Compounded Creams in Our Pharmacy Laboratory: Personalised Topical Preparations with Scientific Precision

Personalised topical care through pharmacy compounding

At our pharmacy, we operate a dedicated galenic laboratory where we can prepare personalised topical formulations, such as compounded creams, ointments, gels and other semi-solid preparations, when there is a valid medical prescription or clear therapeutic instruction for an individual patient.

Compounded creams are not mass-produced cosmetic products. They are pharmaceutical preparations made for a specific person, based on the therapeutic need assessed by the prescriber and prepared by the pharmacist with professional responsibility.

This service allows the pharmacy to support personalised dermatological care when a standard ready-made product is not suitable, not available, or does not meet the exact requirements of the prescription.

What are compounded creams?

Compounded creams are semi-solid topical preparations made in a pharmacy laboratory by combining one or more prescribed ingredients with a suitable cream base.

Depending on the prescription and the intended use, the pharmacist may prepare different types of topical formulations, including:

• creams,

• ointments,

• gels,

• lotions,

• pastes,

• emulsions,

• moisturising bases,

• dermatological vehicles for active ingredients.

Each texture has different characteristics. Some preparations are lighter and easier to spread, while others are richer, more occlusive or more suitable for dry skin areas. The choice of base and texture is part of the pharmaceutical formulation process.

Why do pharmacies prepare compounded creams?

Pharmacies prepare compounded creams to meet individual patient needs that may not be fully covered by standard commercial products.

A compounded topical preparation may be useful when the doctor prescribes:

• a specific strength of an active ingredient,

• a combination of ingredients in one preparation,

• a particular texture or base,

• a preparation suitable for a specific skin area,

• an alternative form when a ready-made product is not appropriate,

• a personalised topical medication for an individual patient.

Compounded creams are prepared only when there is a prescription or clear therapeutic instruction. The pharmacist then evaluates whether the preparation can be made appropriately, safely and consistently in the pharmacy laboratory.

Who decides that a compounded cream should be prepared?

The decision to use a compounded cream begins with the prescriber.

The doctor evaluates the patient’s condition and writes the prescription or therapeutic instruction. The pharmacist then executes the prescription by preparing the topical formulation in the laboratory.

In simple terms:

The doctor determines the therapeutic need.
The pharmacist prepares and dispenses the formulation.

The pharmacist does not replace the doctor’s role. Instead, the pharmacist uses pharmaceutical knowledge to prepare the prescribed formulation correctly, choose the appropriate base, ensure proper mixing, apply quality procedures and provide clear instructions for use.

The legal and professional framework for galenic preparations

In the European framework, a magistral formula is a medicinal product prepared in a pharmacy in accordance with a medical prescription for an individual patient. This concept supports the preparation of personalised medicines in the pharmacy when there is a patient-specific prescription.

Galenic preparations, including compounded creams, are therefore not promoted as general ready-made products. They are prepared for individual needs, within the professional and legal framework of pharmacy practice.

The pharmacy laboratory must operate with order, cleanliness, appropriate equipment and responsible procedures. Quality in compounding depends on accurate calculations, correct weighing, suitable ingredients, controlled preparation and proper labelling.

Different cream bases and textures

One of the most important parts of preparing compounded creams is choosing the correct base.

The base is not just a “carrier.” It affects the texture, spreadability, skin feel, absorption profile and overall suitability of the preparation.

Depending on the prescription and the area of application, the pharmacist may select a base that is:

• light and easily absorbed,

• richer and more moisturising,

• oil-in-water,

• water-in-oil,

• gel-like,

• non-greasy,

• more occlusive,

• suitable for sensitive areas,

• appropriate for dry, oily or irritated skin,

• compatible with the prescribed active ingredient.

Different bases behave differently. Some are better for large skin areas, some for localised application, some for dry skin and some for areas where a lighter texture is preferred.

This is why the selection of the cream base is a scientific decision made by the pharmacist according to the prescription, the active ingredients, the patient’s needs and the intended use.

Why accurate weighing matters

In compounded creams, accuracy starts with weighing.

Each ingredient must be measured carefully using suitable laboratory scales. Accurate weighing helps ensure that the preparation corresponds to the prescribed formula.

The pharmacist checks:

• the active ingredients,

• the quantity required,

• the total final amount,

• the selected base,

• the compatibility of ingredients,

• the appropriate method of incorporation,

• the correct packaging and labelling.

Precise weighing is essential because even small deviations can affect the quality and consistency of the final preparation.

Professional mixing equipment for compounded creams

The quality of a compounded cream depends not only on the ingredients but also on how they are mixed.

In our pharmacy laboratory, compounded creams are prepared using appropriate equipment for semi-solid formulations. Professional cream mixing equipment helps achieve a more uniform texture and better distribution of ingredients throughout the base.

Using a cream mixing machine can support:

• better homogenisation,

• smoother texture,

• consistent distribution of active ingredients,

• reduced manual handling,

• improved reproducibility,

• better control of the mixing process,

• a more professional final preparation.

The aim is to create a uniform preparation where the active ingredient is distributed as evenly as possible within the cream base.

How compounded creams are prepared step by step

Below is an overview of the typical process used in a pharmacy laboratory for preparing compounded creams.

1. Prescription review

The process begins with a careful review of the medical prescription or therapeutic instruction.

The pharmacist checks:

• the patient details,

• the prescribed active ingredient or ingredients,

• the concentration or quantity required,

• the final amount to be prepared,

• the dosage instructions,

• the area of application,

• any special instructions from the prescriber.

If the prescription is unclear, the pharmacist may contact the prescriber before proceeding.

2. Pharmaceutical assessment of the formula

Before preparation, the pharmacist assesses whether the formula is suitable for compounding.

This includes checking:

• ingredient compatibility,

• appropriate base selection,

• concentration limits,

• texture requirements,

• stability considerations,

• suitability of packaging,

• storage requirements.

This step is important because not every ingredient behaves the same way in every base.

3. Selection of the cream base

The pharmacist chooses the appropriate base according to the prescription and the intended use.

A light cream base may be selected for easier spreadability. A richer base may be preferred for drier areas. A gel base may be chosen when a lighter, cooling or non-greasy texture is needed.

The base must be suitable for the active ingredient and for the area where the preparation will be applied.

4. Preparation of the workspace and equipment

Before the preparation begins, the laboratory area and equipment are prepared.

This includes:

• cleaning the work surface,

• selecting appropriate utensils,

• preparing the weighing equipment,

• preparing the mixing equipment,

• checking containers and packaging,

• ensuring that ingredients are correctly identified.

A clean, organised workspace supports accuracy and reduces the risk of errors.

5. Accurate weighing of ingredients

The pharmacist weighs the active ingredients and the base using appropriate laboratory scales.

Each ingredient is measured carefully according to the prescription. The weighing process is one of the most important quality steps in the preparation.

6. Incorporation of active ingredients

The active ingredient is incorporated into the base using a suitable technique.

Depending on the ingredient, this may require:

• levigation,

• gradual incorporation,

• geometric dilution,

• pre-mixing with a suitable vehicle,

• controlled addition into the base.

The goal is to avoid lumps, uneven distribution or separation of the formulation.

7. Mixing and homogenisation

The preparation is mixed until the texture becomes uniform.

When appropriate, a professional cream mixing machine may be used to improve homogenisation and consistency.

Proper mixing helps ensure that the active ingredient is distributed throughout the preparation and that the final cream has a smooth and professional texture.

8. Visual and physical quality check

After mixing, the pharmacist checks the preparation.

This may include checking:

• texture,

• colour,

• homogeneity,

• absence of visible lumps,

• absence of separation,

• smoothness,

• consistency,

• suitability for packaging.

A compounded cream should look uniform and should be appropriate for the intended route of administration.

Quality and safety in our pharmacy laboratory

Our laboratory process is based on accuracy, cleanliness and pharmaceutical responsibility.

For every compounded cream, we focus on:

• correct prescription execution,

• suitable base selection,

• accurate weighing,

• appropriate mixing,

• proper homogenisation,

• controlled preparation conditions,

• final quality checks,

• correct packaging,

• clear labelling,

• patient counselling.

Compounding is a scientific service. It requires knowledge of pharmaceutical forms, ingredient behaviour, base compatibility and preparation techniques.

What patients should know about compounded creams

Compounded creams are prepared specifically for the patient named in the prescription. They should be used only as instructed by the doctor and pharmacist.

Patients should also know that:

• compounded creams are not general cosmetic products,

• they are prepared according to a prescription,

• they should not be shared with others,

• they should be stored according to the label,

• they should be used only for the intended area,

• they should be kept away from children,

• the pharmacist should be contacted if there are questions about use, storage or appearance.

Conclusion

Compounded creams are an important part of personalised pharmacy care. They allow the pharmacist to prepare a topical formulation according to the specific prescription written by the doctor and the needs of the individual patient.

In our pharmacy laboratory, we combine scientific knowledge, suitable bases, accurate weighing, professional mixing equipment and quality-focused procedures to prepare compounded creams with care, precision and responsibility.
