Olmesta40 mg

Olmesta 40 mg is indicated for the treatment of hypertension. It may be used alone or in combination with other antihypertensive agents.

Angiotensin-ll receptor blocker

Olmesartan medoxomil is a potent, orally active, selective angiotensin II receptor (type AT1) antagonist. It is expected to block all actions of angiotensin II mediated by the AT1 receptor, regardless of the source or route of synthesis of angiotensin II. The selective antagonism of the angiotensin II (AT1) receptors results in increases in plasma renin levels and angiotensin I and II concentrations, and some decrease in plasma aldosterone concentrations. Angiotensin II is the primary vasoactive hormone of the renin-angiotensin- aldosterone system (RAAS) and plays a significant role in the pathophysiology of hypertension via the type 1 (AT1) receptor.

Adult: Dosage must be individualized. The usual initial dose is 10 mg once daily. In patients whose blood pressure is not adequately controlled at this dose, the dose may be increased to 20 mg once daily as the optimal dose. For patients requiring further reduction in blood pressure after 2 weeks of therapy, the dose of Olmesartan may be increased to 40 mg. Doses above 40 mg do not appear to have greater effect.Pediatric Use: Safety and effectiveness in pediatric patients have not been established.Geriatric Use: Of the total number of hypertensive patients receiving Olmesta 40 mg in clinical studies, more than 20% were 65 years of age and over, while more than 5% were 75 years of age and older. No overall differences in effectiveness or safety were observed between elderly patients and younger patients.

Dosage must be individualized. The usual recommended starting dose of Olmesartan is 20 mg once daily when used as monotherapy in patients who are not volume-contracted. For patients requiring further reduction in blood pressure after 2 weeks of therapy, the dose of Olmesartan may be increased to 40 mg. Doses above 40 mg do not appear to have a greater effect. Twice-daily dosing offers no advantage over the same total dose given once daily. No initial dosage adjustment is recommended for elderly patients, for patients with moderate to marked renal impairment (creatinine clearance <40 ml/min) or with moderate to marked hepatic dysfunction. For patients with possible depletion of intravascular volume (e.g. patients treated with diuretics, particularly those with impaired renal function), Olmesartan should be initiated under close medical supervision and consideration should be given to use of a lower starting dose. Olmesartan may be administered with or without food.

With medicine: No significant drug interactions were reported in which Olmesartan was co-administered.With food & others: Food does not affect the bioavailability of Olmesartan.

Olmesartan is contraindicated in patients who are hypersensitive to any component of this product.

Common: The most common side effects include Back pain, bronchitis, creatine phosphokinase increased, diarrhea, headache, hematuria, hyperglycemia, hypertriglyceridemia, influenza-like symptoms, pharyngitis, rhinitis, and sinusitis.Rare: Chest pain, peripheral edema, arthritis.

Pregnancy Categories C (first trimester) and D (second and third trimesters).Nursing Mothers: It is not known whether Olmesartan is excreted in human milk, but Olmesartan is secreted at low concentration in the milk of lactating rats. Because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals treated with Olmesta 40 mg. In patients whose renal function may depend upon the activity of the renin-angiotensin-aldosterone system (e.g. patients with severe congestive heart failure), treatment with angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists has been associated with oliguria and/or progressive azotemia and (rarely) with acute renal failure and/or death. Similar results may be anticipated in patients treated with Olmesta 40 mg.

Symptoms: There is no experience of overdose with Olmesartan. The most likely effects of Olmesta 40 mg overdosage are hypotension and tachycardia; bradycardia could be encountered if parasympathetic (vagal) stimulation occurred.Treatment: If intake is recent, gastric lavage or induction of emesis may be considered. Clinically significant hypotension due to an overdose of Olmesartan requires the active support of the cardiovascular system, including close monitoring of heart and lung function, the elevation of the extremities, and attention to circulating fluid volume and urine output.

Store in cool & dry place below 30ºC, protect from light & moisture. Keep out of the reach of children.

Hepatic Impairment: Dose should not exceed 20 mg daily in moderate impairment.Renal Impairment: Max. 20 mg daily if eGFR 20–60 mL/minute/1.73 m2. Avoid if eGFR less than 20 mL/minute/1.73 m2.

Angiotensin-ll receptor blocker

Angiotensin-II formed from angiotensin-I in a reaction catalyzed by angiotensin-converting enzyme (ACE), is a potent vasoconstrictor, the primary vasoactive hormone of the renin-angiotensin system and an important component in the pathophysiology of hypertension. It also stimulates aldosterone secretion by the adrenal cortex. Olmesartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin-II by selectively blocking the binding of angiotensin-II to the AT 1 receptor found in many tissues (e.g. vascular smooth muscle, adrenal gland). In-vitro-binding studies indicate that Olmesartan is a reversible & competitive inhibitor of AT 1 receptor. Olmesartan does not inhibit ACE (kinase-I, the enzyme that converts angiotensin-I to angiotensin-II and degrades bradykinin).

Pregnancy: When pregnancy is detected, discontinue this product as soon as possible. When used in pregnancy during the second and third trimesters, drugs that act directly on the renin-angiotensin system can cause injury and even death to the developing fetus.Nursing Mothers: It is not known whether Olmesartan is excreted in human milk, but Olmesartan is secreted at low concentration in the milk of lactating rats. Because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Paediatric use: Safety and effectiveness in paediatric patients have not been established.
