Clinical pharmacy services aim to ensure the rational use of drugs and resolve disease/health conditions with a multidisciplinary approach. Pharmaceutical care plans need to be created to effectively provide clinical pharmacy services in the treatment of hypertension which is one of the common chronic diseases in cancer patients. In this mini-review, we examine which drugs can cause or worsen hypertension in patients receiving cancer treatment, potential drug-drug interactions between drugs used in cancer treatment and antihypertensive drugs, pharmacological and clinical studies for the treatment of hypertension in patients with hypertension before cancer diagnosis or newly diagnosed hypertension due to cancer treatment. Non-pharmacological treatment approaches are presented. We think that our study will be a resource that can be used to solve possible drug-related problems in the practice.
