Final answer:
The two word forms to identify anti-migraine drugs are: abortive (or acute) and preventive (or prophylactic), for immediate relief and for reducing the frequency of attacks, respectively.
Step-by-step explanation:
The two word forms used to identify anti-migraine drugs are abortive or acute treatments and preventive or prophylactic treatments.
Abortive treatments are medications taken at the onset of a migraine attack to relieve immediate symptoms. Examples include triptans, which are serotonin receptor agonists, and nonsteroidal anti-inflammatory drugs (NSAIDs). On the other hand, preventive treatments are medications prescribed to be taken regularly to reduce the frequency and severity of migraine attacks. These include beta-blockers, antiepileptic drugs, and certain antidepressants.
It is essential to use the correct form of medication based on the individual patient's needs, the characteristics of their migraine attacks, and the guidance of a healthcare provider. Ongoing research continues to bring forth new treatment options within these two categories of anti-migraine medication, aimed to improve the quality of life for those suffering from migraines.
