…but does not lower potassium by a tenth of a millimole. Insulin-glucose, beta-agonists, and dialysis must be started in parallel, otherwise the arrhythmia…

Dobutamin Hameln Synthetic catecholamine, β₁-agonist (inotropy) Pure inotropy when the problem is the pump and not vascular tone. Strong β₁ effect with marked β₂…

…The dose–response relationship is a threshold curve, not a line: below the threshold nothing happens, and in renal failure the threshold dose must be…

…both therapeutic for reentry involving the node and diagnostic for arrhythmias that do not — atrial flutter and atrial tachycardia are unmasked when the ventricular response…

…cardiac arrest treatment. The most clinically dangerous property is not pharmacological but practical: two concentrations with a tenfold difference are used in the same setting.

…gout, with the goal of titrating upward until serum urate is stably below 360 μmol/l — not setting a fixed dose and leaving it…

…already at 10–50 mg and depends on noradrenergic and sodium-channel-mediated modulation, not on antidepressant action. What limits treatment is anticholinergic side effects…

…determines its use. Amoxicillin is therefore not first-line for uncomplicated acute otitis media — that role belongs to phenoxymethylpenicillin — but for treatment failure, recurrent otitis…

…the blood-brain barrier poorly, but it is not entirely free of sedation: a distinct minority of patients become drowsy, and this should be asked…

…depression and generalised anxiety disorder. What governs dosing is not efficacy but the heart: a dose-dependent QT prolongation was identified, and the maximum dose…

…statin dose. The first step when the statin is maximised and the LDL target is still not reached — a fixed dose of 10 mg, no…

…Absorption is destroyed by food, making the timing of administration a genuine treatment variable and not a formality. The most clinically important adverse effect is…

…is available. The effect arrives within a minute but is also short-lived — the bolus reverses unconsciousness but does not treat the cause. What determines…

…while systemic vascular resistance and diastolic blood pressure fall, so the drug raises rate but not pressure. Used where rate itself is the problem: bradycardia…

…Sweden maintains a favourable resistance situation. The spectrum covers group A streptococci and pneumococci but not Haemophilus influenzae or staphylococci. Dosing differs substantially between indications…

…in cerebral oedema and cord compression where sodium retention is undesirable. The effect is not immediate — it requires hours and never replaces adrenaline in anaphylaxis.

…V2 receptor means it lacks the vasoconstrictive effect of vasopressin. The danger is not the drug itself but the fluid the patient drinks with it.
