Nimodipine 30 mg<\/strong>: its highly lipophilic structure lets it cross the blood-brain barrier and concentrate in cerebral vessels far more than in peripheral ones. Regulators therefore approved it for one specific neurological purpose rather than as a general antihypertensive.<\/p>\nAfter an aneurysm ruptures and causes a subarachnoid haemorrhage, the patient enters a dangerous window that usually runs from day four to day fourteen. During this period cerebral arteries constrict, blood flow to otherwise healthy tissue falls, and delayed disability may follow. Nimodipine addresses precisely this risk: it reduces the probability of delayed ischaemic neurological deficit and improves functional outcomes.<\/p>\n
\nWhat Is Nimodipine 30 mg?<\/h2>\n
Nimodipine 30 mg is a film-coated tablet containing 30 milligrams of nimodipine, a dihydropyridine calcium channel blocker. It is marketed internationally under names such as Nimotop and supplied here as Nimonidip 30 in a 100-tablet pack.<\/p>\n
Its approved indication is the prevention of ischaemic neurological deficits following aneurysmal subarachnoid haemorrhage<\/strong>. It is not licensed as a general memory enhancer or a daily brain tonic. Any use outside that indication remains an individual clinical decision made by a treating physician, never something to start after reading a product page.<\/p>\nThe tablets contain Tartrazine, the dye responsible for their yellow colour. This matters for the small group of people with known sensitivity to this colourant or to aspirin, who may experience allergic-type reactions.<\/p>\n
\nHow Does Nimodipine Work?<\/h2>\n
Smooth muscle in an arterial wall contracts only when calcium ions enter the cell through voltage-gated L-type calcium channels. Nimodipine binds these channels and blocks that influx, so the muscle cell loses its capacity for intense contraction and the vessel wall relaxes.<\/p>\n
Three practical consequences follow:<\/p>\n
\n- Relaxation of cerebral arteries<\/strong> and reduced severity of vasospasm after a bleed.<\/li>\n
- Improved perfusion<\/strong> in the vulnerable tissue surrounding the haemorrhage.<\/li>\n
- Possible neuroprotection<\/strong> by limiting calcium overload inside neurons during hypoxia, one of the pathways that leads to cell death.<\/li>\n<\/ul>\n
Nimodipine is absorbed quickly from the gut but undergoes extensive first-pass metabolism in the liver through the CYP3A4 enzyme. Any drug or food that inhibits or induces that enzyme therefore changes blood levels significantly, which is the reason the interaction section below deserves close attention.<\/p>\n
