Product introduction
UDP-AT is a prescription tablet that combines amlodipine and atenolol, two medicines that act on the heart and blood vessels in different ways. It is prescribed for people with high blood pressure or angina who need both actions together. Having two medicines in one tablet can also make a daily routine simpler.
Storage: Store below 30°C in a cool, dry place, away from direct sunlight and out of reach of children.
Uses of UDP-AT Tablet
- Hypertension (high blood pressure).
- Angina (heart-related chest pain).
Benefits of UDP-AT Tablet
The combination helps bring blood pressure down and reduces episodes of chest pain caused by angina. Using two complementary mechanisms often controls blood pressure better than a single medicine, and a single tablet means fewer pills to remember.
Side effects of UDP-AT Tablet
Most side effects do not require medical attention and go away as your body adjusts. Consult your doctor if they persist.
- Ankle swelling.
- Headache.
- Sleepiness.
- Slow heart rate.
- Dizziness.
- Tiredness.
How to use UDP-AT Tablet
Take the tablet as advised by your doctor, usually once a day at about the same time, swallowed with water. Do not stop it suddenly, as stopping a beta blocker abruptly can worsen chest pain or raise blood pressure and heart rate. Keep going even when you feel well, unless your doctor says otherwise.
How UDP-AT Tablet works
Amlodipine is a calcium channel blocker that relaxes the blood vessels so blood passes through them more easily. Atenolol is a beta blocker that acts on the heart, slowing the heart rate and easing its workload. Together they lower blood pressure and reduce the heart's oxygen demand.
Substitutes for UDP-AT Tablet
These medicines have the same composition (Amlodipine (5mg) + Atenolol (50mg)) and can generally be used as alternatives. Always confirm with your doctor or our pharmacist before switching.
