The Efficacy of Local Application of B-sitosterol Versus Vasline in Cases of Idiopathic Epistaxis
A Phase 4 study testing vasline and B-sitosterol in people with Epistaxis, run by Assiut University.
Trial summary
Epistaxis, commonly known as nosebleed, is a frequent otorhinolaryngological complaint, affecting a large proportion of the population. Approximately 60% of individuals experience at least one episode during their lifetime, while around 6% require medical intervention'. Read more about this study

About this study
Epistaxis, commonly known as nosebleed, is a frequent otorhinolaryngological complaint, affecting a large proportion of the population. Approximately 60% of individuals experience at least one episode during their lifetime, while around 6% require medical intervention'. The majority of cases are anterior in origin, arising from Kiesselbach's plexus in the anterior nasal septum(2) Idiopathic epistaxis refers to recurrent nasal bleeding without any identifiable local or systemic cause. (3) Factors such as mucosal dryness, minor trauma, inflammation, and environmental conditions can predispose the nasal mucosa to bleeding(4) Maintaining mucosal integrity and hydration is essential in preventing recurrence.
Conservative management remains the first-line treatment for anterior epistaxis. Strategies include direct nasal compression, topical vasoconstrictors, nasal packing, and application of moisturizing agents(5) Petroleum jelly (Vaseline) is widely used as a topical agent to maintain hydration, protect the mucosa, and reduce crust formation, thereby minimizing the risk of further bleeding(6) B-sitosterol, a plant-derived phytosterol, has shown anti-inflammatory, immunomodulatory, and tissue-healing properties in several experimental and clinical studies'(7,8) Its anti-inflammatory activity may stabilize the nasal mucosa and enhance repair processes, suggesting a potential therapeutic rol in conditions like idiopathic epistaxis(9) Previous studies hav demonstrated B-sitosterol's efficacy in reducing mucosal inflammation and promoting healing in other mucosal tissues, although its use in ENT applications remains underexplored'(7,8) Considering these properties, B-sitosterol may represent a promising topical alternative to conventional moisturizers such as Vaseline for managing idiopathic epistaxis. This study aims to evaluate and compare the efficacy of local B-sitosterol versus Vaseline in reducing the frequency, duration, and severity of nosebleeds in affected patients.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing vasline and B-sitosterol in people with Epistaxis, run by Assiut University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 15 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
frequency of bleeding episodes (time frame: 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2026.
