What NCX 470 is used for

NCX 470 is an investigational medicine that is currently in late-stage development. It is being studied for its potential use in treating:

• Open-angle glaucoma: This is a common eye condition where the pressure inside your eye (intraocular pressure) slowly increases. If left untreated, this increased pressure can damage the optic nerve, which connects your eye to your brain. This damage can lead to permanent vision loss. NCX 470 is being developed to help manage this condition by reducing eye pressure.

Please remember that NCX 470 is not yet approved or routinely available in India. This information is provided for educational purposes only. Always consult your ophthalmologist about approved and available treatment options for your specific condition.

How it works

NCX 470 is a unique type of medicine known as a NO-donating prostaglandin analogue. This means it works in a dual way to help reduce the pressure inside your eye:

• Prostaglandin analogue action: Like other prostaglandin analogues, it is believed to increase the outflow of fluid from your eye, thereby lowering the intraocular pressure.
• NO-donating action: It also releases nitric oxide (NO) within the eye. Nitric oxide is known to have properties that can further help in reducing eye pressure by relaxing certain tissues and improving fluid drainage.

This dual mechanism of action is being investigated to see if it can provide an effective way to manage open-angle glaucoma.

How it’s used

As NCX 470 is still under study and not yet approved, the exact dosing instructions are still being determined. However, as an eye drop medicine, it would typically be administered directly into the affected eye(s) as prescribed by an ophthalmologist.

When this medicine becomes available and approved, your ophthalmologist will provide you with precise instructions on how often and how much to use. It is crucial to follow these instructions exactly to ensure the medicine works effectively and safely. Do not change your dose or stop using the medicine without consulting your doctor.

Always follow your ophthalmologist’s exact instructions.

Precautions & side effects

NCX 470 is currently in late-stage development, meaning it is still undergoing rigorous testing and evaluation. Therefore, specific precautions and a full safety profile are still being established. However, as with any eye medicine, general precautions apply:

• Prescription Medicine: NCX 470 is an investigational prescription eye medicine. It must only be used as directed by a qualified ophthalmologist.
• Professional Medical Advice: This page provides general education and is not a substitute for professional medical advice, diagnosis, or a prescription.
• No Self-Medication: Do not self-medicate or reuse an old prescription. Always get a fresh prescription and guidance from your doctor.
• Not Approved in India: NCX 470 is not currently approved or routinely available in India. This information is included for reference. Please ask your ophthalmologist about approved alternatives that are available.
• Hygiene: Always wash your hands thoroughly before applying eye drops to prevent contamination.
• Contact Lenses: If you wear contact lenses, your doctor will advise you on whether you need to remove them before applying the drops and how long to wait before reinserting them.
• Storage: Store the medicine as directed, typically in a cool, dry place, away from direct sunlight and out of reach of children.
• Reporting Side Effects: If you experience any unusual or bothersome symptoms after using eye drops, inform your ophthalmologist immediately.

Your ophthalmologist is the best person to advise you on the suitability of any treatment and to discuss any potential risks or side effects.

Understanding Open-Angle Glaucoma

Open-angle glaucoma is a serious eye condition that can lead to irreversible vision loss if not managed properly. It’s often called the ‘silent thief of sight’ because it usually has no noticeable symptoms in its early stages. In this condition, the drainage system of your eye, known as the ‘angle,’ remains open, but the fluid inside your eye (aqueous humour) doesn’t drain as efficiently as it should. This leads to a gradual build-up of pressure inside your eye, called intraocular pressure (IOP).

Over time, this increased pressure can damage the optic nerve, which is like the cable connecting your eye to your brain, transmitting visual information. Once the optic nerve is damaged, the vision loss is permanent. Regular eye check-ups, especially if you are over 40, have a family history of glaucoma, or have other risk factors like diabetes or high blood pressure, are crucial for early detection. Early diagnosis and treatment can help preserve your vision.

Correctly Using Eye Drops: A Step-by-Step Guide

Using eye drops correctly is vital for them to work effectively and to prevent infection. Here’s a simple guide:

1. Wash Your Hands: Always start by thoroughly washing your hands with soap and water. This prevents germs from entering your eye.
2. Prepare the Bottle: If the bottle is new, check the seal. If it’s a suspension, shake it gently as instructed by your doctor or pharmacist.
3. Position Yourself: Tilt your head back or lie down. Gently pull down your lower eyelid with one finger to create a small pocket.
4. Administer the Drop: Hold the dropper bottle upside down with your other hand, directly over your eye. Try not to touch your eye or eyelashes with the tip of the dropper to avoid contamination. Squeeze the bottle gently to release one drop into the pocket you created.
5. Close Your Eye: Gently close your eye for a minute or two. Avoid blinking excessively or squeezing your eyes shut, as this can push the medicine out.
6. Apply Pressure (Optional but Recommended): Gently press your finger against the inner corner of your eye, near your nose, for about a minute. This helps prevent the medicine from draining into your tear duct and entering your bloodstream, allowing more of it to stay in your eye.
7. Wipe Excess: Gently blot any excess liquid around your eye with a clean tissue.
8. Wash Hands Again: Wash your hands again to remove any medicine.

If you need to use more than one type of eye drop, wait at least 5-10 minutes between different drops to allow each medicine to be absorbed properly.

General Eye Care, Hygiene, and When to Seek Help

Maintaining good eye hygiene and knowing when to seek professional help are important for overall eye health, especially when managing conditions like glaucoma. Always store your eye drops as directed on the packaging, usually in a cool, dry place, away from direct sunlight and out of reach of children. Never share your eye drops with anyone else, even if they have similar symptoms, as this can spread infection or be harmful. Always check the expiry date on the bottle and discard any expired medicine.

If you experience any new or worsening symptoms, such as persistent eye pain, redness, blurred vision, discharge from the eye, or a sudden decrease in vision, contact your ophthalmologist immediately. These could be signs of an infection, an allergic reaction, or a worsening of your underlying condition. Regular follow-up appointments with your ophthalmologist are crucial to monitor your eye pressure and the health of your optic nerve, ensuring your treatment plan remains effective. Remember, your ophthalmologist is your best resource for managing your eye health and addressing any concerns you may have.
