Chlorpheniramine is an alkylamine antihistamine. It is one of the most potent H1 blocking agents and is generally effective in relatively low doses. Chlorpheniramine is not so prone to produce drowsiness, readily absorbed from the gastro-intestinal tract, metabolised in the liver and excreted usually mainly as metabolised in the urine.
In allergic reactions an allergen interacts with and cross-links surface IgE antibodies on mast cells and basophils. Once the mast cell-antibody-antigen complex is formed, a complex series of events occurs that eventually leads to cell-degranulation and the release of histamine (and other chemical mediators) from the mast cell or basophil. Once released, histamine can react with local or widespread tissues through histamine receptors. Histamine, acting on H1-receptors, produces pruritis, vasodilatation, hypotension, flushing, headache, tachycardia, and bronchoconstriction. Histamine also increases vascular permeability and potentiates pain. Chlorpheniramine, is a histamine H1 antagonist (or more correctly, an inverse histamine agonist) of the alkylamine class. It competes with histamine for the normal H1-receptor sites on effector cells of the gastrointestinal tract, blood vessels and respiratory tract. It provides effective, temporary relief of sneezing, watery and itchy eyes, and runny nose due to hay fever and other upper respiratory allergies.
Terbutaline is a relatively selective β2-adrenergic bronchodilator that has little or no effect on alpha-adrenergic receptors. The drug has exerts a preferential effect on β2-adrenergic receptors but stimulates beta-adrenergic receptors less selectively than relatively selective β2-agonists. Terbutaline appears to have a greater stimulating effect on beta-receptors of the bronchial, vascular, and uterine smooth muscles (β2 receptors) than on the beta-receptors of the heart (β1 receptors). This drug relaxes smooth muscle and inhibits uterine contractions, but may also cause some cardiostimulatory effects and CNS stimulation.
The pharmacologic effects of terbutaline are at least in part attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3',5'- adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.
Terbutaline is a beta-2 adrenergic receptor agonist indicated to treat reversibly bronchospasm in asthmatic patients with bronchitis and emphysema. It has a short duration as the inhaled form is taken up to three times daily, and the therapeutic window is wide.

How Cadicoff Exl Expt works
Chlorpheniramine binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
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.
Dosage
Cadicoff Exl Expt dosage
Adults: 4 mg 3-4 times daily.
Children:
- Up to 1( one) year: 1 mg twice daily
- 1-5 years: 1 mg 3-4 times daily
- 6-12 years: 2 mg 3-4 times daily or as directed by the physician
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.

Volume of Distribution
Terbutaline has a mean volume of distribution of 1.6 L/kg.
Elimination Route
Well absorbed in the gastrointestinal tract.
A 0.5 mg subcutaneous dose of terbutaline reaches a mean Cmax of 9.6 ± ng/mL, with a median Tmax 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 Cmax of 8.3 ± 3.9 ng/mL with a median Tmax of 2 hours, and a mean AUC of 54.6 ± 26.8 h*ng/mL. A 5 mg oral terbutaline solution reaches a mean Cmax of 8.6 ± 3.6 ng/mL, with a median Tmax 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
21-27 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 Category B. Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).
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
There is no definite contraindication to therapy. It should be used with caution in epilepsy, prostatic hypertrophy, glaucoma and hepatic disease. The ability to drive or operate machinery may be impaired.
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.
