If a drug taken for one condition (e. g., bone loss) also inhibits smooth muscle contraction, what side effects might the drug have?

Trouble swallowing (Dysphagia)

Explanation:

Trouble swallowing also known as dysphagia is caused by difficulty with nerves and muscles cells in the mouth and throat when swallowing drug substances. What literally happens when swallowing is that, the airways folds up and closes and breathing skips for a moment to allow push down of the substance down the oesophagus into the gut system. The push down is done by the floor of the tongue located at the ventral surface.

The ventral surface of the tongue consist of  a stratified squamous non-keratinized epithelium muscle cells which is smooth. When a drug taken for one condition (e.g., bone loss)  and also inhibits smooth muscle contraction, it also affects the tongue thereby causing troubled swallowing.
