Nebilol
📌 COMPOSITION
Each tablet contains: Nebivolol HCl equivalent to Nebivolol 5 mg.
📌 DESCRIPTION
Nebilol (Nebivolol) is a cardiovascular drug belonging to the beta‑receptor blockers group, and it is the most selective drug for beta 1 receptors in this class, which makes its effect more specific for the heart, so it prevents increased heart rate and controls heart pumping strength. Nebivolol has a unique effect among other drugs by potentiating nitric oxide, which causes dilation of blood vessels. These effects make Nebilol an antihypertensive drug. Nebilol can be used in patients with or at risk of erectile dysfunction because it does not significantly worsen erectile function as other beta blockers do. Nebivolol is rapidly absorbed after oral administration, predominantly bound to albumin. One week after administration, 38% of it is excreted in the urine and 48% in faeces.
📌 INDICATIONS
Treatment of essential hypertension.
📌 DOSAGE AND ADMINISTRATION
The daily dose of Nebilol should be taken at the same time daily with a sufficient amount of water and can be taken with meals.
- Adults: 5 mg (one tablet) daily.
- Patients with impaired kidney function: The recommended initial dose is 2.5 mg (1/2 tablet) daily. If required, the daily dose can be increased to 5 mg (one tablet).
- Elderly patients:
- Patients aged over 65 years: The recommended initial dose is 2.5 mg (1/2 tablet) daily. If necessary, the daily dose can be increased to 5 mg (one tablet).

📌 DRUG INTERACTIONS
The doctor should be informed if the patient is using one of the following drugs:
- Medicines for controlling blood pressure or medicines for heart problems (such as amiodarone, amlodipine, cibenzoline, clonidine, digoxin, diltiazem, disopyramide, felodipine, flecainide, guanfacine, hydroquinidine, lacidipine, lidocaine, methyldopa, mexiletine, moxonidine, nicardipine, nifedipine, nimodipine, nitrendipine, propafenone, quinidine, rilmenidine, verapamil).

- Medicines for depression, e.g., amitriptyline, paroxetine, fluoxetine.

- Medicines for asthma, blocked nose or certain eye disorders such as glaucoma (increased pressure in the eye) or dilation (widening) of the pupil.
- Baclofen (an antispasmodic drug) or amifostine (a protective medicine used during cancer treatment). All these drugs, as well as nebivolol, may influence blood pressure and/or heart function.
- Medicines for treating excessive stomach acid or ulcers (antacid drugs): the patient should take Nebilol during a meal and the antacid drug between meals.
