How long can I take a box of Sotorasib?

Sotorasib is a targeted drug targeting the KRAS G12C mutation and is suitable for the treatment of some patients with non-small cell lung cancer (NSCLC) and other malignant tumors. Before formal use of the drug, patients should determine whether they have the KRAS G12C mutation and take it under the guidance of a doctor. Many patients are concerned about a practical question when using sotorasiib: How long can a box of pills last? This mainly depends on the drug strength, recommended dosage and individual patient treatment plan.

First of all, from the recommended dose point of view, the standard dose of sotoraxib is 960mgonce a day, usually in the form of 120mg tablets taken 8tables/days. According to this method of taking medicine, if a box of medicine is packaged in 120mg×240 tablets (this is a common specification), then a box of medicine can be used by the patient for a full 30 days, which is a complete treatment cycle. This course of treatment can be regarded as a starting point for the patient's disease to be under stable control, but it does not mean that the drug can be stopped after 30 days. The actual treatment period is often longer.

Secondly, in some cases, patients may need doctors to adjust the dose due to adverse reactions (such as abnormal liver function, gastrointestinal reactions or fatigue, etc.), such as reducing to 720mg or 480mg per day. In this case of reducing the dosage, the use time of a box of drugs will naturally be extended. For example, if you take 6 tablets (720mg) every day, a box of 240 tablets can take about 40days; if it is reduced to 480mg (4 tablets/days), you can take a full 60 days. In other words, after the dosage is halved, a box of medicine can be used for twice as long, but whether to reduce the dosage must be decided by the doctor based on the patient's tolerance and treatment response.

In addition, it should be noted that sotorasiib is a maintenance treatment drug that needs to be taken long-term, and patients generally need to continue taking it until the disease progresses or intolerable side effects occur. Therefore, regular imaging and blood tests are required while taking the drug to monitor the effectiveness of the treatment. A box of medicine is not the end point of a complete course of treatment, but a phased medication unit. Most patients will use multiple boxes of medicine continuously and refill on time every month.
