Special Precautions
Patient w/ CV disease (e.g. MI, severe arrhythmia, unstable angina pectoris, CVA, uncontrolled HTN), peripheral vascular disease, endocrine disorder (e.g. phaeochromocytoma, hyperthyroidism, DM), peptic ulcer, and skin disease (patch). Hepatic and renal impairment. Childn. Pregnancy and Lactation. Monitoring Parameters Monitor cardiac status, vital signs and blood sugar levels.
Adverse Reactions
Nausea, vomiting, abdominal pain, diarrhoea, headache, dizziness, hiccups, flu-like symptoms, palpitations, insomnia, vivid dreams, myalgia, chest pain, anxiety, irritability, somnolence, dysmenorrhoea; mouth (e.g. aphthous ulceration) and throat irritation; nasal irritation, epistaxis, lachrymation, salivation, swelling of the tongue (gum); unpleasant taste (loz); cough, rhinitis, stomatitis, sinusitis, dry mouth (inhalator); ear sensations (nasal spray); skin reactions (patch).

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 w/ water w/o using soap and dried.
Drug Interactions
May enhance the haemodynamic effects of adenosine. Decreased metabolism leading to increased plasma concentrations w/ methoxsalen.
Food Interaction
Acidic beverages (e.g. coffee, juices, carbonated soft drinks) may inhibit buccal absorption of nicotine.
Action
Nicotine, 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.
Absorption: Readily absorbed through mucous membranes and the skin. Time to peak plasma concentration: 4-15 min (intranasal); 15-30 min (oral inhalation); 25-30 min (gum); 2-10 hr (TTS).
Distribution: Widely distributed into most body tissues and fluids. Crosses blood-brain barrier and placenta; enters breast milk. Volume of distribution: Approx 2-3 L/kg. Plasma protein binding: 5-20%.
Metabolism: Metabolised mainly in the liver via CYP2A6 isoenzyme into cotinine and nicotine-N-oxide. Undergoes extensive first-pass metabolism.
Excretion: Via urine (approx 10-20% as unchanged drug). Elimination half-life: 1-2 hr (intranasal and oral inhalation); approx 4 hr (TTS).
