What is a blue round pill with M 711 on it?
A blue, round pill with the imprint 'M 711' is a combination prescription medication containing Carbidopa (10 mg) and Levodopa (100 mg). This medication is manufactured by Mylan Pharmaceuticals Inc. and is primarily used to treat the symptoms of Parkinson's disease. It is classified as a dopaminergic antiparkinsonism agent. Identification of any pill should always be confirmed by a healthcare professional or pharmacist, but online pill identification tools consistently link this specific imprint and appearance to this medication.
How Carbidopa-Levodopa works
The dual-agent composition of this medication is vital for its effectiveness. In Parkinson's disease, nerve cells in the brain that produce dopamine are slowly lost, leading to a deficiency of this important neurotransmitter. Levodopa is a precursor to dopamine and can cross the blood-brain barrier, where it is converted into dopamine to replace the missing chemical.
Carbidopa's role is to prevent Levodopa from being metabolized in the bloodstream and other parts of the body before it reaches the brain. This allows more Levodopa to reach the central nervous system, where it can be converted to dopamine. By ensuring more of the dose is delivered where it is needed, Carbidopa helps reduce the amount of Levodopa required and minimizes systemic side effects.
Uses and dosage for the M 711 pill
Therapeutic uses
The primary therapeutic use of Carbidopa-Levodopa is the management of Parkinson's disease. It helps control symptoms such as:
- Muscle stiffness
- Tremors
- Slowed movement (bradykinesia)
- Balance problems
It is important to note that this medication controls symptoms but does not cure the underlying disease. A healthcare provider determines the exact dosage based on the patient's condition and response to therapy. This drug is also sometimes used for Neuroleptic Malignant Syndrome and GTP-CH Deficiency.
How to take your medication
Proper administration is key to maximizing effectiveness and minimizing side effects. Dosage and timing should be strictly followed as directed by a physician.
- It should be taken with or shortly after a meal or a light snack to reduce stomach upset.
- The tablets can often be swallowed whole or broken in half along the score line, but they should not be crushed or chewed unless advised by a doctor.
- Consistency is important. Taking the medication around the same time each day can help maintain stable levels in the blood.
- Do not stop taking the medication abruptly, as this can lead to serious withdrawal symptoms.
Side effects and precautions
Like all medications, Carbidopa-Levodopa carries a risk of side effects, ranging from common and mild to more serious issues.
Common side effects
- Nausea and vomiting
- Dizziness or lightheadedness, especially when standing up quickly
- Unusual or jerky movements (dyskinesia)
- Dry mouth and changes in appetite
- Trouble sleeping or unusual vivid dreams
Serious side effects
- Orthostatic Hypotension and Syncope: Sudden drops in blood pressure upon standing can cause fainting. Patients should rise slowly from a sitting or lying position.
- Cardiovascular Effects: In rare cases, heart arrhythmias, palpitations, or other heart rhythm problems can occur. This risk increases for patients with pre-existing heart conditions.
- Psychiatric Disturbances: Mood or behavioral changes such as agitation, confusion, hallucinations, or depression can occur.
- Gastrointestinal Bleeding: There is an increased risk of bleeding, especially when taken with blood thinners or NSAIDs.
Important precautions
- Drug Interactions: Inform your doctor and pharmacist about all medications and supplements you are taking. Interactions can occur with MAOIs, other antidepressants, and certain antibiotics.
- Alcohol: Avoid or limit alcohol consumption, as it can worsen side effects like drowsiness and dizziness.
- Pregnancy and Breastfeeding: Consult with a healthcare provider before using this medication if pregnant, planning to become pregnant, or breastfeeding.
- Underlying Health Conditions: Patients with a history of heart disease, psychiatric disorders (especially bipolar disorder), glaucoma, or bleeding problems should use this medication with caution and close monitoring.
Comparison of Carbidopa and Levodopa
| Feature | Carbidopa | Levodopa |
|---|---|---|
| Primary Role | Prevents the breakdown of Levodopa outside the brain. | Acts as a precursor to dopamine; crosses the blood-brain barrier. |
| Mechanism | Inhibits the enzyme DOPA decarboxylase in the periphery. | Converted to dopamine in the brain to replenish low levels. |
| Effect | Does not have a significant effect on its own. | Reduces motor symptoms of Parkinson's disease once converted to dopamine. |
| Reason for Combination | Increases the amount of Levodopa available to the brain and reduces systemic side effects. | Provides the essential building block for producing dopamine in the brain. |
Conclusion
In conclusion, a blue round pill with the imprint M 711 is a specific dosage of Carbidopa-Levodopa, a vital medication used to manage the symptoms of Parkinson's disease. This dual-ingredient drug works by enhancing the brain's dopamine supply to improve motor function. Because it is a powerful prescription medication, it is crucial to use it only under a doctor's guidance, adhere to the prescribed dosage, and be aware of potential side effects and drug interactions. Patients should always consult a healthcare provider for proper diagnosis and treatment and never rely on visual pill identification alone.
