Formula Information

A small arrow pointing down

Carbamazepine 200 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 this should be taken into account when determining the appropriate dosage and frequency of administration.

As with all medications, 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 the healthcare provider immediately.

It's also important to note that Carbamazepine can interact with a number of other medications, potentially altering their effectiveness or increasing the risk of side effects. Therefore, patients should inform their healthcare provider of all medications they are currently taking, including prescription drugs, over-the-counter medications, and dietary supplements.

Drug Interactions

A small arrow pointing down

Carbamazepine is an anticonvulsant medication used primarily in the treatment of epilepsy and neuropathic pain. It works by reducing the spread of seizure activity in the brain and restoring the normal balance of nerve activity. As a rectal suppository, it is designed to be absorbed through the rectal tissue into the bloodstream. This route of administration can be beneficial for patients who have difficulty swallowing tablets or for whom oral administration is not suitable.

However, Carbamazepine can interact with a number of other medications, potentially altering their effects or increasing side effects. It is important for patients and prescribers to be aware of these potential interactions.

Carbamazepine can decrease the effectiveness of certain drugs such as warfarin, doxycycline, theophylline, and oral contraceptives. Therefore, alternative or additional contraceptive methods are recommended for women using Carbamazepine. It can also interact with other antiepileptic drugs like phenytoin, phenobarbital, and valproic acid, potentially requiring dose adjustments.

Conversely, certain drugs can affect the metabolism of Carbamazepine, leading to increased blood levels and potential toxicity. These include macrolide antibiotics (such as erythromycin), certain antifungal medications (like ketoconazole), and calcium channel blockers (like verapamil).

Carbamazepine can also interact with grapefruit juice, which can increase the levels of the drug in the body and lead to increased side effects. Therefore, consumption of grapefruit and grapefruit juice should be avoided while taking this medication.

Alcohol can increase the nervous system side effects of Carbamazepine such as dizziness, drowsiness, and difficulty concentrating. It is advisable to avoid or limit the use of alcohol while being treated with Carbamazepine.

It is important to inform your healthcare provider about all the medications you are currently taking, including over-the-counter drugs, vitamins, and herbal supplements, to avoid any potential drug interactions. Never start a new medication without consulting your healthcare provider.

How Does it Work

A small arrow pointing down

Carbamazepine 200 mg Rectal Suppository is a solid dosage form that is inserted into the rectum, where it dissolves or melts to release the medication. Carbamazepine is an anticonvulsant or antiepileptic drug that works by reducing the spread of seizure activity in the brain and restoring the normal balance of nerve activity. It is also used to relieve certain types of nerve pain such as trigeminal neuralgia.

The rectal route of administration is particularly useful for patients who are unable to take medications orally, such as those who are unconscious, nauseous, or having seizures. The rectal mucosa has a rich blood supply, which allows for the rapid absorption of the medication into the systemic circulation. This can provide a quick onset of action, which is often necessary in acute seizure situations.

Once the suppository is inserted into the rectum, it begins to melt due to the body's heat. As it melts, the carbamazepine is released and absorbed through the rectal mucosa into the bloodstream. From there, it is transported to the brain where it exerts its therapeutic effects. Carbamazepine works by stabilizing the hyper-excited nerve fibers in the brain, preventing them from firing excessively and causing seizures.

It's important to note that the effectiveness of carbamazepine can be influenced by various factors, including the patient's overall health, the presence of other medications, and individual genetic factors that can affect how the drug is metabolized in the body. Therefore, the dose and frequency of administration should be individualized based on the patient's response and tolerance to the medication.

Carbamazepine 200 mg Rectal Suppository can be a valuable treatment option for patients with epilepsy or nerve pain who cannot take oral medications. However, like all medications, it should be used under the supervision of a healthcare provider, and any side effects or concerns should be reported immediately.

If you have any questions about this formulation, please don't hesitate to reach out to us at Bayview Pharmacy. Our team of knowledgeable compounding pharmacists is always here to help.

Other Uses

A small arrow pointing down

Aside from its known application in common disease management, Carbamazepine 200 mg Rectal Suppository formulation can also be used for other purposes. This suppository's alternative applications include management of bipolar disorder, trigeminal neuralgia, and certain types of seizures in adults and children. Notably, Carbamazepine serves as a mood stabilizer and has shown effectiveness against manic episodes in bipolar disorder. Its analgesic properties effectively manage trigeminal neuralgia, a facial nerve disorder that causes extreme, sporadic, sudden burning or shock-like face pain that lasts for a couple seconds to two minutes per episode. These episodes can occur in quick succession. Additionally, the formulation is an anticonvulsant, boosting its application for certain seizure types. However, patients should note that use for these conditions should be under the strict direction of a healthcare provider, as Carbamazepine can have significant side effects that need careful management.

From a physiological perspective, the use of a rectal suppository allows for direct absorption in the rectum, sidestepping first-pass metabolism, and providing a better absorption rate. This can be particularly beneficial in patients who are unconscious, uncooperative, nauseous, or prone to vomit, as well as in situations where oral medication application isn't feasible due to surgery or gastrointestinal issues. Also, this formulation could be useful for patients where a controlled, sustained release of medication is desirable.

Prescribers should take note that while this formulation is promising, they must consider the specific patient's pharmacokinetics and drug interactions. Carbamazepine can lead to induction of liver enzymes, potentially reducing the effectiveness of other medications— including oral contraceptives and some anticoagulants. As a result, patient medical history and concurrent medication regimen need careful review before prescribing this formulation.
