Imatinib therapy has revolutionized the treatment of patients with gastrointestinal stromal tumors (GISTs). Compared with older therapy, imatinib significantly improves outcomes in patients with metastatic disease and those with locally advanced tumors, raising progression-free and overall survival. Recent studies have evaluated variables such as timing of treatment, total dosing, and duration of therapy. Different genotypes are associated with a poorer response to imatinib therapy, whereas others may benefit from a higher starting dose. This review discusses recent data regarding optimal use of imatinib for treatment of GIST in both the adjuvant and metastatic settings, and addresses topics such as the impact of genotype on initial dose, dose escalation, optimal duration of treatment, and neoadjuvant therapy. Key ongoing clinical trials of imatinib in GIST are also discussed.

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...
