Palliatives are defined as something that provides temporary relief or reduces the severity of a problem. The antonyms for palliatives are based on the opposite concept of providing permanent solutions instead of temporary relief. Therefore, the antonyms for palliatives include permanent solutions, cures, remedies, and treatments that aim to eliminate the problem or condition completely. Unlike palliatives, these antonyms focus on addressing the root cause of a problem rather than just alleviating the symptoms. These opposite words signify the importance of finding long-term solutions to problems rather than relying on temporary measures, which may not provide the desired results in the long run.
