Trinex<\/strong> je tizanidine 2 mg tablet<\/strong>, a centrally-acting alpha-2 adrenergic agonist<\/strong> muscle relaxant used for spasticity<\/strong> (muscle stiffness from upper motor neuron disease) and acute painful musculoskeletal spasm<\/strong>. Usual starting dose is 2 mg three times daily<\/strong>, titrated slowly up to a maximum of 36 mg\/day in 3–4 divided doses<\/strong>. Tizanidine has a short half-life (~2.5 hours), so frequent dosing is needed. The most common side effect is drowsiness; never combine with ciprofloxacin or fluvoxamine (10-fold increase in blood levels).<\/p>\n<\/div>\n \ud83d\udce6 Ka\u017ed\u00e1 objedn\u00e1vka je pokryta na\u0161\u00ed Z\u00e1rukou op\u011btovn\u00e9ho odesl\u00e1n\u00ed<\/strong><\/a> \u2014 pokud va\u0161e z\u00e1silka nedoraz\u00ed do 20 pracovn\u00edch dn\u016f, p\u0159epos\u00edl\u00e1me ji.<\/p>\n Na\u0161e generick\u00e9 l\u00e9ky poch\u00e1zej\u00ed od v\u00fdrobc\u016f certifikovan\u00fdch WHO-GMP a jsou expedov\u00e1ny po cel\u00e9m sv\u011bt\u011b v diskr\u00e9tn\u00edm, nen\u00e1padn\u00e9m balen\u00ed \u2013 na vn\u011bj\u0161\u00ed stran\u011b bal\u00edku nen\u00ed uveden n\u00e1zev l\u00e9ku.

Unlike cyclobenzaprine (a tricyclic-derived CNS depressant) or methocarbamol and metaxalone (general polysynaptic-reflex depressants), tizanidine works through a different and more targeted mechanism: it is an alpha-2 adrenergic receptor agonist<\/strong>, closely related to the antihypertensive clonidine but with a more selective effect on spinal motor reflexes.<\/p>\n Tizanidine is one of the first-line medications for spasticity<\/strong> — the muscle stiffness that develops in multiple sclerosis, spinal cord injury, stroke, cerebral palsy, and traumatic brain injury. It is also used for acute painful musculoskeletal spasm (low back pain, neck pain, muscle strain) and as an adjunct in chronic pain management.<\/p>\n Tizanidine is a central alpha-2 adrenergic receptor agonist. It acts at the spinal cord level<\/strong>, where alpha-2 receptors on presynaptic terminals of excitatory interneurons reduce the release of excitatory amino acids (glutamate, aspartate) onto motor neurons. This lowers the reflex excitability of spinal motor neurons, reducing muscle tone and spasticity without significantly affecting muscle strength or the nerve-muscle junction itself.<\/p>\n Unlike baclofen (GABA-B agonist, also used for spasticity), tizanidine does not cause the same degree of muscle weakness — which is why patients often prefer it when they still need to use the affected limb.<\/p>\n Take tizanidine consistently<\/strong>: either always with food, or always without food — not both. Food changes peak plasma concentration by up to 30%, and switching between fed and fasted states mid-course will cause unpredictable effects. Most patients find it more tolerable with food.<\/p>\n Critical drug interactions.<\/strong> Tizanidine is metabolised almost exclusively by the liver enzyme CYP1A2. Drugs that block CYP1A2 can raise tizanidine blood levels 10-fold or more — causing severe hypotension, extreme drowsiness, or loss of consciousness. Never combine tizanidine with:<\/strong> ciprofloxacin, fluvoxamine (SSRI). Use extreme caution with: norfloxacin, mexiletine, zileuton, oral contraceptives, cimetidine, propafenone, amiodarone, and ticlopidine. Always tell any new prescriber that you are on tizanidine.<\/p>\n<\/div>\n Never stop tizanidine abruptly after prolonged use.<\/strong> Withdrawal can cause rebound hypertension, tachycardia, and acute increase in spasticity. Any course longer than 2–3 weeks must be tapered down over 1–2 weeks under medical supervision.<\/p>\nPro\u010d objedn\u00e1vat z MedsBase<\/h3>\n
