Insyten
Insyten Uses, Dosage, Side Effects, Food Interaction and all others data.
Insyten is a diuretic antihypertensive. It appears to cause vasodilation, probably by inhibiting the passage of calcium and other ions (sodium, potassium) across membranes. It has an extra-renal antihypertensive action resulting in a decrease in vascular hyperreactivity and a reduction in total peripheral and arteriolar resistance.
Classified as a sulfonamide diuretic, indapamide is an effective antihypertensive agent and by extension, has shown efficacy in the prevention of target organ damage.Administration of indapamide produces water and electrolyte loss, with higher doses associated with increased diuresis. Severe and clinically significant electrolyte disturbances may occur with indapamide use - for example, hypokalemia resulting from renal potassium loss may lead to QTc prolongation. Further electrolyte imbalances may occur due to renal excretion of sodium, chloride, and magnesium.
Other indapamide induced changes include increases in plasma renin and aldosterone, and reduced calcium excretion in the urine. In many studies investigating the effects of indapamide in both non-diabetic and diabetic hypertensive patients, glucose tolerance was not significantly altered. However, additional studies are necessary to assess the long term metabolic impacts of indapamide, since thiazide related impaired glucose tolerance can take several years to develop in non-diabetic patients.

Uses
Insyten is used for the treatment of essential hypertension . It is effective in treating hypertension in patients with renal function impairment, although its diuretic effect is reduced. Insyten is also used for the treatment of salt and fluid retention associated with congestive heart failure.
Insyten is also used to associated treatment for these conditions: High Blood Pressure (Hypertension), Recurrent Nephrolithiasis, Sodium and fluid retention
How Insyten works
Insyten acts on the nephron, specifically at the proximal segment of the distal convoluted tubule where it inhibits the Na+/Cl- cotransporter, leading to reduced sodium reabsorption. As a result, sodium and water are retained in the lumen of the nephron for urinary excretion. The effects that follow include reduced plasma volume, reduced venous return, lower cardiac output, and ultimately decreased blood pressure.
Interestingly, it is likely that thiazide-like diuretics such as indapamide have additional blood pressure lowering mechanisms that are unrelated to diuresis. This is exemplified by the observation that the antihypertensive effects of thiazides are sustained 4-6 weeks after initiation of therapy, despite recovering plasma and extracellular fluid volumes.
Some studies have suggested that indapamide may decrease responsiveness to pressor agents while others have suggested it can decrease peripheral resistance. Although it is clear that diuresis contributes to the antihypertensive effects of indapamide, further studies are needed to investigate the medication’s ability to decrease peripheral vascular resistance and relax vascular smooth muscle.
Dosage
Insyten dosage
One tablet daily preferably in the morning. In more sever case Insyten can be combine with other categories of anti-hypertensive agent. The safety and effectiveness in pediatric patients have not been established
Side Effects
Side effects of Insyten include headache, anorexia, gastric irritation,nausea, vomiting, constipation, diarrhoea etc.
Toxicity
Insyten overdose symptoms may include but are not limited to nausea, vomiting, gastrointestinal disorders, electrolyte disturbances and weakness. Other signs of overdose include respiratory depression and severe hypotension. In cases of overdose, supportive care interventions may be necessary to manage symptoms. Emesis and gastric lavage may be recommended to empty the stomach; however, patients should be monitored closely for any electrolyte or fluid imbalances.
Precaution
Monitoring of potassium and uric acid serum levels is recommended, especially in subjects with a predisposition or sensitivity to hypokalemia and in patients with gout. Although no allergic manifestations have been reported during clinical trials, patients with a history of allergy to sulfonamide derivatives should be closely monitored.
Interaction
Other antihypertensive: Insyten may add to or potentiate the action of other antihypertensive drugs.
Norepinephrine: Insyten like thiazides, may decrease arterial responsiveness to norepinephrine.
Lithium: In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity.
Food Interaction
- Avoid alcohol. Alcohol may potentiate orthostatic hypotension.
- Increase consumption of potassium-rich foods. Insyten my cause potassium depletion leading to hypokalemia.
- Take with or without food.
Insyten Alcohol interaction
[Moderate]
Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation.
Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
Caution and close monitoring for development of hypotension is advised during coadministration of these agents.
Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs.
Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
Insyten Cholesterol interaction
[Moderate] Thiazide diuretics may increase serum triglyceride and cholesterol levels, primarily LDL and VLDL.
Whether these effects are dose-related and sustained during chronic therapy are unknown.
Patients with preexisting hyperlipidemia may require closer monitoring during thiazide therapy, and adjustments made accordingly in their lipid-lowering regimen
Insyten Drug Interaction

Insyten Disease Interaction
Major: anuria, electrolyte losses, liver disease, lupus erythematosus, renal function disordersModerate: asthma, diabetes, hyperlipidemia, hyperparathyroidism, hyperuricemia, thyroid function tests
Volume of Distribution
Some sources report an apparent volume of distribution of 25 L for indapamide, while others report a value of approximately 60 L.
Elimination Route
The bioavailability of indapamide is virtually complete after an oral dose and is unaffected by food or antacids. Insyten is highly lipid-soluble due to its indoline moiety - a characteristic that likely explains why indapamide’s renal clearance makes up less than 10% of its total systemic clearance. The Tmax occurs approximately 2.3 hours after oral administration. The Cmax and AUC0-24 values are 263 ng/mL and 2.95 ug/hr/mL, respectively.
Half Life
Insyten is characterized by biphasic elimination. In healthy subjects, indapamide's elimination half-life can range from 13.9 to 18 hours. The long half-life is conducive to once-daily dosing.
Clearance
Insyten's renal and hepatic clearance values are reported to be 1.71 mL/min and 20-23.4 mL/min, respectively.
Elimination Route
An estimated 60-70% of indapamide is eliminated in the urine, while 16-23% is eliminated in the feces.
Pregnancy & Breastfeeding use
There are no adequate and well-controlled studies in pregnant women and so Insyten is not recommended. Mothers taking Insyten should not breast feed.
Contraindication

- Hypersensitivity to sulfonamides
