oral liquid dosage

helping the medicine go down

Oral liquid dosage forms are liquid-state pharmaceutical preparations for oral administration, often used when patients have difficulty swallowing solid dosage forms like tablets or capsules or when dose flexibility is necessary. Oral liquid dosage forms are available in various forms such as solutions, suspensions, emulsions, and syrups. 

Appropriate excipients may be added to oral liquid dosage forms to improve stability, palatability, and appearance, making them more acceptable to patients, especially children. Oral liquid dosage forms may require refrigeration or special storage conditions depending on their formulation, and they usually have a shorter shelf life compared to solid dosage forms. 

Ashland offers:

  • natrosol™ 250 m pharm hydroxyethylcellulose that is a thickener/viscosity modifier easily dispersed in cold or hot water to give solutions of varying viscosities and desired properties, although it is insoluble in organic solvents. It is used in solutions to control rheology, stable over a broad pH range, and suitable to match typical viscosity profiles of pharmaceutical syrups

  • CAVASOL* and CAVAMAX* cyclodextrins that improve solubility of poorly soluble compounds; the same mechanism makes these excipients capable of masking unpleasant taste/odor and stabilizing APIs that are prone to degradation.

  • plasdone™ K-12 povidone that is used to enhance the solubility of active pharmaceutical ingredients, increase bioavailability, and inhibit recrystallization of ingredients in pharmaceutical syrups.

  • blanose™ sodium carboxymethylcellulose (CMC) that are used as thickeners and suspending aids for syrups and suspensions

The molecular structure of cyclodextrins creates a bucket-like cavity that can complex with molecules or functional groups on molecules to improve solubility of poorly soluble compounds. The same mechanism makes these excipients capable of masking unpleasant taste/odor and stabilizing drugs that are prone to degradation. The number of glucose units in the ring determines the internal diameter of the cavity and its volume, as the height of the cyc...

Natrosol™ pharm HEC grades are non-ionic, water-soluble polymer widely used in pharmaceutical formulations. This product is easily dispersed in cold or hot water to give solutions of varying viscosities and desired properties, though it is insoluble in organic solvents. It is used in solutions and gels to control rheology, in emulsions for high-salt tolerance and surfactant compatibility, and in modified-release matrix tablets where high-vi...
