Diabetes and hypertension are the principal causes of death all over the world. Both diabetes and hypertension coexist frequently. Managing both is a multi-faced task requiring extensive care. Therapeutic intervention optimization and ensuring patient safety are the results of assessing medications in biological samples. The development of an analytical technique specific to the measurement of a medicinal chemical in a certain matrix requires careful consideration of the various equipment options and an understanding of their relative capabilities with regard to selectivity, sensitivity, usability, speed of investigation, etc. This article aimed to systematically analyze many popular quantitative analytical techniques for measuring some newly approved antidiabetic and antihypertensive drugs in pharmaceutical planning. Several chromatographic techniques have been employed for quantitative research into these pharmaceuticals. Rapid, accurate, cost-effective, and straightforward drug analysis methods are now essential for developing and using new technologies.
