Can cabozantinib be taken for 5 days and stopped for 2 days?

Cabozantinib (Cabozantinib) is a prescription drug that needs to be used under the guidance of a doctor. If you need to use cabozantinib, be sure to follow your doctor's advice and do not change the medication regimen at will, including whether to take it for 5 days and stop for 2 days. This may cause the tumor to adapt to the drug and develop resistance. This is because cabozantinib needs to maintain a stable concentration of the drug in the body in order to better exert its therapeutic effect.

The recommended dose of cabozantinib is140 mg once daily (one 80 mg and three 20 mg capsules). These capsules should not be taken with food, and patients should not eat for at least 2 hours before and 1 hour after taking cabozantinib. Treatment can be continued until disease progression or unacceptable toxicity occurs. Capsules should be swallowed whole and not opened. A missed dose should not be taken within 12 hours of the next dose. During treatment with cabozantinib, patients should not consume foods known to inhibit cytochrome P450 (cyp450) (such as grapefruit or grapefruit juice) or nutritional supplements.

The original drug Cabozantinib is not marketed in the country and therefore cannot be included in medical insurance. The original cabozantinib drug marketed overseas includes Japanese, Turkish and European versions. The price of tablets may be more than 30,000 yuan, and the price of capsule preparations may be more than 40,000 yuan (prices may fluctuate due to exchange rates). There are also generic drugs produced in other countries overseas, and their pharmaceutical ingredients are basically the same as those of the original drugs. For example, the price of pharmaceuticals produced by Bangladeshi pharmaceutical factories may be more than 2,000 yuan (the price may fluctuate due to the exchange rate), which is relatively cheap.
