Mechanism of Action

Antrenyl Tablet 5 mg functions as a competitive antagonist of acetylcholine at muscarinic receptors. By blocking these receptors, it inhibits the parasympathetic nervous system’s stimulation of gastrointestinal smooth muscle and glandular secretions, leading to reduced gastric acid secretion and decreased bowel motility.

How Long Does It Take to Work?

The onset of action for Antrenyl Tablet 5 mg is typically within 30 to 60 minutes after oral administration. The duration of its effects can last several hours, depending on the dose and individual response.

Absorption

Antrenyl Tablet 5 mg is well absorbed from the gastrointestinal tract following oral administration. Peak plasma concentrations are usually reached within 1 to 2 hours. The drug’s bioavailability may be affected by food intake and gastrointestinal conditions.

Route of Elimination

The drug is metabolized primarily in the liver and excreted in the urine. A small portion of the drug may be excreted unchanged, while the majority is eliminated as metabolites.

Dosage

Average adult dosage is 10 mg (2 tablets) 4 times daily for several days. Dosage may be reduced depending on patient's response or as directed by the physician.

Adults:

• The typical starting dose is 5 mg taken 3 to 4 times a day before meals. The dose can be adjusted based on the patient’s response and tolerance.
• For severe cases, the dose may be increased to 10 mg taken 3 to 4 times a day, but this should be done under strict medical supervision.

Geriatric Use:

• Older adults may require a lower starting dose due to increased sensitivity to anticholinergic effects. It is advisable to start with the lowest effective dose and adjust as needed.

Dosage Adjustments:

• Dosage adjustments may be necessary in patients with liver impairment or those on concurrent medications that affect hepatic function.
