# Meftal spas
## Overview
Meftal spas is a brand name for a combination product containing mefenamic acid and dicyclomine. Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID). Dicyclomine is an anticholinergic antispasmodic.
## Primary Indications
Meftal spas is primarily indicated for the symptomatic relief of abdominal pain and cramps associated with gastrointestinal disorders.
## Adult Dosing
* **Meftal spas:** Typically 1 tablet three times daily. The maximum daily dose for mefenamic acid is generally 1500 mg. Dicyclomine dose should not exceed 40 mg daily.
* Specific dosing may vary based on the severity of symptoms and local prescribing guidelines.
## Pediatric Dosing
Dosing for pediatric patients is not well-established for this specific combination product. Mefenamic acid dosing in pediatrics is typically based on weight and indication, and dicyclomine is generally not recommended for infants and young children due to the risk of serious side effects. Consultation with a pediatrician is essential.
## Dose Adjustments
* **Renal Impairment:** Caution is advised. Mefenamic acid can worsen renal function. Dose reduction may be necessary, or alternative agents considered.
* **Hepatic Impairment:** Caution is advised. Mefenamic acid can cause liver enzyme elevations. Dose reduction may be necessary, or alternative agents considered.
* **Elderly:** Increased risk of adverse effects from NSAIDs (GI bleeding, renal, cardiovascular events). Use with caution and at the lowest effective dose.
## Contraindications
* Hypersensitivity to mefenamic acid, dicyclomine, or other NSAIDs.
* Active gastrointestinal bleeding or perforation.
* History of NSAID-induced GI ulceration or bleeding.
* Severe renal, hepatic, or cardiac impairment.
* Obstructive uropathy or gastrointestinal obstruction.
* Uncontrolled glaucoma.
* Myasthenia gravis.
* Infants < 6 months of age (for dicyclomine component).
## Adverse Effects
* **Mefenamic Acid:** Dyspepsia, nausea, vomiting, diarrhea, constipation, abdominal pain, peptic ulceration, GI bleeding, dizziness, headache, rash, renal impairment, hepatic enzyme elevations.
* **Dicyclomine:** Dry mouth, blurred vision, urinary retention, constipation, drowsiness, dizziness, confusion, tachycardia.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin):** Increased risk of bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Other NSAIDs and Aspirin:** Increased risk of GI adverse effects.
* **Diuretics and ACE Inhibitors:** Reduced antihypertensive effect and increased risk of renal impairment.
* **Anticholinergic Agents:** Additive anticholinergic effects with dicyclomine.
* **MAO Inhibitors:** May potentiate anticholinergic effects of dicyclomine.
## Monitoring
* Monitor for signs and symptoms of GI bleeding (e.g., melena, hematemesis).
* Assess renal and hepatic function periodically, especially with long-term use.
* Monitor for signs of cardiovascular events with NSAID use.
* Monitor for anticholinergic side effects with dicyclomine.
## Clinical Pearls
* Meftal spas should be used for short-term symptomatic relief.
* It is generally recommended to take with food or milk to minimize GI upset.
* Due to the anticholinergic component, caution is advised in patients with conditions that could be exacerbated by anticholinergics (e.g., heart failure, prostatic hypertrophy).
* This combination product should be used with caution in the elderly due to increased risk of NSAID-related adverse events.
