SINCE World war 2, medical science has progressed with a stage where competitive medications are for sale to treat exactly the same ailment in different people. This isn’t nearly brands (that is a trade issue) but generic drugs (that is a scientific issue). In this report, we shall consider the various factors that decide your selection of a certain drug.

Safety: The subsequent sub-criteria must be considered within the criterion of safety:

* Acute therapeutic index: In the event the patient’s condition is acute, how effective is a particular drug even if it’s certain side-effects as long as the acuteness from the condition is lowered? Example: narcotic pain-killers are incredible in healing pain but feature the possibility side-effect of addiction.

* Long-term safety: medicationdirectory.com might be safe in short-term treatment, but how safe it really is in long-term treatment? Example: antibiotics are acceptable in short-term treatment, but could have undesirable effects in case of prolonged use.

* Drug-drug interaction risk: Medicines are chemicals, and many chemicals answer produce a different chemical, which has an effect which could 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 two sorts:

· Pharmacokinetic: In this type of drug-drug interaction, two drugs, outside of one another, have certain effects one or maybe more body processes (e.g., metabolism) that affects the performance from the other. Example: Darvocet-N (propoxyphene and acetaminophen) inhibits the action of a liver enzyme that Lexapro (escitalopram) depends upon due to the metabolism. This leads to a boost in the side-effects of Lexapro.

· Pharmacodynamic: Here, several drugs actually produce the same effect on exactly the same organ, thus helping the total, added effect. Example: Lexapro has certain side-effects for example drowsiness and fatigue. Darvocet-N also acts similarly about the brain. Thus, the side-effects of both medicines are more intense.

Tolerability: A drug might be effective but not tolerable by all patients. Example: Allergies to particular drugs in certain people. Short-term and long-term tolerability should be looked at. Efficacy: A drug just isn’t equally great at all patients. For example, some patients with depression or anxiety disorders experience reduced escitalopram, but there are many that don’t, who therefore should be prescribed a different anti-depressant. The interest rate of beginning of therapeutic action is a crucial key to be considered too.

Cost: Cost does not always mean the price tag on purchase of a particular medicine alone. It ought to also cover the price tag on treatment of a complication which could arise from using a different drug. Example: In a individual that insists on taking alcohol but must be treated for depression is generally administered an SSRI drug because they drugs don’t potentiate the consequences of alcohol, whereas another gang of anti-depressants (for example tricyclics) might cause a brand new problem in such patients, which will need a different and expensive treatment. Therefore, it’s better to prescribe the more expensive escitalopram instead of a cheaper tricyclic in this patients.

Simple treatment: The easiest mode of administration is preferred. When there is an alternative between an injection and oral administration, aforementioned is preferred in the event the efficacy of both modes is the identical. Or, local application is preferred to the oral route where possible; e.g., antibiotic treatment of eye infections. Dosage and frequency of administration too are a key point to choose simplicity of treatment.
