(BPT) - Jim, an 81-year-old former lawyer who lives in Sarasota, Florida, was in Aruba on vacation in the late 1970s when he first experienced an uncomfortable feeling in his legs, almost like shocks.

'It was an alarming sensation, and I had no clue what it was at the time,' Jim said.

It took decades for Jim to be diagnosed with Restless Legs Syndrome (RLS), a sleep-related movement disorder characterized by an urge to move one or both legs, which may be relieved by movement and is most prominent at night.ⁱ

RLS can cause an irresistible urge to move one's legs, a feeling of anticipation and often disrupts the ability to get a good night's sleep. Clinically significant RLS impacts 2-3 percent of adults in the United States.ⁱⁱ

'From my experience treating patients diagnosed with RLS, their complaints are severe sleep disturbance, daytime fatigue, and mood changes, which can dramatically impair quality of life,' states John Winkelman, M.D., Ph.D., chief of the Sleep Disorders Clinical Research Program in the Department of Psychiatry at Massachusetts General Hospital.

Thirty years after his initial symptoms, following countless visits to the doctor's office, and trying different medications that didn't work but instead caused bothersome side effects, Jim was diagnosed with RLS by a sleep medicine physician.

Jim tried several treatment regimens before he was prescribed one which included Horizant^® (gabapentin enacarbil) that made his symptoms better.* His constant need to get up and move and stretch throughout the night is now behind him.** Gabapentin enacarbil (Horizant^®) extended-release tablets are indicated for the treatment of moderate-to-severe primary RLS in adults. Horizant is not recommended for patients who are required to sleep during the daytime and remain awake at night.ⁱⁱⁱ

American Academy of Sleep Medicine (AASM) updates its Clinical Practice Guidelines for RLS

For the first time since 2012, the American Academy of Sleep Medicine (AASM) issued an update to its Clinical Practice Guidelines for the treatment of RLS, which provide physicians with recommended treatment options based on a review of the latest clinical research. Dopamine agonists (DAs) have been widely used for the treatment of RLS for 20 years. AASM Clinical Practice Guidelines now suggest against the standard use of DAs due to the risk of augmentation (a gradual worsening of RLS symptom intensity and duration) of RLS symptoms.^iv

'Increasing clinical research has demonstrated that dopamine agonists are often associated with a long-term overall worsening of RLS symptoms and are no longer recommended,' Winkelman said. 'Gabapentin, gabapentin enacarbil, pregabalin and iron treatment are strongly recommended for the treatment of RLS and it's important that everyone - physicians and patients - are aware of these changes.'

Gabapentin enacarbil (Horizant^®) is the only strongly recommended FDA-approved RLS treatment providing clinically significant improvement in all three of these key domains: RLS disease severity, sleep quality, and quality of life.^iv

The importance of talking to a physician about treatment options

It's important for doctors and people diagnosed suffering from RLS to be aware of these updated guidelines for this widely used class of drugs. Those taking dopamine agonists should speak with their doctor about their current treatment plan.

Jim can now sleep soundly without the need to get up and stretch thanks to his current treatment regimen. Those with RLS who are not finding relief from their current regimen should speak with their doctor to discuss their treatment plan.

* The most common adverse reactions for patients with RLS (incidence >10% and at least 2 times the rate of placebo) were somnolence/sedation and dizziness.

**Strong recommendation, moderate certainty of evidence; based on 8 randomized controlled trials and 3 observational studies.

Important Safety Information for HORIZANT^® (gabapentin enacarbil) Extended-Release Tablets

INDICATIONS

HORIZANT^® (gabapentin enacarbil) is a prescription medicine used to:

• treat adults with moderate to severe primary Restless Legs Syndrome (RLS). HORIZANT is not for people who need to sleep during the daytime and stay awake at night.
• manage pain from damaged nerves (postherpetic neuralgia) that follows healing of shingles (a painful rash that comes after a herpes zoster infection) in adults.

IMPORTANT SAFETY INFORMATION

• Do not drive after taking your dose of HORIZANT until you know how it affects you, including the morning after you take it. Do not operate heavy machinery or do other dangerous activities until you know how HORIZANT affects you. HORIZANT can cause sleepiness, dizziness, slow thinking, and can affect your coordination. Ask your healthcare provider when it is okay to do these activities.
• Do not take other medicines that make you sleepy or dizzy while taking HORIZANT without talking to your healthcare provider. Taking HORIZANT with these other medicines may make your sleepiness or dizziness worse.
• HORIZANT may cause suicidal thoughts or actions in a very small number of people (about 1 in 500). Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. Call your healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:
  • thoughts or actions about suicide, self-harm, or dying; attempt to commit suicide
  • new or worsening depression or anxiety; or feeling agitated
  • new or worse restlessness or panic attacks
  • new or worse trouble sleeping (insomnia); or irritability
  • acting aggressive, being angry, or violent; acting on dangerous impulses
  • an extreme increase in activity or talking (mania); other unusual changes in mood or behavior
• Serious breathing problems. Serious breathing problems can occur when HORIZANT is taken with other medicines that can cause severe sleepiness or decreased awareness, or when it is taken by someone who already has breathing problems. Watch for increased sleepiness or decreased breathing when starting HORIZANT or when the dose is increased. Get help right away if breathing problems occur.
• Do not stop taking HORIZANT without first talking to your healthcare provider. Suicidal thoughts or actions can be caused by things other than medicines. If you have these thoughts or actions, your healthcare provider may check for other causes.
• HORIZANT may cause a serious or life-threatening allergic reaction that may affect your skin or other parts of your body such as your liver or blood cells. You may or may not have a rash with these types of reactions. Call a healthcare provider right away if you have any of the following symptoms: skin rash, hives, fever, swollen glands that do not go away, swelling of your lips or tongue, yellowing of your skin or eyes, unusual bruising or bleeding, severe fatigue or weakness, unexpected severe muscle pain, or frequent infections. These symptoms may be the first signs of a serious reaction. A healthcare provider should examine you to decide if you should continue taking HORIZANT.
• HORIZANT is not the same medicine as gabapentin [for example, NEURONTIN^® (gabapentin) and GRALISE^® (gabapentin)]. HORIZANT should not be used in their place. Do not take these or other gabapentin products while taking HORIZANT.
• Before taking HORIZANT, tell your healthcare provider if you:
  • have or have had kidney problems or are on hemodialysis
  • have or have had depression, mood problems, or suicidal thoughts or behavior
  • have or have had seizures
  • have a history of drug abuse
  • have any other medical conditions
  • are pregnant or plan to become pregnant. It is not known if HORIZANT will harm your unborn baby. Talk to your healthcare provider if you are pregnant or plan to become pregnant while taking HORIZANT. You and your healthcare provider will decide if you should take HORIZANT while you are pregnant
  • are breastfeeding or plan to breastfeed. Your body turns HORIZANT into another drug (gabapentin) that passes into your milk. It is not known if this can harm your baby. You and your healthcare provider should decide if you will take HORIZANT or breastfeed
  • drink alcohol
• Do not drink alcohol while taking HORIZANT because it may increase the risk of side effects.
• Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Taking HORIZANT with certain other medicines can cause side effects or affect how well they work. Do not start or stop other medicines without talking to your healthcare provider.
• Do not stop taking HORIZANT without talking to your healthcare provider first. If you stop taking HORIZANT suddenly, you may develop side effects.
• The most common side effects of HORIZANT include dizziness, sleepiness, and headache. Tell your healthcare provider about any side effect that bothers you or does not go away. These are not all the possible side effects of HORIZANT. For more information, ask your healthcare provider or pharmacist.
