A term used to describe a medicine that has effects throughout the body, as opposed to topical drugs that work on the skin. Most medicines that are taken by mouth or by injection are systemic drugs.

systemic

(1) relating to a system as a whole, e.g. with reference to pathological conditions, affecting the whole body, as opposed to being localized; (2) with reference to the circulation of the blood, the route from the left side of the heart through the vessels supplying the whole body except the lungs, and returning to the right side of the heart.

systemic

body-wide effects of a specific disease, or a drug (Table 1)
Table 1: Long-term systemic medication in the perioperative period
Systemic drugEffects of sudden withdrawal of long-term medication
CorticosteroidLong-term corticosteroid therapy (including high-dose inhaled corticosteroid) leads to adrenal atrophy
Patients will show a precipitous fall in blood pressure if systemic corticosteroids are suddenly withdrawn
Patients may require an increased dose of systemic steroid during the perioperative period
Antiepileptic
Antiparkinsonian drugs
Antipsychotics
Anxiolytics
Bronchodilators
Cardiovascular drugs
Glaucoma drugs
Immunosuppressants
Thyroid supplements
The sudden withdrawal of these drugs will lead to breakthrough of the underlying disease state.
Thus their use should be continued during the perioperative period
Anticoagulants (aspirin, warfarin)Anticoagulant therapy is usually maintained during the perioperative period, using low-molecular-weight heparin, e.g. Fragmin). Surgery is preceded by 4 days without warfarin, with 48 hours of subcuticular heparin immediately before surgery. The warfarin regimen is usually restarted on the day of, or the day after, surgery, whilst continuing to use heparin. Heparin therapy is usually discontinued 4-7 days after surgery and the patient maintained on warfarin therapy with early post-operative INR monitoring
Combined oral contraceptives
Hormone replacement therapy
As these drugs predispose to venous thrombosis, they are usually stopped for the perioperative period
AntidepressantsThese drugs are gradually withdrawn in the presurgery period (to avoid withdrawal symptoms) and resumed postsurgically, as necessary
Monoamine oxidase inhibitors (MAOIs)In order to avoid potential drug interactions with medications that may be used in the perioperative period, MAOIs should be withdrawn 2 weeks before surgery
Tricyclic antidepressantsThese are usually maintained during the perioperative period, but patients may show arrhythmias or hypotension
Lithium carbonateThis should be stopped 24 hours before major surgery
It may be continued throughout minor surgery, but fluids and electrolytes should be monitored
Potassium-sparing diureticsWithheld on the day of surgery (patients may develop hyperkalaemia if renal perfusion becomes impaired or tissue is damaged during surgery)

systemic

pertaining to or affecting the body as a whole.

systemic inflammatory response (SIR)
a specific condition recognized in critical care medicine, characterized by febrile response, increased heart and respiratory rates, and leukocytosis.
systemic lupus erythematosus
systemic neuroaxial dystrophy
systemic therapy
treatment with a drug that is absorbed into the bloodstream and distributed to all parts of the body except where there is a specific barrier.

A. here is a quote from the National Fibromyalgia Association site:

"Little research has been conducted that measures the prevalence of fibromyalgia, and estimates vary widely as to the proportion of male versus female patients. A 1999 epidemiology study conducted in London found a female to male ratio of roughly three to one. However, a 2001 review of the research literature in Current Rheumatology Reports stated the ratio was nine to one."
