How Abexol Syrup (200 mg+15 mg+15 mg)/5 ml works

Dextromethorphan is an agonist of NMDA and sigma-1 receptors. It is also an antagonist of α3/β4 nicotinic receptors.[A10589] However, the mechanism by which dextromethorphan's receptor agonism and antagonism translates to a clinical effect is not well understood.

Although the exact mechanism of action of guaifenesin may not yet be formally or totally elucidated, it is believed that expectorants like guaifenesin function by increasing mucus secretion . Moreover, it is also further proposed that such expectorants may also act as an irritant to gastric vagal receptors, and recruit efferent parasympathetic reflexes that can elicit glandular exocytosis that is comprised of a less viscous mucus mixture . Subsequently, these actions may provoke coughing that can ultimately flush difficult to access, congealed mucopurulent material from obstructed small airways to facilitate a temporary improvement for the individual .

Consequently, while it is generally proposed that guaifenesin functions as an expectorant by helping to loosen phlegm (mucus) and thin bronchial secretions to rid the bronchial passageways of bothersome mucus and make coughs more productive, there has also been research to suggest that guaifenesin possesses and is capable of demonstrating anticonvulsant and muscle relaxant effects to some degree possibly by acting as an NMDA receptor antagonist .

Dosage

Abexol Syrup (200 mg+15 mg+15 mg)/5 ml dosage

Adult Use Only (12 years and over): 2 teaspoonful syrup (10 ml) every 6 hours. Maximum 8 teaspoonful syrup (40 ml)/day.

Side Effects

Common side effects may include:

• Dizziness, drowsiness;
• Gastrointestinal disturbance
• Feeling nervous, restless, anxious, or irritable

Toxicity

A dextromethorphan overdose may present as nausea, vomiting, stupor, coma, respiratory depression, seizures, tachycardia, hyperexcitability, toxic psychosis, ataxia, nystagmus, dystonia, blurred vision, changes in muscle reflexes, and serotonin syndrome. Overdose should be managed through symptomatic and supportive measures.

The most prevalent signs and symptoms associated with an overdose of guaifenesin have been nausea and vomiting .

Although adequate and well-controlled studies in pregnant women have not been performed, the Collaborative Perinatal Project monitored 197 mother-child pairs exposed to guaifenesin during the first trimester . An increased occurrence of inguinal hernias was found in the neonates . However, congenital defects were not strongly associated with guaifenesin use during pregnancy in 2 large groups of mother-child pairs .

Moreover, guaifenesin is excreted in breast milk in small quantities . Subsequently, caution should be exercised by balancing the potential benefit of treatment against any possible risks .

Additionally, an LD₅₀ value of 1510 mg/kg (rat, oral) has been reported for guaifenesin .

Precaution

Talk to a doctor before using this product if you have asthma, chronic lung disease or shortness of breath, persistent/chronic cough, or taking a drug for depression, including monoamine oxidase (MAO) inhibitor drugs.

Interaction

Possible reactions systemically may occur with acetaminophen / hydrocodone, diphenhydramine, escitalopram, acetaminophen / codeine, alprazolam and ondansetron.

Volume of Distribution

The volume of distribution of dextromethorphan is 5-6.7L/kg.

The geometric mean apparent volume of distribution of guaifenesin determined in healthy adult subjects is 116L (CV=45.7%) .

Elimination Route

A 30mg oral dose of dextromethorphan reaches a C_max of 2.9 ng/mL, with a T_max of 2.86 h, and an AUC of 17.8 ng*h/mL.

Studies have shown that guaifenesin is well absorbed from and along the gastrointestinal tract after oral administration .

Half Life

Dextromethorphan has a half life of 3-30 hours.

The half-life in plasma observed for guaifenesin is approximately one hour .

Clearance

The mean clearance recorded for guaifenesin is about 94.8 L/hr (CV=51.4%) .

Elimination Route

After administration, guaifenesin is metabolized and then largely excreted in the urine .

Pregnancy & Breastfeeding use

Dextromethorphan Hydrobromide-guaifenesin have been assigned to pregnancy category C by the FDA. There are no controlled data on this combination product in human pregnancy.

Dextromethorphan Hydrobromide-guaifenesin is only recommended for use during pregnancy when benefit outweighs risk.

There are no data on the excretion of dextromethorphan-guaifenesin into human milk. In nursing infants, a decision should be made to discontinue. There are no human studies on the use of menthol during pregnancy; thus, its risk is undetermined.

Contraindication

If you are now taking a prescription monoamine oxidase inhibitor (MAOI) (certain drugs for depression, psychiatric or emotional conditions, or Parkinson’s disease), or for two weeks after stopping the MAOI drug. If you do not know if your prescription drug contains an MAOI, ask a doctor or pharmacist before taking this product.

Acute Overdose

Overdosage with guaifenesin is unlikely to produce toxic effects since its toxicity is low. In severe cases of overdosage, treatment should be aimed at reducing further absorption of the drug. Gastric emptying (emesis and/or gastric lavage) is recommended as soon as possible after ingestion. Overdosage with Dextromethorphan Hydrobromide may produce excitement and mental confusion. Very high doses may produce respiratory depression. One case of toxic psychosis (hyper-activity, marked visual and auditory hallucinations) after ingestion of a single 300 mg dose of Dextromethorphan Hydrobromide has been reported. Menthol can be harmful in large amounts. Symptoms may include abdominal pain, diarrhea, nausea and vomiting, dizziness, rapid breathing etc.

Storage Condition

Keep out of the reach of children. Keep in a cool & dry place. Protect from light.
