Description
Overview of the medicine
Azilpres Plus 40 mg Tablet is a combination medicine used to treat high blood pressure (hypertension). It works by relaxing blood vessels, allowing blood to flow more easily, and by increasing the excretion of salt and water, which further lowers blood pressure.
Uses & Indications
Dosage
Adults
The usual recommended dose is one Azilpres Plus 40 mg/12.5 mg tablet once daily. The dose may be adjusted by the physician based on individual patient response.
Elderly
No specific dose adjustment is generally required for elderly patients, but caution is advised, especially in those with renal impairment.
Renal_impairment
Initial dose adjustment may be required for patients with moderate to severe renal impairment. Not recommended in severe renal impairment (creatinine clearance <30 mL/min) or anuria.
How to Take
Take the tablet orally once daily with or without food. It should be swallowed whole with a glass of water. Try to take it at the same time each day to maintain consistent blood levels.
Mechanism of Action
Azilsartan Medoxomil is a prodrug that is converted to Azilsartan, an angiotensin II receptor blocker (ARB). It selectively blocks the binding of angiotensin II to the AT1 receptor in many tissues, including vascular smooth muscle and the adrenal gland. This inhibits the vasoconstrictor and aldosterone-secreting effects of angiotensin II, leading to vasodilation and reduced blood pressure. Chlorthalidone is a thiazide-like diuretic that acts on the distal convoluted tubule of the kidney to inhibit sodium and chloride reabsorption, leading to increased excretion of sodium, chloride, and water, thereby reducing plasma volume and blood pressure.
Pharmacokinetics
Onset
Blood pressure reduction typically occurs within 1-2 hours for Azilsartan and within 2-3 hours for Chlorthalidone. Maximum effect may take several weeks.
Excretion
Azilsartan is primarily excreted via feces (55%) and urine (42%). Chlorthalidone is primarily excreted unchanged in the urine (approximately 77% within 120 hours).
Half life
Azilsartan has an elimination half-life of approximately 11 hours. Chlorthalidone has a prolonged elimination half-life of approximately 40-60 hours.
Absorption
Azilsartan medoxomil is rapidly absorbed and converted to azilsartan during absorption. Bioavailability is approximately 60%. Chlorthalidone is absorbed relatively slowly from the gastrointestinal tract, with bioavailability of approximately 64%.
Metabolism
Azilsartan is metabolized to inactive metabolites, primarily via O-dealkylation and non-CYP dependent carboxylation. Chlorthalidone is minimally metabolized.
Side Effects
Contraindications
- Hypersensitivity to Azilsartan, Chlorthalidone, or any component of the formulation
- Anuria (absence of urine production)
- Severe renal impairment (creatinine clearance <30 mL/min)
- Pregnancy (second and third trimesters)
- Concomitant use with Aliskiren in patients with diabetes mellitus or renal impairment (GFR <60 mL/min/1.73 m²)
- Severe hepatic impairment
Drug Interactions
Digoxin
Chlorthalidone-induced hypokalemia may enhance digoxin toxicity.
Lithium
Diuretics reduce renal clearance of lithium, leading to increased lithium levels and toxicity. Monitor lithium levels.
Other antihypertensive agents
May have additive hypotensive effects.
NSAIDs (Nonsteroidal Anti-inflammatory Drugs)
May reduce the antihypertensive effect and increase the risk of renal function deterioration.
Potassium-sparing diuretics, potassium supplements, or salt substitutes containing potassium
May lead to hyperkalemia (high potassium levels).
Storage
Store in a cool, dry place, away from direct light and moisture. Keep out of reach of children. Store below 30°C.
Overdose
Symptoms of overdose may include profound hypotension, dizziness, and electrolyte disturbances (e.g., hypokalemia, hyponatremia). Treatment is supportive and symptomatic. If ingestion is recent, gastric lavage may be considered. Closely monitor vital signs and serum electrolytes.
Pregnancy & Lactation
Contraindicated during the second and third trimesters of pregnancy due to risk of fetal harm. Not recommended during breastfeeding as it is unknown if Azilsartan is excreted in human milk, and chlorthalidone is excreted in milk.
