Mechanism of Action

Alverine Citrate works by relaxing the smooth muscles of the gastrointestinal tract. It acts on the smooth muscle cells by inhibiting the calcium influx necessary for muscle contraction. This reduces the spasms and pain associated with conditions like IBS.

How Long Does It Take to Work?

The onset of action for Alverine Citrate is typically within 30 to 60 minutes after oral administration. Symptom relief, including reduction in abdominal pain and discomfort, may be observed within this time frame. Full therapeutic effects are usually experienced after several days of consistent use.

Absorption

Alverine Citrate is well absorbed from the gastrointestinal tract after oral administration. The drug reaches peak plasma concentrations approximately 1 to 2 hours after ingestion. Food does not significantly affect the absorption of Alverine Citrate .

Route of Elimination

Alverine Citrate is metabolized in the liver, and its metabolites are excreted primarily in the urine. A small amount of the drug may be excreted in the feces. The rate of elimination can be influenced by liver function and renal health.

Dosage

Adult: Orally: 60-120 mg 1-3 times daily.

The recommended dosage of Alverine Citrate is:

Adults: 60 mg to 120 mg, taken 3 times daily before meals. The dosage may be adjusted based on patient response and tolerance.
Children: Safety and efficacy in children have not been established; therefore, use in pediatric patients is not generally recommended.

Administration

Alverine Citrate should be taken orally with a glass of water. It is recommended to take the medication before meals to maximize its efficacy in reducing gastrointestinal symptoms. Consistent use as prescribed by a healthcare provider is important for achieving optimal results.

Side Effects

Common side effects of Alverine Citrate include:

Abdominal discomfort
Diarrhea
Headache
Nausea

Serious side effects may include:

Allergic reactions (e.g., rash, itching, swelling)
Severe abdominal pain
Persistent or worsening gastrointestinal symptoms

Toxicity

In cases of overdose or excessive use of Alverine Citrate , symptoms may include severe gastrointestinal discomfort, nausea, and vomiting. Management involves discontinuing the medication and providing symptomatic and supportive care. Gastric lavage and activated charcoal may be considered in severe cases.

Precautions

Precautions should be taken in patients with:

Severe liver or renal impairment
History of gastrointestinal disorders
Known hypersensitivity to Alverine Citrate or any of its components

Regular monitoring is advised to ensure the medication is well-tolerated and effective.

Interaction

Alverine Citrate may interact with:

Other antispasmodics: Concurrent use may enhance antispasmodic effects, potentially leading to increased side effects.
Antacids: May affect the absorption of Alverine Citrate , although this interaction is generally minimal.

Disease Interaction

Use Alverine Citrate with caution in patients with:

Gastrointestinal obstruction or severe constipation
Active gastrointestinal bleeding
Renal or hepatic impairment

Drug Interaction

Drug interactions with Alverine Citrate are relatively few. However, potential interactions include:

Anticholinergic drugs: May have additive antispasmodic effects.
Other medications affecting gastrointestinal motility: May alter the effectiveness of Alverine Citrate .

Food Interactions

There are no significant food interactions with Alverine Citrate . It is generally recommended to take the medication before meals, but food intake does not substantially alter its efficacy.

Pregnancy Use

Alverine Citrate is classified as pregnancy category B. It should be used during pregnancy only if clearly needed. The drug's safety during pregnancy has not been fully established, so it should be used under medical supervision with a careful risk-benefit assessment.

Lactation Use

Alverine Citrate is excreted in breast milk in small amounts. While it is generally considered safe for use during lactation, caution is advised. Monitor for any potential adverse effects in the nursing infant, and consult a healthcare provider if concerns arise.

Acute Overdose

Acute overdose of Alverine Citrate may result in severe gastrointestinal symptoms, including pain, nausea, and vomiting. Management involves discontinuing the medication and providing supportive care. In severe cases, medical intervention may be required.

Contraindication

Alverine Citrate is contraindicated in patients with:

Hypersensitivity to Alverine Citrate or any of its components
Severe gastrointestinal obstruction or conditions that could be exacerbated by smooth muscle relaxation
Severe liver or renal impairment where drug metabolism or excretion could be significantly impaired

Use Direction

Alverine Citrate should be used according to the prescribed dosage and administration instructions. Take the medication before meals, and follow the healthcare provider’s recommendations for duration and frequency of use. Adhere to the dosage instructions to avoid potential side effects and ensure effectiveness.

Storage Conditions

Store Alverine Citrate at room temperature, between 20°C and 25°C (68°F and 77°F). Protect from light and moisture. Keep the medication tightly closed and out of reach of children.

Volume of Distribution

The volume of distribution of Alverine Citrate is not well-documented but is generally low due to its limited systemic absorption. Most of the drug remains within the gastrointestinal tract where it exerts its therapeutic effects.

Half Life

The plasma half-life of Alverine Citrate is approximately 2 to 4 hours. The drug's effects on smooth muscle relaxation last longer than its presence in the plasma due to its local action and metabolism.

Clearance

Alverine Citrate is primarily metabolized by the liver and cleared through the urine. The clearance rate may be affected by liver or renal impairment. Regular monitoring may be needed for patients with significant hepatic or renal conditions.
