Description
S (-) Amlodipine, the chirally pure form of Amlodipine is a calcium channel antagonist belonging to the dihydropyridine class. Hydrochlorothiazide is a diuretic which produces the antihypertensive activity.
Rationale of Combination
The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) states that drug treatment for hypertension should begin with a thiazide-type diuretic in most patients, either alone or in combination with an ACE inhibitor, an ARB, or a CCB. Various studies have been conducted using calcium channel blockers along with the Hydrochlorothiazide and the combination has found to be superior than the individual drugs and there are no adverse drug interactions recorded with the usage of the combination. Therefore combination of S (-) Amlodipine along with a thiazide diuretic is a rationale combination which can be used as a first line treatment of the hypertension.
Clinical Pharmacology
S (-) Amlodipine, the chirally pure form of Amlodipine is a calcium channel antagonist belonging to the dihydropyridine class. The S (-) isomer of Amlodipine is found to possess greater pharmacological effects than R (+) Amlodipine. S (-) Amlodipine is 1000 times more potent than the R (+) isomer in binding to the dihydropyridine receptor. Therefore this is the only form which produces its therapeutic effects. In humans, the dominant effects of Amlodipine are consequent to vasodilation. S (-) Amlodipine lowers peripheral vascular resistance without causing a reflex tachycardia. In patients with angina pectoris S (-) Amlodipine reduces the myocardial oxygen demand by causing a direct vasodilation of the coronary artery and arterioles. Thiazides are moderately potent diuretics and exert their diuretic effect by reducing the reabsorption of electrolytes from the renal tubules, thereby increasing the excretion of Sodium and Chloride ions, and consequently of water. They act mainly at the beginning of the distal tubules. They also reduce carbonic-anhydrase activity so that bicarbonate excretion is increased, but this effect is generally small compared with the effect on Chloride excretion and does not appreciably alter the pH of the urine. Their hypotensive effect is probably partly due to a reduction in peripheral resistance : they also enhance the effects of other antihypertensives.
Pharmacokinetics
Administration of S (-) Amlodipine 2.5 mg as a single dose in the fasting state produced maximum plasma concentration (Cmax) of 8.30 ± 1.071 ng/ ml in 2.73 ± 0.88 hrs. (Tmax). Amlodipine is extensively (about 90%) converted to inactive metabolites via hepatic metabolism with 10% of the parent compound and 60% of the metabolites excreted in the urine. Ex vivo studies have shown that approximately 93% of the circulating drug is bound to plasma proteins in hypertensive patients. The mean AUC0-t value (t = 48 hrs.) of S (-) Amlodipine (2.5 mg) is 95.33 ± 14.45 ng.hr/ml. The AUC0-∞ value is recorded to be 140.91± 28.06 ng.hr/ml. The plasma elimination half life of S (-) Amlodipine has been found to be 31.09 ± 12.65 hrs. Hydrochlorothiazide is fairly rapidly absorbed from the gastrointestinal tract. It is reported to have a bioavailability of about 65 to 70%. It has been estimated to have a plasma half-life of between about 5 and 15 hours and appears to be preferentially bound to red blood cells. It is excreted mainly unchanged in the urine. Hydrochlorothiazide crossed the placental barrier and is distributed into breast milk.
Indications
For the treatment of mild to moderate hypertension.
Contraindications
Hypersensitivity to any of the components listed in the formulation
Dosage and Administration:
One tablet to be administered once daily
Overdosage
There are no reported cases of overdosage with the use of S (-) Amlodipine. Overdosage with racemic Amlodipine may cause excessive peripheral vasodilation with marked hypotension and possibly a reflex tachycardia. Hence, caution should be taken in case of an overdosage with S (-) Amlodipine. If massive overdose occurs, active cardiac and respiratory monitoring should be instituted. Frequent blood pressure measurements should be performed. Should hypotension occur, cardiovascular support including elevation of the extremities and the judicious administration of fluids should be initiated. If hypotension remains unresponsive to these conservative measures, administration of vasopressors (such as phenylephrine) should be considered with attention to circulating. If massive overdose occurs, gastric lavage should be employed. As this product is highly plasma protein bound, hemodialysis is not likely to be of benefit. Electrolyte depletion (hypokalaemia, hypochloremia, hyponatraemia) and dehydration are the most common signs and symptoms of Hydrochlorothiazide overdosage. If digitalis has been administered, hypokalaemia may accentuate cardiac arrhythmias. The plasma half-life of Hydrochlorothiazide is 5.6 hours with a subsequent longer terminal half-life. Treatment should be symptomatic and supportive. Therapy should be discontinued and the patient watched closely.
Adverse Reactions
S (-) Amlodipine : Gingival Hypertrophy and Alopecia has been seen with S (-) Amlodipine. On the basis of the clinical data available, only minor side effects have been reported with the use of S (-) Amlodipine. Adverse events reported in less than 5% of the patients included anxiety (0.43%), anorexia (0.43%), irritation (0.43%), headache (2.13%) and facial flushing (2.13%). Caution should be exercised when administering S (-) Amlodipine to patients with impaired hepatic and renal function. Hydrochlorothiazide : Common adverse events seen with Hydrochlorothiazide are as follows : fever, necrotising angiitis (vasculitis, cutaneous vasculitis), jaundice (intrahepatic cholestatic jaundice), pancreatitis, cramping, gastric irritation, glycosuria, hyperglycaemia, hyperuricaemia, hypokalaemia, photosensitivity, sialadenitis, urticaria, toxic epidermal necrolysis, agranulocytosis, aplastic anaemia, haemolytic anaemia, leucopenia, purpura, thrombocytopenia, restlessness, interstitial nephritisrespiratory distress, including pneumonitis, pulmonary oedema, transient blurred vision, xanthopsia, non-melanoma skin cancer (Basal cell carcinoma and Squamous cell carcinoma).
Precautions
Hepatic impairment and renal impairment : No controlled clinical study of S (-) Amlodipine has been performed in patients with hepatic impairment and renal impairment. Clinical studies in patients with normal liver function have shown that there is no elevation in the hepatic enzymes with the use of S (-) Amlodipine. Approximately 90% of S (-) Amlodipine is metabolised in liver therefore a careful dosage adjustment should be considered in cases of hepatic impairment. Since about 10% of the S (-) Amlodipine is excreted unchanged in urine, no dosage adjustment is required in patients with renal impairment. Hydrochlorothiazide should be avoided in patients with severe hepatic impairment, in whom encephalopathy may be precipitated. Diuretics should be given with caution in patients with renal impairment, since they can further reduce renal impairment.
Special Population
Pregnant Women & Nursing Mothers : There is no data available on the use of S (-) Amlodipine in pregnant and lactating women. Hydrochlorothiazide may cross placenta, and there have been reports of neonatal jaundice, thrombocytopenia and electrolyte imbalance following maternal use. Treatment with large doses may inhibit lactation.
Since there are no studies available on the use of the combination in pregnant women, it should be administered only when the potential benefits outweighs the risk to the patient.
Children : Safety and effectiveness of this product in children has not been established.
Drug Interactions
Clinical studies have shown that S (-) Amlodipine when combined with aspirin, nitrates, beta-blockers, statins, ACE inhibitors, H2 blockers, and Proton Pump Inhibitors produced no drug interactions. Usual side effects of S (-) Amlodipine given alone and Hydrochlorothiazide given alone can be expected with the combination, but no known enhancement of the side effect has been observed in the published literature with the combination.
Storage
Store below 30°C. Protect from light & moisture.
Keep out of reach of children.

1. What Eslo D® is and what it is used for
Eslo D® contains two substances called S (-) Amlodipine and Hydrochlorothiazide. Both of these substances help to control high blood pressure.
Amlodipine belongs to a group of substances called “calcium channel blockers”. Amlodipine also lowers blood pressure by relaxing blood vessels.
Hydrochlorothiazide is one of a group of medicines called thiazide diuretics (“water tablets”). It lowers blood pressure by helping the body to get rid of extra fluid by making your kidneys produce more urine.
The actions of these two substances contribute to decreasing your blood pressure.
Thus, Eslo D® is used to treat high blood pressure.
2. What you need to know before you take Eslo D®
Do not take Eslo D®:
if you are allergic to S(-)Amlodipine, amlodipine, Hydrochlorothiazide, any drug of a related class, or any of the other ingredients of this medicine (listed in section 6).
If you think you may be allergic, talk to your doctor before taking Eslo D®.
if you have severe liver problems or bile problems such as biliary cirrhosis or cholestasis.
If you have severe kidney problems.
if you are more than 3 months pregnant. (It is also better to avoid Eslo D® in early pregnancy, see Pregnancy section).
if you have severe low blood pressure (hypotension).
If the blood flow from your heart is slow or blocked.
This may happen if the blood vessel or valve that takes blood away from your heart becomes narrow (aortic stenosis).
you have a low heart output after a heart attack (acute myocardial infarction).
Low heart output may make you feel short of breath or have swelling in your feet and ankles.
if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren.
If any of the above applies to you, do not take Eslo D® and talk to your doctor.
Warnings and precautions
Talk to your doctor before taking Eslo D® Tablets:
if you have been sick (vomiting or diarrhoea).
if you have liver or kidney problems.
if you have had a kidney transplant or if you had been told that you have a narrowing of your kidney arteries.
if you have a condition affecting the renal glands called “primary hyperaldosteronism”.
if you have had heart failure or have experienced a heart attack.
Follow your doctor’s instructions for the starting dose carefully.
Your doctor may also check your kidney function.
Skin reactions such as sunburn or rash after being in the sun or using a sunbed.
If you have had skin cancer or if you develop an unexpected skin lesion during the treatment.
Treatment with hydrochlorothiazide, particularly long-term use with high doses, may increase the risk of some types of skin and lip cancer (non-melanoma skin cancer).
Protect your skin from sun exposure and UV rays while taking Sevikar HCT.
if your doctor has told you that you have a narrowing of the valves in your heart (called “aortic or mitral stenosis”) or that the thickness of your heart muscle is abnormally increased (called “obstructive hypertrophic cardiomyopathy”).
if you have experienced swelling, particularly of the face and throat while taking other medicines (including angiotensin-converting enzyme inhibitors).
If you get these symptoms, stop taking Eslo D® and contact your doctor straight away.
You should never take Eslo D® again.
if you are taking any of the following medicines used to treat high blood pressure:
- an ACE inhibitor (for example enalapril, lisinopril, ramipril), in particular if you have diabetes-related kidney problems.
- aliskiren.
Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium) in your blood at regular intervals.
See also information under the heading “Do not take Eslo D®”.
If any of these apply to you, tell your doctor before taking Eslo D®.
Children and adolescents
The use of Eslo D® in children and adolescents is not recommended (aged below 18 years old).

Eslo D® Tablets with food and drink
Grapefruit juice and grapefruit should not be consumed by people who are taking Eslo D® Tablets. This is because grapefruit and grapefruit juice can lead to an increase in the blood levels of the active ingredient S(-)Amlodipine, which can cause an unpredictable increase in the blood pressure-lowering effect of S(-)Amlodipine.
Pregnancy, breast-feeding and fertility
Pregnancy
You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking Eslo D® before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Eslo D®. Eslo D® is not recommended in early pregnancy (first 3 months), and must not be taken when more than 3 months pregnant.
Breast-feeding
Tell your doctor if you are breast-feeding or about to start breast-feeding. Eslo D® is not recommended for mothers who are breastfeeding, and your doctor may choose another treatment for you if you wish to breastfeed, especially if your baby is a newborn or was born prematurely. Ask your doctor or pharmacist for advice before taking any medicine.
