Histafree Raspberry Vani Flav
Histafree Raspberry Vani Flav Uses, Dosage, Side Effects, Food Interaction and all others data.
Histafree Raspberry Vani Flav Hydrochloride is an antihistamine with selective peripheral H1 receptor antagonist activity. It inhibits histamine release from peritoneal mast cells. No anticholinergic, α-1 adrenergic or β-adrenergic receptor blocking effects has been observed. No sedative or other central nervous system effect has been observed. It does not appear to cross the blood brain barrier.
Histafree Raspberry Vani Flav is rapidly absorbed after oral administration with peak plasma concentration being reached in 2-3 hours. Elimination half-life of about 14 hours has been reported although this may be prolonged in patients with renal impairment.
Histafree Raspberry Vani Flav relieves allergy symptoms by antagonizing the actions of histamine, an endogenous compound predominantly responsible for allergic symptomatology. The relatively long duration of action of fexofenadine (approximately 24 hours) allows for once or twice daily dosing, and its rapid absorption allows for an onset of action within 1-3 hours. Histafree Raspberry Vani Flav should not be taken with fruit juice, as this may impair its absorption.

Uses
It is used for the relief of symptoms associated with seasonal and perennial allergic rhinitis and chronic idiopathic urticaria.
Histafree Raspberry Vani Flav is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Chronic Idiopathic Urticaria, Seasonal Allergic Rhinitis, Antihistamine
How Histafree Raspberry Vani Flav works
The H1 histamine receptor is responsible for mediating hypersensitivity and allergic reactions. Exposure to an allergen results in degranulation of mast cells and basophils, which then release histamine and other inflammatory mediators. Histamine binds to, and activates, H1 receptors, which results in the further release of pro-inflammatory cytokines, such as interleukins, from basophils and mast cells. These downstream effects of histamine binding are responsible for a wide variety of allergic symptoms, such as pruritus, rhinorrhea, and watery eyes.
Histafree Raspberry Vani Flav is considered an “inverse agonist” of the H1 receptor because it binds to and stabilizes the inactive form of the receptor, preventing its activation and subsequent downstream effects. It has a potent and selective affinity for H1 receptors, and there is no evidence that it carries antidopaminergic, antiserotonergic, anticholinergic, sedative, or adrenergic blocking activity. Histafree Raspberry Vani Flav does not cross the blood-brain barrier and thus is unlikely to cause significant CNS effects.
Dosage
Histafree Raspberry Vani Flav dosage
Adults-
- Allergic rhinitis: 120 mg once daily or 60 mg twice daily
- Urticaria: 180 mg once daily
Children-
- 2-11 years: 30 mg (1 spoonful) or 5 ml twice daily
- 6 months-2 years: 15 mg (1/2 spoonful) or 2.5 ml twice daily
In case of decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function.
Side Effects
Histafree Raspberry Vani Flav is generally well tolerated. The most commonly reported adverse events are headache, drowsiness, nausea, and dizziness. The incidence of these events observed with Histafree Raspberry Vani Flav hydrochloride was similar to that observed with placebo.
Toxicity
No deaths were observed following the oral administration of up to 5000 mg/kg in both mice and rats (equivalent to approximately 100-200x the recommended human dose). Single doses of up to 800 mg and chronic exposure of up to 690 mg twice daily for 1 month in humans did not result in clinically significant adverse events. Symptoms of overdosage are consistent with fexofenadine's adverse effect profile and are likely to include dizziness, drowsiness, and dry mouth.
If overdosage occurs, employ symptomatic and supportive treatment. Hemodialysis does not effectively remove fexofenadine from the blood and is therefore of no benefit.
Precaution
Studies in the elderly, patients with hepatic impairment and patients with cardiac disease exposed to Histafree Raspberry Vani Flav showed no statistically significant differences compared to healthy individuals. As with most new drugs there is only limited data in the elderly and renally or hepatically impaired patients. Histafree Raspberry Vani Flav hydrochloride should be administered with care in these special groups.
Interaction
Co-administration of Histafree Raspberry Vani Flav Hydrochloride with either ketoconazole or erythromycin may cause increased plasma concentration of Histafree Raspberry Vani Flav. Antacid containing Aluminium and Magnesium may reduce the absorption of Histafree Raspberry Vani Flav. Fruit juices such as grapefruit, orange and apple may reduce the bioavailability of Histafree Raspberry Vani Flav.
Food Interaction
- Avoid fruit juice. Fruit juices like grapefruit, orange, and apple may reduce bioavailability and overall exposure to the medication.
- Take with or without food. Co-administration with food does not significantly affect absorption.
[Moderate] GENERALLY AVOID: Coadministration with large amounts of certain fruit juices, including grapefruit, orange and apple, may decrease the oral bioavailability of fexofenadine.
The proposed mechanism is inhibition of drug efflux via intestinal organic anion transporting polypeptides (e.g., P-glycoprotein), of which fexofenadine is a substrate.
In a five-way crossover study with 10 healthy volunteers, 1<4-strength grapefruit juice, grapefruit juice, orange juice and apple juice (300 mL with drug administration and 150 mL every 1<2 hour for up to 3 hours, total volume 1.2 L) reduced the mean area under the plasma concentration-time curve (AUC) of a 120 mg dose of fexofenadine by 23%, 67%, 72% and 77%, respectively, compared to water.
Mean peak plasma concentration (Cmax) was similarly affected.
The clinical significance of these changes is unknown.
However, results from studies using histamine-induced skin wheals and flares found that the size of wheal and flare was significantly larger when fexofenadine was administered with either grapefruit or orange juices compared to water.
MANAGEMENT: To maximize plasma levels and therapeutic effects, fexofenadine should be taken with water.
In addition, patients should refrain from consuming large amounts of grapefruit, orange, or apple juice.

Histafree Raspberry Vani Flav Disease Interaction
Volume of Distribution
The volume of distribution is approximately 5.4-5.8 L/kg.
Elimination Route
Histafree Raspberry Vani Flav is rapidly absorbed following oral administration and its absolute bioavailability is approximately 33%. The Tmax following oral administration is approximately 1-3 hours. The steady-state AUCss(0-12h) and Cmax following twice daily dosing of 60mg are 1367 ng/mL.h and 299 ng/mL, respectively.
Histafree Raspberry Vani Flav AUC is decreased by >20% when coadministered with fruit juices (e.g. apple, orange, grapefruit) due to their inhibition of OATP transporters - for this reason, prescribing information recommends administering fexofenadine only with water. Similarly, coadministration of fexofenadine with a high-fat meal appears to decrease AUC and Cmax by >20%.
Half Life
The terminal elimination half-life is approximately 11-15 hours.
Clearance
The oral clearance of fexofenadine is approximately 50.6 L/h and the renal clearance is approximately 4.32 L/h.
Elimination Route
Approximately 80% of an ingested dose is eliminated in the feces, likely largely unchanged due to fexofenadine's limited metabolism, and 11% is eliminated in the urine. The principal pathways of fexofenadine elimination are biliary and renal.
Pregnancy & Breastfeeding use
Pregnancy Category B. There are no adequate and well controlled studies in pregnant women. Histafree Raspberry Vani Flav should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation: It is not known if Histafree Raspberry Vani Flav is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Histafree Raspberry Vani Flav is administered to a nursing woman.
Contraindication
Histafree Raspberry Vani Flav is contraindicated in patients with known hypersensitivity to Histafree Raspberry Vani Flav or any of the ingredients of Histafree Raspberry Vani Flav Hydrochloride.
