What factors affect a medications action?

Factors influencing drug effects

• Type of drug.
• Quantity of drug used.
• Method of drug use.
• Time taken to consume.
• Tolerance.
• Gender, size and amount of muscle.
• Use of other psycho-active drugs.
• Mood or attitude.

What are three factors that can affect a medications action?

The effect of any drug on an individual is the result of three interacting factors: the drug itself. the individual user. the environment in which drug use occurs.

What factors affect drug dosages?

Shalini S. Lynch

• Genetic makeup.
• Age.
• Body size.
• Use of other drugs and dietary supplements (such as medicinal herbs.
• Consumption of food (including beverages)
• Presence of diseases (such as kidney or liver disease)
• Storage of the drug (whether the drug was stored too long or in the wrong environment)

What can cause a decrease in medication effectiveness?

4 Reasons Medications May Not Work Properly

• Patients are not taking medications exactly as directed.
• A patient’s diet may be interfering with medications.
• A patient’s lifestyle habits may be interfering with medications.
• A patient may have comorbid conditions.

What is pharmaceutical effect?

Pharmacological effects of drugs (i.e. their effects on cells, organs and systems) are, in principle, simple to measure in animals, and often also in humans. We can measure effects on blood pressure, plasma cholesterol concentration, cognitive function, etc., without difficulty.

What is factor influencing of dosages form?

Physiological variables include the time of dosing relative to the phase of the interdigestive migrating myoelectric current (IMMC), the sieving properties of the pylorus, the presence or absence of food, and the inherent crushing force of the stomach.

What do you mean by Adme of a drug explain different factors affecting drug action?

ADME is an abbreviation in pharmacokinetics and pharmacology for “absorption, distribution, metabolism, and excretion”, and describes the disposition of a pharmaceutical compound within an organism.

What causes medications to stop working?

Hormonal issues, poor metabolism, poor sleep, high blood pressure, or stomach conditions could change the effect of your medications. It is important to inform all of your doctors about any other conditions you may have to help avoid these problems.

Which of the following factors increases the risk of an adverse drug reaction?

Factors which might increase the possibility of the occurrence of ADRs include; extremes of age, gender, multiple drugs, disease state, past history of ADR or allergy, genetic factors, large doses and many other factors.

What are the factors affecting adsorption?

What is Adsorption?

• Factors affecting the extent of adsorption. The extent to which adsorption will happen on a solid surface depends on the following factors:
• Nature of adsorbent. The adsorption of the gas depends on the nature of the adsorbent.
• Surface area.
• Nature of the gas.
• Exothermic nature.
• Pressure.

What are the factors affecting drug distribution?

Several factors impact drug distribution. These factors include the concentration of drug transporters in blood, pH, perfusion, body water composition, body fat composition, and most certainly disease conditions (e.g., volume depletion, burns, third spacing).

Why are factors important in modifying drug effect?

Hence factors that modify pharmacological pattern of drugs assume greater significance in modifying drug response since a given pharmacological effect would generally appear at a similar blood level in all species. Generally, man is assumed to be six times as sensitive as dog, and ten times as sensitive as rat to the drug effects.

How does your body affect the amount of medicine you take?

For example, changes in the digestive system can affect how fast medicines enter the bloodstream. Changes in body weight can influence the amount of medicine you need to take and how long it stays in your body. The circulatory system may slow down, which can affect how fast drugs get to the liver and kidneys.

How does a pathological state affect a drug’s effect?

Pathological Factors: Several pathological states particularly those affecting liver, kidney or altering body fluid pH and electrolytes are known to affect drug, effects and drug dosage. Organic or systemic alterations can markedly alter pharmaco-kinetics and/or pharmacodynamics of a drug in affected species.

When do two drugs produce the same effect?

(a) Addition : When two or more drugs given together produce the same resulting effect is the algebric sum of their individual effects e.g., carbachol and acetycholine. (b) Synergism : In synergism, the effect produced is greater than the algebric sum of the effects due to individual drugs e.g., adrenaline and cocaine.
