Lisinopril and hydrochlorothiazide tablets combines an angiotensin converting enzyme inhibitor, lisinopril, and a diuretic, hydrochlorothiazide.

Lisinopril, a synthetic peptide derivative, is an oral long-acting angiotensin converting enzyme inhibitor. It is chemically described as (S)-1-[N2-(1-carboxy-3-phenylpropyl)-L-lysyl]-L-proline dihydrate. Its empirical formula is C₂₁H₃₁N₃O₅•2H2O and its structural formula is: Lisinopril is a white to off-white, crystalline powder, with a molecular weight of 441.52. It is soluble in water, sparingly soluble in methanol, and practically insoluble in ethanol.

Hydrochlorothiazide is 6-chloro-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its empirical formula is C₇H₈ClN₃O₄S₂ and its structural formula is: Hydrochlorothiazide is a white, or practically white, crystalline powder with a molecular weight of 297.73, which is slightly soluble in water, but freely soluble in sodium hydroxide solution.

Lisinopril and hydrochlorothiazide tablets are available for oral use in three tablet combinations of lisinopril with hydrochlorothiazide: lisinopril and hydrochlorothiazide tablets 10 mg/12.5 mg, containing 10 mg lisinopril and 12.5 mg hydrochlorothiazide, lisinopril and hydrochlorothiazide tablets 20 mg/12.5 mg, containing 20 mg lisinopril and 12.5 mg hydrochlorothiazide and lisinopril and hydrochlorothiazide tablets 20 mg/25 mg, containing 20 mg lisinopril and 25 mg hydrochlorothiazide.

Inactive ingredients are dibasic calcium phosphate, magnesium stearate, mannitol, pregelatinized starch and starch. Lisinopril and hydrochlorothiazide tablets 10 mg/12.5 mg also contains FD and C Blue No. 2 Aluminum Lake. Lisinopril and hydrochlorothiazide tablets 20 mg/12.5 mg also contains yellow iron oxide and lisinopril and hydrochlorothiazide tablets 20 mg/25 mg also contain red iron oxide.

INDICATIONS AND USAGE

id: 43445109-1656-4ea8-9924-6b512dea604a
displayName: INDICATIONS & USAGE SECTION
FDA Article Code: 34067-9

Lisinopril and hydrochlorothiazide tablets are indicated for the treatment of hypertension.

These fixed-dose combinations are not indicated for initial therapy (see  DOSAGE AND   ADMINISTRATION).

In using lisinopril and hydrochlorothiazide tablets, consideration should be given to the fact that an angiotensin converting enzyme inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen vascular disease, and that available data are insufficient to show that lisinopril does not have a similar risk. (See  WARNINGS.)

In considering use of lisinopril and hydrochlorothiazide tablets, it should be noted that Black patients receiving ACE inhibitors have been reported to have a higher incidence of angioedema compared to non-Blacks. (See  WARNINGS, Head and Neck Angioedema.)

CONTRAINDICATIONS

id: df436246-5823-488d-80f0-a1ebaa26ff63
displayName: CONTRAINDICATIONS SECTION
FDA Article Code: 34070-3

Lisinopril and hydrochlorothiazide is contraindicated in patients who are hypersensitive to any component of this product and in patients with a history of angioedema related to previous treatment with an angiotensin converting enzyme inhibitor and in patients with hereditary or idiopathic angioedema. Because of the hydrochlorothiazide component, this product is contraindicated in patients with anuria or hypersensitivity to other sulfonamide-derived drugs.

ADVERSE REACTIONS

id: 96ca606e-f25d-4e3c-809c-33fa2431fb6e
displayName: ADVERSE REACTIONS SECTION
FDA Article Code: 34084-4

Lisinopril and hydrochlorothiazide has been evaluated for safety in 930 patients, including 100 patients treated for 50 weeks or more.

In clinical trials with lisinopril and hydrochlorothiazide no adverse experiences peculiar to this combination drug have been observed. Adverse experiences that have occurred have been limited to those that have been previously reported with lisinopril or hydrochlorothiazide.

The most frequent clinical adverse experiences in controlled trials (including open label extensions) with any combination of lisinopril and hydrochlorothiazide were: dizziness (7.5 percent), headache (5.2 percent), cough (3.9 percent), fatigue (3.7 percent) and orthostatic effects (3.2 percent), all of which were more common than in placebo-treated patients. Generally, adverse experiences were mild and transient in nature; but see  WARNINGSregarding angioedema and excessive hypotension or syncope. Discontinuation of therapy due to adverse effects was required in 4.4 percent of patients, principally because of dizziness, cough, fatigue and muscle cramps.

Adverse experiences occurring in greater than one percent of patients treated with lisinopril plus hydrochlorothiazide in controlled clinical trials are shown below. Percent of Patients in Controlled Studies

Clinical adverse experiences occurring in 0.3 to 1.0 percent of patients in controlled trials included: Body as a Whole: Chest pain, abdominal pain, syncope, chest discomfort, fever, trauma, virus infection. Cardiovascular: Palpitation, orthostatic hypotension. Digestive: Gastrointestinal cramps, dry mouth, constipation, heartburn. Musculoskeletal: Back pain, shoulder pain, knee pain, back strain, myalgia, foot pain. Nervous/Psychiatric: Decreased libido, vertigo, depression, somnolence. Respiratory: Common cold, nasal congestion, influenza, bronchitis, pharyngeal pain, dyspnea, pulmonary congestion, chronic sinusitis, allergic rhinitis, pharyngeal discomfort. Skin: Flushing, pruritus, skin inflammation, diaphoresis. Special Senses: Blurred vision, tinnitus, otalgia. Urogenital: Urinary tract infection.

Angioedema: Angioedema has been reported in patients receiving lisinopril and hydrochlorothiazide, with an incidence higher in Black than in non-Black patients. Angioedema associated with laryngeal edema may be fatal. If angioedema of the face, extremities, lips, tongue, glottis and/or larynx occurs, treatment with lisinopril and hydrochlorothiazide should be discontinued and appropriate therapy instituted immediately. In rare cases, intestinal angioedema has been reported with angiotensin converting enzyme inhibitors including lisinopril. (See  WARNINGS.)

Hypotension: In clinical trials, adverse effects relating to hypotension occurred as follows: hypotension (1.4), orthostatic hypotension (0.5), other orthostatic effects (3.2). In addition syncope occurred in 0.8 percent of patients. (See  WARNINGS.)

Cough: See  PRECAUTIONS, Cough.

OVERDOSAGE

id: 61e15158-0b53-429c-99e0-3414dce97e52
displayName: OVERDOSAGE SECTION
FDA Article Code: 34088-5

No specific information is available on the treatment of overdosage with lisinopril and hydrochlorothiazide. Treatment is symptomatic and supportive. Therapy with lisinopril and hydrochlorothiazide should be discontinued and the patient observed closely. Suggested measures include induction of emesis and/or gastric lavage, and correction of dehydration, electrolyte imbalance and hypotension by established procedures.

DOSAGE AND ADMINISTRATION

id: 36e7f125-35ab-4bad-b9ad-21a9c4e28464
displayName: DOSAGE & ADMINISTRATION SECTION
FDA Article Code: 34068-7

Lisinopril is an effective treatment of hypertension in once-daily doses of 10 to 80 mg, while hydrochlorothiazide is effective in doses of 12.5 to 50 mg. In clinical trials of lisinopril/hydrochlorothiazide combination therapy using lisinopril doses of 10 to 80 mg and hydrochlorothiazide doses of 6.25 to 50 mg, the antihypertensive response rates generally increased with increasing dose of either component.

The side effects (see  WARNINGS) of lisinopril are generally rare and apparently independent of dose; those of hydrochlorothiazide are a mixture of dose-dependent phenomena (primarily hypokalemia) and dose-independent phenomena (e.g., pancreatitis), the former much more common than the latter. Therapy with any combination of lisinopril and hydrochlorothiazide will be associated with both sets of dose-independent side effects, but addition of lisinopril in clinical trials blunted the hypokalemia normally seen with diuretics.

To minimize dose-independent side effects, it is usually appropriate to begin combination therapy only after a patient has failed to achieve the desired effect with monotherapy.
