Nintedanib administration time
The administration time of Nidanib should strictly follow the dosing regimen of twice a day with an interval of about 12 hours. It is recommended to take it with meals to improve drug absorption rate. If missed, there is no need to supplement, but regular medication intervals should be maintained.
1. Standard administration time
(1) Frequency requirement: Take orally twice a day at a fixed time (such as 8am and 8pm) to maintain a stable blood drug concentration.
(2) Interval control: Two doses should be administered approximately 12 hours apart to avoid excessive fluctuations in blood drug concentration.
2. Relationship with Eating
(1) Take with meals: The capsule should be swallowed whole with meals, as food can increase drug exposure by about 20%.
(2) Absorption characteristics: Peak blood drug concentration is reached 2-4 hours after meals, and taking on an empty stomach may reduce bioavailability.
3. Handling of special circumstances
(1) Principle of missed doses: If missed doses are found, there is no need to supplement them. The next dose should be taken according to the original plan to avoid double doses.
(2) Dose adjustment: For patients with liver dysfunction, it should be adjusted to 100mg twice a day, and it is contraindicated for those with moderate to severe liver dysfunction.
4. Duration of medication
(1) Treatment cycle: Long term continuous medication is required until disease progression or intolerance occurs, and the drug is effective for 24 months.
(2) Indications for discontinuation of medication: Permanent discontinuation of medication is required when severe liver damage such as AST/ALT>5 times the normal value occurs.
