Crisugabalin is a twice-a-day capsule for long-lasting nerve pain. It was discovered and developed in China by Haisco Pharmaceutical Group, where it is sold as 思美宁® and was known in trials by the code HSK16149.
China's National Medical Products Administration (NMPA) approved it in May 2024, and the current Chinese label covers adults with:
It is a prescription neurology medicine and should be started and reviewed by a neurologist, pain specialist, diabetologist or dermatologist.
Crisugabalin is built on the shape of GABA, one of the brain's natural calming messengers, but it does not act on GABA receptors themselves. Instead, it attaches to a part of the calcium channels on over-active pain nerves known as the alpha-2-delta subunit. The label is honest that its exact mechanism is not fully understood. In practice, it quietens the faulty pain signals that damaged nerves keep sending.
Diabetic nerve pain: a phase 2/3 trial in China, published in JAMA Network Open in 2024, treated patients for 13 weeks. Average daily pain scores (0 to 10) fell by 2.24 points on 20 mg twice daily and 2.16 points on 40 mg twice daily, against 1.23 points on placebo. More than half of patients on the lower dose (57.3%) had their pain cut by at least 30%, compared with 31.6% on placebo.
Post-shingles nerve pain: a phase 3 trial of 366 adults, published in JAMA Dermatology in 2024, ran for 12 weeks. Pain scores fell by about 2.3 points on 20 mg twice daily and 2.5 points on 40 mg twice daily, against about 1.0 point on placebo. At least a 30% drop in pain was seen in 61.2% and 54.5% of patients on the two doses, compared with 35.5% on placebo.
According to the Chinese label, it can be taken with or without food:
Side effects rise with dose, so your doctor will use the lowest dose that controls the pain.
This information is not a treatment plan. For personalized medical advice, consult your doctor and refer to the full prescribing information.
Dizziness and sleepiness: these are the main side effects. Across the two controlled trials, dizziness affected 22.7% of people on crisugabalin against 5.7% on placebo, and sleepiness 7.5% against 0.3%. About 8 in 10 of these episodes began in the first week, and almost all were mild to moderate. Do not drive or use machines until you know how it affects you.
Stopping because of side effects: 5.1% of patients in the diabetic nerve pain trial (placebo 1.1%) and 2.0% in the post-shingles trial (placebo 0%). It is not recommended in pregnancy or breastfeeding, and safety in under-18s has not been established.
