Formula Information

A small arrow pointing down

Quinidine Sulfate 300 mg Slow Release Capsules are a specialized medication primarily used in the treatment of various cardiac arrhythmias, including atrial fibrillation, atrial flutter, and ventricular tachycardia. This particular formulation is compounded with Methocel E4M, a type of controlled-release polymer. The purpose of this polymer is to gradually release the encapsulated medication, in this case, quinidine sulfate, over an extended period of time.

The slow and steady release of the active ingredient allows for a more consistent therapeutic effect, offering sustained relief from the symptoms of cardiac arrhythmias. This controlled and prolonged release profile not only enhances the efficacy of the medication but also reduces the dosing frequency, thereby improving patient compliance. Furthermore, the slow release formulation helps to mitigate the risk of potential side effects associated with quinidine sulfate, such as dizziness, nausea, and headache.

Quinidine Sulfate 300 mg Slow Release Capsules have proven to be an effective treatment for cardiac arrhythmias and are generally well tolerated by most patients. However, it is crucial to note that quinidine sulfate can interact with other medications. Therefore, it is strongly recommended to discuss all current medications with your healthcare provider before initiating this treatment.

How Does it Work

A small arrow pointing down

Quinidine Sulfate 300 mg Slow Release Capsules are a specialized formulation designed to treat conditions such as atrial fibrillation, ventricular tachycardia, and atrial flutter. This unique formulation incorporates Methocel E4M, a controlled-release polymer, which ensures the gradual release of the active ingredient, quinidine sulfate, over an extended period. This slow release mechanism helps maintain a steady level of the drug in the body, providing consistent therapeutic effects.

The capsule is designed to be taken once daily, with or without food. Consistency is key, so it's important to take the capsule at the same time each day to ensure stable levels of the drug in the body. Quinidine sulfate works by blocking certain electrical signals in the heart, helping to regulate heart rate and rhythm. It's crucial to follow your doctor's prescription, as it can take several weeks for the full effects of the medication to be seen.

Regular monitoring of your heart rate and rhythm is recommended while taking quinidine sulfate. If you experience any side effects such as dizziness, lightheadedness, or an irregular heartbeat, it's important to contact your doctor immediately. Quinidine sulfate may interact with other medications, so it's essential to inform your doctor of any other drugs you are currently taking.
