Strictly speaking that’s what palliate means, but palliative care almost always refers to symptomatic care for people with life threatening conditions (see the WHO definition[0]). If you look at the way the phrase is most often used in medical literature, you can see it’s qualitatively different from general symptomatic treatment, as the potential side effects are assessed differently. You’d be much less concerned about a patient developing an opioid dependence if they’re terminally ill. For instance the standard[1] from BC describing guidelines for opiate prescriptions states:
> This standard does not apply to active cancer care, palliative care, and management of substance use disorders. Physicians are expected to follow relevant clinical guidelines and established best practices in managing patients with these conditions. Nothing in this standard interferes with a physician’s obligation to provide aggressive symptom management to patients with active cancer, or nearing the end of their lives.
> is applicable early in the course of illness, in conjunction with other therapies that are intended to prolong life, such as chemotherapy or radiation therapy, and includes those investigations needed to better understand and manage distressing clinical complications.
> Palliative care can be given at the same time as treatments meant to cure or treat the disease. Palliative care may be given when the illness is diagnosed, throughout treatment, during follow-up, and at the end of life.
> Doctors can provide treatment to seriously ill patients in the hopes of a cure for as long as possible. These patients may also receive medical care for their symptoms, or palliative care, along with curative treatment.
But, this is an aside. When we're talking about any given treatment medication / treatment-- it can be a likely cure; it can halt or slow the progression of the disease itself; it can merely provide symptom relief. The latter is often called a palliative.
> it can merely provide symptom relief. The latter is often called a palliative.
Because some times it is, but sometimes it isn’t. Which is why the document I linked detailing prescription guidelines for opioids (medicines which exclusively treat symptoms), specifically states that the guidelines do not apply to palliative care. If all treatment of symptoms was palliative treatment, then that standard would never apply in any situation.
