Ventolin Flashcards

Study Notes

Ventolin Overview

Generic names for Ventolin include Salbutamol and Albuterol Sulfate.
Classified as a bronchodilator and a beta2-selective adrenergic agonist (sympathomimetic).

Forms of Supply

Available as 2.5 mL nebule (1 mg/mL) and metered-dose inhaler (MDI) with 100 mcg/spray.
Combination therapy includes Combivent, which contains Ventolin (2.5 mg) and Atrovent (500 mcg).

Mechanism of Action

Selectively stimulates beta-adrenergic receptors in the lungs, uterus, and vascular smooth muscle.
Promotes bronchodilation by relaxing vascular smooth muscles, reducing airway resistance and bronchospasm.
Higher doses may lead to shifting of serum potassium (K+) into cells.

Indications for Use

Effective for bronchospasm in asthma, chronic bronchitis, and other chronic broncho-pulmonary disorders, as well as in anaphylaxis.
Treats hyperkalemia by promoting cellular uptake of potassium.

Dosage Information

Adult dose for bronchospasm: 5.0 mg via neb, repeat every 10 minutes as needed; or 10 puffs with a spacer every 5 minutes using MDI.
Adult dose for hyperkalemia: 10-20 mg nebulized over 10 minutes; if starting at 1 mg/mL, begin with 5 mg nebulized continuously until the total dose is reached.
Pediatric dose: 0.15 mg/kg diluted to 2.5 mL saline via nebulizer; specific dosing based on weight:
- <10 kg: 1.25 mg with NS to 2.5 mL
- 10-20 kg: 2.5 mg
- 20 kg: 2.5 - 5.0 mg
- MDI usage: minimum of 2 puffs, maximum of 10.

Contraindications

Avoid in cases of hypersensitivity to Ventolin or its components.
Not recommended for patients with tachydysrhythmias.

Precautions

Should not be used for cardiac asthma management.
Caution advised in individuals with cardiovascular disease, including cardiac dysrhythmias and hypertension.
Use with caution in patients with diabetes mellitus due to the risk of drug-induced hyperglycemia.
Hypokalemia presents a risk as Ventolin may further lower serum potassium levels, potentially leading to adverse cardiovascular events.
