How many Preato 75mg tablets to take per day?

The dosage is selected individually for a given disease, so in your case it should be determined by your doctor. If, for some reason, you do not have a dosage schedule, it is worth contacting the pharmacy where the prescription was filled. Your pharmacist will give you the information on your prescription. Otherwise, it will help to contact the doctor who prescribed the drug.

As a pharmacist, I can only give you general information:

The standard dosage of Preato is between 150 mg and 600 mg per day, given in two or three divided doses. Depending on the individual patient's response and tolerability of treatment, the dose may be gradually increased at weekly intervals. Increase your dose of Preato as your doctor has told you.

If you do not have the opportunity to consult your doctor, you can use the teleconsultation here:
