Generally there is no adverse reaction of irritating dry cough or cough when taking Timosartan.
Timosartan belongs to the angiotensin II receptor antagonist, clinically used in the treatment of hypertension. The main adverse reactions are dizziness, headache, back pain, nausea, decreased appetite, diarrhea, upper respiratory tract infections, etc. Most of these adverse reactions will resolve on their own within 3 days.
A very small number of patients may develop angioedema, pruritus, rash, and urticaria. Adverse reactions of irritating dry cough or cough do not occur.
The adverse reaction of irritating dry cough is common with another class of antihypertensive drugs angiotensin-converting enzyme inhibitors, such as captopril and enalapril. The reason for this is that because angiotensin-converting enzyme inhibitors cause bradykinin and substance P to accumulate in the lungs, the respiratory system is irritated by the overproduction of prostaglandins. In addition to this, bradykinin enhances the sensitivity of the sensory nerves in the respiratory tract causing coughing.
If you feel unwell while taking timosartan, seek medical attention and follow your doctor’s instructions.
