1 Blood pressure continues to fall until 22-24 weeks when a nadir is reached
Calcium ions regulate smooth muscle contractions contributing to inotropic and chronotropic activity in the heart (Rosendorff et al 2007)
Despite the differences in guidelines, there appears to be consensus that severe Nifedipine (modified release) Consider nifedipine for pregnant women in whom labetalol is not suitable; May inhibit labour; manufacturer advises avoid before week 20, but risk to foetus should be balanced against risk of uncontrolled maternal hypertension Gestational hypertension: Between approximately 11 and 15% (up to 1 in 7 women Nifedipine controlled release: Calcium channel antagonist: 30 mg daily - 60 mg twice a day: Headache (first-dose effect), flushing, tachycardia, peripheral oedema Gestational hypertension and pre-eclampsia are associated with a two- to fourfold increase in the future risk of cardiovascular disease
As the most common medical disorder of pregnancy, hypertension is reported to complicate 1 in 10 pregnancies 1,2 and affects an estimated 240 000 women in the United States each year
Headache (first-dose effect), flushing, tachycardia, peripheral oedema Gestational hypertension and pre-eclampsia are associated with a two- to fourfold increase in the future risk of cardiovascular disease
Methodology: A Prospective observational study was conducted in outpatient and inpatient department of Gestational hypertension is defined as new onset BP ≥140 mmHg systolic or 90 mmHg diastolic on at least two occasions, at least 6 h apart, after 20 weeks gestation, in the absence of proteinuria
Role of antihypertensive therapy in mild to moderate pregnancy-induced hypertension: a prospective randomized study High blood pressure, also called hypertension, is very common
Eclampsia may occur in the absence of gestational hypertension or preeclampsia in up to 20% of cases
Extended-release nifedipine, a calcium channel blocker, may be preferred because it is given once a day (initial dose of 30 mg; maximum daily dose of 120 mg); adverse effects include headaches and pretibial edema
However, when pregnancy-induced hypertension is a concern, low placental perfusion causes a decrease in GFR and altered glomerular permeability, resulting in protein loss through the kidneys
Gestational Hypertension Gestational hypertension is defined as a systolic blood pressure 140 mm Hg or more or a diastolic blood pres-sure of 90 mm Hg or more, or both, on two occasions at least 4 hours apart after 20 weeks of gestation, in a woman with a previously normal blood pressure (21)
Methods: A retrospective analysis of the clinical data from 108 patients with gestational hypertension hospitalized between March 2016 and March 2017 was carried out
12669/pjms
Total 118 pregnant women with PIHS who were admitted to our hospital from April 2017 to June 2018 were randomly divided into control group (59 cases) and observation group (59 cases)
Although maternal mortality is much lower in high-income countries than in developing Gestational hypertension, when a pregnant person develops high blood pressure during the second half of her pregnancy Some examples are labetalol, nifedipine, hydralazine, and thiazide diuretics
Nifedipine is the most widely used in pregnancy, preferred as intermediate- or extended The extended-release formulation of nifedipine given once daily provides a relatively constant concentration profile and has proved to be effective in reducing blood pressure values

hypertension with subclinical organ damage or symptoms at any time during pregnancy
Gestational hypertension refers to dysfunction in blood supply to specific organs caused by systemic spasm in micro-arteries, resulting in organ injuries, or even deficiency in blood supply to fetus, which severely threatens the maternal-baby safety (Barden et al
All three oral drugs—methyldopa, nifedipine, and labetalol—are viable initial options for treating severe hypertension in low-resource settings
including gestational hypertension and preeclampsia, that could lead to placental insufficiency and fetal growth restriction
Immediate-release oral nifedipine can cause profound hypotension so its use should be avoided concomitantly with magnesium sulphate, as the potential synergistic action can result in fetal compromise
When a woman presents with severe hypertension lasting at least 15 minutes, antihypertensive treatment, typically with oral nifedipine or intravenous
This guideline covers diagnosing and managing hypertension (high blood pressure), including pre-eclampsia, during pregnancy, labour and birth
Consider nifedipine for women in whom labetalol is not suitable, and methyldopa if labetalol or
Labetalol
Extended-release nifedipine, up to 120 mg daily in women without tachycardia; Methyldopa, two or three times daily up to 3,000 mg per day; or
Nifedipine
3 Antihypertensive treatment rationale in this group represents a departure from the nonpregnant adult Seventh Report of the Joint National Committee on
The non-selective beta blocker labetalol and the calcium channel blocker (CCB) nifedipine have similar efficacy in controlling hypertension during pregnancy and are commonly used due to their good safety profiles
Unstable or acute angina
Methodology: A Prospective observational study was conducted in outpatient and inpatient department of 34% of women in the nifedipine group needed acute hypertension therapy (immediate reduction in blood pressure) compared to 55
Women then being transferred to community care should receive a care plan which outlines: Who will provide follow-up care As the most common medical disorder of pregnancy, hypertension is reported to complicate 1 in 10 pregnancies 1,2 and affects an estimated 240 000 women in the United States each year

Nifedipine: at the time of publication (June 2019), some brands of nifedipine were specifically contraindicated Uncontrolled hypertension can lead to heart failure, myocardial ischemia, renal injury and stroke
Gestational hypertension is blood pressure greater than or equal to 140/90 that begins during the latter half of pregnancy (typically after 20 weeks)
Two recommended that systolic blood pressure ≥160 mmHg and diastolic blood pressure ≥ 105 mmHg should be treated
Long-acting nifedipine: 5 mg IV slowly over 1 to 2 min30–90 mg once daily
