Drugs and Their Side Effects on the Human Body

Did you know all drugs have side-effects they pose to the human body? The effects are however not the same for all people. What one may experience after taking certain drugs can be totally different from the experiences of another person on the same drugs. How the body reacts to these drugs and causes side effects are dependent on a number of factors. These factors can either be patient-related, socially related, or drugs-related. This article will enlighten you on what susceptibility you may be having against certain drugs, their reactions and most importantly how to manage them after you buy Wellbutrin online in Canada.

Vulnerability to Side Effects

Every person is unique in their own way, so some people are more susceptible to the side effects of drugs that others. The most dominant factor determining this being a person’s age as older people and infants tend to have adverse reactions towards medications. This is because children have smaller bodies that tend to metabolize medication much slower from the stomach but do possess faster intramuscular (IM) rate of absorption. With them, the permeability of the blood-brain barrier is slightly higher than that of adults. So you need to consider all these factors when you buy Wellbutrin online in Canada.

Adults and Drugs

Mature adults are more susceptible to drug side effects as they take more medication than infants. In fact, they are two times more likely to experience adverse drug effects and at least 7 times more likely to be admitted to a hospital as a result of the same. Most adults actually hang between experiencing the effectiveness of certain medications or rather their toxicity for instance insulin, anti-seizure drugs or even warfarin. With the fat levels exceeding the water in their bodies, certain drug effects may be elongated as more time passes during their metabolism and absorption.
Adults also experience reduced metabolism and excretion in both their liver and kidney. The adult brain is furthermore extra sensitive to the sedating effect most drugs have, thus causing dizziness, ear and eye complications interfering with their body balance.

Patient-Related Factors Increasing the Risk

There are many factors that could also determine how you respond to a certain drug. Below is a list of different factors that one could attribute to the vulnerability experienced when undertaking certain medications.


Did you know that genetic factors contribute to about 20-90% of the variability of patients when dealing with their medication? The study of how genes can influence the way your body reacts to medication is called pharmacogenetics. In this sector, the tests for liver enzyme discrepancies are becoming more common.

or instance, the human body metabolizes codeine to create morphine, a pain-relieving substance prescribed for killing pain. What most people don’t know is that the conversion rate of the induced codeine to morphine depends on your metabolism. This means that only poor metabolizers, which consist of up to 10% of patients, are unable to benefit from the pain-relieving ability of morphine while another 2% of the patient population are ultra-rapid metabolizers. These ultra-rapid metabolizers, may also fail to benefit from the codeine as more of the substance is converted to morphine, subjecting them to the possibility of adverse toxic reactions.
