USE IN PREGNANCY
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. When pregnancy is detected, losartan potassium and hydrochlorothiazide tablets should be discontinued as soon as possible (see WARNINGS, Fetal/Neonatal Morbidity and Mortality).
Losartan potassium and hydrochlorothiazide tablets 50 mg/ 12.5 mg and losartan potassium and hydrochlorothiazide tablets 100 mg/ 25 mg combine an angiotensin II receptor (type AT1) antagonist and a diuretic, hydrochlorothiazide.
Losartan potassium, a non-peptide molecule, is chemically described as 2-butyl-4-chloro-1-[p-(o-1H-tetrazol-5-ylphenyl)benzyl]imidazole-5-methanol monopotassium salt. Its molecular formula is C22H22ClKN6O, and its structural formula is:
Losartan potassium, USP is off-white to creamish-yellow powder with a molecular weight of 461.01. It is soluble in water.
Oxidation of the 5-hydroxymethyl group on the imidazole ring results in the active metabolite of losartan.
Hydrochlorothiazide is 6-chloro-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its molecular formula is C7H8ClN3O4S2 and its structural formula is:
Hydrochlorothiazide, USP is a white or practically white, practically odorless crystalline powder with a molecular weight of 297.74. It is slightly soluble in water; freely soluble in sodium hydroxide solution, in n-butylamine, and in dimethylformamide, sparingly soluble in methanol; insoluble in ether, in chloroform, and in dilute mineral acids.
Each losartan potassium and hydrochlorothiazide tablet intended for oral administration contains losartan potassium, 50 mg or 100 mg and hydrochlorothiazide, 12.5 mg or 25 mg. In addition, each tablet also contains the following inactive ingredients: colloidal silica anhydrous, hydroxypropyl cellulose (low substituted), hydroxypropyl methylcellulose, lactose monohydrate, magnesium stearate, maize starch, microcrystalline cellulose, polyethylene glycol, sodium starch glycolate, talc and titanium dioxide.
Losartan potassium and hydrochlorothiazide tablet 50 mg/ 12.5 mg contains 4.24 mg (0.108 mEq) of potassium and losartan potassium and hydrochlorothiazide tablet 100 mg/ 25 mg contains 8.48 mg (0.216 mEq) of potassium.
Losartan potassium and hydrochlorothiazide has been evaluated for safety in 858 patients treated for essential hypertension and 3889 patients treated for hypertension and left ventricular hypertrophy. In clinical trials with losartan potassium and hydrochlorothiazide, no adverse experiences peculiar to this combination have been observed. Adverse experiences have been limited to those that were reported previously with losartan potassium and/or hydrochlorothiazide. The overall incidence of adverse experiences reported with the combination was comparable to placebo.
In general, treatment with losartan potassium and hydrochlorothiazide was well tolerated. For the most part, adverse experiences have been mild and transient in nature and have not required discontinuation of therapy. In controlled clinical trials, discontinuation of therapy due to clinical adverse experiences was required in only 2.8% and 2.3% of patients treated with the combination and placebo, respectively.
In these double-blind controlled clinical trials, the following adverse experiences reported with losartan-hydrochlorothiazide occurred in ≥1 percent of patients, and more often on drug than placebo, regardless of drug relationship:
Losartan Potassium and Hydrochlorothiazide
Body as a Whole
The following adverse events were also reported at a rate of 1 % or greater, but were as, or more, common in the placebo group in studies of essential hypertension: asthenia/fatigue, diarrhea, nausea, headache, bronchitis, pharyngitis.
Adverse events occurred at about the same rates in men and women. Adverse events were somewhat more frequent in the elderly compared to non-elderly patients and somewhat more frequent in Blacks compared to non-Blacks for both the losartan and hydrochlorothiazide and the control groups.
A patient with known hypersensitivity to aspirin and penicillin, when treated with losartan potassium, was withdrawn from study due to swelling of the lips and eyelids and facial rash, reported as angioedema, which returned to normal 5 days after therapy was discontinued.
Superficial peeling of palms and hemolysis were reported in one subject treated with losartan potassium.
Other adverse experiences that have been reported with losartan, without regard to causality, are listed below:

Persistent dry cough (with an incidence of a few percent) has been associated with ACE-inhibitor use and in practice can be a cause of discontinuation of ACE-inhibitor therapy. Two prospective, parallel-group, double-blind, randomized, controlled trials were conducted to assess the effects of losartan on the incidence of cough in hypertensive patients who had experienced cough while receiving ACE-inhibitor therapy. Patients who had typical ACE-inhibitor cough when challenged with lisinopril, whose cough disappeared on placebo, were randomized to losartan 50 mg, lisinopril 20 mg, or either placebo (one study, n=97) or 25 mg hydrochlorothiazide (n=135). The double-blind treatment period lasted up to 8 weeks. The incidence of cough is shown below.
Study 1† HCTZ Losartan Lisinopril
Cough 25% 17% 69%
Study 2†† Placebo Losartan Lisinopril
Cough 35% 29% 62%
† Demographics = (89% caucasian, 64% female)
†† Demographics = (90% caucasian, 51% female)
These studies demonstrate that the incidence of cough associated with losartan therapy, in a population that all had cough associated with ACE-inhibitor therapy, is similar to that associated with hydrochlorothiazide or placebo therapy.
Cases of cough, including positive re-challenges, have been reported with the use of losartan in post-marketing experience.
In a clinical study in patients with severe hypertension (SiDBP ≥110 mmHg), the overall pattern of adverse events reported through six weeks of follow-up was similar in patients treated with losartan potassium and hydrochlorothiazide tablets as initial therapy and in patients treated with losartan as initial therapy. There were no reported cases of syncope in either treatment group. There were 2 (0.6%) and 0 (0.0%) cases of hypotension reported in the group treated with losartan potassium and hydrochlorothiazide tablets and the group treated with losartan, respectively. There were 3 (0.8%) and 2 (1.2%) cases of increased serum creatinine (>0.5 mg/dL) in the group treated with losartan potassium and hydrochlorothiazide tablets and the group treated with losartan, respectively, during the same time period (see CLINICAL PHARMACOLOGY, Pharmacodynamics and Clinical Effects, Severe Hypertension).
The following additional adverse reactions have been reported in post-marketing experience:
Digestive: Hepatitis has been reported rarely in patients treated with losartan.
Hypersensitivity: Angioedema, including swelling of the larynx and glottis, causing airway obstruction and/or swelling of the face, lips, pharynx, and/or tongue has been reported rarely in patients treated with losartan; some of these patients previously experienced angioedema with other drugs including ACE inhibitors. Vasculitis, including Henoch-Schonlein purpura, has been reported with losartan. Anaphylactic reactions have been reported.
Metabolic and Nutrition: Hyperkalemia, hyponatremia have been reported with losartan.
Musculoskeletal: Rare cases of rhabdomyolysis have been reported in patients receiving angiotensin II receptor blockers.
Respiratory: Dry cough (see above) has been reported with losartan.
Skin: Erythroderma has been reported with losartan.
Laboratory Test Findings:
In controlled clinical trials, clinically important changes in standard laboratory parameters were rarely associated with administration of losartan potassium and hydrochlorothiazide tablets.
Creatinine, Blood Urea Nitrogen:
Minor increases in blood urea nitrogen (BUN) or serum creatinine were observed in 0.6 and 0.8 percent, respectively, of patients with essential hypertension treated with losartan potassium and hydrochlorothiazide tablets alone. No patient discontinued taking losartan potassium and hydrochlorothiazide tablets due to increased BUN. One patient discontinued taking losartan potassium and hydrochlorothiazide tablets due to a minor increase in serum creatinine.
Hemoglobin and Hematocrit:
Small decreases in hemoglobin and hematocrit (mean decreases of approximately 0.14 grams percent and 0.72 volume percent, respectively) occurred frequently in patients treated with losartan potassium and hydrochlorothiazide tablets alone, but were rarely of clinical importance. No patients were discontinued due to anemia.
Liver Function Tests:
Occasional elevations of liver enzymes and/or serum bilirubin have occurred. In patients with essential hypertension treated with losartan potassium and hydrochlorothiazide tablets alone, no patients were discontinued due to these laboratory adverse experiences.

High Blood Pressure (hypertension) Blood pressure is the force in your blood vessels when your heart beats and when your heart rests. You have high blood pressure when the force is too much. The losartan ingredient in losartan potassium and hydrochlorothiazide tablet can help your blood vessels relax so your blood pressure is lower. The hydrochlorothiazide ingredient in losartan potassium and hydrochlorothiazide tablet works by making your kidneys pass more water and salt.
Left Ventricular Hypertrophy (LVH) is an enlargement of the walls of the left chamber of the heart (the heart’s main pumping chamber). LVH can happen from several things. High blood pressure is the most common cause of LVH.
