What is Rexophtal N?

Rexophtal N (Rexophtal N) is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Rexophtal N is used to treat nasal and sinus congestion, or congestion of the tubes that drain fluid from your inner ears, called the eustachian (yoo-STAY-shun) tubes.

Rexophtal N may also be used for purposes not listed in this medication guide.

Rexophtal N indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Rexophtal N is used for the temporary relief of stuffy nose, sinus, and ear symptoms caused by the common cold, flu, allergies, or other breathing illnesses (e.g., sinusitis, bronchitis). This medication works by decreasing swelling in the nose and ears, thereby lessening discomfort and making it easier to breathe.

Cough-and-cold products have not been shown to be safe or effective in children younger than 6 years. Therefore, do not use this product to treat cold symptoms in children younger than 6 years unless specifically directed by the doctor. Some products (such as long-acting tablets/capsules) are not recommended for use in children younger than 12 years. Ask your doctor or pharmacist for more details about using your product safely.

How should I use Rexophtal N?

Use Rexophtal N drops as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Ask your health care provider any questions you may have about how to use Rexophtal N drops.

Uses of Rexophtal N in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Use: Labeled Indications

Hypotension/shock: Treatment of hypotension, vascular failure in shock. Note: Not recommended for routine use in the treatment of septic shock; use should be limited until more evidence demonstrating positive clinical outcomes becomes available (Rhodes 2017).

Guideline recommendations:

Cardiogenic shock: The 2017 American Heart Association (AHA) scientific statement for the Contemporary Management of Cardiogenic Shock recommends Rexophtal N, if needed, be considered for initial vasoactive management of cardiogenic shock due to aortic stenosis, mitral stenosis, or dynamic left ventricular outflow tract (LVOT) obstruction (AHA [van Diepen 2017]).

Hypotension during anesthesia: As a vasoconstrictor in regional analgesia

Nasal congestion: As a decongestant [OTC]

Off Label Uses

Hypotension in patients with obstructive hypertrophic cardiomyopathy

Rexophtal N is a pure alpha1 agonist that will increase systemic vascular resistance without increasing heart rate or contractility. This is advantageous in patients with obstructive hypertrophic cardiomyopathy and hypotension since increases in both heart rate and contractility may cause the obstruction to worsen, leading to a decrease in cardiac output. Other vasopressors like dopamine, epinephrine, and norepinephrine may increase contractility and/or heart rate. Additional trials may be necessary to further define the role of Rexophtal N in this condition.

Based on the American Urological Association guidelines for the management of priapism, due to the low risk of cardiovascular side effects intracavernous injection of Rexophtal N is recommended for ischemic priapism that persists following aspiration/irrigation.

Rexophtal N description

Rexophtal N is a sympathomimetic amine that acts predominantly on α-adrenergic receptors. It is mainly used to treat nasal congestion, but may also be useful in treating hypotension and shock, hypotension during spinal anaesthesia, prolongation of spinal anaesthesia, paroxysmal supraventricular tachycardia, symptomatic relief of external or internal hemorrhoids, and to increase blood pressure as an aid in the diagnosis of heart murmurs.
