Study Notes

Preformulation and Formulation Studies

Preformulation and formulation studies are parallel in the drug development process.
In preformulation studies, the goal is to achieve the best form of a formulation for scale-up.
Precipitates must be avoided in solutions during preformulation studies.

Chemical Compounds and Polymorphism

Chemical compounds can exist in different forms depending on their chemical composition and method of isolation or crystallization.
Weak electrolytes or weakly basic/acidic compounds can exhibit polymorphism.

Partition Coefficient and Solubility

The partition coefficient of a certain weak electrolyte is important in determining its solubility.
Some solutions are highly dependent on temperature, affecting their solubility.

Project Context

The University of the Philippines - College of Pharmacy conducted a project with the code 7901.
The project likely involved early stage preformulation studies.

Compounding and Dosage Forms

Compounding involves preparing, mixing, assembling, altering, packaging, and labeling a medication.
Adding a vehicle (e.g., water) to a powder suspension is considered compounding.

Reasons for Creating Dosage Forms

Dosage forms are created to protect the drug from degradation after oral administration.
Some drugs need additional protection, such as enteric coating, to prevent degradation by enzymatic juices and ensure disintegration at the desired target site.

Preformulation Studies and Drug Development

Preformulation studies involve assessing the physical and chemical properties of a drug substance to determine its suitability for formulation.
Development of drugs and vaccines involves considering pharmaceutical and formulation considerations.

Insulin Properties and Stability

Insulin can exist in crystalline or amorphous forms.
If insulin exceeds its stability threshold, it indicates a failure in terms of its stability.

Preservatives and Shelf Life

Preservatives are added to ensure a product's stability throughout its shelf life.
The shelf life of a product is determined by the stability of the active pharmaceutical ingredient (API).

Pharmaceutical Solutions

A solution is a homogeneous mixture prepared by dissolving a solid, liquid, or gas in another liquid.
It represents a group of preparations in which the molecules of the solute or dissolved substance are dispersed among those of the solvents.

Advantages of Solutions

Completely homogeneous doses
Immediate availability for absorption and action
Easy to manufacture
Taken orally by patients who have difficulty in swallowing

Disadvantages of Solutions

Many drugs and chemicals are less stable in solution than they are in dry form
Not all drugs must be in solution
Not ideal for drugs with unpleasant taste
Some drugs are not soluble in solvents that are acceptable for pharmaceutical use
