Study Notes

Disadvantages of Pharmaceutical Solutions

  • Instability of drugs in solution dosage forms can be initiated by heat, light, peroxides, or heavy metals.
  • Pharmaceutical solutions can be bulky to carry around, which can be a problem.
  • Solutions can be susceptible to hydrolysis, which can lead to degradation.

Advantages of Pharmaceutical Solutions

  • Pharmaceutical solutions can be an advantage for people with swallowing difficulties, such as children and some adults.

Routes of Administration

  • Syrups, elixirs, and drops are used in the oral route of administration.

Stability Issues

  • Pharmaceutical solutions can be prone to degradation due to stability issues, which is a disadvantage.

Minimizing Contamination

  • Chelating agents can be used to minimize the effect of trace metals in pharmaceutical solutions.
  • Plastic containers should not be used if a light-resistant container is specified, as they may allow light to penetrate and affect the solution.
  • Water and other liquids can be carriers of bacteria that ultimately contaminate pharmaceutical products.
  • Moist areas, such as pipes and valves, are where bacteria grow well in pharmaceutical equipment.
  • People are the most important carrier of contaminants contributing to product contamination.

Preservatives

  • Benzoic acid is a type of preservative that is effective in acid media due to its non-ionized form, and is used in a concentration range of 0.05-0.1%.
  • Paraben esters are employed at concentrations up to 0.2% as preservatives.
  • Propylene glycol is used as a solvent, humectant, and preservative in pharmaceutical preparations.
