Who is Selpercatinib suitable for?

Patients should have a detailed understanding of the indications of the drug before choosing to be treated with Selpercatinib.

1. Cholangiocarcinoma

Selpercatinib is indicated for the treatment of previously treated, inoperable locally advanced or metastatic cholangiocarcinoma, particularly those where fibroblast growth factor receptor 2 (FGFR2) fusions or other FDA-approved rearrangements have been detected.

What is the dosage of Selpercatinib?

It is important for doctors and patients to know the dosage and dosage of the drug, according to the drug label:

Dose adjustment when used concomitantly with strong or moderate CYP3A inhibitors

Avoid concomitant use of strong or moderate CYP3A inhibitors with Selpercatinib. If you can't avoid it:

The dose of Selpercatinib was reduced from 13.5mg to 9mg, and the dose of Selpercatinib was reduced from 9mg to 4.5mg.

If a strong or moderate CYP3A inhibitor is discontinued, the dose of Selpercatinib should be restored to the level prior to initiation of the inhibitor after 3 plasma half-lives of the CYP3A inhibitor have been discontinued.

What are the possible adverse reactions of Selpercatinib when taking it?

Adverse drug reactions that may occur during the use of Selpercatinib include, but are not limited to, the following.

1. Vomiting

Frequent vomiting can lead to dehydration and electrolyte imbalances, further aggravating the patient's discomfort. To relieve vomiting symptoms, your doctor may prescribe anti-vomiting medications and advise you to eat small, frequent meals and avoid irritating foods.

2. Arthralgia

Pain in the joints may affect the patient's range of motion and daily life. To alleviate joint pain, patients can use painkillers and exercise appropriately to keep their joints flexible.
