Asthma Attacks Every Morning, Treatment For It?

Hello, My father has been an asthma patient for a long time and gets an attack almost every morning, stays for a couple of hours and gets better eventually, for a few days now he is starting to get the attack many time during the day, he was prescribed Omnacortil in but that did not make any improvement to his health, we plan to start the treatment as fresh soon, need your suggestions on what to keep in mind and expect and any off hand suggestions to not let the situation get worse, would be appretiated . Thanks
