Inavolisib
Inavolisib, sold under the brand name Itovebi, is an anti-cancer medication used for the treatment of breast cancer. It is a inhibitor and degrader of mutant phosphatidylinositol 3-kinase (PI3K) alpha. The PI3K-mediated signalling pathway has shown to play an important role in the development of tumours as dysregulation is commonly associated with tumour growth and resistance to antineoplastic agents and radiotherapy. The most common adverse reactions include decreased neutrophils, decreased hemoglobin, increased fasting glucose, decreased platelets, decreased lymphocytes, stomatitis, diarrhea, decreased calcium, fatigue, decreased potassium, increased creatinine, increased ALT, nausea, decreased sodium, decreased magnesium, rash, decreased appetite, COVID-19 infection, and headache. Inavolisib was approved by the US Food and Drug Administration (FDA) for treatment of PIK3CA-mutant breast cancer in October 2024. Medical uses Inavolisib is indicated in combination with pa ...

PI3K Inhibitor
Phosphoinositide 3-kinase inhibitors (PI3K inhibitors) are a class of medical drugs that are mainly used to treat advanced cancers. They function by inhibiting one or more of the phosphoinositide 3-kinase (PI3K) enzymes, which are part of the PI3K/AKT/mTOR pathway. This signal pathway regulates cellular functions such as growth and survival. It is strictly regulated in healthy cells, but is always active in many cancer cells, allowing the cancer cells to better survive and multiply. PI3K inhibitors block the PI3K/AKT/mTOR pathway and thus slow down cancer growth. They are examples of a targeted therapy. While PI3K inhibitors are an effective treatment, they can have very severe side effects and are therefore only used if other treatments have failed or are not suitable. After PI3K inhibitors had been under investigation as anti-cancer drugs for several years, the first one to be approved for treatment in clinical practice was idelalisib in 2014. Several others followed, and even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
By Mouth
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
