Descarboethoxyloratadine
Descarboethoxyloratadine Uses, Dosage, Side Effects, Food Interaction and all others data.
Descarboethoxyloratadine is a long-acting, tricyclic, non-sedating, selective peripheral histamine H1-receptor antagonist which inhibits the release of pro-inflammatory mediators from human mast cells and basophils.
Descarboethoxyloratadine is a long-acting second-generation H1-receptor antagonist which has a selective and peripheral H1-antagonist action. Histamine is a chemical that causes many of the signs that are part of allergic reactions, such as the swelling of tissues. Histamine is released from histamine-storing cells (mast cells) and attaches to other cells that have receptors for histamine. The attachment of the histamine to the receptors causes the cell to be "activated," releasing other chemicals which produce the effects that we associate with allergies. Descarboethoxyloratadine blocks one type of receptor for histamine (the H1 receptor) and thus prevents activation of cells by histamine. Unlike most other antihistamines, Descarboethoxyloratadine does not enter the brain from the blood and, therefore, does not cause drowsiness.

Uses
Allergic Rhinitis: Descarboethoxyloratadine is used for the relief of the nasal and non-nasal symptoms of allergic rhinitis (Both seasonal and perennial) in patients 2 years of age and older.
Chronic Idiopathic Urticaria: Descarboethoxyloratadine is also used for the symptomatic relief of pruritus, reduction in the number of hives, and size of hives, in patients with chronic idiopathic urticaria 2 years of age and older.
Descarboethoxyloratadine is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Asthma, Chronic Idiopathic Urticaria, Common Cold, Nasal Congestion, Perennial Allergic Rhinitis (PAR), Seasonal Allergic Rhinitis, Nasal symptoms, Non-nasal symptoms, Antihistamine
How Descarboethoxyloratadine works
Like other H1-blockers, Descarboethoxyloratadine competes with free histamine for binding at H1-receptors in the GI tract, uterus, large blood vessels, and bronchial smooth muscle. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms (eg. nasal congestion, watery eyes) brought on by histamine.

Side Effects
Descarboethoxyloratadine is generally well tolerated. However, dry mouth, fatigue, somnolence and myalgia are commonly reported side-effects. Less common side-effects may include dizziness, headache and nausea. Rarely rash, pruritus and urticaria may occur.
Toxicity
Information regarding desloratadine overdose is limited, although somnolence has been reported. In case of overdose, symptomatic and supportive treatment, including removing the unabsorbed drug, is recommended; note, however, that desloratadine and its active metabolite 3-hydroxydesloratadine cannot be eliminated by hemodialysis.
In animal studies, lethality was observed at or above doses of 250 mg/kg in rats and of 353 mg/kg in mice (oral LD50), doses that represent 120 and 290 times the human exposure based on the recommended daily oral dose. In monkey, no deaths occurred at doses up to 250 mg/kg, representing an exposure roughly 810 times that of the recommended dose in humans.
Precaution
Hepatic and renal impairment. Pregnancy and lactation.
Interaction
Concomitant administration of Erythromycin, Ketoconazole, Azithromycin, Fluoxetine, and Cimetidine with Descarboethoxyloratadine increased the plasma concentration of Descarboethoxyloratadine. But there were no clinically relevant changes in the safety profile of Descarboethoxyloratadine.
Food Interaction
- Take with or without food. The absorption is unaffected by food.
Descarboethoxyloratadine Disease Interaction
Elimination Route
Descarboethoxyloratadine administered orally for ten days to healthy volunteers as a 5 mg tablet once daily resulted in a mean Tmax of approximately 3 hours, a mean steady-state Cmax of 4 ng/ml, and a mean steady-state AUC of 56.9 ng*hr/ml. A similar profile was observed using 10 ml of an oral solution containing 5 mg of desloratadine. Food was found not to affect desloratadine absorption.
Half Life
Descarboethoxyloratadine has a mean plasma elimination half-life of approximately 27 hours.
Elimination Route
Approximately 87% of a C-desloratadine dose was equally recovered in urine and feces as metabolic products.
Pregnancy & Breastfeeding use
Pregnancy: There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, Descarboethoxyloratadine should be used in pregnancy only if clearly needed.
Lactation: Descarboethoxyloratadine passes into breast milk. Therefore, a decision should be made whether to discontinue nursing or to discontinue Descarboethoxyloratadine, taking into account the importance of the drug to the mother.
Contraindication
Descarboethoxyloratadine is contraindicated in patient having hypersensitivity to this medication or to any of its ingredients or Loratadine.
Special Warning
Paediatric Use: The safety and effectiveness of Descarboethoxyloratadine in pediatric patients under 2 years of age have not been established.
Geriatric Use: In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
In adult patients with liver or renal impairment: A starting dose of one 5 mg tablet every other day is recommended based on pharmacokinetic data.
Acute Overdose
No clinically relevant adverse events have been reported in case of overdosage. However, in the event of overdosage, symptomatic and supportive treatment is recommended.
Storage Condition
Store in a cool and dry place, protected from light.
