Osartil 50 Plus is a combination medication containing (Losartan Potassium 50mg + Hydrochlorothiazide 12.50mg). It is used for the treatment of essential hypertension, also known as high blood pressure. Essential hypertension can lead to severe damage to blood vessels and various organs, including the heart, kidneys, and eyes. Osartil 50 Plushelps lower blood pressure by blocking the actions of Angiotensin II, which narrows blood vessels, and by increasing urine output through its diuretic effect.
During treatment with Osartil 50 Plus, your doctor needs to monitor your blood pressure, kidney function, and electrolyte levels regularly to ensure proper management and minimize potential side effects. It is worth noting that Osartil 50 Plus is not suitable for use in children under 18 years of age or in adult patients with severe kidney or liver impairment.
Long-term use of Osartil 50 Plus may increase the risk of certain types of skin and lip cancer. Therefore, it is advisable to protect your skin from sun rays and UV exposure while using this medication. Additionally, Osartil 50 Plus is not recommended for use in breastfeeding women and pregnant women, especially after the third month of gestation, as it may pose potential harm to the unborn baby. it is always best to consult a healthcare professional or refer to the medication's package insert for specific details and recommendations regarding the use of Osartil 50 Plus.
Alcohol should not be consumed with Osartil 50 Plus tablet as it may cause orthostatic hypotension (a type of low blood pressure that occurs when you stand up after sitting down or lying).
Osartil 50 Plus is not recommended for pregnant women.
Osartil 50 Plus is not recommended for women who are breastfeeding.
Osartil 50 Plus may cause dizziness or drowsiness. If you experience any such effects after taking this medicine that may affect your ability to drive safely, it is advised to avoid driving.
Osartil 50 Plus is not recommended for use in patients with severe kidney impairment or kidneys not producing any urine. It should be used with caution in patients having renal artery stenosis (narrowing of renal arteries) or functioning of one kidney or having had a recent kidney transplant. Consult your doctor before taking Osartil 50 Plus.
Osartil 50 Plus is not recommended for use in patients with severe liver impairment. It should be used with caution in patients having a history of mild to moderate liver impairment. Consult your doctor before taking Osartil 50 Plus.
Osartil 50 Plus displaces angiotensin II with a very high affinity from its binding site at the AT1 receptor subtype, which is responsible for the known actions of angiotensin II. Hydrochlorothiazide is a diuretic that inhibits a sodium-chloride symporter SLC12A3 in the distal convoluted tubule to inhibit water reabsorption in the nephron. The symporter reabsorbs sodium and creates an osmotic gradient for water to be reabsorbed, the inhibition of which prevents water reabsorption.
There are three main reasons for its usage.
Firstly
Treatment of High Blood Pressure: Osartil 50 Plus is primarily used for the treatment of essential hypertension or high blood pressure. By combining the actions of Losartan, an angiotensin II receptor blocker, and Hydrochlorothiazide, a thiazide diuretic, it helps to lower blood pressure by relaxing blood vessels and increasing urine output.
Secondly
Risk Reduction of Stroke in People with High Blood Pressure and Left Ventricular Hypertrophy (LVH): Left ventricular hypertrophy refers to the enlargement and thickening of the muscle wall of the left ventricle of the heart. Osartil 50 Plus is prescribed to individuals with high blood pressure and LVH to reduce the risk of stroke. By controlling blood pressure and reducing the workload on the heart, Osartil 50 Plus helps decrease the chances of stroke occurrence.
Lastly
Treatment of Diabetic Nephropathy: Diabetic nephropathy is a kidney disease caused by diabetes. Osartil 50 Plus is also used in the management of this condition. Diabetes can damage the small blood vessels in the kidneys, leading to impaired kidney function. Osartil 50 Plus helps protect the kidneys by lowering blood pressure and reducing the strain on the renal system.
Angiotensin II is formed from angiotensin I through the action of an enzyme called angiotensin-converting enzyme (ACE). Angiotensin II is a potent vasoconstrictor and plays a crucial role in the renin-angiotensin system, which is involved in the regulation of blood pressure. It also stimulates the release of aldosterone from the adrenal cortex. Aldosterone promotes sodium and water retention, leading to an increase in blood volume and further elevation of blood pressure.
Losartan, the active component of Osartil 50 Plus, and its primary metabolite act by blocking the effects of angiotensin II at its receptor sites. Specifically, they selectively block the binding of angiotensin II to the AT1 receptor, which is found in various tissues such as vascular smooth muscle and the adrenal gland. By inhibiting the actions of angiotensin II, losartan helps to relax and widen blood vessels, reducing vasoconstriction and lowering blood pressure. It also decreases aldosterone secretion, leading to reduced sodium and water retention.
It's important to note that losartan and its metabolite do not inhibit the enzyme ACE (kinase II), which is responsible for converting angiotensin I to angiotensin II. Additionally, they do not bind to or block other hormone receptors or ion channels known to be involved in cardiovascular control.
Hydrochlorothiazide, the other component of Osartil 50 Plus, is a thiazide diuretic. It acts on the renal tubules to increase the excretion of sodium and chloride, reducing their reabsorption. This leads to increased urine production and a decrease in plasma volume. As a result, plasma renin activity increases, which stimulates the release of aldosterone. Aldosterone, in turn, promotes potassium excretion while increasing sodium and water retention. When Osartil 50 Plus is coadministered with an angiotensin II receptor antagonist like losartan, it can help counteract the potassium loss associated with thiazide diuretics.
The recommended starting dose of Osartil 50 Plus for hypertension is one tablet of 50/12.5 (50 mg of losartan and 12.5 mg of hydrochlorothiazide) taken once daily. This dosage can be increased to one tablet of 100/25 if the blood pressure is not adequately controlled with the lower dose.
For patients with left ventricular hypertrophy, the initial dose is one tablet of 50/12.5. If additional blood pressure reduction is needed, the dosage may be increased to one tablet of 100/12.5. If further control is required, the maximum dose of one tablet of 100/25 once daily may be used.
The antihypertensive effect of Osartil 50 Plus is typically achieved within three weeks after starting the therapy.
For elderly patients, no initial dosage adjustment is necessary for the 50/12.5 dose. However, the maximum dose of 100/25 should not be used as initial therapy in elderly patients.
In cases of severe hypertension, the starting dose is one tablet of 50/12.5 once daily. If the response is insufficient after 2 to 4 weeks, the dosage can be increased to one tablet of 100/25 once daily. The maximum recommended dose is one tablet of 100/25 once daily.
Osartil 50 Plus can be used in combination with other antihypertensive medications if needed. It can be taken with or without food. It is important to follow your physician's instructions regarding the correct dose and duration of treatment, as they will consider factors such as your age, body weight, and the specific condition being treated.
Remember to swallow Osartil 50 Plus tablets with a glass of water and avoid crushing or chewing them.
Alcohol: Consumption of alcohol while taking Osartil 50 Plus can lower blood pressure and may cause dizziness, headache, and changes in heart rate. It is advisable to avoid driving or operating heavy machinery if you experience these symptoms.
Interaction with other Medicines:
Interaction with Disease:
Angiotensin II receptor antagonists, including losartan (the active component of Osartil 50 Plus), are generally not recommended for use during pregnancy. They have been associated with adverse effects on prenatal and newborn blood pressure regulation and renal function. Additionally, there have been reports of skull abnormalities and oligohydramnios (reduced amniotic fluid) associated with their use.
Regarding breastfeeding, there is limited information available on the use of angiotensin II receptor antagonists during this period. As a precautionary measure, they are not recommended for use while nursing. It is important to note that there are alternative treatment options with better-established safety information that can be considered for breastfeeding mothers.
Store Osartil 50 Plus tablet below 30°C protected from light and moisture. Keep away from children and pets.
