Otrinazil (Xylometazoline Hydrochloride, Dexpanthenol)

Otrinazil, a nasal decongestant, acts on the upper‑respiratory tract to relieve congestion associated with several common conditions.

• Nasal congestion due to common cold: alleviates swelling of nasal mucosa and restores normal breathing.
• Sinusitis‑related nasal blockage: reduces mucosal edema, facilitating sinus drainage.
• Allergic rhinitis: diminishes nasal congestion caused by allergic inflammation.

• Xylometazoline Hydrochloride stimulates alpha‑adrenergic receptors on nasal mucosal blood vessels, causing vasoconstriction and reduced edema. Dexpanthenol is converted to pantothenic acid within mucosal cells, supporting tissue repair and forming a protective barrier that helps maintain mucosal integrity during irritation.

Adverse reactions may occur with intranasal use of Otrinazil. Most are mild and reversible.

Common Side Effects

• Nasal irritation: mild burning or stinging sensation.
• Sneezing: transient increase in sneezing episodes.
• Dryness of nasal mucosa: feeling of dryness or crusting.
• Headache: mild, short‑lasting headache.
• Taste disturbance: temporary alteration of taste perception.

Serious or Rare Side Effects

• Rebound congestion: worsening nasal blockage after prolonged use.
• Hypertension: elevated blood pressure in susceptible individuals.
• Cardiac arrhythmia: irregular heart rhythm in patients with underlying heart disease.
• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Nasal ulceration: rare ulcer formation in the nasal passages.

Before using Otrinazil, consider the following safety measures.

• Duration of use: limit to no more than 3‑5 consecutive days to avoid rebound congestion.
• Cardiovascular disease: avoid if you have uncontrolled hypertension or heart disease.
• Pregnancy and lactation: consult a healthcare professional before use.
• Children under 6 years: not recommended unless prescribed by a clinician.
• Drug interactions: inform your doctor of any concurrent nasal or systemic decongestants.
• Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight.

Otrinazil may interact with other medications that affect vascular tone or blood pressure. Major Interactions (Avoid):\n- Monoamine oxidase inhibitors (MAOIs): risk of excessive vasoconstriction.

• Systemic decongestants (e.g., pseudoephedrine): potential for severe hypertension.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may blunt the cardiovascular response.
• Antihypertensive agents: monitor blood pressure for additive effects.
• Anticholinergic drugs: possible increase in nasal dryness.
