Benadryl Hydrochloride Tablets have some antihypertensive effect, but the specific efficacy varies from person to person, and it is not possible to state the specific antihypertensive effect as a whole. It should be used in accordance with medical advice.
Benadryl Hydrochloride Tablets is an angiotensin-converting enzyme inhibitor with long-acting antihypertensive effect, suitable for the treatment of all stages of hypertension as well as adjunctive treatment of some patients with congestive heart failure, such as patients with congestive heart failure who have poor response to digitalis and/or diuretics, and whose NYHA classification is in the range of class II to IV.
The antihypertensive effect of the drug cannot be assessed as a whole, mainly because of the individual variability of users, resulting in specific antihypertensive effects varying from person to person. Note that the drug is contraindicated in persons who are hypersensitive to the product and in persons with a history of angioneurotic edema. Common adverse reactions include flushing, headache, syncope, palpitations, upright intolerance, cough, rash, itching and so on.
Specific medication should be administered under the supervision of a specialist.
