Salbutamol Tablets 4mg

Indications and Uses of Salbutamol

Salbutamol is indicated for respiratory conditions, leveraging its bronchodilatory effects to alleviate airway obstruction:

• Asthma: Treats acute asthma attacks and prevents symptoms triggered by allergens, exercise, or cold air, improving lung function, per Global Initiative for Asthma (GINA) guidelines.
• Chronic Obstructive Pulmonary Disease (COPD): Relieves bronchospasm in COPD patients, reducing breathlessness, used as a rescue therapy, supported by GOLD (Global Initiative for Chronic Obstructive Lung Disease) recommendations.
• Exercise-Induced Bronchospasm (EIB): Prevents EIB in athletes and active individuals, administered 15–30 minutes pre-exercise, with evidence from sports medicine studies.
• Bronchiolitis: Used off-label in infants with viral bronchiolitis to reduce wheezing, improving oxygenation, with pediatric pulmonology data.
• Cystic Fibrosis: Investigated off-label to manage airway obstruction in cystic fibrosis patients, enhancing mucus clearance, supported by cystic fibrosis research.
• Acute Hyperkalemia: Employed off-label to shift potassium into cells in emergency settings, stabilizing cardiac function, per nephrology protocols.
• Preterm Labor: Used off-label as a tocolytic to delay preterm delivery by relaxing uterine muscles, with obstetric evidence, though alternatives are preferred.
• Anaphylaxis Adjunct: Explored off-label as an adjunct in anaphylaxis to relieve bronchospasm, improving respiratory status, noted in allergy and emergency medicine studies.
• Post-Extubation Stridor: Administered off-label post-extubation to reduce laryngeal edema and stridor in ICU patients, with critical care data.

Dosage of Salbutamol

Dosage for Adults

• Oral (Maintenance):2–4 mg 3–4 times daily, maximum 32 mg/day.

Dosage for Children

• Oral (Maintenance, 2–11 years):0.1–0.2 mg/kg 3 times daily, maximum 24 mg/day.

Dosage for Pregnant Women

• Pregnancy Category C: Use only if benefits outweigh risks (e.g., severe asthma). Consult an obstetrician, with fetal monitoring.

Dosage Adjustments

• • • • Renal Impairment: No adjustment needed; monitor in severe cases (CrCl <30 mL/min).
      • Hepatic Impairment: No adjustment needed; monitor for systemic effects.
      • Elderly: Start with lower doses (e.g., 1 puff or 2 mg orally); increase cautiously.
      • Concomitant Medications: Reduce dose if combined with beta-blockers, which may antagonize effects.
