I interested with the anticancer properties of artesunate, which in my case is for breast cancer therapy. While artesunate is known for using as i.v. injection, could artesunate also be formulated as i.m. injection? Since breast tissue is rich with lipid I would like to develop i.m. injection of artesunate which injected directly to breast tissue with cancer in hope that artesunate injected would be more distributed at breast tissue.
