selective serotonin reuptake inhibitors (SSRIs)
A selective serotonin reuptake inhibitor (SSRI) is one of the commonly prescribed drugs for treating depression. SSRIs affect the chemicals that nerves in the brain use to send messages to one another. Neurotransmitters that are not taken up by other nerves are taken up by the same nerves that released them. This process is termed "reuptake." SSRIs work by inhibiting the reuptake of serotonin, an action which allows more serotonin to be available to be taken up by other nerves.

Chronic Granulomatous disease
usually due to X-linked mutation in NADPH oxidase. Deficiency results in an inability to form the oxidative burst in neutorphils results in infection with Catalase positive organisms Dx can occur by either ntiroblue tetrazolium test negativity or dihydrorhodamine flow cytometry

Nitrates
via conversion to NO activate guanylate cyclase and increase intracellular levels of cGMP, which leads to decreased activity of myosin light chain kinase (less calcium), thus leading to mysoin light chain dephosphorylation, resulting in vascular smooth muscle relaxation. Often used during a hypertensive crisis.

mechanism of action (MOA)
way that a drug produces a therapeutic effect. There are many different ways that a drug work
additive effect
when 2 drugs with similar actions are giving together and allows a more therapeutic effect with fewer side effects due to smaller doses of each drug. opioid & non-opioid, anti hypertensive with diuretic
interactions
when the action of one drug is affected by the action of another drug, As number of drugs taken at one time increase, the risk of interaction also increase
therapeutic index/range
when the amount of the drug in the plasma is above the minimum effective concentration (MEC) and below the toxic concentration. Some drugs have a narrow therapeutic range like lithium
