Which agent should be avoided in the patient with epilepsy?

Which agent should be avoided in the patient with epilepsy?

For uncontrolled seizures, treatment with midazolam, thiopental, or propofol is acceptable; opioids should be avoided.

Are calcium channel blockers used to treat epilepsy?

Calcium has been established to play a major role in seizure occurrence, thus, calcium antagonists that can alter the effects of calcium on brain cells have been investigated for effect on epileptic seizures.

How does blocking sodium channels help epilepsy?

Voltage-gated sodium channels initiate action potentials in brain neurons, and sodium channel blockers are used in therapy of epilepsy. Mutations in sodium channels are responsible for genetic epilepsy syndromes with a wide range of severity.

How do sodium channels mutate to cause epilepsy?

There are several known causes for epilepsy; one of them is the malfunction of ion channels, resulting from mutations. Voltage-gated sodium channels (NaV) play an essential role in the generation and propagation of action potential, and malfunction caused by mutations can induce irregular neuronal activity.

What medications can cause seizures?

Drugs that lower the seizure threshold….

Can high blood sugar cause seizures?

Although it’s a common complication of diabetes, hyperglycemia can happen to anyone. If left untreated, high blood sugar can lead to hyperglycemia-related seizures.

Do Calcium channel blockers cause seizures?

Due to the highly complex and widespread effects of calcium channels, even small alterations in their expression or biophysical properties can induce pathophysiological changes in the brain with the potential to induce epileptic seizures.

How do calcium channel blockers work for seizures?

The ability of the T-type calcium channel antagonists to inhibit absence seizures and reduce the duration and cycle frequency of spike-and-wave discharges, also suggests that T-current generated by T-type calcium channels is a key component in the formation of absence seizures.

Is Lamotrigine a sodium channel blocker?

Sodium channels are specifically blocked by the anticonvulsant drug lamotrigine, which preferentially binds to the channel pore in the inactivated open state.

Are diabetes and epilepsy related?

Epilepsy or seizures are often observed in patients with diabetes mellitus (DM), and an emerging association between the two diseases is more than coincidental based on recent research. Approximately 25% of patients with DM experience different types of seizures.

Why is calcium important in epilepsy?

Children who take medicine for seizures due to epilepsy may be at higher risk for weak or breaking bones. This happens because these medicines change the way the body uses calcium and vitamin D, which are very important to keep bones strong. Exercise is also very important to keep bones strong.

How does sodium valproate work in epilepsy?

How does sodium valproate work? Sodium valproate is an anticonvulsant (or anti-epileptic) medicine. It prevents epileptic seizures by reducing excessive electrical activity in your brain. It’s not fully understood how this medicine works for treating bipolar disorder.

What is the drug of choice for epilepsy?

Sodium valproate and lamotrigine are the two drugs of choice for generalized epilepsies, as well as for undetermined epilepsies. Lamotrigine is often prefered for women of childbearing age.

Is Lamictal a high risk medication?

Lamotrigine (Lamictal) has been associated with a rare, but serious and life-threatening adverse reaction called hemophagocytic lymphohistiocytosis (HLH), which can lead to multi-organ failure resulting in hospitalization or death, particularly if diagnosis and treatment are delayed.

What are the long term side effects of lamotrigine?

To date, there are no known problems associated with long term use of lamotrigine. It is a safe and effective medication when used as directed.
