Introduction
Tadalafil powder is the raw active pharmaceutical ingredient (API) used to make Cialis® and Adcirca®. While not intended for direct consumer use in raw form, it is widely handled by pharmaceutical manufacturers, compounding pharmacies, and research labs. Understanding how to correctly measure, mix, and prepare Tadalafil powder is critical for ensuring accuracy, stability, and safety.
This guide explains dosage forms, mixing protocols, liquid preparation methods, and lab considerations when working with Tadalafil raw powder.

Recommended Dosage Forms
Tadalafil powder is not consumed directly but converted into dosage forms.
Clinical Reference Doses (Cialis® & Adcirca®):
- Erectile Dysfunction (ED): 10–20 mg on demand.
- Daily ED or BPH: 2.5–5 mg once daily.
- Pulmonary Arterial Hypertension (PAH): 40 mg daily (Adcirca®).
📌 Note: These values are for approved tablet formulations, not for raw powder self-use. Actual dosing must be determined by a healthcare professional.

Measuring Tadalafil Powder
- Precision Scales: Always use laboratory-grade milligram scales (±0.001 g accuracy).
- Calibration: Regularly calibrate to avoid under/over-dosing.
- Batch Recording: Log each batch with weight, date, and operator for traceability.
⚠️ Red Flag: Kitchen scales or non-calibrated equipment cannot accurately measure small pharmaceutical doses.
Mixing Tadalafil Powder
For formulation development, Tadalafil powder may be blended with excipients:
- Solid Mixtures
- Mix with microcrystalline cellulose, lactose, or mannitol.
- Use a V-blender or mortar/pestle for small batches.
- Capsules
- Powder can be filled into capsules with excipients to improve uniformity.
- Custom Lab Blends
- RUO labs often test micronized powder for improved dissolution.
Preparing Tadalafil Liquid from Powder
Since Tadalafil is sparingly soluble in water, special solvents and mixing techniques are required.
Steps for Oral Suspensions (Compounding Pharmacies):
- Solvent Choice: Use ethanol, propylene glycol, or a co-solvent system (e.g., ethanol + PEG).
- Dissolution: Stir or sonicate until fully dissolved.
- Suspension: Add flavoring or sweetening agents if for patient-specific oral liquid.
- Storage: Store refrigerated (2–8°C); stability varies by formulation.
Stability Notes:
- Powder stable 24–36 months sealed; liquid suspensions stable 30–60 days.
- Always confirm with accelerated stability tests (ICH Q1A).

Practical Lab Applications
- PK/PD Studies: Dissolved Tadalafil powder used in preclinical animal dosing.
- Formulation Trials: Used in ODTs (orally disintegrating tablets), oral thin films, and nanoparticle suspensions.
- Compounding Pharmacies: Create custom suspensions and low-dose formulations for ED/BPH.

Buyer & User Precautions
- Never consume raw powder directly.
- Only work under GMP or research protocols.
- Always demand COA, MSDS, GMP certificate from suppliers.
- Ensure proper PPE when handling: gloves, goggles, lab coat, dust mask.
Conclusion
Tadalafil powder is a flexible API that can be transformed into tablets, capsules, suspensions, or research formulations. Correct measuring, mixing, and preparation protocols are essential to maintain safety and efficacy.
Key Takeaways:
- Use precision scales for accurate dosing.
- Mix with excipients for solid dosage or solvents for suspensions.
- Powder stable for up to 3 years; suspensions stable for ~2 months.
- Work only under professional supervision with full documentation.
📌 Next Steps:
