Li-ion tsa calcium li bohlokoa haholo bakeng sa ho tlama lits'ebetso tse hlahang holim'a seleng ea sele le mekhoa ea intracellular. Sena se etsahala ka mechine ea ione, eo ka eona mefuta e meng ea limolek'hule tsa protheine e bulelang tsela ea li-ion ea calcium.
Sebaka le karolo ea litsela tsa ion
Litsamaiso tsena, ka lehlakoreng le leng, li arotsoe ka mefuta e meraro:
- cytoplasmic;
- sakrolemalnye;
- entracellular.
Litsamaiso tse ngata tsa khalsiamo li ka har'a mesifa ea pelo, 'me tse setseng li mahetleng a mesifa ea bronchi, sebete, matšoao a meno, litšepe tsa metsi le liplatelete.
Joalokaha ho se ho boletsoe, li-ion tsa khalsiamo li ama mekhoa ea ts'ebetso ea 'mele' meleng, e bakang:
- ho eketseha ha tlhokahalo ea oksijene;
- ho senya mesifa;
- ho eketseha ho eketsehileng.
Ho fokotsa ts'ebetsong ena meriana, lithethefatsi tse leng sehlopheng sa lik'hamphani tsa khalsiamo (BCC) kapa ha li ntse li bitsoa li-block block tsa calcium.
Lipontšo tsa tšebeliso le phekolo ea BPC
Litokisetso tsa meriana tsa li-calcium channel blockers li behiloe ka pel'a mafu a latelang:
- khatello ea kelello;
- angina pectoris ;
- ho se sebetse hantle;
- Motsoako oa angina le bradycardia;

- Raynaud's syndrome .
Ho phaella moo, BPC e ka laeloa bakeng sa mafu a tsamaiso ea methapo, ho kula, bronchospasme le maloetse a mang a fokolang (lefu la Alzheimer, senile dementia, joala).

Kemiso ea lihlahisoa tsa meriana
Li-calcium channel blockers li na le likarolo tse itseng 'me li arotsoe ka:
- Derivatives ea dihydropyridine. Lithethefatsi tsena li thehiloe ho nifepidine. Li na le phello e atolohang lijaneng tsa boko (Corinfar, Ardalat, Cordaflex, Lomir, Plendil, joalo-joalo).
- Li-derivatives tsa Phenylalkylamine. Sehlopha sa verapamil. Li ama haholo-holo mesifa ea pelo, e fokotsa tumellano ea eona ea tumellano. Phello ea likepe tsena e fokola (Isoptin, Prokorum, Finoptin).
- Li-derivatives tsa Benzothiazinine. Sehlopha diltiazem. Phello ea lithethefatsi tsena e tlaase ho feta ea sehlopha sa pele, empa e arolelitsoe ka bobeli ho pelo le lijana (Dilsem, Cardil).
- Derivatives ea diphenylpyrazine. Sehlopha sa cinnarizine. Hangata, li-CCB tsena li laeloa bakeng sa liso tsa likepe tsa boko (Stugeron, Nomigrain).
Ho phaella moo, bohle ba thibelang litsela tsa calcium tse fokolang ba arotsoe molokong oa pele le oa bobeli, 'me litokisetso tsa dihydropyridine li na le karolo ea boraro. Phapang e ka sehloohong pakeng tsa meloko ke ho ntlafatsa meriana ea meriana le ho fokotsa liphello tse sa rateheng ka mor'a ho nka lithethefatsi. Hape, meriana ea bobeli le ea boraro ea lithethefatsi e fokotsa tekanyo ea letsatsi le letsatsi, 'me e hloka ho sebelisoa feela ka makhetlo a mabeli ka letsatsi. Ho litsela tsa calcium tsa moloko oa boraro ke lithethefatsi tse kang Amlodipine, Latsidipin, Nimodipine.
