Mebeverina Aristo (Mebeverine Hydrochloride)

Mebeverine Hydrochloride is employed as an antispasmodic for functional gastrointestinal disorders.

• Irritable bowel syndrome (IBS): reduces abdominal pain and cramping associated with bowel irregularities.
• Functional gastrointestinal disorders: alleviates spasmodic episodes and improves bowel habit regularity.
• Colicky abdominal pain: relaxes smooth muscle to lessen intensity and frequency of colicky episodes.

• Mebeverine Hydrochloride acts directly on gastrointestinal smooth muscle by inhibiting calcium influx through voltage‑dependent channels. This reduction in intracellular calcium diminishes muscle contractility, leading to relaxation of the intestinal wall without significant anticholinergic activity. The drug’s local action provides symptomatic relief of spasm‑related pain while preserving normal motility. It does not significantly affect the central nervous system and has a rapid onset after oral administration.

Mebeverine Hydrochloride may be associated with several adverse reactions, which are generally mild but can be serious in rare cases.

Common Side Effects

• Nausea: mild stomach upset occurring shortly after dosing.
• Dry mouth: reduced salivation leading to a feeling of thirst.
• Headache: transient head discomfort without neurological signs.
• Dizziness: light‑headed sensation, especially when standing quickly.

Serious or Rare Side Effects

• Allergic reactions: rash, itching, swelling, or anaphylaxis requiring immediate medical attention.
• Severe abdominal pain: persistent or worsening pain that does not improve with treatment.
• Hepatic enzyme elevation: abnormal liver function tests indicating possible liver involvement.

When using Mebeverine Hydrochloride, certain precautions should be observed to ensure safe and effective therapy.

• Hypersensitivity: discontinue if any allergic reaction such as rash or swelling occurs.
• Hepatic impairment: use with caution in patients with liver disease; monitor liver function.
• Renal impairment: dose adjustment may be needed for severe kidney dysfunction.
• Pregnancy and lactation: safety not established; prescribe only if potential benefit outweighs risk.
• Driving and machinery: avoid operating vehicles or heavy equipment if dizziness occurs.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Mebeverine Hydrochloride can interact with other medicines; awareness of these interactions helps avoid adverse outcomes.

Major Interactions (Avoid)

• Anticholinergic agents: combined use may intensify antispasmodic effects and cause excessive dryness.
• Other smooth‑muscle relaxants: additive relaxation may lead to gastrointestinal hypotonia.

Moderate Interactions (Monitor Closely)

• Antidepressants (SSRIs, TCAs): may alter gastrointestinal motility, requiring symptom monitoring.
• Antihistamines: can increase dry‑mouth sensation.
• Alcohol: may enhance dizziness and central nervous system effects.
• CYP450 inhibitors: potential to increase plasma levels of mebeverine, warranting dosage review.
