Palmolev

Uses

Palmolev tablet is used for the treatment or prevention of bronchospasm in adults, adolescents, and children 6 years of age and older with reversible obstructive airway disease.

Palmolev Nebuliser Solution or Inhaler is used for the treatment or prevention of bronchospasm in adults, adolescents, and children with reversible obstructive airway disease.

Palmolev is also used to associated treatment for these conditions: Bronchospasm

How Palmolev works

β2 adrenergic receptors on airway smooth muscle are Gs coupled and their activation by levosalbutamol leads to activation of adenylate cyclase and to an increase in the intracellular concentration of 3',5'-cyclic adenosine monophosphate (cyclic AMP). Increased cyclic AMP activates protein kinase A which itself inhibits the phosphorylation of myosin produces lower intracellular ionic calcium concentrations, inducing muscle relaxation. Increased cyclic AMP concentrations are also associated with the inhibition of the release of mediators from mast cells in the airways, potentially contributing to its benefit in asthma attacks.

Dosage

Palmolev dosage

• Adults and children above 12 years: 1-2 mg three times daily.
• Children (6 -11 years): 1 mg three times daily.

Palmolev Inhaler-

You should take your Palmolev Inhaler as needed for an asthma attack at any time of day, with or without food, by taking 1-2 puffs up to 4 times daily and no more than 8 puffs in 24 hours. If you are using your Palmolev Inhaler more than 3-4 times a week this may indicate that your asthma is not well controlled and you may need to review your medication. You can also use your Palmolev Inhaler to prevent allergy or exercise induced asthma by taking 2 puffs 15 minutes before exercise or exposure to a known allergen.

Side Effects

Potentially serious side effects like hypokalamia may result from ß-2 agonist therapy. This effect may be potentiated by hypoxia. The other likely side effects are gastrointestinal disturbances such as nausea, vomiting, burning substernal or epigastric pain and diarrhoea. In some cases nervousness, headache, dizziness, fatigue and sleeplessness may occur.

Precaution

Particular caution is advised in acute severe asthma as this effect may be potentiated by hypoxia and by concomitant treatment with xanthine derivatives, steroids and diuretics. Serum potassium levels should be monitored in such situations. Oral Palmolev should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias or hypertension. Palmolev can be used with caution after myocardial infarction.

Palmolev Hydrochloride, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, hypertension, and cardiac arrhythmias; in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus; and in patients who are unusually responsive to sympathomimetic amines. Palmolev Nebuliser Solution or Inhaler must not be injected.

Interaction

Other short-acting sympathomimetic bronchodilators or epinephrine should be used with caution with Palmolev. If additional adrenergic drugs are to be administered by any route, they should be used with caution to avoid deleterious cardiovascular effects.

Food Interaction

Elimination Route

Inhalation delivers the medication directly into the airways and lungs, thereby minimizing side effects because of reduced systemic absorption of the inhaled medications.

Half Life

3.3 - 4 hours

Elimination Route

excreted into the urine.

Pregnancy & Breastfeeding use

Use in pregnancy: Use of oral Palmolev in pregnant women should be considered only if the expected benefit to the mother is greater than any possible risk to the foetus or the infant.

Use in lactation: It is not known whether Palmolev is excreted in human milk. Caution should be exercised when oral Palmolev is administered to a nursing woman.

Pregnancy: There are no adequate and well-controlled studies of Palmolev Nebuliser Solution in pregnant women. Palmolev Solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Lactation: It is not known whether Palmolev is excreted in human milk. Caution should be exercised when Palmolev Nebuliser Solution is administered to a nursing woman.

Contraindication

Palmolev Nebuliser Solution is contraindicated in patients with a history of hypersensitivity to Palmolev Hydrochloride or racemic salbutamol.

Acute Overdose

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the symptoms listed under side effects e.g., tachycardia, nervousness, headache, tremor, nausea, dizziness, fatigue and sleeplessness. Hypokalaemia also may occur. Treatment consists of discontinuation of oral Palmolev together with appropriate symptomatic therapy. In the event of serious poisoning, the stomach should be emptied and, if necessary, a beta-blocker administered with caution in patients with a history of bronchospasm.

Storage Condition

Store at cool and dry place. Protected from light and moisture. Keep out of the reach of children.
