The Benefits and Disadvantages of Dasatinib


There are a few things to know about dasatinib before you start taking it. The drug has been shown to prolong the QT interval and cardiac ventricular repolarization and has been associated with fewer side effects, including cytopenia and pleural effusions. In addition, dasatinib increases p-CrKL levels after 8 hours. But it also has some disadvantages.

Dasatinib is associated with a reduced incidence of cytopenia and pleural effusions

In clinical studies, dasatinib was associated with a significantly reduced incidence of pleural effusion, with a correspondingly lower risk of recurrence. Incidences were highest in patients who did not discontinue the drug immediately. In the relapsed group, the rate of recurrence was three times higher than in those who continued treatment with dasatinib.

One study found that dasatinib was associated with a grade three bleeding risk in CML-CP patients. This was due to dasatinib-induced platelet dysfunction. Specifically, 4 of seven clinically significant bleeding events occurred in patients with moderate or severe thrombocytopenia, including 1 patient taking aspirin. The other two patients had normal platelet counts. This study was not affected by concomitant thrombotic or anti-platelet therapy.

The researchers also reported that dasatinib is associated with a decreased incidence of pleural effusions and cytopenia in patients who had already had chemotherapy. However, there are some limitations to the findings. In the study, the lowest effective dose was used to reduce the risk of effusion in elderly patients. In addition, dasatinib is safe for patients on concomitant antiplatelet therapy.

Moreover, the risk of pleural effusion is also increased in patients with preexisting comorbidities, such as infection, viral reactivation, or activated lymphocytes. Patients on dasatinib should be monitored closely for any signs of fluid retention or pleural effusion, as well as the use of supportive measures.


It prolongs QT interval

Anticancer drugs such as Dasatinib may prolong the QT interval. Long QT intervals can lead to fatal polymorphic ventricular tachycardia, a type of heart rhythm disorder. Drugs that prolong the QT interval include anthracyclines and arsenic trioxides, and novel molecular-targeted agents. The risk of TdP may also be increased by factors that affect myocardial repolarization. In this article, we will review the QT toxicity of some of the most common anticancer drugs, and how to minimize it in high-risk patients. In particular, we will discuss how QT toxicity and bradycardia are associated with increased mortality in patients who are at risk.

While the risk of QT interval prolongation is low, it should be kept in mind when prescribing other drugs. While the risk of QT prolongation is small, patients should be closely monitored for any changes in the QT interval. Any change in QT interval should prompt removal of other treatments. Additionally, pharmacists should monitor the clearance of all QT prolonging drugs, as reduced liver and renal function can increase the risks of prolonged QT.

Although there are no definitive studies, the FDA approved TKIs for certain situations. Imatinib has already been approved for localised GIST, and other tumour types are under investigation. Until such a time, further studies are needed to assess the cardiovascular safety of these drugs. In the meantime, the results of a multicentre study conducted in four centres in the Netherlands and Italy examined whether dasatinib prolongs the QTc interval in patients with cancer.

It prolongs cardiac ventricular repolarization

There is a growing body of evidence that dasatinib prolongs cardiac ventricular function. While it has shown a good safety profile, dasatinib is also associated with some risk of ventricular arrhythmias. In five Phase 2 single-arm studies, 865 patients were treated with Sprycel. Of these, 22 patients experienced a QTc prolongation of at least 500 ms. QTcF changes ranged from 7.0 to 13.4 ms.

In addition to the safety risks of dasatinib, a major concern with the drug is the possibility of fetal harm from the drug. Pregnancy should be avoided in female patients receiving dasatinib, and pregnant women should seek immediate medical attention if they become pregnant. The drug is not approved for patients with immunosuppression or other conditions that impair repolarization of the heart. In addition, there is limited information regarding IV compatibility with other drugs, and overdoses have been reported only in isolated cases.

It is important to understand that dasatinib is mostly eliminated from the body through the urine and feces. It has been reported to cause fetal bicytopenia and hydrops fetalis when administered to pregnant rats. Moreover, it has been reported that the drug can cause fetal mortality. However, these adverse effects have been reported in small doses and at low exposures.

It prolongs p-CrKL after 8 h

The study found that dasatinib reduced CD56+ T-cell recovery, but did not affect ILC3 cells, which produce IL-22. The mechanism of action of dasatinib is thought to involve indirect STAT5-signaling activation in CD34+ cells and inhibition of Src kinases. Furthermore, the drug interfered with the proliferation of fully competent NK cells and may disrupt signaling pathways important for NK cell differentiation and survival.

The study also confirmed that intermittent BCR-ABL inhibition is efficacious. It also evaluated the toxicity of two total daily doses, and investigated the potential clinical utility of intermittent BCR-ABL inhibition. The study was conducted in accordance with the Declaration of Helsinki and was approved by local ethical committees. These findings support the potential of dasatinib for use in the treatment of patients with CML.

It is important to note, however, that the effectiveness of dasatinib should be studied carefully. In this way, it can help physicians predict when enough Cmax is needed to treat a patient’s condition.

It prolongs p-CrKL after 8 h in patients with CML-AP

In a recent study, dasatinib significantly prolonged p-CrKL levels after 8 h in patients with CML. It also extended p-CrKL in late AP patients, including those who were treated for years with CP. These results, however, may be affected by differences in patient selection criteria or definitions of AP-CML.

Advancement in CML is accompanied by growing genomic instability. To combat this, novel drugs are being tested in combination. One such candidate is dasatinib, which prolongs p-CrKL after eight hours in patients with CML-AP. Its efficacy depends on the duration of treatment, but it has already shown an encouraging impact in reducing progressions on existing therapy.

In addition, dasatinib is approved for use in AIDS and CML-AP. In two Phase III trials, dasatinib was found to prolong p-CrKL after eight hours in patients with CML-AP. However, dasatinib does have some risks. Dasatinib is associated with a high rate of cardiac adverse events, including cardiomyopathy, QT-prolongation, and diastolic dysfunction. Furthermore, it causes skin sequelae, including exfoliation, pigmentation disorder, and ulcers.

Another potential drug for CML-AP is imatinib. Imatinib prolongs p-CrKL after eight hours. It may also extend the time it takes for p-CrKL to become undetectable. The mechanism for this is still not clear, but scientists do know that dasatinib prolongs p-CrKL after eight hours in patients with CML-AP.
