Formula Information

A small arrow pointing down

Carbidopa 25 mg/Levodopa 100 mg Rectal Suppository is a specialized formulation designed for rectal administration. This solid dosage form is inserted into the rectum, where it dissolves or melts to release the medication. The medication is then absorbed locally or systemically, depending on the specific needs of the patient.

The combination of Carbidopa and Levodopa is primarily used to treat symptoms of Parkinson's disease, a condition characterized by muscle stiffness, tremors, and changes in speech and gait. Levodopa is converted to dopamine in the brain, helping to control these symptoms. Carbidopa, on the other hand, prevents the breakdown of Levodopa before it reaches the brain, increasing its effectiveness.

Rectal administration of this medication can be particularly beneficial for patients who have difficulty swallowing pills or for those who experience nausea or vomiting when taking oral medication. It can also provide a more consistent release of medication, which can be beneficial in managing the symptoms of Parkinson's disease.

It's important to note that while this medication can help manage the symptoms of Parkinson's, it does not cure the disease. Regular monitoring and dose adjustments may be necessary to ensure optimal symptom control and to minimize side effects. Common side effects can include nausea, dizziness, and orthostatic hypotension. More serious side effects, such as hallucinations or psychosis, can occur and should be reported to a healthcare provider immediately.

As compounding pharmacists, we can customize this formulation to meet the specific needs of each patient. This includes adjusting the dose, changing the base to accommodate allergies or sensitivities, or adding flavorings to improve taste. We work closely with prescribers to ensure each patient receives the most effective and tolerable treatment.

If you have any questions about this formulation or how it can be customized to meet your needs, please don't hesitate to reach out to us at Bayview Pharmacy. We are here to help and provide the most comprehensive care possible.

Drug Interactions

A small arrow pointing down

Carbidopa and Levodopa are medications used together to treat the symptoms of Parkinson's disease or Parkinson-like symptoms such as shakiness, stiffness, and difficulty moving. Carbidopa helps Levodopa to work more effectively by preventing it from being broken down before it reaches the brain. This combination medication is delivered via a rectal suppository, which allows for the medication to be absorbed directly into the bloodstream for a quicker and more efficient effect.

It's important to be aware of potential drug interactions when using Carbidopa/Levodopa. Certain medications can affect how Carbidopa/Levodopa works or increase the risk of side effects. These include certain antidepressants, antipsychotics, antihypertensives, and other medications used to treat Parkinson's disease. It's crucial to inform your healthcare provider about all the medications you are currently taking, including prescription drugs, over-the-counter medications, and herbal supplements.

Carbidopa/Levodopa can interact with a class of medications known as Monoamine Oxidase Inhibitors (MAOIs). Using Carbidopa/Levodopa with MAOIs can cause a serious (possibly fatal) drug interaction. Avoid taking isocarboxazid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, or tranylcypromine during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before treatment with this medication.

High-protein diets can also affect the absorption of Levodopa. Consuming a diet high in protein can prevent Levodopa from reaching the brain, where it is needed to control symptoms of Parkinson's disease. Therefore, it's recommended to consume a balanced diet while on this medication.

Alcohol can increase the risk of side effects from Carbidopa/Levodopa, such as dizziness, confusion, and difficulty concentrating. It's recommended to limit alcohol consumption while using this medication.

It's also important to note that Carbidopa/Levodopa can cause a false result in certain medical tests, including urine tests for glucose (sugar) and ketones. If you are scheduled for any medical tests, inform your healthcare provider that you are using this medication.

This is not a complete list of possible drug interactions. Always consult with your healthcare provider or pharmacist for more information. If you have any questions, don't hesitate to reach out to us at Bayview Pharmacy. We are here to help.

How Does it Work

A small arrow pointing down

The Carbidopa 25 mg/Levodopa 100 mg Rectal Suppository is a solid dosage form that is inserted into the rectum, where it dissolves or melts to release the medication. This formulation is designed for local or systemic absorption, depending on the specific needs of the patient.

Carbidopa and Levodopa are two active ingredients in this formulation. Levodopa is converted into dopamine in the brain, which helps to control movement. However, when taken orally, a large amount of Levodopa is broken down in the body before it can reach the brain. This is where Carbidopa comes in. Carbidopa prevents Levodopa from being broken down before it reaches the brain, allowing more Levodopa to get to the brain and be converted into dopamine.

This combination of Carbidopa and Levodopa is commonly used to treat symptoms of Parkinson's disease, a neurodegenerative disorder that affects movement. Symptoms of Parkinson's disease are caused by a lack of dopamine in the brain. By increasing the amount of dopamine in the brain, this formulation can help to reduce symptoms such as tremors, stiffness, and difficulty with balance and coordination.

Using this medication in a rectal suppository form can have several benefits. For patients who have difficulty swallowing pills, a rectal suppository can be an easier method of administration. Additionally, this form of administration can allow for a more steady and consistent release of medication, which can help to maintain more consistent levels of dopamine in the brain.

It's important to note that while this formulation can help to manage symptoms of Parkinson's disease, it does not cure the disease. It can, however, significantly improve quality of life for individuals living with this condition. As with any medication, it's important to discuss potential side effects and interactions with your healthcare provider.

Other Uses

A small arrow pointing down

Carbidopa/Levodopa rectal suppositories are primarily used in the management of symptoms of Parkinson's disease, such as tremors, stiffness, and difficulty moving. This formulation works by improving the transport of levodopa into the brain, where it can have a direct effect on the dopaminergic neurons that are deficient in Parkinson's disease.

However, there can be other uses for this formulation. It might be used in certain cases of Restless Legs Syndrome (RLS), a condition characterized by an uncontrollable urge to move the legs. Levodopa is sometimes used in patients with severe symptoms who do not respond to first-line treatments. Carbidopa is combined with levodopa to prevent the peripheral degradation of levodopa, allowing more to cross the blood-brain barrier.

Another potential use for this form of therapy could be in the management of dopamine-responsive dystonia (DRD). DRD is a rare form of dystonia that has a positive response to levodopa therapy, and carbidopa can enhance levodopa's therapeutic effects by limiting its peripheral degradation.

Despite these other potential uses, it's essential to remember that treatment should always be individualized to meet the specific needs of each patient. Additionally, caution should be exercised while using this formulation due to the risk of potential side effects, such as nausea, dizziness, and headache. Also, special attention is required in patients with a history of cardiovascular or pulmonary conditions given that levodopa can cause orthostatic hypotension.

If you have any questions about this formulation or its diverse uses, do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding professionals is more than willing to provide you with the information and advice you require.
