SINCE World war 2, medical science has progressed to a stage where competitive medications are around to treat exactly the same ailment in different people. This is simply not pretty much brands (that is a trade issue) but generic drugs (that is a scientific issue). With this report, we shall consider the various factors that decide your selection of a certain drug.
Safety: These sub-criteria has to be considered underneath the criterion of safety:
* Acute therapeutic index: In the event the patient’s condition is acute, how effective is a particular drug even when they have certain side-effects providing the acuteness in the condition is lowered? Example: narcotic pain-killers are incredible in healing pain but feature the opportunity side-effect of addiction.
* Long-term safety: medicine directory may be safe in short-term treatment, but wait, how safe it can be in long-term treatment? Example: antibiotics are acceptable in short-term treatment, but tend to have undesirable effects in the case of prolonged use.
* Drug-drug interaction risk: Drugs are chemicals, and many chemicals reply to create a different chemical, which has an effect that will harm the individual or aggravate his/her condition. Example: A tricyclic anti-depressant and alcohol interact to create a new condition that warrants separate treatment.
Drug-drug interaction risk is of 2 types:
· Pharmacokinetic: In this kind of drug-drug interaction, two drugs, separate from each other, have certain effects on one or higher body processes (e.g., metabolism) that affects the performance in the other. Example: Darvocet-N (propoxyphene and acetaminophen) inhibits the act of a liver enzyme that Lexapro (escitalopram) is determined by for the metabolism. This will cause more the side-effects of Lexapro.
· Pharmacodynamic: Here, several drugs actually generate the same impact on exactly the same organ, thus improving the total, added effect. Example: Lexapro has certain side-effects such as drowsiness and fatigue. Darvocet-N also acts similarly around the brain. Thus, the side-effects of the two medicines are more serious.
Tolerability: A medication may be effective however, not tolerable by all patients. Example: Allergies to a particular drugs in most people. Short-term and long-term tolerability should be taken into account. Efficacy: A medication isn’t equally efficient at all patients. By way of example, some patients with depression or anxiety disorders experience respite from escitalopram, but there are several that do not, who therefore should be prescribed an alternative anti-depressant. The rate of beginning of therapeutic action is an important key to be regarded as too.
Cost: Cost doesn’t imply the price tag on purchase of a particular medicine alone. It ought to also cover the price tag on treatments for a complication that will arise from using an alternative drug. Example: In a individual that insists on taking alcohol but has to be treated for depression is often administered an SSRI drug because these drugs don’t potentiate the effects of alcohol, whereas another gang of anti-depressants (such as tricyclics) can cause a whole new condition in such patients, which will need a different and expensive treatment. Therefore, it’s easier to prescribe the more costly escitalopram as opposed to a cheaper tricyclic such patients.
Simplicity of treatment: The simplest mode of administration is preferred. If you find an alternative between an injection and oral administration, aforementioned is preferred if your efficacy of the two modes is analogous. Or, local application is preferred to the oral route where possible; e.g., antibiotic treatments for eye infections. Dosage and frequency of administration too are a key factor to make a decision simple treatment.
