How Indx Expt works

Ambroxol is a mucolytic agent. Excessive Nitric oxide (NO) is associated with inflammatory and some other disturbances of airways function. NO enhances the activation of soluble guanylate cyclase and cGMP accumulation. Ambroxol has been shown to inhibit the NO-dependent activation of soluble guanylate cyclase. It is also possible that the inhibition of NO-dependent activation of soluble guanylate cyclase can suppress the excessive mucus secretion, therefore it lowers the phlegm viscosity and improves the mucociliary transport of bronchial secretions.

Terbutaline is a selective beta-2 adrenergic receptor agonist. Agonism of these receptors in bronchioles activates adenylyl cyclase, increasing intracellular cyclic adenosine monophosphate (cAMP). Increased cAMP decreases intracellular calcium, activating protein kinase A, inactivating myosin light-chain kinase, activating myosin light-chain phosphatase, and finally relaxing smooth muscle in the bronchiole.

Specific application features: Ambroxol may be prescribed to patients suffering from diabetes mellitus.

The recommended adult dose for treating asthma, emphysema or bronchitis is 2.5-5 mg 3 times daily approximately 6 hours apart while awake. The maximum dosage is 15 mg/day. Shake the inhaler several times and uncap the mouthpiece. Breathe out fully. For best results, hold the inhaler 1 to 2 inches in front of your open mouth or attach a spacer to the inhaler and place the spacer in your mouth, above your tongue and past your teeth. Take a deep, slow breath as you push down on the canister. Hold your breath for 10 seconds, then exhale slowly. Use nebulizer machine for better response.

Side Effects

Gastrointestinal side-effects like epigastric pain, gastric fullness may occur occasionally. Rarely allergic responses such as eruption, urticaria or angioneurotic edema may occur.

Dry mouth, irritated throat, nausea, dizziness, headache, heartburn, loss of appetite, altered taste sensation, restlessness, anxiety, nervousness, trembling, and sweating may occur but should subside as your body adjusts to the medication.

Toxicity

Patients experiencing an overdose may present with abdominal pain, agitation, palpitations, seizures, angina, hypertension, hypotension, tachycardia, arrhythmias, nervousness, headache, tremor, dry mouth, nausea, dizziness, fatigue, malaise, insomnia. Discontinue treatment with terbutaline and initiate symptomatic and supportive therapy.

Precaution

Ambroxol should be given cautiously to patients with gastric and duodenal ulceration or convulsive disorders. Patients with hepatic and renal insufficiency should take it with caution.

Before you use this drug, tell your doctor if you have: any allergies, heart disease, high blood pressure, an overactive thyroid gland, seizures, diabetes. Tell your doctor if you ever had a bad reaction to albuterol, bitolterol, ephedrine, epinephrine, isoetharine, isoproterenol, metaproterenol, pseudoephedrine, or pirbuterol or other similar agents. Tell your doctor if you are pregnant before using this medication. Terbutaline is excreted into breast milk. Consult with your doctor before breast-feeding. Terbutaline is not recommended for children under the age of 6. Caution is advised in the elderly.

Interaction

Ambroxol has no interaction with cardioactive glycosides, corticosteroids, bronchodilators, diuretics and antibiotics (normally used in the treatment of bronchopulmonary affections). But Ambroxol should not be taken simultaneously with antitussives (e.g. Codeine) because mucus, which has been liquefied by Ambroxol, might not be expectorated.

Tell your doctor of all nonprescription and prescription medications you take, including: beta-blockers (e.g., propranolol, timolol), all asthma drugs, antidepressants, MAO inhibitors (e.g., furazolidone, linezolid, phenelzine, selegiline, tranylcypromine), diuretics (e.g., hydrochlorothiazide). Many nonprescription medications contain pseudoephedrine or ephedrine, so check the labels carefully. Do not take any of these medications without consulting your doctor. Do not start or stop any medicine without doctor or pharmacist approval.

Volume of Distribution

Terbutaline has a mean volume of distribution of 1.6 L/kg.

Elimination Route

Rapid and almost complete.

A 0.5 mg subcutaneous dose of terbutaline reaches a mean C_max of 9.6 ± ng/mL, with a median T_max of 0.5 hours, and a mean AUC of 29.4 ± 14.2 h*ng/mL. A 5 mg oral terbutaline tablet reaches a mean C_max of 8.3 ± 3.9 ng/mL with a median T_max of 2 hours, and a mean AUC of 54.6 ± 26.8 h*ng/mL. A 5 mg oral terbutaline solution reaches a mean C_max of 8.6 ± 3.6 ng/mL, with a median T_max of 1.5 hours, and a mean AUC of 53.1 ± 23.5 h*ng/mL.

Oral terbutaline has an oral bioavailability of 14-15%.

Half Life

7-12 hours

An oral dose of terbutaline has an elimination half life of 3.4 hours, while a subcutaneous dose has an elimination half life of 2.9 hours.

Clearance

The average clearance of terbutaline is 3.0 mL/min/kg.

Elimination Route

An oral dose of terbutaline is 40% eliminated in the urine after 72 hours. The major metabolite in the urine was the sulphate conjugated form of terbutaline. Parenteral doses of terbutaline are 90% eliminated in the urine, with approximately 2/3 as the unchanged parent drug. Less than 1% of a dose of terbutaline is eliminated in the feces.

Pregnancy & Breastfeeding use

Pregnancy: Teratogenic and fetal toxicity studies have shown no harmful effect of Ambroxol. However, it is advised not to use during pregnancy, especially in the 1st trimester.

Lactation: Safety during lactation has not been established.

Although no teratogenic effects have been observed in animals or in patients, Terbutaline should only be administered with caution during the first trimester of pregnancy. Terbutaline is secreted via breast milk, but effect on the infant is unlikely at therapeutic doses.

Contraindication

Contraindicated in known hypersensitivity to Ambroxol or Bromhexine.

Do not use Terbutaline if

• You are allergic to any ingredient in Terbutaline or to a sympathomimetic amine (eg, epinephrine, albuterol).
• You need to treat prolonged (more than 48 to 72 hours) premature labor.

Special Warning

Terbutaline is not approved for use by children younger than 6 years of age.

Storage Condition

Store at room temperature between 15 to 30° C. Keep away from moisture and sunlight. Do not puncture. Keep away from the reach of children.
