Lixacol
Lixacol Uses, Dosage, Side Effects, Food Interaction and all others data.
Although the mechanism of action of mesalazine is not fully understood, it appears to be topical rather than systemic. Mucosal production of arachidonic acid metabolites, both through the cyclooxygenase pathways, i.e., prostanoids, and through the lipoxygenase pathways, i.e., leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with chronic inflammatory bowel disease, and it is possible that mesalazine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon.
Lixacol is one of the two components of sulphasalazine, the other being sulphapyridine. It is the latter which is responsible for the majority of the side effects associated with sulphasalazine therapy whilst mesalazine is known to be the active moiety in the treatment of ulcerative colitis .
The pharmacodynamic actions of mesalazine occur in the colonic/rectal mucosae local to the delivery of drug from mesalazine tablets into the lumen . There is information suggesting that the severity of colonic inflammation in ulcerative colitis patients treated with mesalazine is inversely correlated with mucosal concentrations of mesalazine . Plasma concentrations representing systemically absorbed mesalazine are not believed to contribute extensively to efficacy .

Uses
This medication is used to treat a certain bowel disease (ulcerative colitis). It helps to reduce symptoms of ulcerative colitis such as diarrhea, rectal bleeding, and stomach pain. Mesalamine belongs to a class of drugs known as aminosalicylates.This medication may also be used to treat Crohn's disease.
Lixacol is also used to associated treatment for these conditions: Crohn's Disease (CD), Proctitis, Ulcerative, Proctosigmoiditis, Ulcerative Colitis
How Lixacol works
Although the mechanism of action of mesalazine is not fully understood, it is believed to possess a topical anti-inflammatory effect on colonic epithelial cells . Mucosal production of arachidonic acid metabolites, both through the cyclooxygenase pathways, i.e., prostanoids, and through the lipoxygenase pathways, i.e., leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with chronic inflammatory bowel disease, and it is possible that mesalazine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon .
Furthermore, mesalazine also has the potential to inhibit the activation of Nuclear Factor kappa B (NKkB) and consequently the production of key of pro-inflammatory cytokines . It has been proposed that reduced expression of PPAR gamma nuclear receptors (gamma form of peroxisome proliferator-activated receptors) may be implicated in ulcerative colitis . There is evidence that mesalazine produces pharmacodynamic effects through direct activation of PPAR gamma receptors in the colonic/rectal epithelium as well .
Moreover, since increased leukocyte migration, abnormal cytokine production, increased production of arachidonic acid metabolites, particularly leukotriene B4, and increased free radical formation in the inflamed intestinal tissue are all present in patients with inflammatory bowel disease it is also believed that mesalazine has in-vitro and in-vivo pharmacological effects that inhibit leukocyte chemotaxis, decrease cytokine and leukotriene production and scavenge for free radicals .

There have been no documented reports of serious toxicity in man resulting from massive overdosing with mesalamine. Under ordinary circumstances, mesalazine absorption from the colon is limited. Although there is little to no clinical experience with mesalazine overdosage . Lixacol is an aminosalicylate, and symptoms of salicylate toxicity may be possible, such as tinnitus, vertigo, headache, confusion, drowsiness, sweating, hyperventilation, vomiting, and diarrhea . Severe intoxication with salicylates can lead to disruption of electrolyte balance and blood-pH, hyperthermia, and dehydration .
Precaution
Use with caution, usually starting at the low end of the dosage range, because of the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant diseases or other drug therapy.
Hypersensitivity: Some patients who have experienced a hypersensitivity reaction to sulfasalazine may have a similar reaction to mesalamine.
Renal Function: Patients with history of renal function impairment or disease may have worsening of renal function.
Hepatic Function: Use with caution. There have been reports of hepatic failure in patients with preexisting liver disease.
Sulfite Sensitivity: Some products may contain sulfites, which may cause allergic reactions in susceptible individuals.
Interaction
Antacids: Because the dissolution of the coating of Apriso granules depends on pH, do not administer with antacids.
Nephrotoxic agents (including NSAIDs): Increased risk of renal adverse reactions.
Thiopurines (eg, azathioprine, mercaptopurine): Risk of leukopenia may be increased.
Warfarin: Decreased anticoagulant effect of warfarin has been reported in 1 patient.
Laboratory Test Interactions: None well documented.
Food Interaction
- Take with or without food. The absorption is unaffected by food.
Volume of Distribution
The apparent volume of distribution (Vd) of the drug in adults is approximately 0.2 L/kg .
Elimination Route
Depending on the formulation administered, prescribing information for orally administered delayed-released tablets of 2.4g or 4.8g of mesalazine given once daily for 14 days to healthy volunteers was to found to be about 21% to 22% of the administered dose while prescribing information for an orally administered controlled-release capsule formulation suggests 20% to 30% of the mesalazine in the formulation is absorbed . In contrast, when mesalamine is administered orally as an unformulated 1-g aqueous suspension, mesalazine is approximately 80% absorbed .
Half Life
The apparent elimination half-life documented for oral delayed-release mesalazine tablets is 7 to 12 hours . The elimination half-life recorded for the active N-acetyl-5-aminosalicylic acid metabolite generated from the administration of oral delayed-release mesalazine tablets is 12 to 23 hours .
Clearance
The mean (SD) renal clearance in L/h for mesalazine following the single dose administration of mesalazine delayed-release tablets 4.8g under fasting conditions to young and elderly subjects was documented as 2.05 (1.33) in young subjects aged 18 to 35 years old, 2.04 (1.16) in elderly subjects aged 65 to 75 years old, and 2.13 (1.20) in elderly subjects older than 75 years .
Elimination Route
Elimination of mesalazine is mainly via the renal route following metabolism to N-acetyl-5-aminosalicylic acid (acetylation) . However, there is also limited excretion of the parent mesalazine drug in the urine .
After the oral administration of the extended-release formulation of mesalazine, of the approximately 21% to 22% of the drug absorbed, less than 8% of the dose was excreted unchanged in the urine after 24 hours, compared with greater than 13% for N-acetyl-5-aminosalicylic acid .
When given the controlled-release formulation, about 130 mg free mesalazine was recovered in the feces following a single 1-g dose, which was comparable to the 140 mg of mesalazine recovered from the molar equivalent sulfasalazine tablet dose of 2.5 g F3001]. Elimination of free mesalazine and salicylates in feces increased proportionately with the dose given. N-acetylmesalazine was the primary compound excreted in the urine (19% to 30%) following the controlled-release dosing .
