Amixide H Tab

Uses of Amixide H Tab

Amitriptyline is a tricyclic antidepressant. It affects chemicals in the brain that may become unbalanced. Amitriptyline is used to treat symptoms of depression. Amitriptyline may also be used for purposes not listed in this medication guide. Chlordiazepoxide is an antianxiety medication used to relieve nervousness and tension. This combination medication works faster and has less side effects than either medication alone.

Side Effects of Amixide H Tab

Postural hypotension, tachycardia, conduction disturbances. Dry mouth, wt gain, sour or metallic taste, stomatitis, constipation; blurring of vision, urinary retention, fatigue, dizziness, weakness, tremors, headache, confusion and delirium in elderly, sexual disturbances; peripheral neuropathy; urticaria, angioedema, sweating. Potentially Fatal: Cardiac arrhythmias.

Drug Interactions

Reduced effect of antihypertensives. Potentiates hypertensive effects of sympathomimetics. Concurrent use with altretamine may cause orthostatic hypotension. May increase adverse CV effects when used with amphetamines. May increase serum levels of carbamazepine. Increased risk of cardiac arrhythmias when used with β-agonists. Absorption may be reduced when used with cholestyramine, colestipol or sucralfate. Additive sedative effects when used with CNS depressants. Concurrent use with CYP2D6 inhibtors (e.g. chlorpromazine, delavirdine, fluoxetine, miconazole, paroxetine) may increase serum levels of amitriptyline. May increase antidiabetic effect of tolazamide, chlorpropamide or insulin. May reduce absorption of levodopa. Increased risk of neurotoxicity when used with lithium. Increased risk of seizures when used with tramadol. May increase anticoagulant effect of warfarin. May cause QT prolongation and fatal arrhythmias when used with drugs that prolong QT interval. Potentially Fatal: Increased risk of QT prolongation and arrhythmias when used with cisapride. Serious adverse effects e.g. hyperpyrexia, hypertension, tachycardia, confusion, seizures and deaths may occur when used with MAO inhibitors.

Contraindications

Hypersensitivity, use of MAO inhibitors within the last 14 days; acute recovery phase post-MI. Concurrent usage with cisapride.

Mechanism of Action

Amitriptyline is a TCA that exerts its action by blocking neuronal re-uptake of noradrenaline and serotonin thus increasing synaptic concentration of serotonin and/or norepinephrine in the CNS. Absorption: Readily absorbed from the GI tract (oral). Distribution: Widely distributed; crosses the placenta; enters breast milk. Protein-binding: Extensive. Metabolism: Extensively 1st-pass effect; demethylated hepatically to nortriptyline (active metabolite). Excretion: Urine (as metabolites in free or conjugated form); 9-25 hr (elimination half-life).

Special Precautions

Bipolar illness, pregnancy, lactation elderly, CVS disease, renal or liver impairment, epilepsy, thyroid dysfunction, DM. Avoid abrupt withdrawal; urinary retention, prostatic hyperplasia; chronic constipation; angle-closure glaucoma; phaeochromocytoma. Monitor for signs of clinical worsening, suicidality or behavioural changes. May increase risks associated with electro-convulsive therapy. May affect ability to drive or operate machinery.
