About Onato Tablet 10mg
Onato is a calcium channel blocker containing amlodipine, used to treat high blood pressure and angina.
Onato Tablet Uses
- Treatment and control of high blood pressure (hypertension) in adults.
- Relief of angina (chest pain) caused by reduced blood flow to the heart.
- Prevention of coronary artery disease and related cardiovascular complications.
- Reduction of risk for heart attack and stroke in hypertensive patients.
Onato Tablet Benefits
- Effectively lowers blood pressure and reduces workload on the heart.
- Provides rapid relief from angina symptoms within 2-3 hours.
- Does not slow heart rate, making it suitable for patients with existing cardiac conditions.
- Can be taken with or without food, offering dosing flexibility.
- Generally well-tolerated with fewer side effects than other antihypertensive classes.
What Experts Say
Amlodipine is a dihydropyridine calcium channel blocker that selectively inhibits L-type calcium channels in vascular smooth muscle cells. By blocking calcium influx, amlodipine prevents smooth muscle contraction and causes vasodilation, reducing peripheral vascular resistance and lowering blood pressure without significantly affecting heart contractility.
The drug exhibits high selectivity for vascular tissues with minimal cardiac effects, making it particularly valuable for patients with certain cardiac conditions. Amlodipine has a longer half-life compared to other calcium channel blockers, allowing for once-daily dosing and maintaining stable blood pressure control throughout the day.
Peak blood pressure reduction occurs 6 to 12 hours after administration. Full therapeutic benefit is typically achieved within 1-2 weeks of regular use. Amlodipine undergoes hepatic metabolism and has a terminal elimination half-life of 30-50 hours, ensuring sustained action with a single daily dose.

Drug Interactions
Amlodipine may interact with several medications affecting blood pressure and metabolism:
- CYP3A4 inhibitors: Ketoconazole and other inhibitors may increase amlodipine levels.
- Beta-blockers: Combined use may increase hypotensive effects; monitor blood pressure.
- Grapefruit juice: May increase amlodipine levels; avoid concurrent consumption.
- Simvastatin: Amlodipine may increase simvastatin levels, increasing myopathy risk.
- NSAIDs: May reduce antihypertensive effectiveness and increase renal dysfunction.
Risks and warnings
- Pregnancy: Use only if potential benefit justifies fetal risk; consult physician.
- Breastfeeding: Amlodipine passes into breast milk; consult before use.
- Hepatic impairment: Dose adjustment required in patients with liver disease.
- Heart failure: Use with caution in patients with severely reduced heart function.
- Hypotension: May cause excessive blood pressure reduction; monitor regularly.
- Grapefruit interaction: Avoid grapefruit juice as it increases amlodipine levels.
- Angina rebound: Do not stop taking suddenly to avoid angina worsening.
