Lanetik (Enalapril Maleate, Hydrochlorothiazide)

• Lanetik combines an ACE inhibitor and a thiazide diuretic to address conditions within the hypertension disease family.
• Hypertension: lowers systolic and diastolic blood pressure in patients with primary hypertension.
• Essential hypertension: provides additional blood‑pressure control when monotherapy is insufficient.
• Heart failure: assists in reducing afterload and fluid overload when combined therapy is indicated.
• Edema associated with hypertension: promotes diuresis to reduce fluid retention.

• Enalapril maleate inhibits angiotensin‑converting enzyme, decreasing formation of angiotensin II and resulting in vasodilation and reduced aldosterone release. Hydrochlorothiazide blocks Na⁺/Cl⁻ reabsorption in the distal convoluted tubule, increasing urinary sodium and water excretion, which lowers blood volume and further reduces arterial pressure.

Common Side Effects

• Cough: dry, persistent throat irritation.
• Dizziness or light‑headedness, especially after standing.
• Headache.
• Increased urination.
• Fatigue.
• Electrolyte changes such as mild potassium loss.

Serious or Rare Side Effects

• Angioedema: swelling of face, lips, tongue, or airway.
• Severe hypotension: marked drop in blood pressure.
• Acute renal impairment or failure.
• Hyperkalemia: elevated potassium levels.
• Pancreatitis (rare).

Before initiating therapy, clinicians should consider the following precautions:

• Monitor blood pressure regularly: ensure target levels are achieved without excessive drop.
• Assess renal function: adjust dose in patients with impaired kidney function.
• Check electrolytes: watch for sodium, potassium, and chloride abnormalities.
• Avoid use in pregnancy: ACE inhibitors are contraindicated during the second and third trimesters.
• Use caution with NSAIDs: may reduce antihypertensive efficacy and affect renal function.
• Adjust in diabetes: monitor glucose and renal parameters closely.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture.

Lanetik may interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Potassium‑sparing diuretics or supplements: risk of hyperkalemia.
• Lithium: increased lithium levels and toxicity.
• Aliskiren (in diabetics): heightened risk of renal impairment and hypotension.
• NSAIDs: may blunt antihypertensive effect and impair renal function.

Moderate Interactions (Monitor Closely)

• Other antihypertensives (beta‑blockers, calcium channel blockers): additive blood‑pressure lowering.
• Antacids containing aluminum or magnesium: may reduce absorption of enalapril.
• Rifampin or other enzyme inducers: may decrease plasma concentrations of enalapril.
