Description
Evrysdi (Risdiplam uses)
Risdiplam is a survival of motor neuron 2 (SMN2) splicing modifier used for the treatment of spinal muscular atrophy (SMA) in patients aged 2 months and older.
Dosage: The recommended dose of Risdiplam is determined by age and body weight. The recommended daily dosage for patients aged 2 months to less than 2 years is 0.2 mg/kg, for patients aged 2 years and older weighing less than 20 kg is 0.25 mg/kg, and for patients aged 2 years and older weighing 20 kg or more is 5 mg. The risdiplam dosage is taken orally once daily after a meal at around the same time each day. Patients should drink water after taking Risdiplam to ensure the drug has been completely swallowed. In case the patient is not able to swallow and has a nasogastric or gastrostomy tube, Risdiplam can be administered via the tube. The tube must be flushed with water after delivering Risdiplam. In case a dose of Risdiplam is missed, it should be administered as soon as possible if still within six hours of the missed dose, and the usual dosing schedule can be resumed on the next day. Otherwise, the missed dose needs to be skipped, and the next dose should be administered at the regularly scheduled time on the next day.
