“…In a recent demonstration of this in 142 691 patients with bipolar disorder, schizophrenia, or nonaffective psychosis, exposure to hydroxylmethyl glutaryl coenzyme A reductase inhibitors (statins, used to reduce cholesterol and heart disease), L-type calcium channel antagonists (used to reduce blood pressure), and biguanides (used to treat diabetes) were all associated with reduced rates of psychiatric hospitalisation, and in some cases reduced rates of self-harm compared with unexposed periods [93]. These effects may be due to modulation of key physiological systems, for example, statins have anti-inflammatory effects on levels of IL-1β, IL-6, tumour necrosis factor, and CRP [18,19,[93][94][95] in addition to significant effects on the cardiovascular system.…”
