Angirid MR
Angirid MR Uses, Dosage, Side Effects, Food Interaction and all others data.
Angirid MR is an anti-ischemic (anti-anginal) metabolic agent, which improves myocardial glucose utilization through inhibition of long-chain 3-ketoacyl CoA thiolase activity, which results in a reduction in fatty acid oxidation and a stimulation of glucose oxidation. High fatty acid oxidation rates are detrimental during ischemia due to an inhibition of glucose oxidation leading to uncoupling of glycolysis and an increase in proton production, which has the potential to accelerate sodium and calcium overload in the heart. This leads to an exacerbation of ischemic injury and decreased cardiac efficiency during reperfusion.
Angirid MR is indicated for the symptomatic treatment of stable angina pectoris in patients inadequately controlled or intolerant to first line therapies. Patients should be counselled regarding the risk of use with reduced renal or hepatic function, worsening of extrapyramidal symptoms or other movement disorders, and risk of falls.

How Angirid MR works
During myocardial ischemia, anaerobic metabolism takes over, increasing levels of lactic acid. The decreased intracellular pH and increased concentration of protons activates sodium-hydrogen and sodium-calcium antiport systems, raising intracellular calcium concentrations, finally leading to decreased contractility.
This injury to the myocardium raises concentrations of catecholamines, which activate hormone sensitive lipase, and increasing fatty acid concentrations in plasma. When the myocardium is repurfused, fatty acid oxidation becomes the dominant form of ATP production, maintaining an acidic pH, and further exacerbating the injury.
The mechanism of action of trimetazidine is not fully understood. Angirid MR may inhibit mitochondrial 3-ketoacyl coenzyme A thiolase, decreasing long chain fatty acid β-oxidation but not glycolysis in the myocardium. The decreased long chain fatty acid β-oxidation is compensated for by increased use of glucose, preventing a lowered myocardial pH, and further decreases in contractility. However, another study suggests that 3-ketoacyl coenzyme A thiolase may not be trimetazidine's target, and that this mechanism may be incorrect.
Dosage
Angirid MR dosage
One 20 mg tablet thrice daily after meals. No dosage adjustments are required in patients with impaired renal and hepatic function.
One 35 mg modified release tablet twice daily at mealtimes in the morning and evening.
Side Effects
Angirid MR is safe and well tolerated. The most commonly encountered side effects are gastric discomfort, nausea, headache and vertigo. However, the side effects are mild and non-specific.
Toxicity
Data regarding overdoses of trimetazidine are not readily available. Treat overdoses with symptomatic and supportive therapy.
The oral LD50 in rats is 1700 mg/kg, and in mice is 1550 mg/kg. The subcutaneous LD50 in rats is 1500 mg/kg, and in mice is 410 mg/kg.
Interaction
No drug interactions have so far been reported. In particular, no interactions of Angirid MR with beta-blockers, calcium antagonists, nitrates, heparin, hypolipidemic agents or digitalis have been reported.
Food Interaction
- Take with food. Take during a meal.
- Take with plain water. Take with a glass of water.
Volume of Distribution
The volume of distribution of trimetazidine is 4.8 L/kg.
Elimination Route
In elderly patients, a 35 mg oral modified release tablet reaches a mean Cmax of 115 µg/L, with a Tmax of 2.0-5.0 hours, and a mean AUC0-12 of 1104 h*µg/L. In young, healthy patients, the same dose reaches a mean Cmax of 91.2 µg/L, with a Tmax of 2.0-6.0 hours, and an AUC0-12h 720 h*µg/L.
Half Life
In young, healthy subjects, the half life of trimetazidine is 7.81 hours. In patients over 65, the half life increases to 11.7 hours.
Clearance
Angirid MR clearance is strongly correlated with creatinine clearance. In eldery patients with a creatinine clearance of 72 ± 8 mL/min, trimetazidine clearance was 15.69 L/h. In young, healthy patients with a creatinine clearance of 134 ± 18 mL/min, trimetazidine clearance was 25.2 L/h.
Elimination Route
Angirid MR is 79-84% eliminated in the urine, with 60% as the unchanged parent compound. In a study of 4 healthy subjects, individual metabolites made up 0.01-1.4% of the dose recovered in urine. In the urine, 2-desmethyltrimetazidine made up 0-1.4% of the recovered dose, 3- and 4-desmethyltrimetazidine made up 0.039-0.071% each, N-methyltrimetazidine made up 0.015-0.11%, trimetazidine ketopiperazine made up 0.011-0.4%, N-formyltrimetazidine made up 0.035-0.42%, N-acetyltrimetazidine made up 0.016-0.19%, desmethyl trimetazidine O-sulphate made up 0.01-0.65%, and an unknown metabolite made up0.026-0.67%.
Pregnancy & Breastfeeding use
Pregnancy: Studies in animals have not demonstrated a teratogenic effect. However, in the absence of clinical data and for safety reasons, prescription should be avoided during pregnancy.
