Gabapentina and its uses

The Role of Gabapentin in Medical Treatment

Anticonvulsions such as gabapentin are mainly prescribed to control seizures by reducing abnormal electrical activity of the brain. They act by inhibiting excitement and enhancing the inhibitory effects of gamma-aminobutyric acid (GABA), an important neurotransmitter.

Apart from its anticonvulsing properties, gabapentin is also usually used in the treatment of nerve pain, such as neuropathic pain. This type of pain is usually chronic and is due to damage or nerve dysfunctions. Gabapentin helps relieve neuropathic pain acting on the calcium channels of the nerves, which reduces the release of certain neurotransmitters involved in the transmission of pain signals to the brain.

Gabapentina has also revealed effective in the treatment of restless legs syndrome (SPI), a disorder characterized by an irresistible need to move your legs, often accompanied by uncomfortable sensations. It is believed to reduce the abnormal activity of the central nervous system that causes these symptoms.

It can be prescribed as monotherapy (unique medicine) or as part of a combined therapy for certain conditions. The dose and the duration of the treatment will also be determined by health professionals based on factors such as the severity of the condition, the patient’s response to the medication and the possible side effects.

It is recommended to avoid taking antacids in the two hours of the administration of Gabapentina. This helps prevent any reduction in drug effectiveness, ensuring that it reaches systemic circulation correctly.

What to take into account: if you require the use of antacids, eat it with your medical care provider, who can suggest adjusting the schedule of your dose of gabapentin or considering alternative acid reducers that do not interfere with absorption.

2. 2. Opiates: the combination of gabapentin with opioids, such as codeine or oxycodone, can enhance its sedative effects, being able to cause excessive drowsiness, respiratory depression or even coma. It is essential to inform the health professional about the simultaneous consumption of opiates, since it may be necessary to adjust the dose of one or another medication to minimize these risks.

What to take into account: if you experience an increase in drowsiness, difficulty breathing or any other worrying symptom while using gabapentin and opioids together, seek immediate medical attention.

3. Antidepressants: certain antidepressants, such as fluoxetine or paroxetine, can increase blood concentration of gabapentin and prolong its effects. This can increase the risk of side effects associated with gabapentin, such as dizziness or drowsiness. The surveillance of these symptoms is essential if you are taking medications for depression or anxiety simultaneously with gabapentina.

What should be taken into account: Always report to your health professional if you are taking an antidepressant, and be attentive to any unusual or annoying side effect while using gabapentin. An adjustment of the dose or an alternative treatment may be necessary.

Examples of medications that interact with gabapentin:
Medicines Potential interaction
Antacids Reduction of gabapentin absorption
Opiates Possibility of excessive sedation
Antidepressants Increased blood gabapentin concentration

It is important to keep in mind that this is not an exhaustive list and that there may be other medications that interact with gabapentina. Always consult your doctor or pharmacist before starting or stop taking any medication while taking gabapentina to guarantee your safety and optimize the effectiveness of your treatment.
