What is Syndopa 275?

Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) combination is used to treat Parkinson's disease, sometimes called shaking palsy or paralysis agitans. Parkinson's disease is a disorder of the central nervous system (brain and spinal cord).

Extended-release Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) (Syndopa 275®) is also used to treat parkinsonism caused by encephalitis, or parkinsonism caused by carbon monoxide or manganese poisoning.

Dopamine is a naturally occurring substance in the brain that helps provide control of movement and activities such as walking and talking. In patients with Parkinson's disease, there is not enough dopamine in some parts of the brain. Levodopa (Syndopa 275) enters the brain and helps replace the missing dopamine, which allows people to function better. By increasing the amount of dopamine in the brain, Levodopa (Syndopa 275) helps control symptoms and helps you to perform daily activities such as dressing, walking, and handling utensils.

Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) is available only with your doctor's prescription.

Syndopa 275 indications

Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) orally disintegrating tablets are indicated in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) orally disintegrating tablets are indicated in these conditions to permit the administration of lower doses of Levodopa (Syndopa 275) with reduced nausea and vomiting, with more rapid dosage titration, with a somewhat smoother response, and with supplemental pyridoxine (vitamin B6).

In some patients, a somewhat smoother antiparkinsonian effect results from therapy with Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) than with Levodopa (Syndopa 275). However, patients with markedly irregular (“on-off”) responses to Levodopa (Syndopa 275) have not been shown to benefit from Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) therapy.

Although the administration of Carbidopa (Syndopa 275) permits control of parkinsonism and Parkinson’s disease with much lower doses of Levodopa (Syndopa 275), there is no conclusive evidence at present that this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to Levodopa (Syndopa 275).

Certain patients who responded poorly to Levodopa (Syndopa 275) have improved when Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) was substituted. This is most likely due to decreased peripheral decarboxylation of Levodopa (Syndopa 275) which results from administration of Carbidopa (Syndopa 275) rather than to a primary effect of Carbidopa (Syndopa 275) on the nervous system. Carbidopa (Syndopa 275) has not been shown to enhance the intrinsic efficacy of Levodopa (Syndopa 275) in parkinsonian syndromes.

In considering whether to give Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) orally disintegrating tablets to patients already on Levodopa (Syndopa 275) who have nausea and/or vomiting, the practitioner should be aware that, while many patients may be expected to improve, some do not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) with Levodopa (Syndopa 275), about half of the patients with nausea and/or vomiting on Levodopa (Syndopa 275) improved spontaneously despite being retained on the same dose of Levodopa (Syndopa 275) during the controlled portion of the trial.

How should I use Syndopa 275?

Use Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) 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 Carbidopa (Syndopa 275) and Levodopa (Syndopa 275).

Uses of Syndopa 275 in details

sponsored

This medication is used to treat symptoms of Parkinson's disease (such as shakiness, stiffness, difficulty moving).

Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa (Syndopa 275) changes into dopamine in the brain, helping to control movement. Carbidopa (Syndopa 275) prevents the breakdown of Levodopa (Syndopa 275) in the bloodstream so more Levodopa (Syndopa 275) can enter the brain. Carbidopa (Syndopa 275) can also reduce some of Levodopa (Syndopa 275)'s side effects such as nausea and vomiting.

By giving this medication as a continuous infusion, it can help reduce the amount of "off" time (periods of slow movement or stiffness).

How to use Carbidopa (Syndopa 275)-Levodopa (Syndopa 275) via j-tube

Read the Medication Guide and the Instructions for Use provided by your health care professional before you start using this medication and each time you get a refill. If you have any questions, ask your health care professional.

Give this medication as directed as a continuous infusion into the small intestine using an infusion pump. It is usually given over 16 hours a day and stopped at bedtime. At bedtime, take your dose of immediate-release Syndopa 275 tablets by mouth as directed.

When you first start using this medication, it is given through a tube through the nose into the small intestine. After a few days, if the doctor decides that this product is right for you, then the medication will be given through a tube through the abdomen into the small intestine. Getting the tube through the abdomen will require surgery.

Follow all instructions from your health care professional about how to properly use this medication and the infusion pump. Take a cassette containing the medication from the refrigerator and leave it at room temperature for 20 minutes before using. Do not use a cassette for longer than 16 hours or re-use it, even if there is medication left in it. Learn how to store and discard medical supplies safely. Also learn how to properly care for the small hole in your abdomen and the skin area around the tube, and how to avoid infection.

The dosage is based on your medical condition and response to treatment. Your daily dose is made up of a morning dose, a continuous dose, and extra doses. An extra dose is a small dose of this medication that can be given as needed during the day to treat sudden "off" symptoms. Extra doses should not be given more often than one every 2 hours to avoid causing or worsening movements you cannot control.

Do not suddenly decrease the dose or suddenly stop using this medication because doing either may lead to a serious condition. If you must stop this medication, slowly reduce the dose as directed by your doctor. Contact your doctor right away if your infusion is interrupted. You may need to take the tablet form of Syndopa 275 by mouth.

If you plan to be disconnected from the pump for a short period of time (less than 2 hours, for example, to shower), ask your doctor ahead of time if you should use an extra dose of this medication before you disconnect. If you plan to be disconnected from the pump for longer than 2 hours, ask your doctor what you should do and discuss how you should take Syndopa 275 tablets by mouth during this time.

Avoid high-protein diets because they may reduce how much of the medication you can absorb.

Tell your doctor if your condition does not improve or if it worsens.

Syndopa 275 description

sponsored

The naturally occurring form of dihydroxyphenylalanine and the immediate precursor of dopamine. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. It is used for the treatment of parkinsonian disorders and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.

Syndopa 275 dosage

Dosage in Patients Naïve to Levodopa (Syndopa 275) Therapy

The recommended starting dosage of Syndopa 275 in Levodopa (Syndopa 275)-naïve patients is 23.75 mg / 95 mg taken orally three times a day for the first 3 days. On the fourth day of treatment, the dosage of Syndopa 275 may be increased to 36.25 mg / 145 mg taken three times a day.

Based upon individual patient clinical response and tolerability, the Syndopa 275 dose may be increased up to a maximum recommended dose of 97.5 mg / 390 mg taken three times a day. The dosing frequency may be changed from three times a day to a maximum of five times a day if more frequent dosing is needed and if tolerated. The maximum recommended daily dose of Syndopa 275 is 612.5 mg / 2450 mg.

Maintain patients on the lowest dosage required to achieve symptomatic control and to minimize adverse reactions such as dyskinesia and nausea.

Converting from Immediate-Release Carbidopa (Syndopa 275)-Levodopa (Syndopa 275) to Syndopa 275

To convert patients from immediate-release Carbidopa (Syndopa 275)-Levodopa (Syndopa 275) to Syndopa 275, determine the recommended starting dosage of Syndopa 275 using Table 1.

The dosages of other Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) products are not interchangeable with the dosages of Syndopa 275.

Adjust the dose to maintain patient tolerance and sufficient symptomatic control. The dosing frequency may be changed from three times a day to a maximum of five times a day if more frequent dosing is needed and if tolerated. The maximum recommended daily dose of Syndopa 275 is 612.5 mg / 2450 mg.

For patients currently treated with Carbidopa (Syndopa 275) and Levodopa (Syndopa 275) plus catechol-O-methyl transferase (COMT) inhibitors (such as entacapone), the initial total daily dose of Levodopa (Syndopa 275) in Syndopa 275 described in Table 1 may need to be increased.

Use of Syndopa 275 in combination with other Levodopa (Syndopa 275) products has not been studied.

Monoamine Oxidase (MAO) Inhibitors

The use of nonselective MAO inhibitors with Syndopa 275 is contraindicated. Discontinue use of any nonselective MAO inhibitors at least two weeks prior to initiating Syndopa 275.

The use of selective MAO-B inhibitors (e.g., rasagiline and selegiline) with Syndopa 275 may be associated with orthostatic hypotension. Monitor patients who are taking these drugs.

Antihypertensive Drugs

The concurrent use of Syndopa 275 with antihypertensive medications can cause symptomatic postural hypotension. A dose reduction of the antihypertensive medication may be needed after starting or increasing the dose of Syndopa 275.

Dopamine D2 Receptor Antagonists And Isoniazid

Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone, metoclopramide, papaverine) and isoniazid may reduce the effectiveness of Levodopa (Syndopa 275). Monitor patients for worsening Parkinson's symptoms.

Iron Salts

Iron salts or multi-vitamins containing iron salts can form chelates with Levodopa (Syndopa 275), Carbidopa (Syndopa 275), and can cause a reduction in the bioavailability of Syndopa 275. If iron salts or multi-vitamins containing iron salts are co-administered with Syndopa 275, monitor patients for worsening Parkinson's symptoms.

High-Protein Diet

Because Levodopa (Syndopa 275) competes with certain amino acids for transport across the gut wall, the absorption of Levodopa (Syndopa 275) may be decreased in patients on a high-protein diet. Advise patients that a high-protein diet may reduce the effectiveness of Syndopa 275.
