SINCE Wwii, medical science has progressed with a stage where competitive medications are around for treat the same ailment in several people. This is not just about brands (that is a trade issue) but generic drugs (that is a scientific issue). In this report, we shall go through the various factors that decide selecting a specific drug.
Safety: The subsequent sub-criteria have to be considered underneath the criterion of safety:
* Acute therapeutic index: If your patient’s condition is acute, how effective is a particular drug even though it’s got certain side-effects so long as the acuteness in the condition is lowered? Example: narcotic pain-killers are amazing in healing pain but feature the opportunity side-effect of addiction.
* Long-term safety: medicine directory could possibly be safe in short-term treatment, so how safe it really is in long-term treatment? Example: antibiotics are acceptable in short-term treatment, but sometimes have undesirable effects in case of prolonged use.
* Drug-drug interaction risk: Medicines are chemicals, and lots of chemicals answer develop a different chemical, that have an effect which could harm the individual or aggravate his/her condition. Example: A tricyclic anti-depressant and alcohol interact to make a new condition that warrants separate treatment.
Drug-drug interaction risk is of 2 types:
· Pharmacokinetic: In this type of drug-drug interaction, two drugs, separate from each other, have certain effects one or maybe more 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) depends on because of its metabolism. This causes a boost in the side-effects of Lexapro.
· Pharmacodynamic: Here, a couple of drugs actually generate the same effect on the same organ, thus enhancing the total, added effect. Example: Lexapro has certain side-effects like drowsiness and fatigue. Darvocet-N also acts similarly for the brain. Thus, the side-effects of the two prescription medication is more serious.
Tolerability: A drug could possibly be effective but not tolerable by all patients. Example: Allergies to particular drugs in a few people. Short-term and long-term tolerability must be taken into consideration. Efficacy: A drug just isn’t equally efficient at all patients. For example, some patients with depression or anxiety disorders experience reduced escitalopram, but there are many that don’t, who therefore must be prescribed another anti-depressant. The rate of beginning of therapeutic action is an important key to be considered too.
Cost: Cost does not mean the cost of buying a particular medicine alone. It must also cover the cost of treatments for a complication which could arise by using another drug. Example: In the individual that insists on taking alcohol nevertheless needs to be treated for depression is often administered an SSRI drug because they drugs don’t potentiate the effects of alcohol, whereas another band of anti-depressants (like tricyclics) may cause a fresh overuse injury in such patients, which would need a different and expensive treatment. Therefore, it’s better to prescribe the more expensive escitalopram instead of a cheaper tricyclic such patients.
Simplicity of treatment: The best mode of administration is preferred. If you have an option between an injection and oral administration, the second is preferred in the event the efficacy of the two modes can be compared. Or, local application is chosen over the oral route where possible; e.g., antibiotic treatments for eye infections. Dosage and frequency of administration too are a key point to choose simplicity of treatment.
