Formula Information

A small arrow pointing down

Carbamazepine 300 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 active ingredient, Carbamazepine, is then absorbed locally or systemically to exert its therapeutic effects.

Carbamazepine is an anticonvulsant and mood-stabilizing drug used primarily in the treatment of epilepsy and bipolar disorder. It is also used to treat trigeminal neuralgia, a condition that causes severe facial pain. The rectal suppository form of Carbamazepine provides an alternative route of administration for patients who may have difficulty swallowing tablets or for whom oral administration is not suitable.

The rectal route of administration allows for the medication to be absorbed directly into the bloodstream, bypassing the first-pass metabolism in the liver. This can result in a more rapid onset of action and potentially fewer side effects. However, it's important to note that individual absorption rates can vary, and the full effects of the medication may not be felt immediately.

As with any medication, Carbamazepine Rectal Suppositories should be used under the supervision of a healthcare provider. Patients should be monitored for potential side effects, which may include dizziness, drowsiness, unsteadiness, nausea, and vomiting. Any adverse reactions should be reported to a healthcare provider immediately.

It's also important to note that Carbamazepine can interact with other medications, so patients should inform their healthcare provider of all medications they are currently taking. This includes prescription medications, over-the-counter drugs, and dietary supplements.

Carbamazepine Rectal Suppositories are a specialized formulation that requires compounding by a pharmacist. At Bayview Pharmacy, our team of knowledgeable compounding pharmacists is here to answer any questions you may have about this formulation. Please don't hesitate to reach out to us for more information.

Drug Interactions

A small arrow pointing down

Carbamazepine is an anticonvulsant medication that is used to treat various conditions such as epilepsy, trigeminal neuralgia, and bipolar disorder. It works by reducing the abnormal electrical activity in the brain, which helps to prevent seizures and episodes of extreme mood swings.

When used as a rectal suppository, the medication is absorbed through the rectal tissue and enters the bloodstream, providing systemic effects. This route of administration can be beneficial for patients who have difficulty swallowing tablets or for those who cannot tolerate oral medications due to nausea or vomiting.

However, it's important to be aware of potential drug interactions when using carbamazepine. This medication can interact with a wide range of other drugs, potentially altering their effects or increasing the risk of side effects.

Carbamazepine can decrease the effectiveness of certain medications, including some types of birth control (like oral contraceptives, patches, or rings), anticoagulants (like warfarin), and certain HIV medications. If you're taking any of these medications, your healthcare provider may need to adjust your dosage or monitor you more closely for side effects.

Conversely, certain medications can increase the levels of carbamazepine in your body, potentially leading to toxicity. These include certain antifungal medications (like fluconazole), macrolide antibiotics (like erythromycin), and calcium channel blockers (like diltiazem).

Additionally, carbamazepine can interact with grapefruit juice, which can increase the levels of the medication in your body and increase the risk of side effects. It's generally recommended to avoid consuming grapefruit or grapefruit juice while taking this medication.

It's important to tell your healthcare provider about all the medications, supplements, and herbal products you're currently taking before starting treatment with carbamazepine. This will help to ensure that the medication is safe and effective for you.

Remember, this is not a complete list of potential drug interactions. Always consult with your healthcare provider or pharmacist for personalized advice regarding drug interactions. If you have any questions or concerns, don't hesitate to reach out to us at Bayview Pharmacy. We're here to help.

How Does it Work

A small arrow pointing down

Carbamazepine 300 mg Rectal Suppository is a solid dosage form that is inserted into the rectum, where it dissolves or melts to release the medication. The active ingredient, Carbamazepine, is then absorbed into the bloodstream through the rectal mucosa. This route of administration bypasses the first-pass metabolism in the liver, which can be beneficial for patients who have difficulty swallowing tablets or for those who need immediate relief from symptoms.

Carbamazepine is an anticonvulsant and mood-stabilizing drug used primarily in the treatment of epilepsy and bipolar disorder, as well as trigeminal neuralgia. It works by reducing excessive nerve signals in the brain and restoring the normal balance of nerve activity. Specifically, it stabilizes hyper-excited nerve fibers, inhibits repetitive neuronal firing, and reduces post-tetanic potentiation.

In the case of epilepsy, Carbamazepine can help to reduce the frequency of seizures by stabilizing the electrical activity in the brain. For patients with bipolar disorder, it can help to reduce episodes of mania or depression. In treating trigeminal neuralgia, it works by altering nerve impulses that cause severe facial pain.

It's important to note that while Carbamazepine can help control symptoms, it does not cure these conditions. Regular use as directed by a healthcare provider is necessary to obtain the maximum benefit of this medication. Side effects can occur, including dizziness, drowsiness, unsteadiness, nausea, and vomiting. If these persist or worsen, or if more serious side effects occur, the patient should contact their healthcare provider immediately.

As compounding pharmacists, we can customize this medication to the specific needs of the patient, including adjusting the dose or changing the form of administration. We can also add flavorings to make the medication more palatable, or remove certain ingredients to prevent allergic reactions. If you have any questions about Carbamazepine 300 mg Rectal Suppository or any other medication, please don't hesitate to reach out to us at Bayview Pharmacy.

Other Uses

A small arrow pointing down

Carbamazepine is primarily used to control different types of seizures in epilepsy and relieve certain types of nerve pain such as trigeminal neuralgia. Given its use as an antiepileptic and neuropathic pain reliever, it is also often used off-label for a variety of conditions.

In psychiatric practice, Carbamazepine can be used as a mood stabilizer in bipolar disorder, especially with patients who do not respond well to other mood stabilizers. It can also be used effectively in the treatment of acute manic episodes and maintenance of bipolar disorder.

Another off-label use of Carbamazepine includes its use for alcohol withdrawal syndrome to manage the symptoms better. Carbamazepine has also been used effectively in the treatment of restless legs syndrome and postherpetic neuralgia, a painful condition that can follow shingles.

Lastly, Carbamazepine has shown some benefit in the treatment of certain forms of tinnitus. The 300 mg rectal suppository formulation allows for a more continuous and steady release of medication, which might be beneficial for some of these off-label uses.

However, it’s crucial that prescribers obtain informed consent when prescribing medications off-label and patients should know that these uses are not reviewed or approved by the FDA. As always, the potential benefits and risks of any medication should be weighed carefully. If you have any further questions about the uses of this formulation, please don't hesitate to reach out to us at Bayview Pharmacy.
