Irbesartan capsules and Irbesartan tablets are both angiotensin-II receptor antagonist antihypertensive drugs made with Irbesartan as the main ingredient, suitable for the treatment of hypertension. They should be contraindicated for those who are allergic to the product, pregnant women and lactating women. Theoretically, both drugs have the same composition, and the antihypertensive effect of the two drugs is the same under the same dosage, but taking into account the variability of individual users, the final antihypertensive effect may not be the same, so it is not possible to say which drug is better.
