Description minoxidil dilminox is an orally active peripheral vasodilator. The pure compound is soluble in liquid for the extent of approximately 2 mg/ml and is readily soluble in propylene glycol or ethanol. Chemically, Minoxidil dilminox is 2. 4, Diamino, 6, Piperidino, Pyrimidine, 3, Oxide. The molecular weight is 209. 25. Composition each uncoated tablet of dilminox contains minoxidil i. P. 5 mgpharmacology minoxidil dilminox selectively relaxes the arteriolar which reduces, Smooth muscle peripheral vascular resistance and lowers systemic blood pressure. This represents accomplished without a diminution of nutritional flow to body tissues or interference with normal vasomotor reflexes. Minoxidil dilminox does not directly stimulate the heart or electrolyte reabsorption of the minoxidil s, Kidney. However dilminox administration elicits a reflex mediated increase in cardiac output, Salt and water retention as well as a rise in plasma renin activity. These effects are diminished by the simultaneous administration of diuretics and beta, Adrenergic blocking agents. Gastrointestinal absorption is rapid and amounts to at least 95% of the administered dose. Serum levels of the parent drug peak within the first hour. The plasma elimination half, Life of minoxidil dilminox is approximately 4, 4. 5 hours, But the length of time its hypotensive action may exceed 24 hours. This disparity between blood level and pharmacological effect and the substantial amount of distribution indicated extensive tissue localization of the on chronic, Drug. However treatment, Accumulation does not occur and the pharmacological effect is slowly reversible. With an effective blood pressure, Oral dose usually starts to decline within one half hour, Reaches a minimum between 2 and 3 hours and recovers at a rate of approximately 30%/day. During you will, Daily administration find a cumulative effect which reaches a steady state after 3 to 7 days. The magnitude concerning the circulatory fluid pressure response is connected to the extent of the first edition diastolic elevation above 85 mm hg and is proportional to the logarithmic purpose of the dose administered. When the desired diastolic reduction is greater than 30 two times, Mm hg daily dosing is advised to maintain the diurnal variation within 10 mm hg. Minoxidil does not bind to enter the, Plasma proteins central nervous system or accumulate in body tissues. Metabolism is predominantly by glucuronic acid conjugation. Metabolites are excreted principally in the urine and has the capability to being taken off by hemodialysis in anephric patients. Hemodialysis does not, However, Rapidly reverse the pharmacological effect of minoxidil. Indications it is indicated as adjunctive therapy in adults with severe refractory hypertension, Which has failed to respond to extensive multiple therapies. When used together with an accompanying diuretic and beta, Blocker, Minoxidil dilminox has been shown to reverse encephalopathy and retinopathy in severe hypertensives. Contraindications minoxidil dilminox is contraindicated in phaeochromocytoma and pulmonary hypertension secondary to mitral stenosis. Warnings if used alone, Minoxidil dilminox can cause a significant retention neck vein distention and, Puffiness of face, Eyes of salt, Or hands and water, Producing dependent oedema hepatojugular reflux. Chest x, Rays may show evidence of pulmonary vascular engagement.
