What is incompatibility pharmacy?

Incompatibility is an undesirable reaction that occurs between the drug and the solution, container or another drug. The two types of incompatibilities associated with intravenous administration are physical and chemical.

What factors may impact a patient’s compliance?

This list of potential barriers included:

  • Demographic factors such as age, ethnicity, gender, education, marriage status.
  • Psychosocial factors: beliefs, motivation, attitude.
  • Patient-prescriber relationship.
  • Health literacy.
  • Patient knowledge.
  • Physical difficulties.
  • Tobacco or alcohol intake.
  • Forgetfulness.

How does genetics affect drug response?

Individuals who do not respond to medications as expected may have genetic differences that change the amount of enzymes available to break down a medication or may cause the enzymes not to work. These genetic differences may have an effect on how someone responds to a medication.

What are some factors that affect medication compliance?

Previous research has indicated that adherence is influenced by a number of issues, including side effects, cost of the medication, dosing frequency, and routes of administration. Other factors include patient beliefs, demographics and comorbidities.

What are examples of physiological factors?

The physiological factors include how people feel, their physical health, and their levels of fatigue at the time of learning, the quality of the food and drink they have consumed, their age, etc. Think of some physiological factors that are important when you try to study or learn something new for yourself.

How does disease affect drug response?

The absorption, distribution, metabolism, and elimination (ADME) of drugs can be influenced by the physiological and biochemical changes that occur due to various diseases. These changes can have dramatic influence on the exposure of drugs and lead to drug toxicity or lack of drug efficacy.

How does age affect drug response?

In general, as we age, total body water and muscle mass decrease while percentage of body fat increases. These changes can lead to drugs having a longer duration of action and increased effect. Drugs that were effective may become compounded and overexceed their therapeutic threshhold causing increased side effects.

When two or more drugs are used in the combination form their action is increased the phenomena is called?

Drug synergism arises when the therapeutic effect of two or more drugs used in combination is greater than the sum of the effects of the drugs administered individually.

What are the types of prescription?

  1. Opioids.
  2. Central Nervous System (CNS) Depressants.
