Class Molecules to Medicine

Dosage Forms that Favour Drug Solubility

Micelles

Liposomes

Cyclodextrins



Micelles

Micelles are formed by surfactants (Traps dirt for removal)

Surfactants are amphiphilic (Hydrophilic head w/ hydrophobic tail)

Arranged in a way to minimise contact between hydrophobic tail and
solvent

Low concentrations for an alignment on water surfaces

Higher concentrations allow surfactants to assemble into micelles

Micelle cores trap hydrophobic drugs



Osmotic Pressure

Depends on concentration of solute inside a solution

Adding more surfactant molecules doesn’t increase it’s quantity once a
certain concentration is reached. The molecules only add to the micelle
