Keppra, also known by its generic name levetiracetam, is a widely prescribed antiepileptic medication used to treat various types of seizures and epilepsy. As a crucial component of managing epilepsy, it's essential to understand the composition of Keppra, its mechanism of action, and how it helps patients control their seizures. In this article, we'll delve into the specifics of Keppra, exploring its active ingredients, formulation, and what sets it apart from other antiepileptic drugs.
The development of Keppra as a therapeutic option for epilepsy patients marks a significant advancement in the field of neurology. With its unique mechanism of action and relatively favorable side effect profile compared to other antiepileptic medications, Keppra has become a preferred choice for many healthcare providers and patients alike. However, to fully appreciate the benefits and potential drawbacks of Keppra, it's crucial to have a comprehensive understanding of its composition and how it works within the body.
Active Ingredients in Keppra
The primary active ingredient in Keppra is levetiracetam. Levetiracetam is a synthetic compound that was specifically designed to target and modulate neuronal excitability, thereby reducing the occurrence of seizures. Unlike many traditional antiepileptic drugs that act on specific ion channels or neurotransmitter systems, levetiracetam's mechanism of action is unique and involves binding to the synaptic vesicle protein 2A (SV2A). This interaction is thought to stabilize neuronal excitability and prevent the spread of seizure activity.
In addition to levetiracetam, Keppra formulations contain several inactive ingredients, or excipients, which are crucial for the drug's stability, bioavailability, and administration. These may include:
- Microcrystalline cellulose
- Croscarmellose sodium
- Magnesium stearate
- Silicon dioxide
The exact formulation of inactive ingredients may vary depending on the specific Keppra product, such as tablets, oral solutions, or extended-release formulations.
Formulations of Keppra
Keppra is available in several formulations to accommodate different patient needs and preferences. These include:
| Formulation | Description |
|---|---|
| Tablets | Immediate-release tablets available in various strengths (250 mg, 500 mg, 750 mg, and 1000 mg) |
| Oral Solution | A liquid formulation that contains 100 mg of levetiracetam per mL |
| Extended-Release Tablets | Formulated to release levetiracetam slowly over time, providing a prolonged therapeutic effect |
Each formulation is designed to ensure that patients can receive the appropriate dose of levetiracetam in a manner that suits their lifestyle and medical needs.

Mechanism of Action and Therapeutic Effects
The unique mechanism of action of levetiracetam contributes to its therapeutic effects in controlling seizures. By modulating neuronal excitability and preventing the spread of seizure activity, Keppra helps patients achieve better seizure control and improved quality of life. Clinical trials have demonstrated the efficacy of Keppra in reducing seizure frequency and severity in patients with various types of epilepsy.
Potential Side Effects and Considerations
Like all medications, Keppra can cause side effects, some of which may be serious. Common side effects include:
- Somnolence (drowsiness)
- Fatigue
- Headache
- Nausea
- Irritability
It's essential for patients to discuss potential side effects and any concerns with their healthcare provider to ensure the best possible treatment outcomes.
