Top brand choice
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Kisqali, scientifically known as Ribociclib, marks a significant advancement in the field of oncology, particularly in the treatment of certain types of breast cancer. Kisqali is a selective inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6), enzymes crucial for cell division. By inhibiting these kinases, Kisqali effectively halts the proliferation of cancer cells, thereby impeding tumor growth. The medication is specifically designed for postmenopausal women and men diagnosed with HR+/HER2- advanced or metastatic breast cancer as an initial endocrine-based therapy or following disease progression on endocrine therapy.
Before you buy Kisqali, it is crucial that you talk to your healthcare provider about potential side effects and Kisqali cost.

Kisqali is administered orally, with dosages typically ranging from 600 mg taken once daily for 21 consecutive days to 600 mg taken once daily for seven consecutive days, followed by a 7-day rest period, constituting a complete 28-day cycle. This regimen is often combined with an aromatase inhibitor or fulvestrant, depending on the patient's specific treatment history and disease progression. Patients are advised to take Kisqali at approximately the same time each day, with or without food. Swallow the tablets whole; do not chew, crush, or split them.
Kisqali uses Ribociclib as its active ingredient.
Before starting Kisqali, patients should discuss their entire medical history with their healthcare provider, especially any history of heart disease, liver problems, or long QT syndrome.
Regular monitoring of blood counts and liver function tests is recommended to detect potential adverse effects early.
Kisqali can cause fetal harm; therefore, women of childbearing potential should use effective contraception during treatment and for at least three weeks after the last dose. Breastfeeding is not recommended during treatment and for at least three weeks following the previous dose of Kisqali.
Kisqali can interact with various medications, potentially affecting its efficacy or increasing the risk of adverse effects. These interactions may include, but are not limited to, strong CYP3A inhibitors or inducers, which can significantly alter Ribociclib plasma concentrations. Patients should inform their healthcare provider of all medications, supplements, and herbal products they are currently taking to avoid harmful interactions.
While Kisqali is a targeted therapy designed to minimize harm to healthy cells, side effects can occur.
Common side effects include:
