Pharmaceutical Form

Proventil has the following pharmaceutical forms:

  • metered aerosol for inhalation of 100 mg/dose (released in aluminum container under pressure, each inhaler contains 200 doses; when sprayed onto a glass surface leaves white spot);
  • metered powder for inhalation of 200 or 400 mcg/dose;
  • film coated pills of 2 and 4 mg.

Produced under other brand names salbutamol drugs can also be released as:

  • retard pills;
  • solution for inhalation;
  • solution for injections;
  • syrup;
  • concentrate for infusion solution;
  • capsules, filled with powder for inhalation.

Pharmacological Effect

Proventil (Salbutamol) is a bronchodilatory agent, selective β2-agonist (selective β2-adrenergic receptors antagonist). Pharmacological action of the drug: bronchodilator and tocolytic.

Pharmacodynamics and Pharmacokinetics

proventilWhen used in therapeutic doses it has a pronounced bronchodilator effect, prevents and relieves bronchspasm-inducing syndrome, increases vital lung capacity, inhibits histamine release into extracellular space, chemotactic factors, slowly reacting substance and a number of other highly active substances.

On salbutamol background slight positive ino- and chronotropic effects on heart muscle are observed.

The drug expands heart coronary arteries, suppresses early and late bronchial reactivity, reduces respiratory tract resistance, as well as myometrium tone and contractile activity, improves bronchial ciliated epithelium function, stimulates sputum discharge and mucus production.

This means has almost no effect on β1-adrenergic receptors, does not cause reduction in blood pressure and, in comparison with other drugs having similar mechanism of action, has much less effect on heart.

Proventil also has metabolic effect: reduces potassium concentration in blood plasma, affects process of glycogen breakdown to glucose (glycogenolysis) and insulin secretion.

For some patients (especially patients with bronchial asthma) it is able to provide hyperglycemic and lipolytic effects, thereby increasing risk of lactacidemic coma.

After administration of inhaled drug forms, effect begins to develop after 5 minutes and reaches its maximum in 30 – 90 minutes (approximately 75% of maximal effect is reached within 5 minutes).

From 10 to 20% of the dose, received by patient, enters respiratory tract, the remaining 80 – 90% remain in the device and deposited in oropharynx and then swallowed. Remaining in the respiratory tract material is partially absorbed in lungs and, without biotransforming therein, gets into bloodstream. A part of the drug in digestive tract is absorbed and extensively metabolised during first pass through liver, forming form phenolic sulphate.

Both conjugate and unmodified substance are excreted primarily with urine.


Indications for Proventil use are:

  • asthma bronchospasm in all forms (the means can be used for bronchospastic syndrome relief and prevention);
  • pulmonary emphysema;
  • chronic bronchitis;
  • asthmatic bronchitis;
  • uncomplicated premature labor.

Proventil is also used in pediatrics to treat bronchial obstruction.


  • hypersensitivity to drug components;
  • cardiac arrhythmia (for example, polymorphic ventricular premature beats or paroxysmal tachycardia);
  • cardiac abnormalities;
  • myocarditis;
  • tachyarrhythmia;
  • aortic stenosis;
  • ischemic heart disease;
  • thyrotoxicosis;
  • decompensated diabetes;
  • epileptic seizures;
  • glaucoma;
  • pyloroduodenal narrowing;
  • hepatic or renal function insufficiency;
  • pregnancy.

The drug is not indicated in combination with non-selective β-blockers, as well as for treating children up to 2 years old.

Caution must be taken at:

  • hyperthyroidism;
  • pheochromocytoma;
  • severe chronic cardiac insufficiency;
  • arterial hypertension.

Intravenously Proventil is contraindicated at:

  • intrauterine fetal death;
  • maternal passages infections;
  • hemorrhages associated with placental presentation;
  • premature placental abruption;
  • threatening miscarriage in 1 or 2 trimesters of pregnancy;
  • late toxicosis (toxicosis during 3 trimester of pregnancy).


Pregnancy and Lactation Period

Proventil is contraindicated during pregnancy. During lactation period the drug can be appointed if expected benefit to the mother outweighs possible risks to the child. This is due to its ability to penetrate into breast milk.

Side Effects

Proventil, released in aerosol form, when administered in therapeutic doses does not cause side effects.

If you exceed one-time or daily dose of salbutamol, as well as at patients with hypersensitivity to β2-adrenergic receptors stimulants, the most significant side effects are tremors of fingers or hands, inner trembling, increased tension.

In case of significant excess of therapeutic doses or hypersensitivity, patient may experience transient peripheral blood vessels expansion, dizziness, headaches, moderately severe tachycardia, nausea, muscle cramps, vomiting.

Very rare there angioneurotic edema, manifesting as skin rash, allergic reactions, urticaria fever, collapse, hypotension, bronchospasm.

Instructions for Use

At inhalation administration dosage depends on prescribed pharmaceutical form. In accordance with instructions for use, Proventil Inhaler is indicated for bronchospastic syndrome or asthma attack relief. Adults are usually recommended 0,1 – 0,2 mg, children – 0,1 mg.


Frequency of use depends on particular clinical situation and indications.

In order to prevent exercise-induced asthma attacks, before exercise children should administer dosage of 0,1 mg, for – 0,2 mg. Maximal daily dose – 0,8 mg (equivalent to 8 inhalations).

  • acidosis;
  • muscle tremor;
  • hypokalemia;
  • hypoxemia;
  • headaches;
  • malaise;
  • hypoglycemia, followed by hyperglycemia.

Treatment involves drug withdrawal, using cardioselective β-blockers and symptomatic therapy.

If there is suspicion of salbutamol overdose, it is necessary to keep serum potassium concentration level under constant control.

Drug Interactions

inhalerWhen Proventil is used in combination with non-cardioselective β-blockers, there is possible mutual therapeutic effects inhibition. In combination with theophylline the drug may increase arrhythmia and tachycardia risks (particularly supraventricular extrasystole).

In combination with diuretics, glucocorticosteroid drugs and xanthine derivatives, risk of hypokalemia increases.

Special Instructions

Increasing dosage or multiplicity of applications should be carried out under medical supervision. Reduction of intervals is allowed only in extreme cases, besides it must be strictly justified.

On the background of drug application there is a risk of hypokalemia, so patients with severe asthma are recommended to constantly monitor serum potassium concentration indicators. Risk of hypokalemia is increased at hypoxia.

World Anti-Doping Agency (WADA) prohibits Proventil (Salbutamol) in sport, because this drug has ability to artificially enhance endurance and physical activity during sports competitions.

Pills are usually recommended when it is impossible to use inhalers (e. g., infants), as this pharmaceutical form excess dosage may provoke cardiokinetic effect.

Reviews about Proventil
