BRONCHO SALINE
Clinical safety rating: caution
Comprehensive clinical and safety monograph for BRONCHO SALINE (BRONCHO SALINE).
Sodium chloride acts as a hyperosmolar agent that hydrates mucus by osmotic effect, reducing mucus viscosity and facilitating clearance.
| Metabolism | Not metabolized; absorbed systemically as sodium and chloride ions. |
| Excretion | Renal elimination of sodium and chloride ions; no significant biliary or fecal excretion. |
| Half-life | Not applicable; sodium chloride is physiologically regulated and not eliminated via first-order kinetics. |
| Protein binding | Negligible; sodium and chloride ions do not bind significantly to plasma proteins. |
| Volume of Distribution | Approximately 0.5 L/kg; distributes throughout extracellular fluid. |
| Bioavailability | 100% via inhalation (direct airway delivery); oral bioavailability not relevant. |
| Onset of Action | Immediate upon inhalation; mucolysis occurs within minutes. |
| Duration of Action | 30-60 minutes post-inhalation; effects on mucus clearance persist for duration of treatment. |
Inhalation: 2.5-5 mL via nebulizer 3-4 times daily as needed.
| Dosage form | AEROSOL, METERED |
| Renal impairment | No adjustment required; not systemically absorbed. |
| Liver impairment | No adjustment required; not metabolized by liver. |
| Pediatric use | Inhalation: 1-2.5 mL via nebulizer 3-4 times daily as needed. |
| Geriatric use | Same as adult dosing; no specific adjustment needed. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note
Comprehensive clinical and safety monograph for BRONCHO SALINE (BRONCHO SALINE).
| Breastfeeding | No systemic absorption occurs with inhaled saline. Sodium chloride is a normal component of breast milk; no risk to nursing infant. M/P ratio not applicable as drug is not quantified in plasma. |
| Teratogenic Risk | Broncho Saline (0.9% sodium chloride) is not absorbed systemically via inhalation; therefore, no direct fetal exposure occurs. No teratogenic risk is expected in any trimester. |
| Fetal Monitoring |
■ FDA Black Box Warning
None
| Serious Effects |
["Hypersensitivity to sodium chloride","Severe electrolyte imbalance (hypernatremia, hyperchloremia)","Pulmonary edema"]
| Precautions | ["Use with caution in patients with congestive heart failure, hypertension, or renal impairment due to sodium load","Inhaled saline may cause bronchospasm in asthmatics","Sterile solution required to avoid infection"] |
| Food/Dietary | No known food interactions. |
| Clinical Pearls | Broncho Saline (sterile 0.9% sodium chloride solution) is used for inhalation to hydrate airways and thin mucus. Ensure the solution is at room temperature to prevent bronchospasm. Do not use if discolored or cloudy. Advise patients to rinse mouth after use to prevent irritation. |
Loading safety data…
| None required. Standard monitoring for underlying respiratory condition may be warranted but not specific to saline. |
| Fertility Effects | No known effects on fertility. Inhaled saline does not undergo systemic absorption or interact with reproductive hormones. |
| Patient Advice | Use only as directed by your healthcare provider. · Do not swallow the solution; it is for inhalation only. · Store at room temperature and protect from freezing. · Discard any unused solution after 24 hours if mixed with other medications. · Contact your doctor if you experience difficulty breathing, chest tightness, or wheezing after use. |
