5 Storage of Angiodrox 300 mg capsules
Angiodrox 300 mg capsules, whose active ingredient is diltiazem, belong to a group of medicines called calcium antagonists. Angiodrox is used for the treatment and prevention of angina pectoris, as it widens (dilates) the heart's arteries, increasing blood flow. Angiodrox also acts by widening other blood vessels in the body, so it is also used in the treatment of high blood pressure (hypertension).
Do not take Angiodrox 300 mg capsules:
Warnings and precautions
Consult your doctor or pharmacist before starting to take Angiodrox 300 mg capsules.
If you have a history of heart failure, new difficulty breathing, slow heartbeats, or low blood pressure. There have been reports of kidney damage in patients with these conditions, it is possible that your doctor may need to monitor your kidney function.
Since the therapeutic effect has not been compared between different diltiazem specialties with immediate or modified release (retard), according to whether they are rapidly absorbed or not in the digestive tract, it is not recommended to substitute one for another unless expressly recommended by the prescribing doctor.
Detailed observation is necessary in patients with heart problems.
If you are diabetic, you may need an adjustment in the treatment you are already receiving.
If you have liver or kidney disease or are an elderly patient, your doctor will carefully monitor you for any changes, especially in your heart rate (beats per minute).
Calcium channel blockers, such as Angiodrox, may be associated with mood changes, including depression.
Angiodrox has an inhibitory effect on intestinal movements. Therefore, it should be used with caution in patients at risk of developing intestinal obstruction. The residues of the tablets of the slow-release formulations may pass into the patient's feces; however, this fact has no clinical relevance.
If you have acute porphyria, it is not safe for you to take Angiodrox.
The use of Angiodrox in chronic stable angina should be limited to patients who do not tolerate adequate doses or are refractory to treatment with beta-blockers and/or oral nitrates.
If you have any cardiac arrhythmia (sinus node disease, atrioventricular block) or if you are receiving treatment with other medicines used to treat heart diseases (beta blockers, digitalis), since the use of diltiazem in these situations may lead to an excessively slow pulse and heart rhythm (bradycardia).
If you have hypotension (low blood pressure): treatment with diltiazem may lead to an excessive drop in blood pressure. Your doctor will inform you about how to avoid the symptoms resulting from hypotension and what measures to take if these symptoms occur.
In rare cases, Angiodrox may cause liver damage, which is reversible when treatment is discontinued.
If you are going to undergo surgery that requires general anesthesia, you should inform your doctor and anesthesiologist about the treatment with Angiodrox.
If you have liver or kidney disease, it should be used with caution.
The use of diltiazem has been associated with skin reactions. Your doctor will assess these symptoms and indicate the measures to be taken.
Other medicines and Angiodrox 300 mg capsules
Tell your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription.
Contraindicated use with other medicines:
The combination of diltiazem and dantrolene in infusion (muscle relaxant) is potentially hazardous.
Use with other medicines that requires caution:
Lithium (used to treat certain mental illnesses): risk of increased lithium-induced neurotoxicity.
Nitrate derivatives (to treat hypertension): increased hypotensive effects (excessive drop in blood pressure) and fainting. In all patients treated with Angiodrox, the prescription of nitrate derivatives should only be done in gradually increasing doses.
Theophylline (used to treat asthma): increased theophylline levels in the blood.
Alpha-antagonists (to treat hypertension): may produce or worsen hypotension. The combination of diltiazem with an alpha-antagonist should only be considered with strict blood pressure control.
Amiodarone (used to decrease heart rate), digoxin (used to treat heart diseases): increased risk of bradycardia (decreased heartbeats). Caution should be exercised when these are combined with diltiazem, particularly in elderly subjects and when high doses are used.
Beta-blockers (to treat hypertension): possibility of alterations in the heart.
Other antiarrhythmic agents (used to prevent or suppress cardiac rhythm disturbances): since diltiazem has antiarrhythmic properties, it is not recommended to prescribe it together with other antiarrhythmic agents.
Carbamazepine (to treat epilepsy): increased carbamazepine levels in the blood:
Rifampicin (antibiotic): risk of decreased diltiazem levels in the blood after starting treatment with rifampicin.
Agents used to decrease stomach acid production (cimetidine, ranitidine): increased diltiazem levels in the blood.
Ciclosporin (used to suppress the immune system): increased ciclosporin levels in the blood.
In particular, do not take this medicine and inform your doctor if you are taking:
Medicines that contain lomitapida, used for the treatment of high cholesterol levels.
Diltiazem may increase the concentration of lomitapida, which may lead to an increased probability and severity of selected side effects on the liver.
The combined use of Angiodrox with other drugs should be done under medical control and adjusting the doses progressively.
General information to be taken into account
Due to the possibility of additive effects, it is necessary to exercise caution and carefully assess patients who receive Angiodrox simultaneously with other agents known to affect the heart.
Angiodrox is metabolized in the liver by the CYP3A4 isoenzyme, but it also inhibits it. Other drugs have similar or opposite metabolism, and cases of increased blood levels of one or another drug may occur, depending on whether they inhibit or not this liver enzyme.
Benzodiazepines (midazolam, triazolam used to treat anxiety): diltiazem increases midazolam and triazolam levels in the blood.
Corticosteroids (methylprednisolone, used to treat inflammatory problems): diltiazem may increase methylprednisolone levels in the blood and may require a dose adjustment of methylprednisolone.
Statins (medicines to decrease cholesterol levels in the blood): diltiazem increases the levels of some statins in the blood. There is a risk of myopathy (muscle disorder) and rhabdomyolysis (muscle necrosis with complications such as kidney failure) with the simultaneous use of diltiazem and some statins.
