Detailed Answer:
Thank you for asking

I read your question and I understand your concern. From the list if medications you mentioned Ranexa and metoprolol are the commonest notorious causes of this dry mouth and poor taste. Here is what your doctor can do

> Change medications that cause dry mouth. If your doctor believes medication to be the cause, he or she may adjust your dosage or switch you to another medication that doesn't cause a dry mouth.

> Recommend products to moisturize your mouth. These can include prescription or over-the-counter mouth rinses, artificial saliva or moisturizers to lubricate your mouth.

If you have severe dry mouth, your doctor or dentist may:

> Prescribe medication that stimulates saliva. Your doctor may consider prescribing pilocarpine (Salagen) or cevimeline (Evoxac) to stimulate saliva production.

> Protect your teeth. To prevent cavities, your dentist might fit you for fluoride trays, which you fill with fluoride and wear over your teeth for a few minutes at night. Your dentist may also recommend weekly use of a chlorhexidine rinse to control cavities.

Here is what you can do at home.

> Sip water or sugar-free drinks or suck ice chips throughout the day to moisten your mouth, and drink water during meals to aid chewing and swallowing.

> Chew sugar-free gum or suck on sugar-free hard candies. However, in some people, xylitol, which is often found in sugar-free gum or sugar-free candies, may cause diarrhea or cramps if consumed in large amounts.

> Try over-the-counter saliva substitutes that contain carboxymethylcellulose (kahr-bok-see-meth-ul-SEL-u-lohs) or hydroxyethyl cellulose (hi-drok-see-ETH-ul SEL-u-lohs), such as Biotene Oral Balance.

> Breathe through your nose, not your mouth. You may need to seek treatment for snoring that causes you to breathe through your mouth during the night.

> Add moisture to the air at night with a room humidifier.

>Moisturize your lips to soothe dry or cracked areas.

Avoid products that can make your symptoms worse. These include:

> Caffeine and alcohol. These products can cause dryness and irritation. Don't use a mouthwash that contains alcohol.

>Stop All tobacco. If you smoke or chew tobacco, stop, because tobacco products can dry and irritate your mouth.

> Over-the-counter antihistamines and decongestants. These can worsen your dry mouth.

> Sugary or acidic foods and candies. They increase the risk of tooth decay. Also avoid spicy or salty food because they can cause irritation.

>Saliva is important to maintain the health of your teeth and mouth. Taking these steps to protect your teeth may also help your dry mouth condition:

> Brush with a fluoride toothpaste and floss your teeth. Ask your dentist if you might benefit from prescription fluoride toothpaste, toothpaste containing betaine, or a tooth gel to neutralize bacteria acids.
Use a fluoride rinse or brush-on fluoride gel before bedtime.
See your dentist at least twice yearly to have your teeth examined and plaque removed, to help prevent tooth decay.

I hope it helps. Take good care of yourself and don't forget to close the discussion please.
