Kestine

Ebastine, the active ingredient in Kestine, is a second‑generation H1 antihistamine presented as a unknown strength/unknown form for oral use. It treats allergic rhinitis and chronic idiopathic urticaria in adults and adolescents, providing relief from nasal congestion, sneezing, itching and hives.

GNH USA supplies Kestine as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies, clinics and other healthcare institutions worldwide, ensuring quality and regulatory compliance across all markets.

Kestine (ebastine) is used to manage allergic conditions that involve histamine‑mediated responses.

Allergic rhinitis: reduces nasal congestion, sneezing, itching and rhinorrhea. Seasonal allergic rhinitis (hay fever): alleviates symptoms triggered by seasonal allergens. Chronic idiopathic urticaria: decreases the frequency and severity of hives and associated itching.

Common Side Effects: - Headache: mild to moderate intensity. - Dry mouth: transient sensation of oral dryness. - Drowsiness: occasional mild sedation. - Fatigue: feeling of reduced energy. - Nausea: occasional upset stomach.

Serious or Rare Side Effects: - Cardiac arrhythmia: irregular heart rhythm, requires medical attention. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Anaphylaxis: rapid onset of systemic allergic reaction. - Hepatotoxicity: signs of liver injury, e.g., jaundice or elevated enzymes. - Hematologic abnormalities: rare blood cell count changes.

Before initiating therapy, consider the following precautions.

Pregnancy: Category B; use only if clearly needed after risk‑benefit assessment. Breastfeeding: Caution; monitor infant for possible effects. Elderly: May require dose adjustment due to altered pharmacokinetics. Renal or hepatic impairment: Use with caution; monitor clinical response. Drug interactions: Review concomitant medications for potential interactions. Store at ambient temperature: keep below 25°C, retain in original packaging, protect from moisture and direct sunlight.

Ebastine may interact with several medicines; monitor accordingly.

Major Interactions (Avoid): - Ketoconazole: can markedly increase ebastine plasma concentrations. - Ritonavir: potent CYP3A4 inhibitor that raises ebastine levels. - Cimetidine: may elevate ebastine exposure.

Moderate Interactions (Monitor Closely): - Other azole antifungals (e.g., itraconazole): may increase levels modestly. - Macrolide antibiotics (e.g., erythromycin): may require observation for enhanced effects.
