MECHANISM OF ACTION
Tumor cells asserted epidermal growth factor receptors on their cell surface, present in both active and cancer infected cells. These receptors complicated in advancement of cell growth and production. Some epidermal growth factor receptors have exciting mutations (changes) within non small cell lung cancer cells which are supposing to encourage cancer cell growth, restrict the apoptosis, which may raise angiogenic factors and develop metastasis process. Geffyenclose Gefitinib causes erratic prohibition of tyrosine kinase and provoke abnormality of EGFR, block the autophosphorylation of tyrosine debris similar with receptor, via inhibition of following signaling and blockade EGFR dependent multiplication.
The usual prescribed dose of Lenalid in myelodysplastic syndromes is 10mg should be given as once a day. For renal damaged patients; In Patients with CrCl >60ml/min should not require dosage adjustment of Lenalid . In Patients with CrCl 30 to 60ml/min, 5mg of Lenalid should be given orally as once a day. In Patient with CrCl < 30ml/min, 2.5mg of Lenalid should be administered orally as a once a day.

Lenalid + digoxin, causes increased concentration of digoxin causes increased risk of adverse effects related to digoxin. Lenalid + Erythropoietic agents, leads to produced increased risk of thrombosis. Counsel the patients before starting this combination treatment. Lenalid + warfarin, causes increased exposure of bleeding disorders. Monitor the INR value & prothrombin time.
Lenalid should be contraindicated to pregnancy period. Hypersensitivity reactions are produced due to patients are contraindicated to the Lenalid component.
The most common life threatening condition like Embryo fetal damage Hypersensitivity reactions Venous & arterial thromboembolism Blood clotting effects Hematological disorders For all these conditions, some supportive measures should be used and provide safety measures.
PREGNANCY & LACTATION
Pregnancy category X Lenalid causes fetal damage leads to death Breast feeding should not be allowed
Lenalid capsules should be stored at 20°C to 25°C Protect the container from light Keep away from moisture & heat.
