Niconic50 mg

Niconic is a form of vitamin B3 used for two distinct purposes depending on the dose:

• Niacin deficiency and pellagra (established use): prevention and treatment of dietary niacin deficiency, including pellagra (characterized by dermatitis, diarrhea, and dementia), at nutritional/vitamin-range doses.
• Dyslipidemia (adjunct therapy) (established, prescription use): at pharmacologic doses, Niconic is used as an adjunct to diet, and often in combination with other lipid-lowering agents, to reduce elevated LDL-cholesterol and triglycerides and raise HDL-cholesterol in patients with primary hyperlipidemia or mixed dyslipidemia, including reducing the risk of pancreatitis in patients with very high triglycerides.

Use of Niconic specifically for cardiovascular event reduction has declined in recent years because large outcome trials did not show additional cardiovascular benefit when Niconic was added to statin therapy, and better-tolerated lipid-lowering options are now generally preferred; a physician should decide whether Niconic is appropriate for a given patient.

Each tablet of Nicotinic Acid [Niacin] contains Nicotinic Acid (Niacin) INN as the active ingredient, commonly available as immediate-release tablets (e.g., 50 mg, 100 mg, 250 mg, 500 mg) and, in some markets, extended/sustained-release tablets (e.g., 500 mg, 750 mg, 1000 mg). Strength and release type available may vary by manufacturer; the exact formulation of Nicotinic Acid [Niacin] should be confirmed on the product label.

Niconic is a water-soluble B-complex vitamin (vitamin B3) that the body needs to convert food into energy and to maintain healthy skin, nerves, and digestion. At doses well above nutritional requirements, Niconic also has a distinct pharmacologic effect on lipid metabolism, lowering LDL-cholesterol and triglycerides while raising HDL-cholesterol, which is why it is also used as a prescription lipid-lowering agent in addition to being used as a vitamin supplement.

Niconic belongs to the vitamin B-complex group (water-soluble vitamins) and, at pharmacologic doses, also belongs to the antihyperlipidemic (lipid-modifying) agents class.

As a vitamin, Nicotinic Acid [Niacin] is a precursor of nicotinamide adenine dinucleotide (NAD) and its phosphate (NADP), coenzymes essential for tissue respiration, glycogenolysis, and lipid metabolism.

At pharmacologic (much higher than nutritional) doses, Nicotinic Acid [Niacin] reduces hepatic synthesis of very-low-density lipoprotein (VLDL) by inhibiting lipolysis in adipose tissue via the GPR109A receptor, which decreases free fatty acid flux to the liver, and by directly inhibiting hepatic diacylglycerol acyltransferase-2. Reduced VLDL synthesis lowers downstream LDL-cholesterol and triglycerides, while Nicotinic Acid [Niacin] separately increases HDL-cholesterol by reducing the hepatic clearance of apolipoprotein A-I.

Niconic is taken by mouth. To reduce flushing, it is often taken with food (avoiding hot beverages and alcohol around dosing time) and sometimes with a physician-directed dose of aspirin or another NSAID taken 30 minutes beforehand. Extended-release tablets of Niconic should be swallowed whole (not crushed or chewed) and are typically taken at bedtime. Dosing should be uptitrated gradually as directed, and doses should not be doubled if one is missed.

Niconic has clinically significant interactions with:

• Statins (HMG-CoA reductase inhibitors): combined use with Niconic increases the risk of myopathy and rhabdomyolysis; the combination requires careful monitoring.
• Bile acid sequestrants (e.g., cholestyramine, colestipol): can reduce absorption of Niconic; doses should be separated by at least 4–6 hours.
• Antihypertensive agents/vasodilators: additive risk of hypotension, especially early in Niconic therapy due to flushing-related vasodilation.
• Alcohol: may increase flushing and the risk of hepatotoxicity when taken with Niconic.
• Anticoagulants (e.g., warfarin): high-dose Niconic can prolong prothrombin time; monitor patients closely.

Common side effects of Niconic:

• Flushing, warmth, itching, and tingling of the skin (very common, especially with immediate-release formulations; usually dose-related and diminishes over time).
• Gastrointestinal upset (nausea, vomiting, dyspepsia, diarrhea).
• Headache.

Less common but clinically important effects of Niconic:

• Hepatotoxicity, including elevated liver enzymes (risk is higher with sustained-release formulations at high doses).
• Hyperglycemia (may worsen glycemic control in diabetes).
• Hyperuricemia, which may precipitate gout.
• Myopathy, particularly when combined with statins (see Interactions).
• Hypotension.

At nutritional/dietary-supplement doses, Niconic is considered safe in pregnancy and breastfeeding, as niacin is an essential nutrient required in normal amounts. At pharmacologic (prescription lipid-lowering) doses, however, Niconic should be used during pregnancy only if clearly needed and if the potential benefit justifies the potential risk to the fetus, since dyslipidemia treatment is not usually a priority during pregnancy and safety data at high doses are limited. It is not established whether pharmacologic doses of Niconic pass into breast milk in clinically significant amounts; a physician should be consulted before use of pharmacologic-dose Niconic during breastfeeding.

Niconic should be used with caution and under medical supervision, with attention to:

• Liver function: periodic liver function tests are recommended during Niconic therapy, particularly with higher doses or sustained-release formulations, given the risk of hepatotoxicity (see Contraindications for active liver disease).
• Diabetes mellitus: Niconic may raise blood glucose; glucose monitoring is advised.
• Gout or hyperuricemia: use Niconic with caution as it can raise uric acid levels.
• History of peptic ulcer disease (inactive): use Niconic with caution, as it can cause GI irritation.
• Hypotension or use with antihypertensives: flushing-related vasodilation from Niconic may cause or worsen low blood pressure, particularly on standing.
• Concurrent statin use: increased risk of myopathy/rhabdomyolysis (see Interactions).

Flushing is common with Niconic, especially at the start of therapy or after a dose increase; taking Niconic with food, avoiding alcohol and hot beverages around dosing time, and physician-directed pretreatment with aspirin may reduce flushing.

Overdose with Niconic may cause pronounced flushing, hypotension, dizziness, gastrointestinal upset, and, in severe or prolonged high-dose use, liver injury. If an overdose of Niconic is suspected, seek immediate medical attention or contact a poison control center; treatment is supportive and should be provided by a healthcare professional.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.

Pediatric use: Niconic may be used to treat documented niacin deficiency in children under medical supervision with age/weight-appropriate dosing. Safety and efficacy of pharmacologic (lipid-lowering) doses of Niconic have not been well established in children, and it is not generally recommended for pediatric dyslipidemia outside specialist guidance.

Elderly: No specific dose adjustment of Niconic is established for elderly patients, but they may be more susceptible to flushing, hypotension, and hepatotoxicity; use the lowest effective dose of Niconic with close monitoring.

Renal impairment: Use pharmacologic doses of Niconic with caution; specific dose adjustments are not well established, and clinical monitoring is advised.

Hepatic impairment: Niconic is contraindicated in significant/active hepatic disease (see Contraindications).

For niacin deficiency, Niconic is typically continued until symptoms resolve and adequate nutritional status is restored, usually a few weeks. For dyslipidemia, Niconic is generally used long-term as part of ongoing lipid management, with periodic physician review of lipid levels, liver function, and tolerability to determine whether continued treatment with Niconic is appropriate.

Vitamin B-complex (water-soluble vitamin); Antihyperlipidemic / lipid-modifying agent. Nicotinic Acid [Niacin] belongs to both classes depending on the dose used.

As a vitamin, Nicotinic Acid [Niacin] is converted in the body to NAD and NADP, coenzymes required for cellular energy metabolism. At pharmacologic doses, Nicotinic Acid [Niacin] activates the GPR109A receptor on adipocytes, inhibiting lipolysis and reducing free fatty acid delivery to the liver; this, together with direct inhibition of hepatic diacylglycerol acyltransferase-2, decreases hepatic VLDL and, consequently, LDL-cholesterol and triglyceride production, while also increasing HDL-cholesterol by slowing its hepatic clearance.

C (at pharmacologic/prescription lipid-lowering doses); nutritional/RDA-level doses are considered Category A

Niconic may be used under medical supervision to treat confirmed niacin deficiency in children at age/weight-appropriate doses. However, safety and efficacy of pharmacologic (high-dose, lipid-lowering) Niconic therapy have not been established in pediatric patients, and such use is not generally recommended outside specialist care.
