Vasotec is a prescription medication used to manage high blood pressure and certain heart conditions. It belongs to the Heart & Blood Pressure therapeutic category and contains the active ingredient Enalapril, an angiotensin-converting enzyme (ACE) inhibitor. Vasotec is supplied as a pill in three strengths: 2.5 mg, 5 mg, and 10 mg. In Hong Kong, Vasotec is regulated by the Pharmacy and Poisons Board and is available only with a medical prescription. The brand is marketed by Merck Sharp & Dohme.
Enalapril belongs to the ACE-inhibitor class. It blocks the enzyme that converts angiotensin I to angiotensin II, a potent vasoconstrictor. By reducing angiotensin II levels:
Enalapril is a pro-drug that is converted in the liver to its active form, enalaprilat. The onset of blood-pressure reduction typically occurs within one hour, with the peak effect reached in 3-6 hours. The antihypertensive effect can last up to 24 hours, allowing once-daily dosing for many patients.
Vasotec is approved by the Hong Kong Pharmacy and Poisons Board for the following indications:
These uses are based on extensive clinical trials that demonstrated reductions in blood pressure, hospitalization rates, and mortality when Enalapril is administered at appropriate doses.
If any of these conditions apply, a healthcare professional should evaluate the risks before prescribing Vasotec.
If you are taking other medicines, supplements, or herbal products, inform your healthcare provider before starting Vasotec.
Regular follow-up appointments enable dose adjustments and early detection of adverse effects.

Vasotec can be combined with other antihypertensives, such as diuretics or calcium-channel blockers, to achieve better blood-pressure control. However, the combination may increase the risk of low blood pressure, so dose adjustments and monitoring are essential.
A dry cough is a common side effect of ACE inhibitors. If the cough is bothersome or does not improve after a few weeks, contact your healthcare provider; they may switch you to a different class of medication, such as an angiotensin II receptor blocker (ARB).
Yes, Vasotec can be taken while traveling. Keep the medication in its original labeled container, carry a copy of the prescription, and be aware of any import restrictions for prescription drugs in the destination country.
There are no strict food bans, but a high-salt diet can diminish the drug’s effectiveness. Maintaining a moderate-salt diet and limiting potassium-rich supplements can help manage blood pressure and potassium levels.
Both Vasotec (Enalapril) and lisinopril belong to the same drug class and work by inhibiting ACE. Differences lie in dosing frequency, duration of action, and specific approval indications. Enalapril is often started at lower doses and may require twice-daily dosing for certain conditions, whereas lisinopril is commonly taken once daily.
Yes, Vasotec can lower blood pressure, leading to orthostatic dizziness, especially after the first few doses. Rising slowly from a seated or lying position and staying hydrated can reduce this effect.
ACE inhibitors, including Vasotec, are often preferred for patients with diabetes because they protect kidney function. Routine monitoring of kidney function and electrolytes is still recommended.
Severe reactions may include swelling of the face, lips, tongue, or throat (angio-edema), difficulty breathing, and rash. Seek emergency medical care immediately if these symptoms appear.
A history of kidney stones does not automatically preclude Vasotec use. However, because ACE inhibitors can affect renal function, periodic kidney monitoring is advisable.
Most patients notice a reduction in blood pressure within 1 hour of the first dose, with the full effect typically observed after 2-4 weeks of consistent therapy.
