Cyclopam

# Cyclopam ## Overview - **Classification**: Antispasmodic (Dicyclomine) and Analgesic/Antipyretic (Paracetamol/Acetaminophen) combination. - **Mechanism**: Dicyclomine directly relaxes smooth muscle and blocks acetylcholine at muscarinic receptors. Paracetamol inhibits prostaglandin synthesis in the CNS. ## Primary Indications 1. **Abdominal Pain/Cramps**: Relief of spasms associated with intestinal colic, irritable bowel syndrome. 2. **Associated Pain/Fever**: Alleviation of mild to moderate pain and fever accompanying gastrointestinal distress. ## Adult Dosing ### Standard Dosing **Abdominal Pain/Spasms with Pain/Fever** - **Dose**: **Dicyclomine 20 mg + Paracetamol 500 mg** (typically one tablet) - **Frequency**: **Every 6-8 hours** as needed - **Route**: Oral - **Maximum**: Dicyclomine **80 mg/day**. Paracetamol **4000 mg/day** (from all sources). ### Dose Adjustments - **Renal Impairment**: - Dicyclomine: Use with caution. Reduced doses may be necessary. - Paracetamol: Extend dosing interval for CrCl < 30 mL/min (e.g., q8h-q12h). Avoid in severe impairment. - **Hepatic Impairment**: - Dicyclomine: Contraindicated in severe hepatic disease. Use with caution in moderate. - Paracetamol: Contraindicated in severe hepatic impairment. Use with caution, reduced dose/frequency in moderate impairment. - **Elderly Patients**: Increased susceptibility to anticholinergic effects (e.g., confusion, urinary retention). Start low, go slow. ## Pediatric Dosing (Cyclopam suspension typically contains Dicyclomine 10mg + Paracetamol 125mg per 5mL) ### Neonates (0-28 days) - **Dose**: **Contraindicated** - **Special Notes**: **Dicyclomine is contraindicated in infants < 6 months** due to high risk of respiratory distress, apnea, and seizures. ### Infants (1-12 months) - **Age 1-5 months**: **Contraindicated** (Dicyclomine component). - **Age 6-12 months (Use with extreme caution, only if clearly indicated by a physician)** - **Dose**: **2.5 mL (Dicyclomine 5 mg + Paracetamol 62.5 mg)** - **Frequency**: **3-4 times daily (TID-QID)** - **Route**: Oral - **Maximum**: Dicyclomine **20 mg/day**. Paracetamol **50 mg/kg/day**, max **750 mg/day** from this product. - **Special Notes**: Monitor closely for respiratory depression. ### Children (1-12 years) - **Indication**: Abdominal cramps/pain, associated fever. - **1-2 years** - **Dose**: **2.5-5 mL (Dicyclomine 5-10 mg + Paracetamol 62.5-125 mg)** - **Frequency**: **3-4 times daily (TID-QID)** - **Route**: Oral - **Maximum**: Dicyclomine **40 mg/day**. Paracetamol **50 mg/kg/day**. - **3-6 years** - **Dose**: **5 mL (Dicyclomine 10 mg + Paracetamol 125 mg)** - **Frequency**: **3-4 times daily (TID-QID)** - **Route**: Oral - **Maximum**: Dicyclomine **40 mg/day**. Paracetamol **50 mg/kg/day**. - **7-12 years** - **Dose**: **5-10 mL (Dicyclomine 10-20 mg + Paracetamol 125-250 mg)** - **Frequency**: **3-4 times daily (TID-QID)** - **Route**: Oral - **Maximum**: Dicyclomine **80 mg/day**. Paracetamol **50 mg/kg/day**, max **2000 mg/day**. ### Adolescents (13-18 years) - **Dose**: Generally follows **adult dosing** (tablet: **Dicyclomine 20 mg + Paracetamol 500 mg**). - **Frequency**: **Every 6-8 hours** as needed. - **Route**: Oral - **Maximum**: Dicyclomine **80 mg/day**. Paracetamol **4000 mg/day** (from all sources). ## Safety Information ### Contraindications - **Absolute (Dicyclomine)**: Obstructive uropathy, GI obstruction, reflux esophagitis, severe ulcerative colitis, myasthenia gravis, paralytic ileus, glaucoma, **infants < 6 months**. - **Absolute (Paracetamol)**: Severe hepatic impairment. - **Relative**: Tachycardia secondary to cardiac insufficiency, BPH (Dicyclomine). G6PD deficiency, active alcoholism (Paracetamol). ### Common Adverse Effects - **Very Common (>10%)**: Dry mouth (Dicyclomine). - **Common (1-10%)**: Blurred vision, dizziness, nausea, constipation, urinary hesitancy (Dicyclomine). Nausea, vomiting, mild rash (Paracetamol). - **Serious but Rare**: - Dicyclomine: Tachycardia, palpitations, respiratory distress/apnea (infants), confusion, psychosis. - Paracetamol: Hepatotoxicity (overdose), severe skin reactions (SJS, TEN). ### Key Drug Interactions - **Other Anticholinergics (e.g., TCAs, antihistamines)**: Potentiated anticholinergic effects (Dicyclomine). - **Opioids**: Increased risk of severe constipation or paralytic ileus (Dicyclomine). - **Digoxin**: Dicyclomine may increase digoxin levels due to delayed GI motility. - **Warfarin**: Paracetamol can increase INR, especially with chronic high doses. Monitor INR. - **Alcohol**: Increases risk of paracetamol-induced hepatotoxicity. ## Monitoring & Follow-up - **Before Treatment**: Assess for contraindications (e.g., glaucoma, BPH, GI obstruction), hepatic/renal function if patient has comorbidities. - **During Treatment**: - **Clinical Signs**: Monitor for anticholinergic side effects (e.g., dry mouth, blurred vision, urinary retention, constipation, confusion), and effectiveness of pain relief. - **Pediatric**: Closely observe infants/young children for signs of respiratory distress, feeding difficulties, or unusual somnolence. - **Overdose Risk**: Educate on total paracetamol intake from all sources to prevent hepatotoxicity. - **Clinical Judgement**: Reassess need for therapy; not intended for long-term chronic use. ## Clinical Pearls - 💡 **Combination drug**: Cyclopam contains both an antispasmodic (dicyclomine) and an analgesic/antipyretic (paracetamol). Be aware of effects and contraindications for both components. - 💡 **Pediatric Contraindication**: **Dicyclomine (and thus Cyclopam) is strictly contraindicated in infants younger than 6 months** due to serious safety concerns. - 💡 **Anticholinergic side effects**: Counsel patients on common effects like dry mouth, blurred vision, and constipation. Advise on sips of water, sugar-free candies, or artificial tears. - 💡 **Paracetamol overdose prevention**: Educate patients/parents on the maximum daily dose of paracetamol from *all sources* to avoid liver damage. - 💡 **Acute use only**: This medication is for acute, symptomatic relief of spasms and associated pain/fever, not for chronic management of underlying conditions. > **⚠️ Important**: This information is for educational purposes only.
