Lyrica is a type of anti-epileptic medicine which contains pregabalin active chemical ingredient. Lyrica can be used for various illness such as epilepsy nerve pain and anxiety. Lyrica is manufactured and marketed by Pfizer. Lyrica is sold 75, 150, and 300 mg versions in the market.
How does it work?
Lyrica capsules and oral solution both contain the active ingredient pregabalin, which is a medicine that is used for three different purposes - treating epilepsy, nerve pain and anxiety.
The way in which pregabalin works is not fully understood. It is thought to work by binding to calcium channels found on nerve cells in the brain and spinal cord. This reduces the release of various neurotransmitters from these nerve cells.
Neurotransmitters are natural body chemicals that are stored in nerve cells. They are involved in transmitting messages between the nerve cells. Pregabalin is thought to reduce the release of neurotransmitters called glutamate, noradrenaline and substance P.
Glutamate is a neurotransmitter that acts as a natural 'nerve-exciting' agent. It is released when electrical signals build up in nerve cells and subsequently excites more nerve cells. It is thought to play a key role in causing epileptic seizures. Reducing the release of glutamate from the nerve cells in the brain is thought to help stabilise the electrical activity in the brain and prevent epileptic fits.
Pregabalin is used as an add-on treatment for adults whose epilepsy has not been well controlled by other anti-epileptic medicines. It is used to prevent partial seizures, and partial seizures that spread to secondary generalised seizures.
Glutamate, substance P and noradrenaline are also involved in transmitting pain signals in the brain and nervous system. As pregabalin reduces the release of these neurotransmitters it can also be used to treat nerve pain occuring as a result of damage to or a disturbance in the function of nerves (neuropathic pain). It can be used for peripheral neuropathic pain, ie nerve pain in the hands, legs or feet, or central neuropathic pain, eg as a result of a spinal cord injury.
Pregabalin can also used to treat generalised anxiety disorder, which is another condition thought to involve overactivity of glutamate, substance P and noradrenaline in the brain.
What is it used for?
Epilepsy - used as an add-on therapy for adults with partial seizures with or without secondary generalisation.
Nerve pain (peripheral and central neuropathic pain) in adults, for example due to diabetic neuropathy, following shingles (post-herpetic neuralgia) or due to spinal cord injury.
Generalised anxiety disorder in adults.
How do I take it?
Lyrica capsules and oral solution can be taken either with or without food.
Lyrica capsules or oral solution are usually taken two to three times a day. The dose prescribed depends on the individual, the condition being treated and how well it is controlled. You should follow the instructions given by your doctor. These will also be printed on the dispensing label that your pharmacist has put on the medicine. Try to space your doses evenly over the day.
If you have epilepsy it is important to take your medication regularly, as directed by your doctor, because missing doses can trigger seizures in some people. If you have trouble remembering to take your medicine you should ask your pharmacist for advice. You may find a pill reminder box helpful.
You should not stop taking this medicine suddenly unless your doctor tells you otherwise, as this may result in your seizures, nerve pain or anxiety returning or getting worse.
