Simbrinza Opthalmic (Brimonidine & Brinzolamide Ophthalmic)
What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Simbrinza Ophthalmic is a prescription medication used in the treatment of certain eye conditions. It is primarily prescribed to lower intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. Simbrinza Ophthalmic is a combination medication that contains two active ingredients: brinzolamide and brimonidine tartrate. Brinzolamide belongs to the class of drugs known as carbonic anhydrase inhibitors, while brimonidine tartrate is an alpha-2 adrenergic receptor agonist.
The combination of these two ingredients in Simbrinza Ophthalmic helps to reduce the production of fluid inside the eye, thereby lowering the intraocular pressure. By effectively lowering the IOP, Simbrinza Ophthalmic helps to prevent damage to the optic nerve, which can occur as a result of increased pressure in the eye.
Simbrinza Ophthalmic works by targeting two different mechanisms involved in the regulation of intraocular pressure. The brinzolamide component of Simbrinza inhibits carbonic anhydrase, an enzyme responsible for the production of fluid in the eye. By inhibiting this enzyme, brinzolamide reduces the amount of fluid produced, leading to a decrease in intraocular pressure.
The brimonidine tartrate component of Simbrinza works by stimulating alpha-2 adrenergic receptors in the eye. Activation of these receptors leads to a decrease in the production of aqueous humor, the fluid that fills the anterior chamber of the eye. The reduction in aqueous humor production helps to lower intraocular pressure.
Simbrinza Ophthalmic’s dual mechanism of action makes it an effective treatment option for patients with open-angle glaucoma or ocular hypertension, as it addresses both fluid production and outflow.

Open-angle glaucoma refers to a group of eye diseases characterized by increased intraocular pressure (IOP) that damages the optic nerve over time. It is the most common form of glaucoma, accounting for approximately 90% of all cases. Unlike other types of glaucoma, open-angle glaucoma typically develops gradually and painlessly, often without noticeable symptoms until the later stages. The exact cause of open-angle glaucoma is still unknown. However, several factors contribute to the development of this condition including increased intraocular pressure (IOP), age, family history, ethnicity and medical conditions. In the early stages, open-angle glaucoma typically doesn’t cause noticeable symptoms. As the condition progresses, some noticeable symptoms may include gradual loss of peripheral vision, blurred vision, increased sensitivity to light, difficulty adjusting to darkness and halos around lights.
Ocular hypertension is a condition characterized by elevated intraocular pressure (IOP) above the normal range, typically measured using a tonometer. The normal range of IOP is considered to be between 10 and 21 mmHg (millimeters of mercury). However, individuals with ocular hypertension have IOP readings consistently above 21 mmHg, without any signs of optic nerve damage or vision loss. The exact cause of ocular hypertension is often unknown. However, there are several risk factors that can contribute to its development including family history, age, ethnicity, certain medical conditions, steroid use (tropical or systemic), and eye trauma or injury. In most cases, ocular hypertension does not cause any noticeable symptoms or vision changes. The condition is typically asymptomatic, which makes regular eye exams crucial for early detection. Ocular hypertension is often discovered during routine eye screenings or examinations for other eye-related issues.
Warnings and Precautions
While Simbrinza can effectively manage these conditions, it is essential to be aware of the warnings and precautions associated with its use.

How To Use
Using Simbrinza ophthalmic correctly is essential to ensure its effectiveness and minimize the risk of side effects.
- Wash Your Hands: Start by washing your hands thoroughly with soap and water. This step helps prevent contamination of the eye drops.
- Shake the Bottle: Gently shake the Simbrinza eye drop bottle to ensure the suspension is well mixed. Do not skip this step, as it ensures the proper distribution of the active ingredients.
- Tilt Your Head Back: Tilt your head back slightly, or lie down comfortably. Look upward toward the ceiling.
- Pull Down Your Lower Eyelid: Using your index finger, gently pull down your lower eyelid to create a small pocket.
- Administer the Eye Drops: Hold the bottle upside down, close to your eye, and squeeze it gently to instill one drop into the pocket formed by your lower eyelid. Be careful not to touch your eye or eyelid with the tip of the bottle.
- Close Your Eye: Close your eye gently, without blinking, for about 1 to 2 minutes. This allows the medication to be absorbed properly.
- Repeat if Necessary: If your doctor has prescribed more than one drop per eye, wait for at least 5 minutes before instilling the next drop. This interval ensures that each drop is absorbed effectively.
- Replace the Cap: After using the eye drops, replace the cap tightly on the bottle to prevent contamination and preserve the remaining medication.
- Wipe Excess Liquid: If any excess liquid is present around your eyes, gently wipe it away with a clean tissue or cloth.
It is important to follow your doctor’s instructions regarding the dosage and frequency of Simbrinza ophthalmic eye drops. Do not exceed the prescribed dosage, as it can increase the risk of side effects without providing additional benefits.
Proper dosing is essential to ensure the medication’s effectiveness and minimize the risk of side effects.
Dosage for Adults
The recommended dosage of Simbrinza for adults is one drop in the affected eye(s) three times daily. It is important to follow the instructions provided by your healthcare provider regarding the number of drops and the frequency of administration.
Dosage for Pediatric Patients
The safety and efficacy of Simbrinza ophthalmic have not been established in pediatric patients below the age of 2 years. For children aged 2 years and older, the dosage is the same as that for adults, which is one drop in the affected eye(s) three times daily.
Simbrinza should be used three times a day at regular intervals. It is recommended to space the doses evenly throughout the waking hours to maintain a consistent level of the medication in the eye.
Missed Dose Instructions
If you miss a dose of Simbrinza, administer it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one.
Overdose Symptoms and Actions
If you accidentally use more than the prescribed dose of Simbrinza, you may experience symptoms such as dizziness, headache, or slow heart rate. In case of an overdose, seek immediate medical attention or contact your local poison control center. Do not drive or operate machinery if you are experiencing any adverse effects.
To ensure the effectiveness and safety of this medication, it’s essential to store it properly.
- Keep the medication in its original container: The manufacturer’s packaging is designed to protect the medication from light and air. It is best to leave the medication in its original container to maintain its integrity.
