smoke, chew tobacco, or use snuff or other nicotine-containing preparations. Non-smokers and occasional smokers.
Acute Overdose
Symptoms: Burning of the mouth and throat, nausea, vomiting, salivation, abdominal pain, diarrhoea, sweating, headache, dizziness, hearing and visual disturbances, weakness, confusion, syncope, prostration, dyspnoea, tachycardia, hypotension, rapid or weak or irregular pulse, seizure, resp failure, circulatory collapse, coma.
Management: Symptomatic and supportive treatment. Artificial respiration is instituted if necessary. Employ activated charcoal to reduce GI absorption. For TTS, the skin should be washed with water without using soap and dried.
