Availability of Seleniso in Paraguay and its treatment mechanisms

Currently, according to available information, no original or generic version of Selinexor (Selinexor) is produced in Paraguay. However, this does not mean that the drug cannot be purchased in Paraguay. In fact, Seleniso's original drug may already be sold in Paraguay and other places. This drug is produced by Karyopharm Therapeutics Inc. and has been launched in the United States, China, the European Union, Canada and other regions. In addition, generic drugs of selinesol have also appeared on the market, and their drug ingredients are highly similar to the original drug.

Selinesol, an innovative selective inhibitor of nuclear export (SINE) XPO1 antagonist, provides a new treatment option for adult patients with relapsed or refractory multiple myeloma (RRMM) and diffuse large B-cell lymphoma (DLBCL). Like other SINEs, selinesol works by binding to and inhibiting exportin 1 (also known as XPO1 or CRM1). XPO1 is a nuclear protein that is frequently overexpressed and dysfunctional in a variety of cancers and is responsible for transporting a variety of key proteins from the nucleus to the cytoplasm. By inhibiting the function of the XPO1 protein, SINEs drugs can cause the accumulation of tumor suppressors in the nuclei of malignant cells and reduce the levels of oncogene products that drive cell proliferation. This mechanism of action ultimately induces cancer cell cycle arrest and leads to cancer cell death through the process of apoptosis.

For patients who need to buy selinesol, it is very important to understand the sales and price differences of the drug in different regions. For the domestic market, each box of the original Seleniso drug may exceed RMB 20,000. In overseas markets, for example, the US version of the original drug is more expensive. Each box (specification: 20 mg 8 tablets) may cost more than 100,000 yuan, and the price may change due to exchange rate fluctuations. In comparison, the price of generic selinexol drugs produced by Lao pharmaceutical factories is relatively affordable. Each box (specification: 20 mg and 32 tablets) may be around 2,000 yuan, but the price may also fluctuate due to the exchange rate.
