Ralozine 500 SR 10pcs

Indications

The drug ranolazine is used to treat persistent angina. Beta-blockers, nitrates, calcium channel blockers, antiplatelet treatment, lipid-lowering therapy, ACE inhibitors, and angiotensin receptor blockers may all be used with ranolazine. On maximum dosages of amlodipine, it has been proven to reduce angina episodes in individuals with coronary artery disease. Because ranolazine prolongs the QT interval, it should only be used in individuals who have not had a satisfactory response to other antianginal medications. In women, the effect on angina rate and exercise tolerance appeared to be less than in men.

Pharmacology

Ranolazine possesses anti-ischemic and anti-langinal actions that are independent of heart rate or blood pressure decreases. Ranolazine's specific method of action is unclear. At therapeutic doses, ranolazine can block the cardiac late sodium current (INa). The link between this inhibition and angina symptoms, however, is unknown.

On the surface electrocardiogram, ranolazine prolongs the QT interval via inhibiting IKr, which prolongs the ventricular action potential.

Dosage & Administration

Initiate Ranolazine dosing at 500 mg twice daily and increase to 1000 mg twice daily, if needed, based on clinical symptoms. Take Ranolazine with or without meals. Swallow Ranolazine tablets whole; do not crush, break or chew. The maximum recommended daily dose of Ranolazine is 1000 mg twice daily. If a dose of Ranolazine is missed, take the prescribed dose at the next scheduled time; do not double the next dose.

Interaction

Strong CYP 3A inhibitors: Do not use Ranolazine if you are using a strong CYP 3A inhibitor. Limit the maximum dose of ranolazine to 500 mg twice day when using mild CYP 3A inhibitors (e.g., diltiazem, verapamil, erythromycin).

Inducers of CYP 3A: Do not use Ranolazine with inducers.

P-gp Inhibitors (e.g., Cyclosporin): Ranolazine dosage may need to be reduced based on clinical dose.

P-gp-transported or CYP2D6-metabolized medicines (e.g., digoxin, TCA) may require lower dosages when combined with ranolazine.

Contraindications

Ranolazine is not recommended for those who have a history of QT prolongation.

Hepatic impairment is a condition in which the liver is damaged.

Taking medications that lengthen the QT interval

CYP3A inhibitors, such as ketoconazole, itraconazole, clarithromycin, nefazodone, nelfinavir, ritonavir, indinavir, and saquinavir, as well as diltiazem, are used.

Side Effect

Cardiac problems include bradycardia and palpitations.

Tinnitus, vertigo, and other ear and labyrinth disorders

Abdominal discomfort, dry mouth, and vomiting are all symptoms of gastrointestinal disorders.

Peripheral edema is one of the most common side effects at the administrative site.

Dyspnea is a symptom of respiratory, thoracic, and mediastinal disorders.

Hypotension and orthostatic hypotension are two types of vascular disorders.

Pregnancy & Lactation

Pregnancy Classification C. There aren't enough research on ranolazine's effects on the growing fetus. In pregnant women, there aren't enough well-controlled research. When the possible benefit to the patient outweighs the potential danger to the fetus, ranolazine should be administered during pregnancy. Ranolazine is not known to be excreted in human milk. Because of the risk of significant side effects from ranolazine in nursing infants, a choice should be taken whether to stop breastfeeding or stop taking Ranolazine, taking into consideration the drug's value to the mother.

Precautions & Warnings

Ranolazine prolongs the QTc interval and inhibits QTc in a dose-dependent manner. In a patient group with the acute coronary syndrome, there was no evidence of an elevated risk of arrhythmia or sudden death.

Because co-administration of ranolazine with digoxin raises digoxin plasma concentrations by around 1.5-fold, the digoxin dose may need to be decreased as a result. When ranolazine is co-administered, the dosage of other P-gp substrates may need to be decreased as well. When taking ranolazine with P-gp inhibitors like ritonavir or cyclosporine, it's best to be cautious.

Storage Conditions

Ranolazine pills should be stored at 25°C, with excursions to 15° to 30°C allowed. Light and dampness should be avoided.
