Max / 24h10 mg

PregnancyCategory C

Indications ▼

Hypertension (high blood pressure)

Chronic stable angina

Vasospastic (Prinzmetal) angina

Coronary artery disease adjunct therapy

Mechanism & Pharmacokinetics ▼

Mechanism: Inhibits calcium ion influx into vascular smooth muscle and cardiac muscle, causing vasodilation and reduced blood pressure.

Pharmacokinetics: Oral absorption peak 6–12 hr; extensively metabolized in liver; excreted in urine (~60%) and feces (~10%); half-life ~30–50 hr.

Dosage & Administration ▼

Patient Category	Recommended Dose	Max / 24h
Adults	5–10 mg once daily	10 mg
Elderly	Start 2.5 mg once daily; adjust as needed	10 mg
Children (≥6 yr)	2.5–5 mg once daily	5 mg

Side Effects ▼

Common: Edema, headache, dizziness, fatigue

Occasional: Palpitations, flushing, nausea

Rare: Severe hypotension, hepatic enzyme elevation, angina exacerbation

Contraindications ▼

Hypersensitivity to amlodipine or other dihydropyridine calcium channel blockers

Severe hypotension (systolic BP <90 mmHg)

Shock or unstable angina

Drug Interaction ▼

Simvastatin: may increase statin levels

Grapefruit juice: may increase amlodipine levels

Other antihypertensives: additive hypotensive effect

Pregnancy & Lactation ▼

Use only if clearly needed (Category C)

Excreted in breast milk in small amounts; use with caution

Clinical / Research Summary ▼

Blood Pressure Reduction: Amlodipine effectively lowers both systolic and diastolic blood pressure in hypertensive patients, with gradual onset and sustained 24-hour effect.

Angina Management: Reduces frequency and severity of angina attacks in stable and vasospastic angina.

Cardiovascular Outcomes: Clinical studies show decreased risk of hospitalization for angina and improved outcomes in patients with coronary artery disease.

Pharmacokinetic Advantage: Long half-life allows once-daily dosing, improving adherence.

Safety Profile: Generally well-tolerated; peripheral edema is the most common side effect, usually mild and dose-related.

Current Research Focus: Combination therapy with ACE inhibitors or ARBs, exploring long-term cardiovascular protection, and monitoring metabolic effects in hypertensive populations.

Storage & Handling ▼

Store at 20–25°C; protect from moisture & light

Keep out of reach of children

Patient Counseling Points ▼

How to take: Take once daily, with or without food, preferably at the same time each day.

Missed dose: Take as soon as remembered unless it is near the next dose; do not double dose.

Possible side effects: Peripheral edema, dizziness, flushing, headache; usually mild.

Monitor: Regular blood pressure checks recommended; inform doctor if hypotension or unusual swelling occurs.

Drug interactions: Inform healthcare provider about other medications including statins, antihypertensives, and grapefruit intake.

Lifestyle advice: Maintain low-salt diet, exercise regularly, avoid smoking, limit alcohol to enhance therapy.

Pregnancy and safety: Use during pregnancy or breastfeeding only if advised by physician.

Azelastine HCl + Fluticasone Propionate

Rx Nasal

Therapeutic ClassAntihistamine + Corticosteroid

Dosage FormNasal Spray

Usual Dose1 spray/nostril twice daily

PregnancyCategory C

Indications ▼

Seasonal allergic rhinitis

Perennial allergic rhinitis

Nasal congestion, sneezing, rhinorrhea

Nasal itching and postnasal drip

Patients not adequately controlled with single therapy

Mechanism & Pharmacokinetics ▼

Azelastine: Selective H1-receptor antagonist that blocks histamine-mediated allergic symptoms such as sneezing and itching.

Fluticasone: Corticosteroid that inhibits inflammatory mediators including cytokines, leukotrienes, and prostaglandins.

Combined effect: Provides rapid symptom relief plus long-term anti-inflammatory control.

Absorption: Minimal systemic absorption after intranasal use.

Metabolism: Primarily hepatic via CYP3A4 (fluticasone).

Elimination: Mainly fecal with negligible renal excretion.

Dosage & Administration ▼

Patient	Recommended Dose
Adults & ≥12 years	1 spray in each nostril twice daily
Children <12 years	Not routinely recommended

Shake bottle well before each use.

Prime spray before first use.

Side Effects ▼

Common: Bitter taste, nasal irritation, headache

Occasional: Epistaxis, dryness, sneezing

Rare: Nasal septal perforation, hypersensitivity reactions

Contraindications ▼

Hypersensitivity to azelastine or fluticasone

Untreated nasal infections

Recent nasal surgery or trauma (until healed)

Drug Interaction ▼

Strong CYP3A4 inhibitors may increase fluticasone exposure

Alcohol or sedatives may enhance drowsiness (azelastine)

No major interaction with common antihistamines when used intranasally

Pregnancy & Lactation ▼

Pregnancy Category C

Use only if benefit outweighs potential risk

Minimal systemic absorption reduces fetal exposure

Breastfeeding: use with caution

Clinical / Research Summary ▼

Clinical trials demonstrate superior symptom control compared to intranasal steroid alone.

Provides faster onset of action due to antihistamine component.

Effective for moderate to severe allergic rhinitis.

Improves nasal airflow and quality of life scores.

Well tolerated for long-term seasonal use.

Patient Counseling Points ▼

Use regularly for best effect.

Avoid spraying directly onto nasal septum.

Mild bitter taste may occur temporarily.
