Q: I have high blood pressure and take Zemax to control it. I accidentally dropped a tablet in a glass of water, and it didn't dissolve at all during a full day. It was still as hard as the tablets in the container. Shouldn't the pills dissolve?
A: Most medications have a coating on the tablets that keep the pill intact until it gets into your stomach. Coatings are necessary for tablets that have an unpleasant taste, and a smoother finish makes large tablets easier to swallow. The coating also ensures that the tablet stays intact until it gets to the acidic environment it needs to be released into the body to work on the condition it is treating. If a tablet does not dissolve in water, it is not necessarily a bad thing. It goes to show the stability of the coating on the tablet and you know it will not dissolve before it gets to the digestive tract. Since our water contains no acidic properties, the tablet should not dissolve easily in it. If you were to break the coating and put the tablet in water, it will surely dissolve. Lori, PharmD
Q: My doctor just started me on blood pressure medication - Zemax-10mg. On the 5th day, I felt dizzy and not quite right. So I stopped the pill. Is it normal to feel this way?
A: Zemax is a medication that is used to treat high blood pressure. It is in a class of medications called ACE inhibitors. ACE is a chemical in the body that is used in a chemical reaction that causes our blood vessels to narrow in response to various conditions. Zemax works by blocking ACE, which, in turn, causes blood vessels to relax and bring blood pressure down. The prescribing information on Zemax lists the following as common side effects of this medication: fatigue, dizziness (especially when standing from a sitting or lying down position), cough, headache, nausea, and diarrhea. Dizziness is a common side effect in the beginning of treatment due to the body adjusting to the presence of the medication. The dizziness occurs often when blood pressure goes down or too low. This side effect usually goes away during the first week of treatment, but if you continue to have dizziness you should consult with your prescriber.

In addition, Zemax is used to increase the chance that a person will live longer after a heart attack. Zemax is also used to protect kidney function in people who have diabetes.

There are many causes of male erectile dysfunction.
