Hidralazina Kronos is used to treat high blood pressure (hypertension). It is also used to control high blood pressure in a mother during pregnancy (pre-eclampsia or eclampsia) or in emergency situations when blood pressure is extremely high (hypertensive crisis).
High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can increase the risk of heart attacks and strokes.
Hidralazina Kronos works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its workload.
Hidralazina Kronos is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although this use is not specifically included in product labeling, Hidralazina Kronos is used in certain patients with the following medical condition:
Congestive heart failure.

Hidralazina Kronos Dosage
Generic name: Hidralazina Kronos hydrochloride
Dosage form: Tablets
The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
Initiate therapy in gradually increasing dosages; adjust according to individual response. Start with 10 mg four times daily for the first 2-4 days, increase to 25 mg four times daily for the balance of the first week. For the second and subsequent weeks, increase dosage to 50 mg four times daily. For maintenance, adjust dosage to the lowest effective levels.
The incidence of toxic reactions, particularly the L.E. cell syndrome, is high in the group of patients receiving large doses of Hidralazina Kronos.
In a few resistant patients, up to 300 mg of Hidralazina Kronos daily may be required for a significant antihypertensive effect. In such cases, a lower dosage of Hidralazina Kronos combined with a thiazide and/or reserpine or a beta blocker may be considered. However, when combining therapy, individual titration is essential to ensure the lowest possible therapeutic dose of each drug.
