About This Medication

What is GD-Amlodipine/Atorvastatinused For

GD-amlodipine/atorvastatin is a product that contains two active ingredients: amlodipine and atorvastatin and is to be used when your doctor deems it appropriate to use both medications.

Your doctor has prescribed GD-amlodipine/atorvastatin to you to control your hypertension (high blood pressure) and/or to prevent angina attacks (chest pains) and to help lower your cholesterol or other fats in the blood (such as triglycerides). Even if you do not have high cholesterol, your doctor may still prescribe GD - amlodipine/atorvastatin if you have high blood pressure and other risk factors in order to prevent your risk of cardiovascular disease such as heart attacks.

GD-amlodipine/atorvastatin is just part of the treatment your doctor will plan with you to help keep you healthy. Depending on the condition of your health and your lifestyle, your doctor may recommend:

  • a change in your diet to control your weight, reduce your cholesterol, reduce intake of saturated fats and increase fiber
  • exercise that is right for you
  • quitting smoking or avoiding smoky places
  • giving up alcohol or drinking less

GD-amlodipine/atorvastatin is not recommended in children.

What GD-Amlodipine/Atorvastatin Does

The amlodipine portion of GD-amlodipine/atorvastatin belongs to a class of medications called calcium channel blockers. Calcium channel blockers, like amlodipine, block the transfer of calcium into the cells of the heart and blood vessels. This helps the blood vessels to relax, thereby lowering blood pressure and resulting in less work for the heart.

The atorvastatin portion of GD-amlodipine/atorvastatin belongs to the class of medicines known as “statins”, more specifically called HMG-CoA reductase inhibitors. HMG-CoA reductase is an enzyme involved in regulating cholesterol levels in your body. Statins are used along with changes to exercise and diet to help control the amount of cholesterol produced by the body. High levels of cholesterol and other fats can cause heart disease by clogging the blood vessels that feed blood and oxygen to the heart.

Atorvastatin can help your body:

  • Decrease LDL (bad) cholesterol, triglyceride levels and other lipids/fats in the blood.
  • Increase HDL (good) cholesterol
  • Decrease the Total Cholesterol HDL-Cholesterol Ratio (TC: HDL-C Ratio). The ratio represents the balance between bad and good cholesterol.

Follow your doctor’s instructions carefully.
