Study Notes

Considerations for Pharmaceutical Solutions

Chemical availability, sterilization of final solution, drug and buffer stability over time, material cost, and toxicity freedom should be considered.
Cell swelling and lysis can occur as a result of osmotic pressures.

Isotonic Solutions in Biology and Pharmaceutics

Isotonic solutions are used in biology and pharmaceutics to prevent osmotic pressure effects.
Borate buffer is toxic and cannot be used to stabilize oral or parenteral solutions.
