Bena ExpectorantBena expectorant

Clears chesty Cough

 

Composition

Each 5 ml contains

Diphenhydramine Hydrochloride ............. 14 mg

Ammonium Chloride ............................... 135 mg

Sodium Citrate ........................................ 57.5 mg

Sodium Benzoate as preservative ............. 7.50 mg

Pharmacology
Diphenhydramine Hydrochloride, Ammonium Chloride and Sodium Citrate are readily and effectively absorbed from the gastrointestinal tract.

Diphenhydramine Hydrochloride is extensively metabolished in the liver and excreted mainly as metabolites is the urine.

After absorption, the ammonium ion from ammonium chloride is converted into urea in the liver, and the anion thus liberated into the blood stream and extracellular fluid causes a metabolic acidosis and decreases the pH of the urine; this may be followed by a transient diuresis. However, the acidifying effect occurs only with large does of ammonium chloride, in excess of about 2 g. Hence this effect will not be apparent with the small amount present in the expectorant. Sodium citrate is metabolized after absorption, and is partly excreted as carbon dioxide.

Indications
Bena is indicated for the relief of chest congestion and coughs with thick phlegm. It clears nasal passages, liquefies and loosens stubborn phlegm and soothes tiresome coughing.

Dosage and Administration

Unless otherwise prescribed by the physician:

 

Adult and children over 12 years:

5 to 10 ml every 4 to 6 hours

(not to exceed 60 ml in 24 hours);

 

Children 6 to 12 years:

2.5 to 5 ml every 4 to 6 hours (not to exceed 30 ml in 24 hours);

 

Children 2 to 5 years:

2.5 ml every 4 to 6 hours (not to exceed 20 ml in 24 hours).

 

Children below 2 years

as prescribed by the physician.

Side Effects
Antihistaminic side effects include sedation, dizziness, tinnitus, lassitude, incoordination, fatigue, blurred vision, diplopia, euphoria, nervousness, insomnia and tremors. Incidences of gastrointestinal side effects are low.

Large doses of ammonium chloride may cause nausea, thirst, headache and progressive drowsiness leading to profound acidosis and hypokalaemia. Excessive sodium salt may cause hypernatraemia. These effects are unlikely to occur with therapeutic dose of the preparation due to its low content of ammonium chloride and sodium salts.

Contraindications

In patients with known hypersensitivity to antihistamines.

Precautions
This medicine may cause drowsiness. If affected do not drive motor vehicles or operate machinery. Avoid taking alcoholic drinks or other drugs that may produce drowsiness.

Bena should be used with caution in patients with hepatic or renal diseases. Safety of this preparation in pregnancy has not been established and should be carefully assessed before use.

Symptoms and treatment of overdosage
Antihistamine overdosage may produce a mixture of excitatory and depressive effects on the central nervous system. Marked cerebral irritation, resulting in jerking of muscles and possible convulsions, may be followed by stupor.

There is no specific antidote for antihistamine poisoning. Symptomatic and supportive treatment may be employed. In severe overdosage he stomach should be emptied by aspiration and lavage Convulsions may be controlled with diazepam given intravenously.
